<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 offshore structure to the installation field. A plurality of elevationally movable support legs (2) and elevation devices (3) for elevationally moving the legs (2) with respect to the hull (1) are provided along both sides of the hull (2) of the ship. The legs (2) are lowered onto the sea bed, and the hull (1) is raised up the legs (2) to the same height as the foundation structure, thereby enabling the easy moving and positioning of the offshore structure from the hull (1) onto the foundation structure without the use of a crane ship or the like.</p> |
