The SS Chusan was a British ocean liner and cruise ship, built for the Peninsular and Oriental Steam Navigation Company (P&O)'s Indian and Far East Service in 1950. She was named after Chusan, a small island off China. A smaller version of the SS Himalaya, the Chusan had a gross register tonnage of approximately 24,215; and a capacity of 1,565 passengers and crew. She was built as a replacement for the ship RMS Viceroy of India, lost in the Second World War. She was approximately 646.5 feet (197.1 m) long. The Chusan is said to have brought new standards of shipboard luxury to India and the Far East.
Chusan entered service in 1950, with her maiden voyage from London, England to Bombay, India. But she first made two "shake down" "all first class trips", one of a week's length and the other of a fortnight, sailing to Lisbon, Casablanca and Madeira. For most of her working life, she carried passengers between London, Bombay, Japan, and Sydney, Australia. In 1973, she retired from service and was sold to be scrapped at Chou’s Iron and Steel Company Ltd. in Kaohsiung, Taiwan.
- The Chusan was 646 feet (197 m) long, roughly the same length as two football fields laid end-to-end, and had a beam (breadth) of 85.2 feet (26.0 m).
- Her draft (vertical distance of ship from waterline to keel) was 29 feet (8.8 m). She was powered by twin propellers.
- Two masts, one at the bow and one aft, were present on the Chusan. She had one funnel.
- The Chusan carried eighteen lifeboats, nine on each side.
- Her capacity was 988 passengers and 577 crew, for a total of 1,565 people, though the passenger capacity was changed twice between the two classes (first class and tourist/second class).
Planning and construction (1946-1950) 
Chusan was ordered in May 1946 and was built by Vickers Armstrong Ltd., Barrow (yard number #964) in the port of Furness, England. In February 1947, her keel was laid, and was launched on 28 June 1949 and christened by the wife of Viscount Bruce of Melbourne, Viscountess Bruce. In June 1950, she underwent sea trials, and was delivered to P&O on 14 June 1950. The Chusan was the largest and last ship built for the Far East Services of P&O. A notable feature of the ship is that it was the first passenger ship to be equipped with anti-roll stabilizers.
Four transatlantic crossings were scheduled for Chusan under the charter of the Cunard Line. However, a delay occurred, and therefore her first voyage was to Rotterdam for the purpose of carrying British officials to a freight conference. The four transatlantic voyages were provided by the Stratheden.
Ownership by the P&O (1950-1970) 
The Chusan's maiden voyage was a nine-day cruise from Southampton to Madeira and Lisbon beginning on 1 July 1950. On 15 September 1950 she then made a voyage from London to Bombay via the Suez Canal. The service for which Chusan was intended commenced on 7 November 1950, from London to Hong Kong. After this, she would continue to the Far East, along with the ships SS Corfu, SS Carthage, and SS Canton. In November 1950, Chusan resumed P&O's service to Japan, and made the first call after World War 2 at Yokohama.
Chusan was fitted with a Thornycroft funnel in May 1952. This was done to reduce the presence of soot. The job was done by R&H Green and Silley Weir Ltd. at London.
On 12 June 1953, Chusan accidentally collided with the freighter Prospector, off the Goodwin Sands in the English Channel. The collision tore an 26-foot (7.9 m) breach in her hull, but did not sink her. Resultantly, she was sent back to London for two days of repairs. In April 1954, Chusan departed London for a world cruise lasting 92 days, which was a first of the P&O Line.
In March 1955, another incident occurred, which involved bringing a smallpox-infected passenger to Port Said, Egypt. A bomb hoax during a Mediterranean cruise occurred on 2 September 1955, and the ship returned to Naples to be searched.
Passenger capacity was changed to 464 in first class and 541 in tourist (second) class in the year 1959. Chusan was refitted from December 1959 throughout March 1960, which involved the installation of air conditioning throughout the ship. She was transferred to P&O-Orient Lines in May 1960. Chusan was taken off Far East passenger service and began to make cruises, before being again transferred to a regular service from Australia to Yokohama, with an intermediate port of call at Hong Kong.
In October 1966, she was again transferred back to P&O Lines. Passenger capacity was again changed to 455 in first class and 517 in tourist class.
Final Years (1970-1973) 
The P&O's association with India ended in January 1970, with a voyage by Chusan on the final London to India service route. While docked in Southampton in July of that year, a fire occurred in her funnel uptakes. She was transferred to the P&O Passenger Division in 1971, and from December of that year to January 1972, she operated on P&O's first cruises starting from Cape Town, Africa.
Her final commercial voyage ended on 26 March 1973, in which she arrived in Southampton. She retired from service soon after and was sold to Mitsui & Co.. In turn, Chusan was sold to Chou's Iron and Steel Company Ltd. in Kaohsiung, Taiwan, for scrapping. She arrived there on 1 July 1973, after a life of 23 years. Demolition of Chusan at the scrapyard began in September 1973.
