Renewed series of Subsea Knuckle Boom Cranes
Huisman has announced the launch of a renewed series of subsea Knuckle Boom Cranes for the use in the offshore subsea construction market. With this new series, the company’s portfolio has been adapted to the latest trends in offshore construction vessels with respect to energy efficiency, automation, and safety.
New series with models from 85mt up to 350mt
The new, optimised series includes models starting from 85mt up to 350mt 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. Furthermore, Huisman’s award-winning and patented Fiber Rope solution can be offered as an option on several models of the range to increase the lifting capacity at depth.
Fifth generation of its motion controller “HMC 05c”
The Knuckle Boom Cranes come with the most recent version of Huisman’s Secondary Controlled Electro-hydraulic power system as standard. The origin of this secondary controlled system dates to the 1980s when Huisman pioneered application of such equipment in offshore cranes. Huisman has recently implemented the fifth generation of its motion controller “HMC 05c” in all of these models. This provides crane operators with the most responsive and accurate system on the market. With the latest improvements, interaction with the vessel’s power grid has been improved to allow for use with alternative fuels, including ammonia, methanol, or LNG.
Front-runner in Full Electric cranes
Being the front-runner in Full Electric cranes, Huisman can also 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.
“With the update of our Subsea Knuckle Boom Crane series, we respond to the market need for technical improvements on existing products. Vessel owners have more and more interest in aiming for zero emissions on their newbuild vessels. Also, battery banks on vessels are not only used for “spinning reserve” anymore, but can serve multiple roles on the vessel, all focused on using the energy more efficiently.
