Described is a device for lifting an object from a deck of a vessel subject to movements in a heave direction. The device comprises a support surface for the object provided at a first height in the heave direction relative to the deck. A lifting crane is configured to take up the object from the support surface at a lifting point thereof at a lifting speed. An actuator system is configured to lower the support surface relative to the deck at the instant in time at which the object is lifted from the surface to a second height in the heave direction at a lowering speed. A method using the device is also described.
