Lindenau Delivers

Largest Double-Hull Tanker

Under German Flag

The 23,400-dwt Dorsch, one of two large double-hull tankers flying the German flag for Carl Buttner &

Co, Bremen.

German shipbuilder Lindenau

GmbH Schiffswerft & Maschin- enfabrik of Kiel-Friedrichsort, re- cently delivered the 23,400-dwt

Dorsch, which along with her sister, the Conger, are the largest double- hull tankers under the German flag.

Delivered to Partenreederei

Dorsch c/o Carl Buttner GmbH &

Co., the Dorsch is designed for the transportation of chemicals up to

IMO type I product oils and crude oil.

Main propulsion for the Dorsch is supplied by a MAN B&W Diesel power plant, a model 6L 58/64 main engine, rated at 9,977 hp at 400 rpm, with Renk-Tacke reduction gearing and four-blade variable pitch propeller.

The 557-foot Dorsch has a beam of 81 feet, draft of 34 feet and gross tonnage of 12,299.

The M/T Dorsch was constructed under the class and supervision of

Germanischer Lloyd and has re- ceived the class notation GL +100

A4 E3 "Chemical Tanker Type I" "Oil Tanker" COLL 5 (Center Tanks)

COLL 2 (Wing Tanks) + MC E3

AUT. Inert.

The ship's hull lines were devel- oped for an optimized speed/power characteristic and good seakeeping properties. Her speed during sea trials was 15.5 knots at an engine output of 8,850 hp.

Constructed with a double bot- tom and double side shell for envi- ronmental safety, the Dorsch and her sister, the Conger, were the first

German tankers to have received the IMO Class 1 chemicals for their center tanks and IMOClass2 chemi- cals for wing tanks by Germanischer

Lloyd. Furthermore, the class nota- tions "COLL 5" for the center tanks and "COLL 2" for the wing tanks indicates that the collision protec- tion of the wing tanks is three times and collision protection of the outer tanks is 10 times better than the single shell of a conventional oil tanker.

The Dorsch also fulfills all

MARPOL rules including Annexes

I-V. She has protective location of 1 EC CC CG I a

Because of her double-hull de- sign, the Dorsch has smooth inner tank walls, allowing for more effi- cient and faster tank cleaning, saves heating energy, and completely sepa- rates cargo and ballast water.
