Kongsberg Maritime (KM) secured contracts totalling EUR 49 million with Chinese shipbuilder COSCO Shipping (Qidong) Offshore. The agreement will see KM supply technology packages for two new NG-20000X WTIVs, which COSCO is constructing for the Denmark-based Wind Turbine Installation Vessel (WTIV) operator Cadeler.

Monitoring and control of the KM components will be handled by a K-Chief marine automation system. KM stated that its tailored energy control functionalities will optimise energy efficiency and reduce the WTIVs’ environmental footprints, and the battery hybrid electrical system includes such novel solutions as ThrustAllocator and PowerBoost to increase the vessels’ operational capability while reducing the number of engines and fuel consumption required for both crane operations and DP manoeuvring.

The vessels will also include technology for the regeneration of power from the jacking system and cranes. In an effort to further reduce the environmental footprint and minimise downtime, KM has also included its new onboard advisory system, EcoAdvisor, and a condition-based monitoring system to extend maintenance intervals and detect any anomalies in the rotating equipment.

“Cadeler is committed to providing safe, high quality and reliable offshore services, with a strong focus on safety and the environment,” said Mikkel Gleerup, CEO at Cadeler. “KONGSBERG’s innovative WTIV solution will help us to pursue new levels of efficiency and enable the world's transition to a future built on offshore renewable energies.”

“We take a genuine pride in bringing the benefits of our technological expertise to all maritime sectors,” added Egil Haugsdal, President, Kongsberg Maritime, “and the bespoke solution we have devised for wind turbine installation vessels indicates how much thought and effort we devote to facilitating and encouraging sustainable marine operations.”

Cadeler's new X-class vessels will, upon completion, be among the largest in the industry. The first is expected to be completed by Q3 2024 and has already been contracted to support Siemens Gamesa with the transport and installation of 14 MW turbines for the 1.4 GW Sofia offshore wind farm in the North Sea. The second vessel will follow early 2025.

With a deck space of 5,600 m2, a payload of over 17,600 tons and main crane capacity of more than 2,000 tons at 53 metres, the two new hybrid vessels are expected to be able to transport and install seven complete 15 MW turbine sets per load or five sets of 20+ MW turbines.
