Abstract

Improvements related to self-elevating marine platforms, adapted for drilling and production of oil wells and including a main hull built to carry loads, machinery and cabins on top of a body of water in an offshore well, characterized by the fact that the set of platform comprises: a number of horizontally spaced spaced auxiliary helmets, each auxiliary helmet is fully arranged sufficiently outside and welded to the main helmet; each auxiliary hull has cross sectional dimensions large enough to define a vertically extending well, and a large volume water-tight tank around the well, each tank may be flooded with water or empty; Each well contains an elevator adapted to movably receive there a leg that extends vertically to the ocean floor, whereby the platform can vertically ascend or descend on the legs; and all tanks, when flooded, in all auxiliary hulls have a combined volume that is adequate to provide the required pre-load for the platform when the platform is raised above the body of water.
