System and method for releasing a barge from a topside during a float-over installation

摘要

A quick-release system for coupling a topside for a fixed or floating platform and a barge for float-over installation of the topside is disclosed. The quick-release system comprises one or more releasable connections, each releasable connection configured to support at least a fraction of the weight of the barge and to be remotely actuated to allow the barge to decouple from the topside. In some embodiments, the quick-release system comprises two plates, one coupled to the topside and the other coupled to the barge, and a plurality of bolts extending therebetween. A frangible nut is coupled to each bolt. The quick-release system is actuatable by an electric signal that causes the frangible nuts to fracture and the barge to subsequently be released from the topside.
