Van Oord has ordered two new subsea rock installation vessels capable of operating on methanol from Yantai CIMC Raffles Offshore in China. The first vessel is expected to enter the market in 2028, with a second vessel to follow within one year.
Subsea rock installation is vital for protecting and stabilising offshore energy assets. Van Oord has ordered the new vessels to meet the rising global demand for offshore energy infrastructure protection.
The offshore contractor currently operates three subsea rock installation vessels: Stornes, Nordnes and Bravenes. The new vessels will build on this proven platform, offering key upgrades to meet future offshore challenges.

Maximum capacity, minimal impact
The new vessels will be equipped with a substantial loading capacity of 35,000 tonnes, will be capable of handling large rock sizes, and feature a DP-2 dynamic positioning system. This advanced system will enable the vessels to maintain precise positioning despite challenging conditions such as waves, wind and currents. These features will make the vessels ideal for long-distance projects, as they will minimise round trips, reducing emissions and costs per installed rock volume.
‘Through innovative technologies and long-term investments, we actively contribute to greater energy security and energy independence for countries,’ says Maurits den Broeder, Managing Director Offshore Energy at Van Oord. ‘Particularly in times when securing critical underwater infrastructure is a priority, this investment is important. These new vessels embody our commitment to innovation, safety, sustainability and efficiency, while supporting the growing demands of our clients and our own net-zero ambitions.’

Sustainable technology
The sustainable design of the vessels includes multi-fuel engines (biofuel and methanol), a DC-grid with large battery storage capacity, and an energy-efficient hull design and rock handling system. These technologies enable a reduction in CO2 emissions, supporting Van Oord’s net-zero strategy.
