Wärtsilä solutions for next-gen WTIV

The WTIV is being built at the China Merchants Heavy Industry (Jiangsu) yard for Norwegian heavy transport and WTG installation contractor OHT ASA, and is the first of two next-generation WTIVs to be added to the OHT fleet. The order with Wärtsilä was placed in May 2021.

“The aim is always to provide optimal propulsion performance for efficient vessel operations, and the advanced range of Wärtsilä solutions selected for this ship will do just that,” said Dirk Folchert, senior sales manager, Wärtsilä Marine Power. “By enabling efficient free sailing and outstanding dynamic positioning, we are at the same time contributing to the decarbonisation of shipping,” he added.

The GustoMSC NG-14000XL-G design jack-up vessel is customised for offshore wind turbine installation and XL monopile foundations. The vessel will feature a telescopic crane with a maximum capacity of 2,500t and a maximum lifting height of approximately 165 metres.

The Wärtsilä scope includes four Wärtsilä 32 and two Wärtsilä 20 engines, the Wärtsilä NOx reducer system, five steerable thrusters and one Wärtsilä tunnel thruster.

Delivery to the yard will take place during the first half of 2022 and the ship is expected to be delivered during the second quarter of 2023.
