The Netherlands-based Van Oord announced Monday that it has ordered a new subsea rock installation vessel. Sinopacific Shipbuilding Group Shanghai will build the vessel at its Ningbo yard in China. The vessel will be delivered in 2016. Subsea rock installation is a proven technique for the protection and stabilization of offshore structures and pipelines, and is one of Van Oord’s main activities for its clients in the oil and gas industry.
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 505 feet (154 meters) and a beam of 91 feet (28 meters), the vessel can operate in water depths of more than 1,968 feet (600 meters). There is accommodation on board 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). The vessel will strengthen Van Oord’s leading position in subsea rock installation. This investment forms part of the Van Oord strategy to offer a complete service to its worldwide clients as specialized engineering, procurement and construction (EPC) contractor.
