New Double-Hull Tanker Design

Developed By Lindenau

To Meet MARPOL, OPA Rules

Drawing of a 17,000-dwt version of Lindenau's new Tanker 2000 Class design.

Kiel-based German shipbuilder

Lindenau Werft has completed the development of a new double-hull tanker class to meet the provisions of both the recently adopted

MARPOL regulation 13F and the

Oil Pollution Act of 1990 (OPA 90).

Called the Lindenau Tanker Class 2000, the design is based on the experience the yard has gained from the construction of 38 tankers, rang- ing in size up to 25,000 dwt. The yard designed and built its first double-hull tanker over 16 years ago in 1976. Since then, Lindenau has delivered 15 double-hulled tankers to international customers.

Approved construction plans have already been granted to the

Lindenau Tanker Class 2000 by the classification societies of Lloyd's

Register of Shipping, Det norske

Veritas, Germanischer Lloyd,

American Bureau of Shipping, and

Bureau Veritas.

The Tanker Class 2000 design is offered in capacities between 1,500 dwt and 30,000 dwt in over 100 variations.

The ship has a double bottom with 300 - mm deadrise and a 1,350 - mm wide double side in transverse framing system with extra interme- diate frames in the ice belt. The special double-hulled construction is designed "surveyor friendly" and offers increased collision resistance in the cargo tank area compared to single hull vessels. This translates into reduced risk of pollution after accidents at sea. Additionally, the insulating layer of air in the double hull also saves on cargo tank heat- ing.

Extensive use of both remote con- trol and management systems also contribute to safe and low-cost op- eration. Some of the systems in- clude: remote controlled cargo and ballast valves; a tank radar content measurement system for all cargo tanks; a pneumatic content display for all ballast, fuel oil storage and drinking water tanks; a cargo tank temperature measurement system, as well as a draft measurement sys- tem on-line to the load control com- puter.

The engines are fitted with a cen- tral alarm and control system and there is remote control of the fuel oil and sea valves.

In Scandinavia, for example, these systems enable the ship to be operated by a crew of 11.

Exhaust gas energy is reused for ship operation (600 kW gas boiler), while 1,500-kva shaft generator is used for on-board electricity.

The main engine is a four-stroke new generation Krupp MaK6M601, with an output of 6,600 kW (8,850 bhp) at 500 rpm. This engine can be operated with low-cost heavy fuel oil IF 380. To power the cargo pumps, the shipyard has selected three Cat- erpillar diesels, each producing 845 kva at 1,800 rpm, and an additional 135-kva diesel generator for emer- gency power.

To provide optimal maneuverabil- ity, the ship has a Willi Becker rud- der and, a Schottel pump jet, with an output of 1,000 kW.
