 Belgium-based dredging and marine construction giant Jan De Nul Group has ordered two 6,000 ton Subsea Rock Installation vessels at AVIC Weihai shipyard in Weihai, 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 & gas platforms
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. 
Accommodations for 60 persons, all in single cabins, will provide comfortable living space for the crew, specialized personnel and client representatives. 
The vessels will comply with the IMO Code for Special Purpose Ships. The two sister vessels will be delivered by the shipbuilder in 2017.  No price has been revealed.
