<p>Work ship used to install a large offshore structure such as a marine plant onto a foundation structure installed in the sea by transporting the structure to the installation field. The ship has a lower hull (2), a plurality of guide posts (3) along both sides of the hull (2), an upper hull (4) mounted on both sides on the posts (3) so that it can be raised, and elevation devices (5) for raising the hull (4) up the posts (3). The hull (4) is raised up the posts (3) to the same height as the foundation structure, thereby enabling the easy moving and positioning of the offshore structure from the hull (4) onto the foundation structure without the use of a crane ship or the like.</p> |
