The Huisman Knuckle Boom Crane (KBC) design is suitable for various applications, including offshore construction work and subsea installation. It is designed to increase safety during deck handling, ship-to-ship transfer and subsea installation, using precise load control. The new, optimised series includes models starting from 80mt up to 550mt and cover both setups with a winch below deck as well as on the back of the crane. Water depths up to 3,000m are included as standard, while deeper water capabilities can be provided as an option. Available with full electric and Hydraulic drive systems The Huisman Knuckle Boom Cranes can be equipped with a full electric drive system or a secondary controlled hydraulic drive system. The full electric drive system features a proprietary active heave compensation power management system, including a patented method to cooperate with the vessel's battery banks for re-using the regenerated power from a heave cycle for the next heave cycle. Being the front-runner in full electric cranes, Huisman can offer all cranes in this series equipped with full electric active heave compensation (AHC). With today’s focus on high-performance, high-capacity energy storage systems in offshore construction vessels, interaction with full electric AHC and large-scale energy regeneration has become much more realistic in recent years. The crane can be equipped with a unique, in-house developed secondary controlled hydraulic drive system as well that works with a constant high pressure. This gives the system a much higher stiffness than conventional primary controlled systems.
