Norway’s Kongsberg Maritime has successfully secured a contract with China Merchant Heavy Industries (CMHI) to design and equip two construction service operation vessels (CSOV) for Awind AS, a subsidiary of Integrated Wind Solutions AS. The total contract value is approximately NOK 250 million ($30.2 million). These vessels are intended for the growing offshore wind market and will be built using Kongsberg Maritime’s innovative UT 5519 DE design. The scheduled delivery of the CSOVs is set for 2023.
Kongsberg Maritime’s comprehensive equipment solution includes advanced technologies such as permanent magnet azimuth thrusters, generators, electrical systems, a fully integrated bridge featuring navigation, dynamic positioning (DP), and automation, along with deck machinery and control systems. This extensive offering is expected to enhance activity across Kongsberg and within its subcontractor supply chain.
The UT 5519 DE design incorporates a unique hull form and propulsion system, informed by both research and development and operational experiences from previous wind farm service vessels. The propulsion setup features four KM type US 255 L azimuthing thrusters—two positioned at the front and two at the rear—powered by efficient permanent magnet electric motors. This configuration ensures exceptional maneuverability, station-keeping capability, and overall efficiency, which is crucial for vessels required to service a significant number of wind turbines each day.
Kongsberg Maritime has highlighted the hybrid power system of these vessels, which consists of energy storage systems and a DC main switchboard. This system allows for spinning reserve and enhances operational efficiencies through techniques such as peak shaving, power boost, and short-term battery operation. The design aims to minimize the running of generators, thereby optimizing fuel efficiency. The generator sets are variable RPM, enabling optimum fuel consumption even under low load conditions.
Moreover, the vessel aims to reduce its environmental impact in various ways. It is designed to meet the DNV Silent(E) class notation, which addresses underwater noise, reflecting Kongsberg Maritime’s commitment to developing next-generation CSOV/SOV designs that support the transition towards zero-emission operations.
The vessel layout also strategically separates work and living areas to facilitate 24-hour operations while ensuring a high standard of living comfort for crew members, with accommodations designed for up to 120 people. In summary, Kongsberg Maritime’s engagement in this project not only represents a significant advancement in offshore wind service capabilities but also underscores the company’s focus on sustainability and innovative design in the maritime industry.
