Wartsila Diesel Introduces

In-Line Version Of Nohab 25 Engine

Deliveries of the Nohab 6R25 en- gines began this past autumn, with the first two engines being installed for propulsion in an Italian cruise yacht, where comfort criteria are particularly stringent.

Besides an advanced resilient mounting system to reduce struc- ture-borne noise and vibration, a special combined exhaust washing/ silencer system has been developed to counter both noise and particu- late emissions.

Hvide, president and chief operat- ing officer of Hvide Shipping Inc.

The Seabulk America is the result of rebuilding the wrecked tanker M/

V Fuji, utilizing the forebody of the former barge 4102. Norfolk Ship- building & Drydock Company (NORSHIPCO), Norfolk, Va., per- formed the joining of the two vessels and below the waterline work, in- cluding the installation of the hi-lift

Willi Becker rudder and Kort noz- zle/propeller. North Florida Ship- yards, Jacksonville, Fla., performed extensive modifications, reflagging, maintenance and repair work on both the Fuji and the forebody. "We are extremely pleased with the Seabulk America and her per- formance capabilities. The Seabulk

America's 24 cargo segregations will make her very marketable and a great asset to the U.S. fleet and our company," said Mr. Hvide.

The unique capabilities of the vessel were demonstrated when she delivered 22,000 tons of phosphoric acid to New Orleans, La., on her maiden voyage. Her six stainless steel center tanks totaling 22,000 cubic meters have the capability of carrying acid and other corrosive cargo with specific gravity of up to 2.1. An additional 161,000 barrels of capacity are available in her 22 inor- ganic zinc-coated wing tanks. She is one of the few chemical tankers in the world which meets the 1990

MARPOL regulations.

The Seabulk America has an overall length of 685 feet, maximum molded beam of 99 feet, and design draft of 36 feet.

Responding to market demand,

Wartsila Diesel has introduced a six-cylinder in-line version of their

Wartsila Nohab 25 engine. Besides general marine applications, the en- gine's weight-power ratio of 7.0 kg/ kw makes it a contender for military and traction purposes. Also envis- aged are high-pressure gas installa- tions.

The Wartsila Nohab 6R25, as the new engine is designated, is a logical complement to the 8-, 12- and 16- cylinder V-engines in the 25 Series, which were introduced on the market in 1986-87. While it is a development of the same basic con- cept, the newcomer embodies many original ideas and is a very modern design offering competitive per-

The Seabulk America is the newest chemical carrier in the U.S. coastwise trade.
