Nagasaki Shipyard & Machinery Works, Mitsuhishi Heavy Industries: Diamond Princess and Sapphire Princess
History of the Nagasaki Shipyard and Machinery Works
Nagasaki Shipyard & Machinery Works, owned by Mitsubishi Heavy Industries (MHI), is a shipyard established in 1857 as the first factory dedicated to ship maintenance and repair in Japan. At first, the site was operated by the Japanese government, before being sold to MHI in 1887. Since then, this privately owned shipyard has gone on to manufacture a significant volume of the ships produced in Japan.
Today, the shipyard is operated by the MHI’s Shipbuilding and Ocean Development division. The technical expertise built up at the shipyard over more than a century is put to use in the manufacturing of liquefied natural gas (LNG) carriers, liquefied petroleum gas (LPG) carriers, and container carriers, which support global logistics. The shipyard also manufactures passenger ships, including large-scale, luxurious cruise ships and high-speed passenger ferries.
The shipyard is also utilized for the manufacturing of machinery and equipment for marine exploration, observation, and development, contributing to global fisheries and deepwater offshore fossil fuel drilling activities, as well as to marine science. MHI, via its Shipbuilding and Ocean Development business, is also active in a number of marine-related fields of increasing value and interest to our modern society, including the expansion of port facilities, the exploitation of marine resources, and the prevention of ocean pollution. It has also built specialist research equipment such as manned research submersibles, deep-sea exploration equipment, and the deep sea drilling vessel CHIKYU.
Here, we introduce two cruise ships manufactured at the Nagasaki Shipyard & Machinery Works: Diamond Princess and Sapphire Princess.
Diamond Princess, owned and operated by UK’s P&O Cruises, was built at Nagasaki Shipyard & Machinery Works in 2004. It is a luxury liner with 1,339 passenger rooms aimed at the global high net worth market. Of these 1,339 rooms, 72% have an ocean view and 56% have private balconies. This ship has seven restaurants, some of which are open 24 hours, so that passengers can enjoy meals as they wish on the ship. It is fully equipped with gas turbines and the most-advanced drainage treatment systems. Full control of emission and drainage is ensured, meeting even the strictest of environmental regulations, currently present in Alaskan waters.
Sapphire Princess, also owned and operated by P&O Cruises, was built as a sister ship of Diamond Princess. An interesting history exists behind the reason the two were built as sister ships. In 2002, a fire broke out on ‘Diamond Princess,’ which was under construction at the Nagasaki Shipyard & Machinery Works, and the ship was damaged. In order to meet the deadline of the delivery to P&O Cruises, MHI swiftly remodeled ‘Sapphire Princess,’ which was under construction around the same time, and then delivered the remodeled ‘Sapphire Princess’ as Diamond Princess to P&O Cruises. The damaged former ‘Diamond Princess’ was later repaired and rebuilt, and finally completed as Sapphire Princess.
