A survival cabin for an offshore vessel includes a buoyant capsule (10), which normally hangs in a davit (30) at least partly outside a side of the vessel. The davit comprises a basically Z- shaped arm structure (35) which is pivotably supported at a considerable distance below the deck (32) of the platform, and carries the capsule at a single point. The davit is operated by a brake (42), which permits the folding- out of the davit to a position, where the capsule reaches a maximum distance from the side of the vessel. The davit pivoting is controlled by a hydraulic piston or pump brake. An accumulator in the hydraulic circuit raises the arm after release of the capsule. The capsule has a false bottom with holes to allow water inflow thus dampening impact with the water after a free drop, and it has an auto-pilot governing an azimuth propeller, which will bring the capsule away from a damaged vessel in a preselected direction. <IMAGE> |
