Abstract

A ship according to the invention for conveying and setting up offshore structures having:a hull with a U-shaped cross-section having an open stern and projections of the side walls extending at the rear beyond the rear edge of the floor,jack-up leg systems with jack-up legs integrated in the hull that are movable in a vertical direction with their bottom ends in positions below the floor, anda crane that can move on the top edges of the side walls.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]The invention relates to a ship and a method for conveying and setting up offshore structures. The ship and the method are especially intended for conveying and setting up offshore wind turbines.[0004]Operating wind turbines on the sea promises a high energy yield due to high average wind speed. Consequently, more offshore wind turbines should be set up. In the North Sea, several large areas have been designated for setting up wind turbines. These are generally located outside of the 12-mile zone. The depth of water is 10 meters to a few multiples of 10. It frequently ranges from 40 to 50 m.[0005]When setting up the offshore wind farm Alpha-Ventus, wind turbines were set up using the Thialf platform by the Dutch company Heerema. This is a very large piece of equipment that is typically used to set up oil platforms. The piec...
