November, 1910 tained on trial being 27% knots, as against a speed of 25 knots said to have been contemplated when the de- Sign was prepated.- In the Italian navy three large battleships, an armor- ed cruiser, and three smaller vessels have Parsons turbines. Spain is build- ing three battleships, three destroyers, and 10 torpedo boats, for which the same type Of engines has been adopt- ed. Denmark, Sweden, Brazil, Argen- tina and China have also made use of the Parsons turbine in recent war ves- sels. Experience on a very large scale in war vessels on actual service has now confirmed the favorable results obtained on the trials of turbine-driven ships. Success in Mercantile Marine. Equally satisfactory results have been obtained in vessels of the mer- cantile marine fitted with Parsons tur-_ bines. The Cunard steamships Lusi- tania and Mauretania have continued to maintain high speed and remark- able regularity of performance in all weathers on their voyages between Liverpool and New York. The Allan liners Victorian and Virginian and the Cunard steamship Carmania also con- tinue to give great satisfaction. The French Trans-Atlantic Co. has adopt- ed Parsons turbines for their new steamship La France, recently launched, for which the speed of 23 knots is contemplated. The Canadian Northern Railway steamships Royal George and Royal Edward (formerly Heliopolis and Cairo) are fitted with engines of the same type, and have performed their service between Bris- tol and Canada with great success. The Japanese steamships Tenyo Maru and Chiyo Maru, propelled by Parsons' turbines, have fully realized the inten- tions of their design on their trans- Pacific service. It has 'been reported recently that orders have been given for a turbine-driven steamship for the service between England and New Zealand, and there is good reason for the belief that the Parsons type of turbine will' be adopted to a much greater extent for oceanic service in vessels of high speed of the mercantile. Marine. In swift vessels of compara- tively moderate dimensions, but great engine 'power, employed in cross-chan- nel and coasting services, or for short voyages, the use of Parsons turbines has been considerable, and recently has been much extended. _In Italy, France and the United States, as well a8 in Great Britain, recent and im- portant examples of this development have occurred, The "combination" system devised by Mr. Parsons, in which low-pres--- Sure turbines are associated with recip- TAE Marine REVIEW rocating engines, is also being de- veloped for mercantile steamships of comparatively moderate speeds, and has given very satisfactory results in working, especially as regards fuel. economy. Amongst the vessels in which this system has been adopced are the great White Star liners Olym- pic and Titanic, now building by Har- land & Wolff, and the Laurentic, built by the same firm. A vessel for the Aberdeen Line, now building at Bel- fast, and an Orient Line steamer, builidng by John Brown & Co., Clyde- bank, are also to have the combina- tion system applied. The New Zeal- and Shipping Co., who first tried that 'system in the Otaki (built by Messrs. Denny), have extended its use to other vessels as a result of experience. The steamer Rochambeau, now building in France, is to be similarly equipped. Cargo Steamer Vespasian. In the last report reference was made to the cargo steamer Vespasian, which had been purchased by the company, and was then being 'fitted with a sys- tem of geared turbines in order to demonstrate the 'possible economy in fuel, weight, and space which that system of machinery would secure, as compared with the best type of recip- rocating engines fitted in cargo steam- 'ers of low speed and great deadweight capacity... During the past year ex- tended trials of the Vespasian have been made, both on the measured mile -and on.ordinary service at sea; thor- ough investigations have also been carried. out to.. determine the actual 'consumption of"stéam and coal. On the. first trials,.made off.the. Tyne, it "was demonstrated that at ordinary sea speeds the geared turbines reduced the steam consumption 15 'per cent as compared 'with the consumption re- quired. .with reciprocating engines. 'Since these results were obtained the -vessel has been. continuously employed on sea sefvice, carrying coals to Rot- terdam, and returning in water ballast. "She has completed 14 voyages, and steamed 8,500° miles in all weathers. The machinery has. worked with en- tire satisfaction, giving no trouble whatever, and there has-been a re- -markable freedom from. racing, even in the roughest weather. The. results 'obtained on the first trials as to the relative economy in steam consump- tion, when. compared with. reciprocat- 'ing engines, have been confirmed by 'the data obtained on -these voyages. 'It may, therefore, 'be. anticipated that the geared-turbine system will. here- 'after find extensive use in the very 'numerous and important' class of cargo steamers of the British and other mer- eae She cantile marine? oy nich ake carrying 451 trade of the world is principally per- formed. Other important applications of the system of geared tutbines are aiso under consideration and experi- roental investigation.
