Abstract

1,048,776. Offshore floating structures. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 12, 1965 [April 13, 1964], No. 15505/65. Heading E1H. A floating platform unit for carrying out offshore operations such as drilling or producing a well comprises three or more vertical stabilizing columns such as 11, 12 with buoyant crossbracing hull members 14, 15, 16, 18 attached near the lower ends thereof, rigid motion damping keels 40 extending substantially horizontally from either the outboard, inboard or both sides of the cross-bracing hull members. The keels may either extend the full length of the hull members or may consist of several short sections. They may be provided with holes 41 to increase their effectiveness so that pitching and rolling are considerably reduced in heavy weather.
