Ulstein  has been awarded the design and equipment contract for Van Oord’s new subsea rock installation (SRI) vessel ‘Bravenes’.

 

Working in close cooperation 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. The vessel will be constructed at Sinopacific Shipbuilding Group in China and be delivered in 2016.

The dynamically-positioned vessel is a unique, innovative design featuring a DP-3 system, the distinct Ulstein  X-BOW  hull line and meets the requirements for Clean Design Notation, Green Passport and Ice Class 1A – PC7. Furthermore the vessel and its equipment are designed for year-round operability in harsh weather and high-sea states.

Under the contract Ulstein will also supply the main Fall Pipe Deployment system and the majority of the ancillary systems of the SRI tower. Ulstein put a strong focus on simplicity, by mechanising the systems as much as possible, enabling higher levels of safety and control and as such minimising human interaction during the deployment and recovery of the fall pipe. The resulting system is robust and fully customised, able to efficiently switch between various rock installation modes and a wide range of rock sizes.

Main dimensions of the vessel:

Loa 154.4 m
Lpp 147.9 m
Beam (moulded)  28.0 m
Depth (main deck)  13.3 m
Draught (design)    8.0 m
Speed             13 kn
Installed power 2 x 3,840 kW
2 x 2,880 kW
Positioning DP3
Class Bureau Veritas
Ice class 1A – PC7
Complement 60 persons
