Abstract
The present disclosure describes an apparatus for suspending a connector provided on a first elongated hoisting member during a subsea hoisting operation. The apparatus includes a mechanism for holding the connector, in which, when the mechanism is subjected to a hydrostatic pressure above a threshold pressure, the mechanism is changeable to a configuration for moving past the connector while the apparatus is raised. Also described are a system and methods for moving a load between a floating vessel and a submerged position.
