1,070,358. Mooring and trimming vessels. CAMMELL LAIRD & CO. (SHIPBUILDERS & ENGINEERS) Ltd. March 30, 1966 [April 10, 1965], No. 15344/65. Headings B7A, B7M and B7S. [Also in Division E1] A marine platform capable of floating horizontally or vertically and suitable for location where the depth of water is 10,000 to 15,000 feet comprises an upper structure (10), Fig. 1 (not shown), a slender tubular steel column or hull (11) of length about 450 feet, a keel-like member (25), Fig. 4 (not shown), positioned on the hull so as to control the swing of the hull from the horizontal to the vertical and means for releasing iron shot (33), Fig. 8 (not shown), contained in the keel as the hull approaches the vertical. When this vertical position has been reached the keel (25) may be unshipped and recovered for use on another hull. The hull (11) is moored to an anchorage on the sea bed by three mooring ropes (55), (56), (57), Fig. 19 (not shown), the lengths of which are adjusted so that a part of each rope spans in a catenary from the sea bed to the marine platform.
