Offshore drilling platform construction

Patent ·
OSTI ID:7069074

Four legs of spuds engaging the sea bed support an elevated, elongated platform above the water to form an I configuration defining a pair of barge-receiving slots into which different barges can be moved and raised to the platform level by jacking mechanisms. The arrangement permits unit chassis type operation by which first a drilling barge with a derrick can be introduced and then, after drilling, this barge can be removed and the slot occupied by a production barge, leaving a servicing slot vacant for future work.
