Diamond Princess Makes Maiden Voyage (April 7, 2004)
The Diamond Princess, one of the
largest passenger liners in the world with a gross weight of 116,000 tons, set
out on its maiden voyage from Los Angeles to Mexico and back on March 13 after
being completed by Mitsubishi Heavy Industries, Ltd., at the Nagasaki Shipyard
and handed over to its owner, P&O Princess Cruises.

Different from Existing Passenger Ships
The Diamond Princess differs from existing passenger
ships, first of all, in the fact that when cruising it uses a diesel engine and
when moving at high speed it employs a CODAG-configuration power system, which
combines the diesel engine and a gas turbine. While providing strong output, the
gas turbine, which utilizes airplane technology, produces little noise and little
vibration. Though rooms right above the propeller would normally be quite noisy
and subject to vibration, it would be possible to put luxury suites in this location
on the Diamond Princess. At the same time, the positioning
of the gas turbine behind the funnel gives the ship more inner space.
Mitsubishi Heavy Industries developed the design for the ship through repeated
research in its water tank experiment laboratory. For example, in order to prevent
the smell of exhaust gas from the funnel and sewage tanks from reaching the open
deck or cabin balconies, the company carried out wind tunnel tests repeatedly
for about half a year before deciding on the shape of the funnel surroundings
and the distribution of exhaust pipes.
State-of-the-Art Environmental Technology
As environmental technology, meanwhile, the Diamond
Princess uses the world's first low-exhaust diesel engine, along with a
smoke-extraction apparatus for garbage incineration and a sewage processing apparatus
developed from next-generation biotechnology. Through the utilization of garbage
for power generation, the secondary use of processed waste water, and so on, the
ship processes all of the large amount of waste produced during a voyage on board
and discards absolutely nothing into the ocean. In addition, when anchored in
port, the Diamond Princess receives power supply from
land instead of its own engines, thereby reducing exhaust to zero at such times.
The Diamond Princess measures 290 meters in length
and 37.5 meters in width and rises 54 meters above water level, the height of
an 18-story building. The ship has 1,339 cabins for 2,670 passengers (calculated
as two persons per cabin) and a crew of about 1,200. The magnificent facilities
on board include a dance hall, three show lounges, five swimming pools, a miniature
golf course, a tennis court, three main dining rooms, and two subrestaurants.
