INSTALLATION AND REMOVAL OF DECKS ON AND FROM OFFSHORE STRUCTURES

摘要

A method of installing a deck on an offshore support structure includes the steps of transferring the deck (3) onto a first vessel (1), bringing the first vessel (1) into the vicinity of a second vessel (2), connecting the first vessel (1) to the second vessel 2, bringing the combination of the first and second vessels into a position in which the support structure (14) is located adjacent to the second vessel (2), transferring the deck (3) from the first vessel (1) to the second vessel (2), transferring the deck (3) from the second vessel (2) to the support structure (14), and removing the first and second vessels from the vicinity of the support structure (14). The method for installing a deck (3) on a support structure (14) can be carried out mutatis mutandis in reverse, for removing a deck (3) from a support structure (14).
