SEPTEMBER 2, 2014 — Rotterdam headquartered Van Oord Dredging and Marine Contractors bv has ordered a new subsea rock installation vessel from Sinopacific Shipbuilding Group's Ningbo shipyard in China. Delivery is set for 2016.

The vessel, which has a DP-3 (dynamic positioning) system, will be suitable for installation of a wide range of rock sizes through a fall pipe or a tremie pipe at the side of the vessel.

With a deadweight of 14,000 tons, a length of 154 metres and a beam of 28 metres, the vessel can operate in water depths of more than 600 meters and has accommodations for 60 people.

In close cooperation with the Ulstein Group special attention was paid during the design phase to the energy efficiency of the bow and hull. In addition to state-of-the-art components and materials, the vessel is being equipped with several innovative and sustainable systems, including a Green Passport, Clean Ship Notation and Ice Class 1A – PC7.

At the moment Van Oord deploys three SRI-vessels: Stornes (27,000 tons), Nordnes (26,000 tons) and Tertnes (11,000 tons).
