| 发明名称 | Remote heave compensation system | ||
| 摘要 | A remote heave compensation system associated with a crane on a vessel may include a heave compensator arranged remotely from the crane and configured to translate in association with and to compensate for heaving motion of the vessel, an equalizer arranged on the crane and coupled to an end of a multiline system of the crane, a heave line secured to the equalizer at a first end and secured to the heave compensator at a second end, wherein compensating motion of the heave compensator is transferred to the equalizer by the heave line to compensate for heaving motion of the vessel and stabilize objects suspended from the multiline system of the crane. | ||

| 主权项 | 1. A remote heave compensation system comprising: a heave compensator configured for arrangement at a remote location from a crane and configured to translate in association with and to compensate for heaving motion of a vessel supporting the crane; an equalizer configured for arrangement on the crane and further configured for coupling to an end of a multiline lifting and lowering system of the crane; and a heave line, separate from the multiline lifting and lowering system of the crane, secured to the equalizer at a first end, configured for extending along a portion of the crane and off of the crane to the remote location of the heave compensator, and secured to the heave compensator at a second end, wherein, compensating motion of the heave compensator is transferred to the equalizer by the heave line to compensate for heaving motion of the vessel and stabilize objects suspended from the multiline lifting and lowering system of the crane. | ||
