RMS ''Mooltan'' was an ocean liner and Royal Mail Ship of the Peninsular and Oriental Steam Navigation Company (P&O). She was ordered in 1918 and completed in 1923. She served in the Second World War first as the armed merchant cruiser HMS ''Mooltan'' (F75) and then as a troop ship. She was retired from P&O service in 1953 and scrapped in 1954. ''Mooltan'' was unusual in combining both quadruple-expansion steam engines and turbo-electric transmission. When completed in 1923 she had only her quadruple-expansion engines, but in 1929 turbo generators and electric propulsion motors were added alongside them to increase her speed. ==Building== P&O ordered ''Mooltan'' and her sister from Harland and Wolff Ltd on 29 November 1918. ''Mooltan'' was given yard number 587.〔 She was launched on 15 January 1923, completed on 22 September 1923,〔 undertook sea trials and was handed over to her owners on 21 September 1923. She was named ''Mooltan'' after the city of Multan in the Punjab, and also after an earlier that was lost to enemy action in 1917. The new ''Mooltan'' was the first P&O ship to exceed 20,000 tons. She had 56 corrugated furnaces heating six double-ended and two single-ended boilers that had a combined heating surface of .〔 These supplied steam at 215 lbf/in2 to her two four-cylinder inverted direct acting quadruple-expansion steam engines.〔 ''Mooltan'' had broad decks and gained a reputation for great steadiness, but her speed was sacrificed for reliability and comfort. She had a small rudder that impaired handling. She had two funnels, but the second was a dummy that served as an engine room ventilator rather than a smokestack. ''Mooltan'' was finished in P&O's traditional colours: her hull black with a white band, her boot topping red, her upper works and lifeboats buff, her large vents black, her small vents buff and her two funnels black. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RMS Mooltan」の詳細全文を読む スポンサード リンク
