Offshore-plattform for boring etter eller produksjon av hydrokarboner |
摘要 |
Platform for drilling after or production of hydrocarbons at sea, consisting of a semi-submersible platform body which supports drilling and/or production equipment on its upper surface. The platform body is designed as a vertical mainly flat bottomed cylinder which is provided with at least one peripheral circular cut-out in the lower section of the cylinder since the centre of buoyancy for the submerged section of the platform is positioned lower than the centre of gravity of the platform. |
