PURPOSE:To shorten the term of construction, by a method wherein after a platform supported by a set of suspended foundation vessels with a space between them is positioned on a foundation jacket, the foundation vessels are impregnated with water and the platform is mounted on the jacket to be fixed there. CONSTITUTION:A marine platform 20 is supported at the both ends by floating foundation vessels 30, and a barge 35 inserted between the foundation vessels 30 which are connected to the barge 35 with connecting hardwares 32. Then, the foundation vessels 30 are taken in tow to a destination by tugboats, and after the connected foundation vessels 30 and barge 35 are separately arranged, the foundation vessels 30 are introduced just under a foundation jacket 40. After that, the foundation vessels 30 are made to slightly subside due to the ballast control, and after the platform is mounted on the jacket 40, the foundation vessels 30 are separately arranged. |
