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. (continued)
