Kongsberg Maritime to design and equip Awind’s


The Norwegian company Kongsberg Maritime has signed contracts with China Merchant Heavy Industries (CMHI) to design and equip two construction service vessels (CSOV) for Awind AS.

Awind AS is an offshore shipowner based in Norway and a subsidiary of Integrated Wind Solutions AS. The overall contract value for Kongsberg Maritime is approximately NOK 250 million ($ 30.2 million).

Intended for the offshore wind market, the new CSOVs will be built according to Kongsberg Maritime’s UT 5519 DE design by CMHI. The ships are expected to be delivered in 2023.

Kongsberg Maritime’s integrated equipment solution includes permanent magnet azimuth thrusters, generators, electrical systems, fully integrated bridge with navigation, DP and automation, bridge machinery equipment and control systems.

This broad portfolio will contribute to the activity of the entire company and the subcontractor supply chain network, Kongsberg Maritime said.

The UT 5519 DE has a new hull shape and propulsion configuration, incorporating the results of research and development projects as well as operational experience from KM’s wind farm service vessel designs, the company said.

“The propulsion is provided by four US 255 L type KM azimuth thrusters, two at the front and two at the rear. The thrusters are powered by highly efficient, vertically mounted permanent magnet electric motors. provides excellent maneuverability and excellent hold and efficiency, which is important for a vessel that visits a large number of wind turbines each day, with operations including close maneuvering, holding and transits short, ”Kongsberg Maritime explained.Credit: Kongsberg Maritime

According to Kongsberg Maritime, the hybrid power system includes energy storage systems and a DC main distribution board configured to provide spinning reserve, as well as active efficiency during vessel operation by cutting back on peaks, increased power and the possibility of short-term battery operation. This minimizes the number of generators running and optimizes energy efficiency. The generators are variable speed, allowing optimum specific fuel consumption even at low load.

The vessel is also designed to minimize environmental impact in other ways, including underwater noise covered by the DNV Silent (E) class rating, further representing how the next generation CSOV / SOV designs KM are prepared for the transition to zero emission operation, ”KM added.

Kongsberg Maritime further stated that the layout of the vessel provides good separation between work and living areas, allowing 24 hour operation and maintaining a high standard of living comfort, with accommodation for up to 120 people. people.
