Device for lifting objects from moving vessel deck
A recently granted patent (Publication Number: US11965478B2) discloses a device and method for lifting objects from a vessel deck experiencing heave movements. The device includes a support surface at a first height, a lifting crane, a force sensor to detect when the object is lifted, and an actuator system to lower the support surface to a second height at the lifting moment. The actuator system features distance-varying means to adjust the distance between the support surface and the base surface, with some means aligned with the heave direction and others at an angle. The device can be used for lifting wind turbine foundation elements and is suitable for floating vessels operated from a separate vessel with dynamic positioning or mooring systems.
Furthermore, the patent includes a method for lifting objects from a vessel deck, involving positioning the object on the support surface, lifting it with a crane, and activating the actuator system to lower the support surface at the lifting moment. The method also includes monitoring vessel movements to determine the lifting time and adjusting the distance between the support and base surfaces using the distance-varying means. The device can accommodate multiple support surfaces on the deck, with a base platform structure capable of moving across the deck in surge and sway directions, positioning itself under each support surface using wheels on rails. This innovative system offers a solution for lifting objects on vessels experiencing heave movements, ensuring safe and efficient operations on floating vessels.
