ABSTRACT:
The present invention provides a lifeboat disengagement system for supporting and releasing a twin fall lifeboat, the system comprising a single lifeboat release assembly and a pair of hook assemblies for releasable engagement with a corresponding pair of lifting links. The lifeboat disengagement system includes an engaged configuration wherein the lifting links are secured by the hook assemblies, and a disengaged configuration wherein the lifeboat release assembly is employed to release the lifting links from the hook assemblies simultaneously. The lifeboat disengagement system provides positive locking under load including a load over center design such that a load of the lifeboat is in line with a center of hook rotation, thereby preventing the hook from opening inadvertently and eliminating the need for a hydrostatic device.
