Steamship Aeolus Re-Conditioned
Former German Liner, Recently Used as War Transport, Re-
modelled for South American
IBN Elo
ARKING the completion by The Baltimore Dry Docks & Ship Building Company, Baltimore, Md., of one of the most extensive ship repair contracts ever awarded in the history of the United States, with an expenditure of nearly three million dollars involved, the steamship Aeolus, formerly the North German Lloyd liner Grosser Kurfurst, left Balti- more on November 20 on her way to New York, where she was delivered to the Munson Steamship Company for opera- tion in their South American service. In outward appearance the vessel, with its battle-gray hull and white superstructure, presents a very pleasing picture, while an inspection of the various decks will disclose all the comforts and luxuries of the modern and up-to-date ocean liner.
In her entirety this vessel has been renovated; in addition to the remodeling of the quarters, an extensive refrigerating system has been installed which provides for the preservation of the various articles of food consumed during a voyage, as well as a cargo of frozen meats. Finally, in accordance with modern practice, the ship has been converted from a coal burner into an oil burner with a system of thirty-six furnaces operating under natural draft.

Passenger and Freight Service
CROSBY*
Built in 1899 at the yard of F. Schichau, Danzig, Germany, for the North German Lloyd Line, this vessel made her maiden voyage during the winter to Asiatic and Australian ports. ‘The following spring her arrival at New York marked her first transatlantic trip, and from then until the outbreak of the great war in 1914 she plied between New York and Bremen. 5
At the outset of the war she was interned, with other German vessels then on this side of the Atlantic, and later was seized by the United States Government upon our en- trance into the war. The vessel was then turned over to the Navy Department for operation, the name being changed to Aeolus. She was then fitted out as a transport and figured in this capacity until late in 1919.
Her war career included several exciting incidents, one being the occasion when she rammed the steamship Huron, ex-Friedrich der Grosse. Both vessels were in the same con- voy and headed for France when, while pursuing a zig-zag course in the submarine zone, the Aeolus, due to mistaken signals, was forced by another vessel to bear over against the Huron. At the moment of striking, the bow of the Aeolus lifted on the crest of a wave and the resultant damage was that the Huron caught the blow above the waterline on the

starboard side, amidships, thus narrowly averting a serious
catastrophe. Both vessels were forced to put back to New York for repairs but were soon in service again.
Early in 1920 the contract for re-conditioning the Aeolus was awarded to The Baltimore Dry Docks and Ship Building Company, and it is this contract which has just been carried to a successful conclusion.
DESCRIPTION OF THE VESSEL
The Aeolus is a combined passenger and cargo vessel, carrying first, second and third class passengers. She is of the twin screw type, being driven by two quadruple expansion engines with a total of 9,000 indicated horsepower. The
boilers comprise five double end and two single end units.
The machinery is located amidships.

The Aeolus has a total of seven decks. There are two superstructure decks: “A,” boat deck, and “B,” upper prome- nade deck; “‘C,” lower promenade deck, which is a long bridge and poop combined. Below the bridge deck are ““D,” upper deck; “E,’’ main deck, and “F,”’ lower deck, all of which extend fore and aft. Below ‘“F”’ deck there is a “G,” orlop deck, beyond the machinery space and extending to the ends of the vessel. Beneath this is the hold of the vessel.
A flying bridge on top of the pilot house and a docking bridge aft give a commanding view in navigating the ship.
A double bottom extends all fore and aft, subdivided for carrying fuel oil and water. The peak tanks are fitted for carrying water ballast. Below the main deck there are fifteen
oil- or watertight bulkheads dividing the hold into the fol-

lowing compartments: In the forward part of the ship are the fore peak, Nos. 1, 2 and 3 cargo holds, and aft of these are the deep tanks for carrying fuel oil, with a centerline division. Number one and two boiler rooms follow in order, with oil settling tanks on each side and the pump room in between. Then comes the engine room. Aft of the engine room, and below ‘‘G”’ deck, is located the refrigerating machinery space with water tanks on each side. These water tanks extend to the after peak on each side, also between the shaft alleys. Between the main and orlop decks and aft of the engine space, three holds are insulated for carrying frozen meat, and, finally, a space for baggage is provided in the extreme after end of the vessel.
A description of the accommodations provided for the three classes of passengers, the officers and crew shows them to contain everything necessary for the comfort and convenience for the lower classes, and in the case of the higher classes a luxury not surpassed by the most modern hotel. An inspec- tion of the quarters invariably produces exclamations of ad- miration and the details of arrangement prove interesting reading.

JANUARY, 1921
‘The miscellaneous units of the ship’s equipment, as de- scribed below, all tend to make the Aeolus complete in every detail. Safe navigation-is made certain; heating, ventilation, methods of communication and other necessary installations have been taken care of, and, finally, every means of pro- viding for the safety of passengers and crew at sea has been adopted.
OPERATING EQUIPMENT
Navigation—On the navigating bridge, or in the pilot house, are located all the instruments necessary for the safe and efficient handling of a vessel of this size. Within view and easy reach of the officers in charge are the compasses, one magnetic and one gyro; docking and engine telegraphs; engine and revolution indicators; submarine telephones; pneumercators, which indicate the draft and displacement; speaking tube; telephone and call bells to all parts of the vessel, and control cabinets for the fire extinguishing system.
_Pneumercators—A complete pneumercator system has been installed for registering, at gages located in the pump room, the depth and capacity of fuel oil in each tank. An- other pneumercator system, with gages in the pilot house, has been installed .for registering the draft, trim, displacement and deadweight of the vessel.
Steering Gear.—For operating the rudder, a steam tiller is provided, located in the poop at the after end of ‘‘E”’ deck.
The engine is steam driven, with double inverted cylinders.
and is controlled by.a telemotor gear from the pilot house as well as from a station on the after end of “B” deck. °
_ Wireless Telegraph.—Situated on the boat deck, between the two smokestacks, ‘is a steel house in which are quartered the three wireless operators and four cadet officers. This house also contains the battery room and operating room for the wireless telegraph.- An auxiliary generator, gasoline driven, used in connection with the wireless outfit, is located in the upper engine room casing just below the skylight.
Heating and Ventilating—A complete ventilating system.
has been installed on “D” and “E”’ decks, including all as- sembly rooms, quarters, cabins, mess halls, toilet rooms, etc. The mechanical equipment consists of seven supply and six _ exhaust Sturtevant blower sets, each set having a fan driven by an electric motor. The supply sets are also equipped with tempering coils for tempering the air. The distribution of air is accomplished through sheet metal conduits leading to and from the fans to the various localities. All outlets are fitted with plain lattice pattern grills and registers.
Fire Extinguishing System—All fuel oil tanks, except the double bottom tanks, have been equipped with steam smothering pipes leading to a common control manifold on “E” deck. For the cargo holds, including the refrigerated spaces, the “Rich” system for detecting and extinguishing
fire has been installed, with detecting cabinets located in the
wheel house and two control cabinets with steam smothering manifold on “E” deck.
For detecting fire in the passenger quarters, there is pro- vided a patented device with indicators in the pilot house.
Life-Saving Equipment.—To care for the persons on board in case of accident, there are two 20-foot lifeboats and one 30-foot lifeboat of the open type, one 26-foot open motor- boat and twelve 26-foot lifeboats of the decked type, with collapsible sides. All of these boats are placed under patented davits. The lifeboat capacity is sufficient to care for all on board.
Cargo Handling Gear.—Cargo gear for handling cargo to the six hatches consists of two masts and two derrick posts, each mast being fitted with eight wood booms operated by four steam winches, and each derrick post fitted with one wood beom operated: by one steam winch. The ten winches are double cylinder,. single drum, with extended heads.
Anchor and warping gear for handling the anchors con-
sists of a large double cylinder geared windlass, mounted: ©
on the forecastle ‘deck. :.
MARINE ENGINEERING 7
Tor handling ,the heavy Jines with which this vessel. is equipped there are four steam:driven capstans. Two cap- stans are located on the forecastle deck and two on the after end of ‘“C” deck. Bitts, chocks and roller fair leads are generous in number and of beavy construction.
On the boat deck are two steam winches with fair leads to each davit for hoisting the lifeboats.
Generating Plant.—The old electric. generating plant, con- sisting of three German 35-kilowatt generators, driven by re- ciprocating steam engines and one 35-kilowatt General Elec- tric turbo-generator, have been overhauled and re-arranged. A new 100-kilowatt General Electric turbo-generator has also been added.
Machine Shop.—On the port side of No. 2 boiler hatch, on “KK” deck, is a completely equipped machine shop.
Laundry.—On the starboard side of No. 2 boiler hatch, on “KE” deck, is provided a laundry of ample size to care for the needs of the entire vessel.
PROPELLING MACHINERY
_ The machinery of the Aeolus, hereinbefore mentioned, con- sists of the following:
The two quadruple expansion marine engines, with a total of 9,000 indicated horsepower, and driving two 17-foot 9- inch diameter propellers, have been thoroughly overhauled and put in first class condition.
Five double end boilers, 14 feet 2 inches diameter and 20 feet long, and two single end boilers, 14 feet 2 inches diam- eter and 10 feet 3 inches:long, each built for a pressure of 220 pounds, have been converted from coal to oil burning.
The fuel oil burning equipment is of the mechanical atomizing type, two sets being furnished, each being capable,
of supplying the whole boiler plant, and éach set consisting of the following:
_ Two 7¥%-inch by 4'%-inch by i0-inch horizontal duplex oil service pumps.
Three oil heaters.
One suction strainer.
One discharge strainer.
One oil meter.
One regulating valve.
One steam trap.
Three thermometers.
Two pressure gages.
Both fuel oil sets, as well as a 10-inch by 10-inch by 12- inch horizontal duplex fuel oil transfer pump and all fuel oil manifolds, are located in the pump room, which is en- tirely watertight. This condition contributes greatly to the safety of the vessel, as with this arrangement either boiler
room may be flooded while the other may still be served from:
the pump room. :
Two old feed pumps, the grease extractor and feed heater -
have been removed and replaced by two 18%4-inch by 13%4-
inch by 24-inch vertical simplex feed pumps of Worthington +
make; one Row & Davis feed water filter and grease ex- tractor and one Row & Davis No. 36 Paracoil 2-pass feed water heater. A 10-inch by 20-inch by 16-inch vertical simplex featherweight auxiliary air pump, Worthington make, has been installed and oil fire pump has been replaced by a
12-inch by 14-inch by 12-inch vertical duplex Worthington
pump.

behind and in tandem torthe-steam cylinders~of a tandem compound steam engine. The carbon dioxide cylinders are 6% inches bore by 18 inches stroke and the steam cylinders are. 13 inches and 24 inches in diameter respectively for the high pressure: and low pressure and 18 inches stroke. Each of these machines. has a rated capacity of 80 tons refrigera- tion at 80 revolutions per minute, and together with the con- densers-and:evaporators each has ample capacity to take care of the six cargo holds, small refrigerator boxes in first and second class galleys, first class bar, an ice-making tank and an ice water circulating system. Actual cooling in the re- frigerated spaces is done by the cold brine circulating method, the brine being cooled by the expansion of the carbon dioxide _gas in the evaporators.
The refrigerated cargo holds are located at Nos. 4, 5 and 6 hatches between “E,” “F”’ and “G” decks and are designated as F-4, G-4, F-5, G-5, F-6 and G-6. Their total capacity is approximately 102,000 cubic feet and they are piped with 14-inch brine pipe at a ratio of 4 cubic feet of space per lineal foot of pipe, making a total of approximately 26,000 cubic feet of pipe.
rz f >
CARBON DIOXIDE COMPRESSORS
The two carbon dioxide compressors are located in a room under hold G-4 just aft of the dynamo room. G-4 is divided in half by an athwartship insulated partition. ‘The after half into which No. 4 hatch opens is devoted to refrigerated cargo and the forward half is used as condenser and evap- orator room. This forward half is further divided by a fore and. aft insulated partition, thus making two rooms.. The two condensers and condensing water pumps are located in the starboard room and the two evaporators, brine pumps, the brine return tank and the brine feed header are located in the-port side room. Entrance to the compressor room is had by means of a small hatchway in the floor of the condenser room with a stair leading down.
The crank shafts of the carbon dioxide compressors are of the double bearing single throw type with fly wheel mounted between the bearings. The compressor cylinders are made from a solid block of nickel steel bored true and ground smooth through ‘the working barrel and are fitted with nickel steel suction and discharge valves working in nickel steel cages. High and low pressure steam gages, vacuum gage and brine pressure gage are located in the engine room within easy view of the engineer and a carbon dioxide high pressure alarm:gage was provided which sounds an electric alarm in case of an abnormally high pressure. Steam at 150 pounds pressure is used, being taken through a reducing valve from one of the ship’s steam lines carrying boiler pressure at 200 pounds pressure and exhaust line is connected to one of the ships condensers, the steam engines thus operating condensing.
CONDENSERS
There are two carbon dioxide condensers of the shell and coil type with removable heads, each containing 5,032 feet of 34-inch extra heavy copper pipe made up in twelve sepa- rate coils. Two duplex steam driven water pumps, size 7 inches by 7% inches by 10 inches, each having a capacity of 300 gallons per minute, furnish water for these condensers. Sea water is used for condensing and it is taken from a suc- tion line through the ship’s side and discharged overboard after passing through the shells.
In the condenser room there is a set of high and low pres- sure carbon dioxide gages for each compressor and the neces- sary carbon dioxide charging apparatus consisting of an- other gage, scale and heating tank, etc. All steam and water lines are made of copper pipe and thermometers are pro- vided where necessary to aid the operators in securing proper operation.
The .evaporators are of similar construction to the con- densers and consist of two shells, containing extra heavy
JANUARY, I9Q21
iron pipe, however, in place of copper pipe. Each shell con- tains.6,988 feet of 1-inch extra heavy pipe made up in twelve coils. ‘There are two brine pumps, size 714 inches by 10% inches by 10 inches, duplex steam driven, each haying a capacity ‘of 300 gallons per minute. The bases of these’ brine pumps are provided with extension pieces and the pumps are {ccated so that the steam cylinders are in the condenser room and the brine cylinders in the evaporator room and the in- sulated partition is built around the beds of these pumps. This does away with the cumbersome insulation over the steam cylinders of the pumps which is necessary when the pumps are placed in the cold room.
BRINE MaINns
Warm brine leading from the various refrigerated holds, ice tank and boxes comes into the evaporator room through l-inch mains and pours into a return tank. The brine pumps take it from this tank and force it through the evaporators, where it is cooled again and it then passes to the feed headers. From this header i -inch feed mains carry brine to all parts of the ship where refrigeration is required. Every feed and return main has a control valve, and designating boards are provided on the feed header and return ‘walk showing exactly what each valve controls. Thermometers are provided on each return main and the return tank, as well as on the inlet and outlet of the evaporators.
There is a brine heater to warm the brine when defrosting the coils in the refrigerated spaces. It is made of cast iron shell with a special steam coil inside and so connected that it can be cut in and out at any time desired.
‘TEMPERATURES OF REFRIGERATED SPACES
A temperature of 15 degrees F. is maintained in cargo holds F-6, G-6, F-5, G-5 and G-4, these being designed for carrying frozen beef. Hold F-4 is subdivided into four rooms for carrying ship’s stores, such as meats, eggs, butter, cheese, vegetables, etc., and temperatures are maintained in these rooms to suit the nature of the contents. Thermometer tubes lead froth the refrigerated holds up to “B” deck with two thermometers in each hold hung on brass chains fastened to deck blocks. ‘This makes it possible to take temperatures in the holds by opening the deck blocks and pulling up the thermometers.
The 1%-inch brine piping in the holds is arranged in ceiling and wall coils connected in circuits averaging 1,200 lineal feet each and fed from the brine header in the evap- orator room. Removable hatch coils are provided with spe- cial four-way brine cocks on each coil, so constructed that a coil can be cut off and removed without losing any brine. Watertight ferrules are provided where feed and return mains pass through decks and bulkheads on way to evaporator room.
There is a scuttle butt for cooling drinking water. It con- sists of a round galvanized tank with spiral brine coils inside and the water is continuously circulated to drinking fountains in all parts of the ship by means of a 1-inch centrifugal motor driven pump. ‘There is also a duplicate pump which is used asa reserve.
The ice making equipment has a capacity of one-half ton per day and is used for making ice for table use, etc.
There is a three-compartment refrigerator installed in the first class galley, two-compartment box in the second class galley, and a small box in the first class bar. These boxes are piped with l-inch brine coils and also fed from the main header in the evaporator room.
INSULATION
All refrigerated spaces are insulated with compressed cork- board insulation. In the holds F-4, F-5 and F-6, 2-inch by 3-inch wood grounds were bolted to the ship’s frames on ceil- ing and walls witha layer of 7£-inch tongued and grooved sheathing nailed to this followed by layer of 3-inch and then a layer of 2-inch corkboard. This was then finished by a
JANUARY, 1921
layer of 11-inch tongued and grooved spruce sheathing. Waterproof paper was placed between each layer of sheath- ing in coils and between the courses of 2-inch and 3-inch corkboard. The spruce sheathing was finished with two coats of shellac.
An insulated ribbon was built around the ship’s sides and exterior bulkheads on “F” deck extending 3 feet from the ship’s side.
The insulation of G-4, G-5 and G-6 is similar to the “F” deck, with the exception of the floors, where 6 inches of cork- board with two layers of 3 inches each was laid in hot pitch and a finished spruce flooring was nailed to ground imbedded in the coils. A 3-inch hardwood floor was built under the hatches extending out 1 foot each way beyond the edge of the
hatch in order to secure protection to the insulation when load- ing cargo. Heavy beveled yellow pine timbers were bolted to the hatch coamings and strong backs and removable insu-
lated plugs fitted in them so that when cargo is loaded the holds can be completely sealed up.
Proper tests were run on the refrigerating equipment con-
sisting of an 18-hour run while the ship was at anchor and a 12-hour operation during the sea trial of the ship when it was taken to New York. On reaching New York another 24-
_ hour trial was run. In all the tests highly satisfactory results were secured. The desired temperatures were easily obtained in all the refrigerated spaces and the operation of all the re- frigerating equipment was found to be all that could be de- sired.
Taken all in all, the Acolus, completely equipped in every detail, should, under the operation of the Munson Steamship Company, to which she has been allotted by the United States Shipping Board, prove popular with tourists and travelers and serve to cement our friendly relations with the South American countries. As she now stands, the Aeolus in her re- conditioned state is a credit not only to the Baltimore Dry Docks & Ship Building Company and to her operators, the Munson Steamship Line, but also to the merchant marine of the United States.
Steam Engine Driven Exciter Sets
HE recent application of alternating current propulsion
equipment to the Eclipse, the first of twelve ships to
be, similarly equipped by the United States Shipping Board,
has called attention to another use for the small direct current steam engine driven generating set aboard ship.
Hitherto the marine application of these sets has been more or less confined to lighting purposes, but on these vessels they have been applied to supply energy for several different pur- poses. Two 35-kilowatt sets of this type have been installed on the Eclipse to furnish field excitation current to the al- ternator, besides which they furnish 125-volt, direct current power to operate contactors on the control board and to run the blower motor.
_ Generating sets similar in design to these, and ranging in capacity from 2% kilowatts to 60 kilowatts, are made by the General Electric Company, primarily for marine purposes. They are, however, equally adaptable to various uses on land, such as supplying light and power in isolated plants and shipvards and as exciters for alternating current gener- ators in central stations.
The complete set consists of a single cylinder steam engine directly connected to a direct current generator. The cylinder and stroke of the engines vary from 3'% inches diameter by 3 inches stroke for the 214-kilowatt size to 12 inches by 11 inches for the 60-kilowatt size. Only one valve is used, and a short stroke has been adopted. The cylinders are separate from the column casting. Since the ports are short and direct, small clearance space is allowed. Automatic relief valves, to relieve water under ordinary operating conditions, -and separate hand operated drain valves are fitted to each
MARINE ENGINEERING 11
end of the cylinder. The steam distribution is accomplished through a single balanced piston valve, driven either by an eccentric strap or by a pin from the governor weight. Governing is accomplished by two methods, depending upon the size of the engine. The 3¥%-inch by 3-inch, 47%2- inch by 4-inch, 11-inch by 8-inch, and 12-inch by 11-inch cylinder engines are equipped with a flywheel type automatic governor, while the other sizes, from 5-inch by 41-inch to 9-inch by 7-inch, have an enclosed type which is inside the column. In the latter type the piston valve is connected to
Exciter Sets on the Eclipse
the governor by an eccentric strap. The length of the valve stroke depends upon the distance of the center of the eccentric from the center of the shaft, and therefore the amount of steam admitted to the cylinder varies directly as the distance between centers. That is to say, the shorter the valve stroke the smaller the amount of steam admitted. If the speed reaches a dangerous point, the throwing out of the governor makes the valve stroke so short that no steam is admitted to the cylinder.
LUBRICATING SYSTEM
The lubricating system also differs with the capacity of the engine. Those in the range from 2% to 5 kilowatts em- ploy a gravity system, the oil being contained in a con- veniently located tank and supplied to the various bearings by a number of sight feed tubes. The other sizes are equipped with a forced lubrication system, which functions as follows: The bottom of the column, or crank case, forms an oil tank of large capacity and radiating surface. A small single act- ing plunger pump driven by an eccentric which is bolted to the crank shaft forces the oil, under pressure, to the various bearings of the engine. From the bearings the oil escapes and is collected again in the bottom of the crank case, where it cools, and is used over again.
The engines can be operated on pressures up to 125-pound gage, either condensing or non-condensing. When the pres- sure is above 125 pounds a reducing valve should be used. These engines will operate successfully on moderately super- heated steam as used aboard ship.
All parts which would be seriously damaged by corrosion due to the action of salt air are either made of corrosion re- sisting material or given a protective treatment. The gen- erators are regularly wound for either 110, 125 or intermediate voltages, and the series windings on the field spools will allow of over compounding up to 5 percent of normal, by means of a German silver shunt connected across the field terminals.
New Design of 10,000-Ton Tanker
Tankers Built on New Transverse System of Framing Designed by Chief Surveyor of British Corporation
HE accompanying plans illustrate a new type of tank steamer, several of which are at present being con- structed by Sir W. G. Armstrong Whitworth & Company, Limited, at their Armstrong yard, Newcastle-on-Tyne, Eng- land. This firm, which has had a long and varied experience in the construction of tankers, having built more vessels of this type than any other firm, has been entrusted by British Tanker Company, Limited, with the construction of several vessels of this new type. The efficiency and reliability of
the service of the previous tank steamers built by this firm.
is an augury of the success of these vessels.
Each of these vessels is built for the carriage of oil in bulk and a special feature of the design is that cargoes rang- ing in density from 35 to 51 cubic feet per ton can be carried without leaving any of the main compartments empty, thereby avoiding a condition productive of severe straining actions upon the structure. This desirable arrangement has been ob- tained without increasing the free surface beyond that usually found in tank steamers of this size.

GENERAL ARRANGEMENT
Each vessel is of the two deck type with poop, bridge and forecastle, the poop being of sufficient length to cover the engine and boiler space.
The oil forming the cargo is carried in nine double tanks divided into three groups by two pump rooms. Stowage for oil fuel is provided in two cross bunkers, one forward and one aft, and when it is desired to undertake voyages of exceptional length additional oil fuel can be carried in the forward deep tank. A cofferdam is worked at each end of the cargo tanks and cross bunkers, and between these limits the main deck is parallel to the base line, the height of *tween decks being determined by the capacity required for the oil of greatest density provided for.
The total capacity of the main holds with their expansion trunks is sufficient for a full cargo of petroleum, but the tanks at the sides of the trunks must be utilized when carry- ing spirit. Each main tank and each side tank is fitted with a separate hatchway, those to the side compartments having deep coamings to serve as expansion trunks.
In addition to the stowage arranged for oil fuel, coal bunk- ers are fitted in the ’tween decks directly over the boilers with chutes leading to the stokehold.
Water ballast can be carried in the fore peak, after peak, fore deep tank and double bottom tank under the engines. Boiler feed make up water is carried in the double bottom under the boilers.
The space forward between the upper deck and the top of the deep tank is fitted as a cargo hold.
Ample storeroom space is provided throughout the vessel.
The vessel has two masts, each carrying two derricks, one on the fore side and one on the after side, and two steam winches for working these derricks. A large warping winch is also fitted on the poop deck aft.
In addition to the usual bollards, a large towing bollard is fitted at the after end of the vessel, with a bridle arrangement to the wing bollards, so that derelicts may be taken in tow.
ACCOMMODATIONS
The accommodations, which are more elaborate and ex- tensive than is usual in vessels of this type, are arranged as
_ follows:
Seamen and firemen in the forecastle and on the upper deck forward, the men being berthed not more than two in ene room. ‘The mess rooms are commodious and every atten- tion: has been paid to the sanitary and washing arrangements.
Officers. are accommodated on the bridge deck, upper bridge
and flying bridge in large and airy rooms, their comfort hay-
ing been specially considered. The engineers’ quarters are situated in the poop aft of the
engine casing, the style and fittings being similar to that of - the officers.
Petty officers’ quarters are also arranged in the poop, at
the sides of. the engine casing, as are their mess room, en-
trances, etc.
Storerooms, hospital, etc., are placed in the bridge with doors opening directly to the deck.
The galley is fitted in the engine and boiler casing and equipped with all necessary cooking appliances.
Refrigerating machinery and cold chambers are arranged on the second deck aft of the engine room, the machine being placed in such a position as to be constantly under the supervision of the engineer.
HULL
One of the unique features of the vessel is the structural framing which is being carried out on the Foster King trans- verse system. For many years the transverse system of con- struction in oil tankers has suffered as compared with the Isherwood longitudinal system on account of the greater weight of structure in the former as compared to the latter. J. Foster King, of the British Corporation, has patented a system of transverse framing in which the total weight will certainly not exceed that of the longitudinally framed vessel.
JIn this system a number of deep longitudinal girders are fitted to the bottom and sides of the vessel and also to the center bulkhead. At the transverse bulkheads these girders are carried athwartships, while one or more deep floors are arranged in each oil compartment according to its length. The deep girders on the transverse and fore and aft bulk- heads are so arranged that alternate tanks are left clear for calking.
The transverse framing has been reduced, and, as already stated, a considerable saving in the structural weight has re- sulted compared with the old transverse framed tanker. In addition, the erection has been simplified and the riveting reduced to a minimum.
Matn PROPELLING MACHINERY The vessel is propelled by a single set of triple expansion engines of 3,000 indicated horsepower having cylinders Li inches, 46 inches and 77 inches diameter by 51 inches stroke. A complete set of auxiliary machinery is being installed.
BOILERS
Steam is generated in four watertube boilers of the Babcock and Wilcox type working at a pressure of 200 pounds per square inch with a closed duct forced draft arrangement, the-

furnaces being fitted for burning oil and coal. The boilers are of such size as will enable them to supply steam to various oil tanks for cargo heating, a complete system of heating coils being installed having sufficient heating surface to liquefy the heaviest class of oil carried.
FUEL Or SYSTEM
The fuel oil pumping arrangements have been well con- sidered. A large transfer pump is fitted in the fore pump room capable of drawing fuel from the deep tank, fore peak and fore and after cross bunkers and discharging to deck or overboard as necessary. This piping is so arranged that oil can be pumped from any one of these tanks to any other. By this means a level keel can always be maintained irrespective of the class of cargo carried.
Two settling tanks, each containing one day’s supply, are arranged at the after end of the summer tanks abreast the after cross bunker.
Arrangements are also being made for the burning of low flash oil, the details of which cannot be published at present, but which will be such as will meet the classification society and Board of Trade requirements and prove efficient in service.
Carco PUMPING ARRANGEMENT
Great attention has been paid to the oil pumping arrange- ments. The cargo oil is dealt with by three oil pumps, each capable of discharging 300 tons of oil per hour, even when pumping the heaviest class of oil. The oil piping is arranged so that the pumps can deal with the oil in every conceivable way, large double suction pipes being fitted to each tank,
Electric Steering Gear on Standard Oil Company Barges HE three steel barges Buffalo Socony, Rochester Socony and Utica Socony built for the Standard Oil Company of New York by the Bethlehem Shipbuilding Cor- poration, Limited, present two notably outstanding features in that they are self-propelled and electrically steered. They are designed to carry oil in bulk and will be placed in service on the New York State Barge Canal. E
These barges are 156 feet long and are listed at 690 tons deadweight. They are driven through a single screw, and the propelling power is furnished by an oil engine which also runs a generating set of sufficient size to furnish the electricity required to operate the electric steering gear.
The electric steering gear is of the drum type, specially de- signed to combine light service with a very compact arrange- ment, giving flexibility of installation and economy of space. It was designed by the auxiliary machinery department of the Bethlehem Shipbuilding Corporation, Limited, and built at their Moore plant, Elizabethport, N. J. All working parts of the steerer, including the motor and brake, master switch, drum, handwheel and the required gearing, are mounted on a single base measuring 25 inches by 4134 inches. This com- pact arrangement makes it possible to place the entire gear in the pilot house.
The motor which drives the steering gear is of the com- pound wound, direct current type, rated at 3 horsepower, 110 volts. It is provided with ball bearings and is suitable for 100 percent overload for five minutes. The motor is con- trolled by means of a magnetic control panel operated by a master switch at the steering stand. A shift of the master switch to the right or left causes the motor to be operated through the magnetic panel in the required direction. Power is transmitted from the motor through triple gears and drum to the quadrant on the rudder stock by means of a 34-inch extra flexible steel wire rope. When the switch is brought

discharging to each side of the deck and over the stern, the total number of discharges being nine. Drain valves are fitted in the summer tanks, each of these valves being con- trolled from the upper deck. ;
The details of this system are all in accordance with the builders’ latest and most approved practice.
A large ballast pump is placed in the forward ballast pump room for dealing with the water ballast in the fore deep tank and fore peak.
An efficient system of gas freeing and vapor pipes has been arranged throughout the oil compartments and every pre- caution taken to reduce the possibility of fire due to danger- ous gases.
ELECTRICAL INSTALLATION
The electrical installation consists of two steam-driven generating plants, each dynamo being of ample size to run all lights, wireless, fans, steering gear, workshop machinery, etc., without heating.
Electric fans, bells and telephones are fitted throughout the vessel.
Life saving appliances are of the most up-to-date type, Welin davits being fitted for working the four lifeboats and motor launch.
The usual deck machinery is installed, the principle de- parture from the average tank vessel being that an electric hydraulic steering gear is fitted on the rudder head. and con- trolled from amidships by telemotor gear.
The fittings throughout the vessel will be of first class make and description and there is little doubt that the vessels, when completed, will prove to be highly successful and efficient.
back to the central, or off, position, the line is disconnected and the motor is stopped by means of a quick-acting shunt brake. Electrical dynamic braking is also provided.
A rudder indicator mounted on the framework of the steerer shows the position of the rudder at all times. When

the rudder reaches a hardover position a gear limit switch disconnects the power, stops the motor and prevents damage due to operating the steering gear beyond the working rudder, . angle.
The steerer is provided with a 60-inch handwheel for use

when it is desired to steer by hand. Shifting from electrical steering to hand steering is accomplished by moving a clutch wheel, which shifts two jaw clutches so that when the hand steering wheels are connected to the drum the motor is simul- taneously disconnected, and vice versa. When the gear is connected up for hand steering the clutch is held in place by a spring latch, so that when it is desired to shift to electrical
JANUARY, 1921
steering the spring latch is raised and a steel coil spring automatically moves the clutches to the required position. This renders it impossible for the motor and handwheel to be connected to the drum at the same time and eliminates all danger of accidents from this source.
This type of electric steering gear is suitable for service on river barges, yachts or any other light draft vessels.
The Motorship Narragansett
10,000-Ton Tanker Equipped With Oil Engines Using the Vickers System of Solid Injection of Fuel Oil
HE Narragansett, a motor-driven oil tank vessel built
by Messrs. Vickers, Limited, at Barrow-in-Furness
for the Anglo-American Oil Company, Limited, carries 9,420 tons of cargo plus 520 tons of fuel and stores.
PRINCIPAL DIMENSIONS The principal dimensions of the vessel are as follows:
Length between perpendiculars........... 425 feet o inches Brenan, m@kdledl oocoodosconsevcocacv000c 56 feet 8 inches Depth to upper deck, molded.............. 33 feet o inches IMeantidnaitenas sete aeeiion: Gecko cone 26 feet o inches Displacement at mean draft............... 14,000 tons Weadweichticapacityaneeee eae een eer neeE 10,050 tons Contractispeed' vamos cee Oe eae 10.5 knots
Speed on trial over measured mile........ 11.24 knots The hull is constructed on the Isherwood system with a long poop and a short bridge and forecastle with connecting gangways. Fuel bunkers are arranged abreast of the ma- chinery space on the tank deck aft and there are ten main tanks for oil fuel. Main ENGINES
Two Vickers six cylinder four cycle, solid injection motors are installed aft, each developing normally 1,250 brake horse-

power at 118 revolutions per minute and having cylinders 24% inches diameter and 39 inches stroke.
Heavy cast iron columns are employed for the framing, representing a modified submarine trestle design with col- umns over the main bearing, the columns being continuous athwartships, although relatively thin between the front and back. Within these hollow columns are long steel tie- rods and the cylinders are separately cast and bolted to- gether.
The liners and cylinder covers, which are separate, are of special cast iron, and a feature of note is the provision of diaphragm plates under the cylinders to prevent waste of lubricating oil. The liners are free to expand downwards.
FuEL O1 System
The engines are fitted with the Vickers patent system of solid injection of fuel oil which entirely dispenses with the use of compressed air for fuel injection purposes. The prin- ciple lies in forcing fuel oil at about 4,000 pounds per square inch into the cylinder through a special type of valve in the cylinder cover. The fuel is supplied under this pres- sure by means of a small battery of four pumps discharging to a common rail with branches leading to each cylinder.

CoNTROL MECHANISM
The control of the pressure of oil fuel is effected by regu- lating the closing point of the suction valves of the pumps.
The camshaft is driven by spur and bevel gearing from the center coupling of the crankshaft.
Reversibility is obtained by the sliding camshaft method, two side by side cams being provided for each valve. The valves are operated by levers mounted on the maneuvering shaft and actuated by the cams on the camshaft. The gear is placed in the reverse position by means of a servo-motor comprising a compressed air power cylinder and an oil buffer cylinder. Suitable mechanism is arranged between the servo- motor and the fulcrum and camshafts, so that when the servo- motor operates all the movements required for reversing are carried out in their proper order. A hand reversing gear is provided for use in the event of failure of the power cylinder, in the form of a hand pump operating on the oil buffer cyl- inder.
All the essential controls are interlocked, and only when the complete movements have been effected is it possible to operate the starting wheel. Rotating of the starting wheel

first admits compressed air to all cylinders; further rotation - cuts off air and admits fuel to the cylinders in pairs.
A hand lever is provided at the control station for con- trolling the speed of the engine, which is effected by regulat- ing the opening of the fuel valves.
CooLinc SysTtTEM
Salt water is used for both the cylinder and piston cool- ing, this water being supplied by pumps worked by sway beams from the forward crosshead of each engine. Above the main pumps are mounted booster pumps to give addi- tional pressure to the piston cooling water. Bilge and sani- tary pumps are also worked by the sway beams. The supply to the pistons is taken through telescopic pipes, and the out- flow is taken to funnels mounted on the columns.
LUBRICATION
Forced lubrication is applied to all the crankshaft and crosshead bearings by means of two electrically driven re- ciprocating pumps. For the lubrication of the pistons, force pumps of the sight feed multiple plunger type are provided.
