Barry J. Abbott - Concord CA
William H. Silcox - San Francisco CA

Assignee:

Chevron Research Company - San Francisco CA

International Classification:

E02B 1700

US Classification:

405227

Abstract:

A compliant offshore drilling and producing structure is disclosed. Axial piles extend from the sea floor above the water's surface and are enveloped by sleeves extending downwardly from a rigid platform. Buoyant chambers attached to the sleeves provide an upward buoyant force in excess of the weight of the platform and sleeves. This excess upward force is counterbalanced by the axial piles through hydraulic means.

Assignee:

Chevron Research Company - San Francisco CA

International Classification:

E02B 1700

US Classification:

Abstract:

A compliant offshore drilling and producing structure is disclosed. Axial piles extend from articulated joints on a pile base at the sea floor to above the water's surface and are enveloped by sleeves extending downwardly from a rigid platform. Buoyant chambers attached to the sleeves support most of the platform weight and provide righting stability. The platform weight is supported by the axial piles through hydraulic means.
