Mobile offshore drilling and production platform

Abstract

The present invention relates to a mobile offshore oil drilling and production platform (10) that allows a field operator to cope with uncertainty and economically develop a small or marginal oil filed typically located in a remote location. More particularly, the invention relates to a versatile platform which includes a hull (12) extending above the level of sea to house hydrocarbon extracting and scale up or scale down hydrocarbon processing system modules and equipment with provisions to drill new wells and work-overs using modular portable vertical drilling rigs or conventional rigs, connected to a mat acting as the foundation resting on the seabed which may or may not incorporate storage, using tubular legs, and provision to even abandon the field with minimal costs and disruption. The present invention also relates to a method of installing and de-installing the oil drilling and production platform (10).
