Jan De Nul orders two vessels
Brussels: Dredging giant Jan De Nul Group has ordered two 6,000 ton subsea rock installation vessels AVIC Weihai in China.
The vessels will be able to install rock at depths up to about 600 m by means of a flexible fall pipe. An inclined fall pipe will enable accurate rock installation around structures such as offshore wind turbine foundations and oil and gas platforms, the company said in a release. The vessels will also act as a support vessel for a subsea trencher, for the burial of cables. In addition, a cable carousel with related equipment can be installed on board, for placing cables on the seabed.
To enable these functions, the diesel-electric vessels will be provided with a DP2 system.
The two ships will be delivered in 2017. No price has been revealed.
