The Eager.one team was awarded the design and supply of a remotely operated Jacket Lifting Tool for South Korean offshore wind specialist SK Oceanplant.
This remotely operated Jacket Lifting Tool will be used for upcoming offshore wind projects in Asia. It will be able to handle up to 2500t jackets from the yard onto transport vessels. The HMPE (High Modulus Polyethylene) rigging design is engineered for two types of lifts; Floating inshore lifts with a sheerleg containing 4 hooks and for lifting with a land based Gantry Crane with 3 hooks, which is required for fabrication purposes (to lift the top section on the lower section).
The lifting tool is specifically designed to have flexibility for the lifting of different types of jackets. First projects will contain jackets with the following specifics:
Maximum capacity of the Jacket Lifting Tool is determined by a SWL of 2500t @ DAF 1.08. The system has a design temperature of -20°C and +45°C and will be able to handle wind velocities of 12.5 m/s average. For optimal surface protection in saline environments the complete tool has been preserved with a C5 coating system.
The Jacket Lifting Tool is further equipped with several functionalities for safe, remote operations, like:
During the fabrication process, prior to the Factory Acceptance Test (FAT), the Jacket Lifting Tool has been extensively load tested, under witness of DNV. This, in combination with thorough design review and fabrication surveys, has resulted in certification in accordance with DNV-ST-0378.
The tool has been specifically designed so that it can be disassembled into parts that fit into (standard) shipping containers. Transport to the site of the customer took place with the use of two 40ft flat racks and two 40ft standard containers.
