J number there were the regular crew operators and several representatives of the shipping board engaged ~ in making tests. Notwithstanding all this number of men it was easy at all times to get about, and the ship- shape arrangement and condition of equipment was the subject of much comment. Like the other vessels, the SEMINOLE was completely stripped before start- ing the work of installing the new power plant. The arrangement of machinery was carefully designed to fit the individual character of the SEMINOLE’S equipment, which in some respects differs from the previous vessels. 28 From the 80-day continuous test of the main engine at the plant at Hamilton, O., the positions of the throttle and the corresponding brake horsepower were known and_ this helped in determining actual perform- ance of the engine at sea. All of the auxiliaries below and above decks are electrically driven. The details of this equipment are shown in accompanying tables. The original windlass, built integrally with a small steam engine, was re- built, in place, for electric motor drive. To do this the bracket and bed plates supporting the steam en- gine were merely cut off with a gas torch and a new bed plate containing MARINE REVIEW—December, 1927 a 25-horsepower Westinghouse motor was bolted on. The steering gear is operated from the bridge by a special gyro pilot and dual electric steering system developed by the Sperry Gyro- scope Co. The method of steering may be quickly changed from hand operation to automatic or vice versa. The cargo winches are all new and of the special design worked out by the Lidgerwood Mfg. Co., in co-operation with shipping board engineers. Before installing the new machinery the SEMINOLE was drydocked, scaled, chipped and painted. The hull is of modern design built on the Isher- wood system of framing. The trial trip, although held under the direction of the shipping board, represented by Chairman T. V. O’Con- nor, Commissioner P. S. Teller, Cap- tain R. D. Gatewood and _ others, was actually carried on by the ship’s regular force of commissioned officers, headed by Herbert Hudson, captain. Done In New York Yard An accompanying illustration gives a general view of the Tietjen & Lang plant of the Todd Shipyards Corp. where the SEMINOLE was converted to diesel power. This is the first New York shipyard to secure one of the conversion contracts. It did so in the case of the SEMINOLE on the low bid installation and alterations of $436,260. Following her trials the SEMINOLE proceeded to pier 4, army base, Brook- lyn, where she at once started load- ing cargo for Australia. The vessel has been allocated to the Roosevelt line for the Australian, Far East and India service. She is now classed with the finest American freighters afloat. The officers of the SEMINOLE are: Captain, Herbert Hudson; chief engi- neer, T. M. McComb; first officer, GC, V. Kane; second officer, FP. H. Erickson; third officer, J. M. Al- brecht; steward, A. F. Tarte; first engineer, A. L. Foster; second engi- neer, F. Roberts; third engineer, W. F. Wylie; fourth engineer, A. C. Cartwright; electrician, W. Stanton. Thus remains of the original 12 vessels in the board’s first conversion program only two which have not had sea trials, the WEST GRAMA and the Winuscox. The WEST GRAMA’S trial was scheduled originally for mid-November and it is at the time of this writing, to be held Dec. 2. The WILLSCOX’s engine of double acting M. A. N. type built by New London Ship and Engine Co., com- pleted its 30-day shop test successfully July 17, and is being installed. isa Ni Tapa oneal
