Device for lifting objects from a moving vessel deck
A recently granted patent (Publication Number: US11965478B2) discloses a device and method for lifting objects from a vessel's deck that is subject to movements in a heave direction. The device includes a support surface for the object at a first height, a lifting crane, a detector with a force sensor, and an actuator system with distance-varying means to lower the support surface to a second height at a specific instant. The actuator system is designed to adjust the distance between the support surface and the base surface, with some distance-varying means aligned in the heave direction and others at an angle.
Furthermore, the patent details various configurations and features of the device, such as the support surface being above the deck, the actuator system's lowering speed being a percentage of the lifting speed, and the use of a hydraulic system to interlink components. The method involves positioning the object on the support surface, lifting it with the crane, and activating the actuator system to lower the support surface at the precise moment the object is lifted. Additionally, the device can be used on floating vessels, with the lifting crane operated from a separate vessel, and is particularly suitable for lifting foundation elements of wind turbines. The device also includes a control system to manage the lifting process efficiently.
