Offshore platform deck/jacket mating system and method

摘要

A system and method for mating a preconstructed integrated deck mounted on a barge with a previously installed offshore jacket is provided. The system comprises at least two primary load transfer units, at least one secondary load transfer unit, and a plurality of drop block assemblies. The primary load transfer units are designed to absorb a portion of the weight of the integrated deck as the integrated deck is lowered onto the jacket. The secondary load transfer units are designed to engage after a portion of the weight of the integrated deck has been absorbed by the primary load transfer units and to assist the primary load transfer units in absorbing an additional portion of the weight of the integrated deck as it continues to be lowered onto the jacket. The drop block assemblies are designed to disengage the integrated deck from the barge and thereby transfer the remaining weight of the integrated deck to the jacket.
