A supplemental buoyancy system for a column stabilized semisubmersible vessel comprises an arrangement of inflatable buoyancy members 24,26 disposed adjacent to and/or within each of the column members interconnecting the vessel deck structure 16 with twin submersible hulls. The inflatable members may be supported beneath the deck structure 16 in a collapsed or partially inflated condition by a flexible containment net. Interior chambers of each of the column members can be provided with inflatable buoyancy members. The buoyancy system includes a control circuit for sensing unwanted column flooding or inclination of the deck to release pressure air for inflation of a particular set of members from a pressure source comprising a set of high pressure air storage bottles. The inflatable members are maintained in at least a partially collapsed condition by a pressure monitoring and alarm system adapted to indicate leakage in any one of the inflatable members. The buoyancy members may be foamed members alternatively. <IMAGE> |
