<p>The offshore port structure (1) comprises at least one self-jacking platform (10) having very large dimensions, which is movable between a floating position and a position raised out of the water, on legs (11), each of which has in its lower part a foundation (12) for resting on the seabed. On one side, the platform has an anti-swell wall (20) and on the opposite side a ship berthing wall (50), said walls each being mounted so as to be able to be slid on the corresponding side of the platform (10) by at least one adjacent supporting leg (11) between a position retracted into the floating position of the platform and a position protruding beneath this platform in the raised position of said platform.</p> |
