Ship history
Working in close cooperation with Van Oord, this is the first fully integrated design where Ulstein has been responsible for the development and integration of both the mission equipment and vessel design. SRI vessels stabilise and protect subsea pipelines, cables and other structures at the sea bed.
Rocks can be installed through a fallpipe inserted through the moonpool, through a fallpipe over the side or through a tremie pipe over the side. The vessel can perform subsea rock installation close to offshore platforms.
The DP-3 vessel is a unique design featuring the distinct X-BOW® hull line and meets the requirements for Clean Design Notation, Green Passport and Ice Class 1A – PC7. The vessel and its equipment are designed for year-round operability in harsh weather and high-sea states.
Ulstein has also supplied the main Fall Pipe Deployment system and the majority of the ancillary systems of the rock installation tower. Ulstein puts a strong focus on simplicity, by mechanizing 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.
Combined with its ability to load and install large rocks, this makes the Bravenes ideal for the offshore wind and cable market.
