Abstract

A mobile offshore platform has a cantilever movable between an extended position and a retracted position and a movement system with a first guide mounted to the cantilever and oriented parallel to the cantilever, a second guide mounted to the platform hull and oriented transverse to the cantilever and at least one support runner for guided movement along the first and second guides. A proximal seafastening arrangement is provided for retaining the retracted cantilever in position relative to the platform hull. A distal seafastening arrangement is provided for retaining the retracted cantilever in position relative to the platform hull. When in seafastened condition, a first retaining portion of the distal seafastening arrangement and a second retaining portion of the distal seafastening arrangement at the platform hull are mutually engaged in a position under the cantilever. A method for seafastening a cantilever of a platform is also described. Fig. 3
