ABSTRACT:
A platform is provided for use in combination with a foundation affixable to a sea bed to provide a fixed/movable marine structure system for use at selected offshore locations. The platform is capable of alternately existing in a fixed mode in which the platform is releasably coupled to the foundation, and in a floating mode in which the platform is uncoupled from the foundation. The platform comprises a working deck, and a supporting structure including buoyancy adjustment means and securing means. The buoyancy adjustment means preferably comprises ballast adjustment means. Also provided is a marine structure system comprising a platform and a foundation, and a method of coupling and uncoupling the platform from the foundation. The system of the present invention is well adapted for use at offshore locations subject to conditions which may require a platform to be both relatively rigid and stable on site at times and to be safely moved off site at other times. Such locations include areas subject to severe weather conditions and periodic intrusion of icebergs or ice floes. The platform is well adapted for use as an oil or gas production platform.
