More Information
Summary:Described is a device for lifting an elongated object from a deck of a vessel subject to movements in a heave direction. The device comprises rigid supports provided on the deck of the vessel for supporting the object at a first height relative to the deck, and retractable supports provided on the deck of the vessel for supporting the object at a second height relative to the deck, which second height is larger than the first height. A lifting crane is configured to take up the object from the retractable supports at the second height. An actuator system is configured to lower the retractable supports in the heave direction to a third height relative to the deck at the instant in time the object is lifted from the retractable supports, the third height being smaller than the second height. A method using the device is also described.
