Latest Data - New Marine Work Information on New Ships Ordered—Building and Repair Con- tracts Let—Shipping Board Loans Made, Authorized or Pending CCORDING to a report of the A department of commerce, on June 1 American shipyards were building or under contract to build for private shipowners 121 ves- sels aggregating 369,685 gross tons, compared with 183 vessels aggregat- ing 396,886 gross tons on May l. Following is a summary showing the number and gross tonnage of steel vessels under construction or con- tract for private shipowners on June 1. Three passenger and cargo vessels of 17,500 gross tons each were un- der construction by the Bethlehem Shipbuilding Corp. for the Oceanic Steamship Co. Three passenger and cargo vessels of 7200 gross tons each were also under order with the same yard for the United States Mail Steamship Co. The Bethlehem com- pany also had under construction one tanker of 1534 gross tons for the Standard Transportation Co. The Federal Shipbuilding Co. was begin- ning a program of construction of four passenger and cargo vessels of 11,000 gross tons each for the Grace line. The Newport News Shipbuild- ing & Dry Dock Co. was building two 21,900 gross ton passenger and cargo vessels for the Dollar Steamship Co.; was under contract to build three 7500 gross ton passenger and cargo vessels for the United Mail Steam- ship Co.; and was building two 5700 gross ton passenger and cargo ves- sels for the Eastern Steamship lines. The New York Shipbuilding Co. was under contract to build two pas- senger and cargo vessels of 30,000 gross tons each for the United Line Inc. The Sun Shipbuilding & Dry Dock Co. was building four tankers of 9000 gross tons each for the Mo- tor Tankship Corp. and one passen- ger and cargo vessel for 8272 gross tons for the American South African line. This makes a total of 25 steel vessels, aggregating 301,606 gross tons under construction or contract by American shipyards for private owners. Begin Work on New Fireboat Fire Commissioner John J. Dor- man drove the first rivet in the keel of New York City’s fire boat now under construction at the Tebo Yacht Basin in Brooklyn and officially set under way the building of a craft which it is said will have greater capacity than any marine fighter in this country. The 130-foot vessel will be de- 62 livered at a cost of $582,500. It will have a beam of 26 feet, a draft of 7% feet and will be equipped with five Sterling engines developing a total of 2740 horsepower. The mo- tors will operate on two electric units generating 1163 horsepower which will drive the craft at 18 miles per hour. Designed by Henry J. Gielow Inc. and classified under the American Bureau of Shipping, this new craft will be capable of throwing 16,000 gallons of water per minute. It will be self protected by a system of sprays. Fuel tanks will be housed within encasements which will be guarded by carbon dioxide fire pre- vention equipment. It is expected that the vessel will be placed in serv- ice in the fall. : New Cunard Super Liner Will Be World’s Largest Additional details concerning the new $30,000,000 giant Cunarder, now building on the Clyde, reveal that the old British company is leav- . ing nothing undone to recapture the Atlantic Blue Ribbon it lost to Ger- many after more than 20 years. Not only is the vessel designed for rec- ord-breaking speed but she will be the biggest liner in the world. The new vessel will be 1018 feet long, with a beam of 115 feet and 73,000 gross tons. High pressure, superheat turbines, generating 20,- 000 horsepower will, it is reported, drive her at a speed of between 32 and 35 knots. Not only has the Cunard line de- signed the vessel to be the biggest and swiftest afloat, but no expense is being spared in making her the most luxurious and comfortable vessel pos- sible. Approximately $2,500,000 will be spent on her interior decorations and $1,000,000 for a gyro-stabilizer weighing 300 tons. This vessel is the first of two sister ships. It is expected that the keel of the second will be laid some time next year. Two vessels of this speed will make possible weekly express sailings from New York, Southamp- ton and Cherbourg. They will ac- tually do the work of the three big ships which are maintaining the company’s weekly express sailings at the present time. The new Cunarder will accommodate 5000 passengers. The biggest liners now in service carry a little more MARINE REview—August, 1931 than 2000 passengers on the average. Externally the outstanding points of the new Cunarder will be found in her bows, funnels and decks. The bows will be of the bulbous type, de- signed to give greater speed and to reduce rolling. The three funnels will be of graduating heights, the first the tallest, the second several] yards lower and the third still lower. This plan was evolved after many tests to make sure that the smoke will pass over the decks in the worst winds. Ten miles of carpet will be used for deck coverings. She will have 10,000 electric fittings and 30,000 tons of steel will be used in her con- struction. Her power station will produce enough electric current to provide light for a city of 100,000 people. The catering department will boast 200,000 pieces of crockery. Tableware, including knives, forks, spoons, etc. will total 100,v0v0 pieces. The vessel’s stern frame, al- ready made, weighs 100 tons and is the world’s biggest casting. The new Cunarder will be launch- ed early next year and will sail from Southampton on her maiden voyage to New York in October of 1933. Hold Successful Trials The’ electrically-propelled _light- house tender, Linpen, for use py the United States government, bu- reau of lighthouses, in buoy and sup- ply work in Chesapeake Bay and its tributaries successfully completed its trials on July 20, and will soon go into service. The boat is of steel construction, approximately 120 feet long, with 25- foot beam, and was built by the Mer- rill Stevens Drydock Co. of Jackson- ville, Fla. The power plant consists of two Winton diesel engines driving two 100-kilowatt, 250-volt; 400-revo- lutions per minute electric genera- tors which supply electricity for all purposes, including propulsion, lighting and the operation of auxili- aries. The Linpen is driven by a single screw propeller direct connect- ed to a 240 horsepower driving mo- tor operating on 500 volts at 350 revolutions per minute. This is of double unit construction. Complete electric equipment was furnished by the General Electric Co. The control is of the armature control type, with a station in the engine room. PRY MER ye Se ee
