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. 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.
Ports of call
Prior to 2014, Diamond Princess alternated sailing north and southbound voyages of the glacier cruises during the northern summer months. In the southern summer, she sails from Australia and New Zealand, and cruises around Asia. Since 2014, she sails Japan cruises from Yokohama for Tokyo or Kobe in the northern summer season.
For the 2016-17 season, she will sail roundtrip sailings in the northern winter months from Singapore replacing the Sapphire Princess. Kota Kinabalu was added as part of its destination along with Vietnamese port of Nha Trang in December 2016. Her Australia & New Zealand voyages from Sydney will be replaced by the Emerald Princess, but will resume these voyages for the 2017-18 season.
After the 2018 Australia & New Zealand cruises, the Diamond Princess has been repositioned into South-East Asia for most of 2018, varying between Japan, South Korea, Singapore, Vietnam, Taiwan and Malaysia. Her 2018-2019 Australia & New Zealand voyages have been replaced in favour of Majestic Princess which arrived in Sydney on September 15th. Thus, Diamond Princess is most likely to stay in South-East Asia for the Christmas & New Year's Season and into 2019.
In February 2016, Diamond Princess experienced a gastroenteritis ("gastro") outbreak caused by norovirus sickening 158 passengers and crew on board, as confirmed after arrival in Sydney by NSW Health.
