Variable buoyancy buoy for mooring mobile offshore drilling units |
摘要 |
In a system for mooring offshore drilling units, a first mooring assembles installed at a first drilling venue, after which the mobile offshore drilling unit is moored by connection to the mooring lines. A second mooring assembly is installed at a second drilling venue while drilling operations are carried out at the first drilling venue. In this manner the mobile offshore drilling unit can be relocated between successive drilling venues with minimum down time. Less than complete mooring assemblies can be used to temporarily secure the mobile offshore drilling unit.
