IDEMITSU MARU

Ishikawajima-Harima

The 258,090-dwt, super-energy- saving very large crude carrier

Idemitsu Maru was delivered re- cently by Ishikawajima-Harima

Heavy Industries Company's Kure

Shipyard to Idemitsu Tanker Com- pany of Tokyo.

The big tanker has an overall length of 1,058 feet, beam of 196.85 feet, depth of 94.5 feet, and maxi- mum draft of about 63 feet. Propul- sion is provided by a low-speed IHI/

Sulzer 8RTA84 diesel engine with a maximum continuous rating of 23,500 bhp at 65 rpm and normal rating of 21,150 bhp at 62.5 rpm. On

The Siemens propulsion control system, which includes automatic main engine overload control as well as an engine load increase feature, incorporates different operating modes, including: constant-speed operating mode at 136 rpm for shaft alternator operation; and two com- bination operating modes—one thrust mode and one pitch mode— where the engine speed, propeller thrust, and propeller pitch are con- trolled according to a pre-estab- lished curve.

At sea, the ship will normally operate in the constant-speed mode at 136 rpm, and the shaft-driven alternators will feed the main switchboard. As it is not the inten- tion to run the two shaft alternators in parallel, the main switchboard is capable of being operated in a "split" mode by means of a section breaker on the bus bar. In this mode each alternator will feed half of the main switchboard.

The vessel's hull form has been developed to give good propulsion and seakeeping performance with due regard to the large propeller tip clearance requirements at the vari- ous design conditions. The lines have been designed to give the smallest possible resistance, with the bulbous bow designed for a draft of 24.6 feet and optimized for a ser- vice speed of 19.5 knots.

Except for certain parts of the public spaces, where special features are introduced, Dampa continuous ceiling systems consisting of pre- stressed, baked enamel, steel/alumi- num panels, are used throughout the accommodations. Sound-ab- sorbing decks consisting of mineral wool slabs with steel tops are in- stalled in the crew accommodations above the engine rooms as well as below the bandstand and dance

The Holiday is a typical example of the ships produced by the Ship

Division of Aalborg Vaerft—a high- ly complex passenger vessel of the most advanced design and compris- ing the latest technology, purpose- built to insure full compatability with the requirements of the own- er.

The Sparrows Point Yard, one of the nation's foremost construction yards, is now ready to repair and maintain your ship—everything from a survey, rebuilding collision damage, to a major conversion.

A new intermediate gate gives the yard's modern basin the flexibility needed for repair work. This gate can be installed at one of two positions, so that the gigantic 200-ft. x 1,200-ft. basin can be divided into sections measuring 300 and 900 ft. long, or 685 and 515 ft. long.

All the yard's world-class fabricating and shop facilities, as well as the skilled trades and crafts people, are ready to work on your ship.
