ABS Extends SafeHull

System To Existing Vessels

American Bureau of Shipping (ABS) chairman Frank Iarossi an- nounced that the class society's

SafeHull™ System has been adapted for use with existing tankers. This application is now available to the marine industry. Later in the year it will be available for use with ex- isting bulk carriers followed by other vessel types. "We were very excited about the development and launching of the

ABS SafeHull System last Septem- ber," Mr. Iarossi said, "as it pro- vided the industry with an innova- tive dynamic-based design and evaluation method for enhancing the structural safety of new tank- ers. But now, we are even more enthusiastic at being able to offer services for applying SafeHull to existing tankers."

The services are called ABS

SafeHull Condition Assessment Ser- vices and will reportedly afford own- ers, operators, charterers, under- writers and others a new risk-man- agement method associated with hull structures. "Through the

SafeHull Condition Assessment Ser- vices, ABS can apply advanced dy- namically-based strength criteria to assess the corrosion and fatigue state of a hull structure. Then, with this technical information, we can iden- tify critical areas and make recom- mendations as appropriate for their enhancement. The result is a better performing, safer hull structure," said Mr. Iarossi. He also pointed out that the new ABS SafeHull Con- dition Assessment Services are avail- able to all existing tankers, not just those under ABS class.

Hitachi Zosen Completes

Superjet-30 Foil-Assisted

Catamaran Dougo

Hitachi Zosen completed the

Dougo, a foil-assisted catamaran in its Superjet-30 series, at its

Kanagawa Works and delivered the vessel to Setonaikai Steamship Co.,

Ltd. (headquartered in Minami-ku,

Hiroshima Prefecture) in Decem- ber 1993. The vessel is commis- sioned in the Hiroshima-Kure-

Matsuyama service, together with theZuiko of Ishizaki Steamship Co.,

Ltd. The high-speed passenger ves- sel is the fourth of the seven

Superjet-30 ships ordered from

Hitachi Zosen last year. Dougo is about 103 feet long with a breadth of 32 feet, depth of 11 feet and draft of six feet. The vessel is able to reach speeds of about 38 knots and can carry 156 passengers. Dougo is equipped with a computerized roll- ing control device in its hydrofoils, with its control effectiveness proven by the excellent cruising perfor- mance of the series. Dougo is a hybrid-type vessel with twin hulls equipped with submerged hydro- foils fore and aft. The weight of the vessel is supported both by the buoy- ancy of the two hulls and the lift of

February, 1994 the two hydrofoils. The features of the vessel also include a wide deck and spacious cabin unique to a twin- hull ship. Furthermore, the high- speed capability and fuel economy of a hydrofoil vessel are attained.

The computerized automatic con- trol of the flaps attached to the hy- drofoils reduces the ship-body mo- tion to about one-eighth of that for an ordinary catamaran, thus ensur- ing greater passenger comfort.

Two diesel engines and two wa- ter jets, manufactured by Niigata

Engineering Co., Ltd., ensure ex- cellent maneuverability and uncompromised passenger comfort by minimizing noise and vibration.

Hitachi Zosen has to date pro- duced more than 50 aluminum hy- drofoil vessels, as well as patrol boats for the Maritime Safety Agency and a number of prefectural govern- ments; super-deluxe motor yachts; and various types of sightseeing vessels.
