OFFSHORE PLATFORM WITH MOVABLE CANTILEVER EXTENDING BEYOND THE DECK

摘要

This invention relates to an offshore system comprising a rig having a deck (2)and further comprising a cantilever (4), which is mounted on the deck and whichis at least moveable in a longitudinal direction of the cantilever between a retractedposition and an extended position. Said cantilever has an operational end (4a)which extends beyond the deck in an extended position of the cantilever, and aninner end (4b) opposite the operational end. Furthermore said cantilever hasone or more cantilever support rails (10) in the longitudinal direction of thecantilever. The system further comprises support means (7) comprising railengagement members (7a) which allow longitudinal movement of the cantilever.The system further comprises a support rail extension part (6b') for eachcantilever support rail, that allows to extend the cantilever support rail atthe inner end of the cantilever by being positioned in line with the cantileversupport rail, for the purpose of increasing the length of the cantilever supportrail and thereby the longitudinal reach of the cantilever.
