Abstract

1,153,653. Offshore platform. LITTON INDUSTRIES Inc. 10 Oct., 1966 [11 Oct., 1965], No. 50621/65. Divided out of 1,153,652. Heading E1H. A marine structure comprises three hollow columns 23, 24, 25 supporting a triangular working platform 12, the columns being capable of being flooded so that the structure can be maintained in a floating position on the surface of the water, or in a semi-submerged position in which the columns are partly submerged, or in a bottom-sitting position in water sufficiently shallow to permit the platform to remain above water level when the structure is in the bottom-sitting position, and each of the columns 23, 24, 25 is supported by a hollow footing such as 27 at its base, the footings having a boat shaped contour and being orientated to define a centre line in the direction in which towing meets least resistance, those footings 31, 32 which support the stern columns being toed-in with respect to the centre-line.
