Italians Improve the Motorship Ansaldo San Giorgio I, First of Fleet of Suc- cessful Carriers, Now in New York C DONNELL & TRUDA, New York, agents for the Tran At- lantica Italiana, have placed in the New York service some motor ships of improved design. These vessels were built by the Gio. Ansaldo & Co., ship- builders and. engineers at Muggiana, Spezia, and Turin, Italy. The first of the vessels to arrive in New York was the AnsALpDo SAN Grorcro I. There are two sister ships bearing the same name but numbered II and III. The AnsaLpo San Grorcio I started on her return trip on Sept. 16. At that time she had been in service 18 months and had given excellent results. The bunker requirements are extremely small and her fuel consumption is said to be unusually economical. This ves- sel, when first completed, left Genoa and went to Glasgow and returned. She then sailed from Genoa for Valparaiso and returned, after which she was put in the New York run. So excellent have been the results obtained from this vessei that the Italian line is building several similar boats in which are incor- porated various improvements. The engine room on the ANSALDO San Giorcio I is unusually commodious. Fuel is carried in tanks abreast the en- gines. Auxiliary engines' are placed on deck in a specially constructed house, the smoke stacks being utilized by these auxiliaries. On the new motor ships to be built for this line the auxiliaries will be electrically operated. The in- creased use of electrical appliances aboard these ships results not only on account of the speed that can be ob- tained, but because this equipment en- ables steamship companies to employ 'stroke being 35.45 inches. fewer men in operating their vessels. The Ansatno San Giorcio I measures 393 feet 1 inch in length over all, is 51 feet 6 inches molded breadth, 30 feet 2 inches molded depth, and has a loaded draft of 24 feet 7 inches. She measures 8100 tons deadweight, 5663 tons gross registered, or 3485 net tons. The vessel is driven by two sets of 2-cycle diesel engines, placed aft. She makes a speed of 11 knots. The boat has the highest class of the British Corp. register and of the Registro Navale Italiano. The cargo holds are designed to be free of obstructions, thus permitting better and quicker cargo handling. This was ade- quately demonstrated when she un- loaded her miscellaneous cargo at the port of New York. : Chief interest in this ship lies in her diesel propelling machinery. This con- sists of two diesel engines of the 2- cycle, single acting type, each having four cylinders and four cranks. They develop 1100 shaft horsepower at 100 revolutions per minute. The cylinders measure 24.75 inches in diameter, the The maxi- mum pressure is about 450 pounds per square inch, and the fuel consumption of heavy oil not more than 0.43 pounds per brake horsepower. The ship can carry sufficient fuel in her bunkers to drive her fully laden at a speed of about 11 knots per hour for a distance of 7175 nautical miles. Furthermore, it is said, these engines can run on a heavy tuel oil of 16 Baume. The auxiliary machinery, composed of a 3-stage air compressor, scavenging pumps, water circulating and_ bilge pumps, is driven from the forward con- MOTOLSHIP ANSALDO SAN GIORGIO I Italians embody many improvements in this new commerce carrier driven by internal combustion engines 563 Trade tinuation of the crankshaft. A complete set of pressure gages and controlling levers for the operation of the main and auxiliary machinery for starting and reversing the engine is arranged on a central control platform. The engine room auxiliaries consist of ballast pump, lubricating oil pumps, sanitary pumps, deck pumps, and fuel oil pres- sure pumps. -- While in port, all of the auxiliary pumps are driven by steam supplied by two oil-fired vertical boilers, which are housed on the upper deck above the after end of the engine room, These boilers are 8 feet in diameter by 19 feet 6 inches high, having a working 'pressure of 100 pounds per square inch While at sea, it is not necessary to fire the auxikary boilers, the auxiliary pumps then being driven by compressed air furnished by the main engines. The location of this machinery gives an ex- ceptionally light; airy, and spacious engine room. Deck machinery is steam driven and is so designed and installed that cargo can be handled: at a low cost. The cargo hatches, which are four in number, are unusually large and, therefore, the larg- est boxes or parts of machinery can be handled with the least possible delay. The Transatlantica Italiana, which is improving its American freight serv- ices by placing these motor ships in the New York run, also conducts the well known passenger service between New York and Naples and Genoa. This >is. the. line =~ thar Goes ates the passenger steamers GIUSEPPE VerpiI and Dante AvicHisri. The line also operates the Henry R. Ma tory.
