OHT Alfa Lift. Scheduled for delivery in 2021, Alfa Lift will be the world’s largest custom-built offshore wind foundation installation vessel, equipped with a 3,000t main crane. The ship’s 10,000+ square meter smart decks will carry up to 14 XL monopiles per voyage and will also be fully submersible to a depth of 14.66m.

Under the terms of the contract, MacGregor will deliver a motion-compensated pile gripper frame, while KONGSBERG’s PGGS will integrate the gripper with the many other KM systems on board the OHT Alfa Lift. A K-Pos dual-redundant dynamic positioning system will interface with a K-Chief marine automation system and K-Thrust thruster control system, bringing all the technical and economic benefits which result from the integration of a vessel’s monitoring and control functions, while a K-Bridge integrated navigation system will provide a single, intuitive user interface for the ship’s multiple connected systems. A full suite of safe, reliable, compact and cost-effective K-Power products will accommodate the main switchboard, generators and drives, while KM’s azimuth and tunnel thrusters will take care of the vessel’s propulsion, steering and positioning thrust.

Kongsberg Maritime and MacGregor have both been working in close collaboration to develop this new, integrated monopile installation solution, incorporating KM’s most sophisticated, up-to-date automated handling functionality. By removing the need for temporary mooring procedures during installation operations, the solution will enhance safety, productivity and mission consistency, generating substantial savings in time and money for the specialist transport and installation contractor OHT. In time, these positive changes will be reflected in a wider sense when the concept is rolled out across the offshore wind energy market.
