December, 1909 "TAE Marine REVIEW 923 New Ortent LINER ORVIETO. Another New Orient Liner ESSRS. Workman, Clark er Co. .of: Belfast. have "just completed the tw:n-screw steamer. Orvieto, the sec- ond of the new orient liners built by them to the order of the Orient Steam Navigation "Co,, Litd., to carry on the new Australian government mail service to Britain which comes inito force on. Feb, 1, next. This ves- sel, the Orvieto, is a sister ship to the Otranto, completed by the same fin in Jhly last: "In, addition © to these two vessels there were also built on the Clyde three vessels of similar design also for the same ser- vice. The general dimens ons of these ships vary very little, those of the Belfast built ships being as un- der: Length over all, 552 ft.; length between perpendiculars, 535 ft.; ex- treme breadth, 63 ft. 10%4 in.; depth from shelter deck, 42 ft.; gross ton- nage, 12,124 tons; mean measurement displacement, 15,250 tons; mean sef- vice draught, 24 ft. 6 in.; total cargo capacity, 257,880 cu. ft.; and dead- weight capacity, 6,100 tons. They have accommodation for 235 first class, 195 second class, and 666 third class passengers. For the saloon passengers there is provided a large and luxurious lounge, and an exceed- ingly handsome drawing room. The third class passenger accommodation is of a character undreamed of but a few years back. These passengers will enjoy the privacy of separate cabins, many of wh'ch contain only two berths, and they also have ex- cellent dining saloons, music rooms and smoking rooms. It may be mentioned here that' the voyage is to be shortened after January next by two days under the new contract which the Australian government has made with the Orient line. Propelling Machinery. The propelling machinery was de- sgned for all of the ships to give a speed of 18 knots, with a mean ser- vice displacement of 15,000 tons, and to run for 24 hours at not less than 1634 knots with a coal consumption not exceeding 1.4 lbs. per horse- power-hour. The high pressure cyl- inder is 2834 in, in diameter; the first intermediate, 41 in.; the second in- termediate, 58% in.; and the low pres- sure 84 in.; the stroke in all cases being 60 in. Each cylinder is fitted with a hard, close-grained cast iron liner, form- ing, withthe otter case, a steam jacket. The cylinders and working patts dre arranged on. the Yarrow- Schlick-Tweedy system of balancing, with the high-pressure and low-pres- sure cylinder forming the first cou- ple, and the second intermediate and first intermediate the other couple, the valves being on the outside of each pair. These valves are: of the piston type for the high-pressure and first intermediate cylinders, and of the double-ported slide type for the sec- ond intermediate and low-pressure cylinders. There are no auxiliary en-. gines worked from the main engine, and the condenser is in all cases en- tirely separate. The construction of the columns may be noted. These are spread so as to give greater rigid- ity and permit easier access. The main bearings are extra long, and
