cylinder, in-line L58/64 four-stroke,
medium-speed engines, with a max-
imum continuous rating of 9,720 kw
at 400 rpm. These alternators sup-
ply power through transformers to
the two 12,000-kw, three-phase syn-
chronous-type propulsion motors,
each directly driving a Lips fixed-
pitch propeller via shafting.
CRYSTAL HARMONY
Cruise Ship
MHI
Built at a cost of $200 million, the
48,621-ton luxury cruise liner Crys-
tal Harmony, constructed by the
Nagasaki shipyard of Mitsubishi
Heavy Industries (MHI), is the first
luxury ship for Los Angeles-based
Crystal Cruises, a subsidiary of Ja-
pan's NYK Line.
Reportedly one of the most spa-
cious ships in her class, the Baha-
mas-registered Crystal Harmony
carries 960 passengers in first class
luxury. Almost all of her passenger
cabins are situated on the outside,
more than half of which have a pri-
vate veranda. She also features one
of the largest penthouses afloat and
the first floating casino to be oper-
ated by Caesars Palace of Las Ve-
gas.
The Crystal Harmony's propul-
sion power is generated by four Mit-
subishi-MAN B&W 8L58/64 large
bore medium-speed diesel alterna-
tor sets. The output is fed via a 6.6
kv main switchboard to two 12 MW
Cycloconverter drives, each serving
its own 11.5 MW synchronous pro-
pulsion motors. ABB Marine sup-
plied and engineered the Cyclo pro-
pulsion drives, generators, switch-
board, bowthruster motors, inte-
grated machinery and auxiliary
automation system.
Plate coolers were installed on the
vessel by Kyoto Machinery Co.,
Ltd., the Japanese division of Alfa-
Laval.
Passenger amenities aboard the
liner include two heated freshwater
pools fitted with movable roofs
called Magrodomes, a special piano
lounge area with foliage on the Lido
Deck, an Italian restaurant and Jap-
anese restaurant.
DIAMOND LADY
Casino/Dinner
Sternwheeler
Atlantic Marine
In March 1991, Atlantic Marine,
Inc., Ft. Georges Island, Fla., will
deliver The Diamond Lady, the first
of three 201-foot sternwheel casino/
dinner vessels for Steamboat Devel-
opment Corporation of Davenport,
Iowa. The vessels' authentic 1890's
design was specially developed by
John W. Gilbert, owner of Boston-
based John W. Gilbert Associates,
Inc.
Interior Design International of
Seattle, Wash., complements Mr.
Gilbert's 1890's theme with its dis-
tinctive Victorian period interiors
design. Gilded Philippine mahoga-
ny, Aubusson-style carpet, carved
Victorian glass panels, sconces,
crystal chandeliers, marble/avonite
counter tops, and embossed ceiling
panels will make The Diamond
Lady one of the most elegant inland
passenger vessels afloat.
Launched in late October 1990,
the 1,200-grt Diamond Lady will
have a waterline length of 170 feet,
width of 46 feet and total light ship
weight of 863 tons.
