DECK INSTALLATION SYSTEM FOR OFFSHORE STRUCTURES

摘要

An apparatus and method for installing a deck (3) on an offshore substructure (15) is provided. The apparatus comprises a deck supported by lifting mechanisms (6) compressed until transported to an offshore substructure having an upper end (16) located above the water surface. The lifting mechanisms are then extended and the apparatus moved on the surface of the water to position the deck over the substructure. The deck is then lowered onto the substructure and the pontoons are lifted out of the water.
