Diamond Princess is a cruise ship owned and operated by Princess Cruises. She began operation in March 2004 and primarily cruises in Asia during the summer and Australia in the winter season, she is a subclassed Grand Class ship, which is also known as a Gem Class ship. Diamond Princess and her sister ship, Sapphire Princess, are the widest subclass of Grand-class ships, as they have a 37.5 m (123 ft) beam while all other Grand Class ships have a beam of 36 m (118 ft). Diamond Princess and Sapphire Princess were both built in Nagasaki, Japan by Mitsubishi Heavy Industries.


The ship was originally intended to be christened Sapphire Princess. However, construction of the ship originally intended to be named Diamond Princess (presently sailing as Sapphire Princess) was delayed when fire swept through her decks during construction; because completion of the now-damaged ship would be delayed for some time, her sister ship, which was also under construction, was renamed to Diamond Princess. The name swap helped to keep the delivery date of Diamond Princess on time,[3] she was the first Princess Cruises ship to be built in a Japanese shipyard and lacks the "wing" or "spoiler" across the rear which can be seen on Caribbean Princess.


The diesel-electric plant of Diamond Princess has four diesel generators and a gas turbine generator; the diesel generators are Wärtsilä 46 series common rail engines, two straight 9-cylinder configuration (9L46), and two straight 8-cylinder configuration (8L46). The 8- and 9-cylinder engines can produce approximately 8,500 kW (11,400 hp) and 9,500 kW (12,700 hp) of power respectively; these engines are fueled with heavy fuel oil (HFO or bunker c) and marine gas oil (MGO) depending on the local regulations regarding emissions, as MGO produces much lower emissions but is much more expensive. The gas turbine generator is a General Electric LM2500, producing a peak of 25,000 kW (34,000 hp) of power fueled by MGO; this generator is much more expensive to run than the diesel generators, and is used mostly in areas, such as Alaska, where the emissions regulations are strict. It is also used when high speed is required to make it to a port in a shorter time period. There are two propulsion electric motors which drive fixed-pitch propellers and six thrusters used during maneuvering; three bow and three stern; the propulsion electric motors (PEMs), are conventional synchronous motors made by Alstom Motors. The two motors are each rated to 20 MW and have a maximum speed of 154 rpm. (Rated speed of 0-145 rpm.)

In June 2017 Diamond Princess was retrofitted with a hull air lubrication system to reduce fuel consumption and related CO2 emissions.[4]

Cruising areas[edit]

Prior to 2014, Diamond Princess alternated sailing north and southbound voyages of the glacier cruises during the northern summer months and in the southern summer, she sailed from Australia and New Zealand. Starting in 2014, she undertook cruises from Yokohama for Tokyo or Kobe in the northern summer season.[5]

For the 2016-17 season, she sailed roundtrip cruises in the northern winter months from Singapore.[6] Kota Kinabalu was added as part of its destination along with Vietnamese port of Nha Trang in December 2016,[7] she resumed voyaging from Sydney for the 2017-18 season.[8]

After the 2018 Australia & New Zealand cruises, Diamond Princess was repositioned into South-East Asia for most of 2018, varying between Japan, South Korea, Singapore, Vietnam, Taiwan and Malaysia,[9] it is projected to remain in South-East Asia (predominantly in Japanese waters) to early 2021.[10]
