The oil collecting ships Bottsand class ( class 738 ), the Bottsand and Eversand are occupied civil folding vessels of the Federal Republic of Germany. They are operated as a shipowner by the German Navy on behalf of the Federal Ministry of Transport and Digital Infrastructure . The ships stationed at the naval bases in Kiel ( Bottsand ) and Wilhelmshaven ( Eversand ) are subordinate to the naval office. The Bottsand was after the turn stationed at the naval base in Warnemünde, but was laid in October 2015 for cost reasons to Kiel.
description
The ships are designed to combat oil spills. For this purpose, they can be opened up to 65 degrees in their central axis from the bow via a joint construction at the stern .
The oil can be pushed together and sucked off in the triangle that is formed as a result and encompasses a catching area of over 40 m². The opening of the triangle is 42 meters.
With a two-millimeter-thick layer of oil and a speed of 1 kn, the ships can hold around 2 × 160 m³ of oil-water mixture per hour. The oil is then separated from the water via a skimming device with the help of separators and pumped into the on-board tanks. The capacity of the ships is 790 m³, which are distributed over six tanks.
The ships of the class were developed and designed by the Lühring shipyard and the Hamburg company Schiffko. The basis of the development was the patent EP0001408 A1 of the Lühring shipyard (publication date April 18, 1979).
Technical specifications
The vessels are of two AEG - electric motors driven, each on two thrusters act. The engines of the Bottsand each 600 kW power that the Eversand each 625 kW. The ships reach a speed of 10 knots .
Both ships have four generators powered by Deutz diesel engines as well as a harbor and emergency generator to generate electricity . The apparent power of the Bottsand generators is 580 kVA each , that of Eversand 700 kVA each. The harbor generators have 135 kVA or 125 kVA apparent power.
The hulls of the ships are reinforced with ice ( ice class "E").
