with reportedly a three-fold high collision resistance than a single shell tanker. Newbuilding S 236 has a class notation COLL 2 for her wing tanks and COLL 5 for her cen- ter tanks. Other recently delivered double-hull tankers built by Lindenau—Rochen I, Leng and Hummel—have also been awarded similar class notations. The double-hulled Conger is the sister ship of the Wels, which was recently launched by Lindenau Werft. Lindenau Launches Another Double-Hull Tanker For Carl Buttner Shipping The Kiel-Friedrichsort shipyard of German shipbuilder Lindenau Werft recently christened and launched the second 23,400-dwt double-hull tanker of a newly devel- oped design for Bremen shipping company Carl Buttner. The God- mother for the vessel was Mrs. Eva Schmidt. The Wels is the 16th double-hull tanker built and delivered by the yard to international and domestic owners since 1976. At 555 feet in length with a capacity of 27,740 m3, Newbuilding S 236 along with her sister, the Conger, are the largest double-hull tankers sailing under the German flag. She is classed by Germanischer Lloyd + 100 A4 E3, "Chemical Tanker Type lTOil Tanker," MC E3 AUT, INERT. Newbuilding S 236 has the highest collision resistance notation, "COLL," awarded by Germanischer Lloyd. Based on Lindenau's newly de- veloped Tanker Class 2000 design, the vessel has a double side shell WELS Equipment List Main engine MAN B&W Propeller KaMeWa Bowthruster Jastram Generator engine Yanmar Thruster engine ABB Generator AEG Reduction gear Renk Tacke PT0 AE Engine controllers MAN B&W Steering controls Frydenbo Deck machinery Norwinch Shafting KaMeWa Coatings International VHF radio Debeg SSB radio Debe Radar Atlas Elektronik Compass Anschutz Autopilot Anschut Echo sounder Honeywell Cargo pumps Bornemann The Wels has a length between perpendiculars of 524 feet, beam of just over 80 feet, depth of 44 feet and draft of 34 feet. Her MAN B&W 6L 58/64 diesel has an output of 7,440 kw (9,997 hp) and provides a service speed of 15.5 knots. Lindenau reports that the design of the tanker protects the cargo tanks from damage in the case of a colli- sion with low penetration (maximum of 80 cm), such as in a harbor area. Additionally, the shipbuilder also states that, as compared with single- hull vessels, the Tanker Class 2000 design also reduces the amount of spillage in the cases of high depth of penetration accidents because each cargo tank is smaller due to the protective location of the double shell. Inherent in the double-hull de- sign is savings in heating energy due to the insulating air in the side shell. The smooth inner tank walls also save cleaning time and reduce slop. The Wels is expected to be deliv- ered by the end of December 1992.
