Method of removing or positioning a substructure of an offshore platform |
摘要 |
The method for removing or positioning a structure (103) which is erected on either an underwater bed or anchored to the underwater bed entails the use of a hoisting mechanism. When the structure (103) is being removed, it is detached from the underwater bed. Then, the structure (103) is connected to a hoisting mechanism which is arranged on a separate hoisting vessel (100). The structure is hoisted up by the hoisting mechanism and is attached to a transport vessel (1) in such a manner that it can tilt about a horizontal axis. Then, the structure is tilted into a substantially horizontal position. The structure is positioned in the reverse order.
