SS Aberdeen (1881)
[2]: 106–111 Aberdeen was fitted with two double ended Scotch type steel boilers, running at 125 pounds per square inch (860 kPa).This level of efficiency meant that steamships could now operate as the primary method of maritime transport in the vast majority of commercial situations.This was reliant on boilers made of steel manufactured to a sufficiently consistent standard, designed on the best engineering principles and operated with appropriate care.[b] Despite the strict rules on this laid down by the Board of Trade, there were occasional failures (with severe consequences for anyone in the boiler room at the time).The outward leg started from London, picked up passengers at Plymouth, made a coaling stop at Cape Town and arrived at Melbourne on 14 May, having logged 44 days of steaming.She averaged 302 nautical miles (559 km; 348 mi) per day at a daily fuel consumption of 35 tons – well within the "in service" figure estimated from trials.The third leg of the triangle was tea from Foochow (Fuzhou), back to London via the Suez Canal, with intermediate stops at Hong Kong and Singapore.However, they were slow to adapt a ship for its carriage, preferring to wait for the cessation of any market resistance to this product that might affect the return on the investment required.[8] In May 1915, the Royal Navy submarine HMS E11, towards the end of her first cruise into the Bosphorus, was unable to attack the passing Halep, as all E11's torpedoes had already been fired.[11] On 25 August 2022, a rally and a dive on the shipwreck took place, to commemorate and pay tribute to the soldiers and medical personnel who died during the incident.
