Subsea 7 has taken delivery of its new reel-lay vessel Seven Vega. The Royal IHC built ship is designed to install complex rigid flowlines including pipe-in-pipe systems, piggyback systems and electrical trace
heating, in water depths up to 3000 metres.

‘We are pleased to add Seven Vega, one of the most capable and cost-effective reel-lay vessels in the market, to our fleet,’ says Phil Simons, Executive Vice President Projects & Operations Subsea 7. ‘The vessel is an important, long-term investment and sets a new standard for offshore pipelay. It has been purposely designed to install economical flowline technologies that address the growing market trend towards longer tie-back developments. This includes complex pipe-in-pipe, piggyback and electrically heat traced flowline systems, risers, umbilicals and structures in water depths up to 3000 metres.’

The 21,334-GT ship measures 149 x 33 metres and has a total reel storage capacity of 5600 tonnes. It can lay single pipe of up to 20-inch. The maximum dynamic top tension is 600 tonnes. The ship has accommodation for 120 persons and a heave compensated 250-tonne crane. The ship si also equipped with 2 work-class ROVs (remotely operated vehicles).

He adds: ‘Seven Vega is more than a state-of-the-art vessel with high specification and enabling technologies. The vessel incorporates decades of knowledge and experience, resulting in a cutting-edge pipelay vessel focused on crew safety, operational efficiency and flexibility. We are grateful to the build team and our suppliers for their contribution in delivering this exceptional vessel and we look forward to commencing offshore operations in the coming weeks.’

Seven Vega is currently loading pipe for its first project.
