Offshore drilling and prodn. platform - with floatable part resting through deformable layer on anchor part (NL 29.3.78)

摘要

An offshore platform for oil drilling and prodn. consists of an upper floating part with ballast tanks, and a lower anchor part which rests on the sea floor. The bottom of the upper part rests with supporting areas on parallel supporting areas of the lower part. A deformable layer between both areas ensures a uniform distribution of the contact pressure. This eliminates the effect of wave and wind pressure on the legs, normally needed to support a platform deck above sea level.
