发明名称 An offshore vessel
摘要 In an offshore vessel adapted to be used where extreme weather conditions are expected, the part of the structure coming into direct contact with the sea water is manufactured from concrete, preferably in the form of pre-stressed elements, while the working deck (12) is made as a steel structure. The underwater body includes a four-sided pontoon-frame (10) composed of cube-shaped corner pieces (14) between which tubular boxes (15) extend. The corner pieces (14) carry cylindrical columns (11), upon which, in turn, the working deck (12) rests. Each corner piece (14), plus halves of the adjoining boxes (15) may be assembled in a dry dock and, after being towed out therefrom, can be connected to other similar units. The corner pieces (1a) and box halves may themselves be constructed from prefabricated elements. <IMAGE>
