Abstract
A mobile offshore platform and method of fabrication are disclosed. The platform features a deck member, a base member, leg structures interconnecting the two members, and means for varying the distance between the members. The leg structures are secured to the base and are preferably spaced around the periphery of the work area at the vertices of a regular polygon to provide a deck member having a large, substantially obstruction-free, work area. The legs are also connected to the base member to provide a force resistant to vertical flexing of the base member, and to distribute more uniformly the loading of the base member. The base member is adapted to store petroleum products. A multi-tiered embodiment for deep water work is also disclosed.
