Awilco-backed Integrated Wind Solutions (IWS) has added to its offshore wind vessel orderbook in China.

The Oslo-listed company said it has declared options for two walk-to-work commissioning service operations vessels (CSOVs) at China Merchants Industry Holdings.

The deal brings the fleet to six Skywalker-class CSOVs on order there.

IWS said it has also negotiated options for two more vessels.

Delivery of the latest duo will be in the second quarter of 2025.
