In a contract worth approximately $13 million, Kongsberg Maritime has secured a contract to equip a new heavy lift crane vessel for Offshore Heavy Transport (OHT) with an appropriately innovative technology suite. The vessel, a customised Ulstein Design & Solutions BV design, marks the entry of the Norway-based Offshore Heavy Transport (OHT) into the offshore renewables and installation market. Options exist for a further three vessels, but the first is currently under construction by China Merchants Heavy Industry (CMHI) and is scheduled to enter service in 2021.
The revolutionary 216.3m, 48,000DWT (deadweight tonnage) vessel has been designed with a submersible main deck and a 3000mt (metric tons) lifting capacity main crane to expedite heavy-lift crane operations for heavy substructures supporting offshore wind turbines. KONGSBERG’s integrated technology solution will be integral to the vessel’s operational effectiveness. The suite will include dynamic positioning, navigation, thruster control and automation systems, all enhanced by inbuilt measures to improve functionality and safety. The delivery will be augmented by an electrical package including battery hybrid power and energy management systems, which will perpetrate a sharp reduction in fuel oil consumption, thereby driving down the vessel’s CO2 and NOx emissions.
