Two Tankers Laid Down To Have 15-Knot Speed It is reported that the Sun Oil Co. has begun the construction of two new tankers at the Sun Shipbuilding & Dry Dock Co., Chester, Pa, In dimensions the new vessels are to be identical with other tankers built in recent years for the same company. The hull particulars call for a length overall of 497 feet, 10 inches; beam molded, 65 feet, 9 inches; depth molded, 37 feet; draft, 27 feet, 2 inches; displace- ment loaded, 18,000 tons; gross ton- nage, about 9000; and cargo capacity of about 113,000 barrels. In one important respect the new tankers will differ from those previ- ously constructed. The speed is to be stepped up from the customary 11 or 12 knots to 15 knots. The propelling power will be Sun-Doxford diesel en- gines applied to single screws and of increased power to give this speed. The present tankers are fitted with en- gines developing 2800 horsepower at 80 revolutions per minute. To obtain the increased speed the engines for the new ships will probably develop from 4000 to 4500 brake horsepower: Improvement in the Sun Oil Com- pany’s tanker operations is cited as the immediate reason for the new con- struction. Not only has the company recently placed all of its idle tankers in operation, but it has been neces- sary to charter three tankers from other companies in order to handle in- creased business. Order Two Gasoline Barges The United Dry Docks Inc., New York, has received an order for two 11,000 barrel nonpropelled gasoline barges to be built on the reverse chan- nel system for James McWilliams Blue line. The dimensions are: length overall, 170 feet; beam, 38 feet, 114 inches; depth, 14 feet, %4 inches; loaded draft, 10 feet. Sides and bot- tom are to be constructed of 18-inch by 38.1 pound channels. The bilge, ‘with a radius of not less than 12 inches, is to be of %%-inch plating. Electric welding will be used in con- struction throughout. The hull will have eight transverse bulkheads, the fore peak and after peak bulkheads being located 22 feet from foreward and after ends respec- tively. The remainder of the bulk- heads are to be spaced 18 feet apart. A longitudinal bulkhead extending from fore peak to after peak trans- verse bulkheads will divide the cargo space into eight compartments, four port and four starboard. The com- bined cargo capacity of the tank com- partment is 11,000 barrels. These barges will be built to Ameri- can Bureau of Shipping class for limited coastwise service. Electrically Welded Ship The largest electrically welded steel ship constructed in this country, ac- cording to John H. Odenbach, presi- dent of the Dolomite Products Co., is to be launched early in July at Ro- chester, N. Y. The vessel is 213 feet in length overall 32 feet in beam, 13 feet, 4 inches in depth and has a draft fully loaded of 9 feet, 6 inches. The minimum draft permitting the ship to clear bridges is 6 feet, 6 inches, while the draft in light condition is 4 feet, 6 inches. The cargo capacity is 1200 tons and the ballast tank capacity is 600 tons. Propelling machinery is of twin screw diesel electric type. Two Busch- Sulzer, four-cycle, air injection, six- cylinder diesel engines, each rated at 440 brake horsepower at 360 revolu- tions per minute, drive two Diehl] 250 volt generators supplying current to two Diehl propelling motors, each of 350 horsepower. The new vessel is to operate on the Great Lakes and the Barge canal. An illustrated and complete description of this vessel will be published in a later issue. Pittsburgh Coal Co., Pittsburgh, has been authorized by its directors to build a new Ohio river towboat. AS this is written no additional informa- tion is available, but it is assumed that the new boat will be of custom- ary design and construction, Tanker Construction Seen For Replacements There are a number of evidences of interest in tanker construction. Ten- tative proposals have been made, it is understood, for two exceptionally large tankers for the Cities Service Transportation Co. and for one 16,000- ton tanker for the Sinclair Naviga- tion Co. Several of the other leading oil com- panies are also said to be planning tanker construction. As the life of a tanker, depending on its service, cannot be much over 15 years, it is going to be necessary either to replace some of the older vessels with new construction or to elaborately rebuild by inserting a new hull body between the ends, which have not been affected by the corro- sive action of oil carrying. In this way another 74% years might be added to the life of a tanker and the expense would necessarily be considerably less than for new construction. In any case it may be confidently expected that there will be consider- able activity in connection with tanker construction and renovation in the near future. Shorten Oil Tanker To make the Texas Company’s steamship MaAtInr available for service on the Great Lakes, the Robins plant of the Todd Shipyards Corp., New York, was awarded the job of shorten- ing the tanker to enable her to pass through the St. Lawrence canals. The bow was shortened 53 feet and the stern counter 4 feet. Shortening of the bow necessitated the elimina- tion of the forward fuel oil tanks, cargo holds, No. 1 cargo tank, and No. 1 summer tank. The new bow was faired into the old structure well aft in No. 3 cargo tank, or approximately 116 feet aft of the original stem. The original vessel is longitudinal in frame but the new bow structure is of trans- verse frame construction. Forecastle head and deck, hawse pipes and ac- commodations were renewed.
