Abstract
A buoyancy device is described comprising a number of buoyancy members (9,9A, 9B) which are substantially equi-spaced around the circumference of a coupling member (7) and the buoyancy members (9, 9A, 9B) being coupled to the coupling member (7). At least two of the buoyancy members (9, 9A, 9B) are inflatable members (9, 9A, 9B). The inflatable members (9, 9A, 9B) are formed from a substantially flexible material such that an inflatable member (9, 9A, 9B) substantially collapses when deflated. The coupling member (7) is typically coupled to a structure, which may be a drilling rig (3) which requires to be lifted and subsequently moved, or which may be a large device such as a well head Christmas tree for an oil well which requires to be deployed in deep water.
