ULSTEIN design set for new Van Oord vessel

Offshore staff

ULSTEIN, Norway ULSTEIN has won the design and equipment contract for Van Oord’s new subsea rock installation (SRI) vessel Bravenes. Working with Van Oord, this is the first fully integrated design where ULSTEIN is responsible for the development and integration of both the mission equipment and vessel design.

Sinopacific Shipbuilding Group in China will construct the vessel for delivery in 2016.

The dynamically positioned vessel is a unique design featuring a DP-3 system and the UlLSTEIN X-BOW hull line. It meets the requirements for Clean Design Notation, Green Passport, and Ice Class 1A–C7. Furthermore, the vessel and its equipment are designed for year-round operability in harsh weather and high-sea states. The ship is able to operate in depths of 600 m (1,969 ft) and more.

Under the contract, ULSTEIN will also supply the main fall pipe deployment system and most of the ancillary systems of the SRI tower. ULSTEIN will mechanize the systems as much as possible to enable higher levels of safety and control by minimizing human interaction during the deployment and recovery of the fall pipe. The system is able to efficiently switch between various rock installation modes and a wide range of rock sizes.
