SYSTEM AND METHOD OF EXECUTING AN UNDERWATER WELL DRILLING PROGRAM IN THE BED OF A BODY OF WATER, AND AUXILIARY FLOATING UNIT

摘要

A system for executing an underwater well drilling program in the bed (2) of a body of water (3) has a jack-up (1) having a floating structure (6) and a drilling installation (8) supported on the floating structure (6); and an auxiliary floating unit (12) connectable selectively to the jack-up (1) to allow transfer of the jack- up (1) over the body of water (3), even in very shallow water.
