Abstract
An offshore structure for the production of hydrocarbons is constructed and arranged to rest on a base over predrilled wells in a sea bed. A moveable base plate closes the base. Attached to the base plate are a plurality of conductors which are placed in fluid communication with the predrilled wells. During positioning of the structure on top of the predrilled wells, the base plate is moveable to facilitate mating of the base plate with the predrilled well. After the base plate is in place, the base is lowered into engagement with the base plate.
