Subsea 7, a global provider of seabed-to-surface engineering, construction and services, has taken delivery of Seven Arctic and Seven Kestrel, successfully completing a substantial and targeted fleet investment programme that has added six new-build vessels to the Subsea 7 fleet since 2014.

Seven Arctic is a heavy construction flex-lay vessel designed to meet the demands of deep water and harsh environments. Capable of working at depths of 3,000 metres, the vessel features a 1,000-tonne offshore crane and a 600-t top tension (tiltable) lay system.

Seven Kestrel is a modern dive support vessel, certified by DNV-GL, encompassing an 18-man twin-bell saturation diving system rated to 300m water depth.

These vessels were built to a high specification, designed by Subsea 7 engineers in collaboration with Hyundai Heavy Industries Shipyard in Ulsan, South Korea and

Wärtsilä Ship Design, Norway, to maximise their efficiency, capacity and economy.

John Evans, Chief Operating Officer says, “We have one of the most modern, capable and diverse fleets of vessels in our market segment that differentiates our industry leading service. The arrival of Seven Arctic and Seven Kestrel further strengthens our fleet and client offering. Seven Arctic delivers an important step change in our subsea construction capability, particularly in ultra-deep water fields which pose increasingly technical challenges, whilst Seven Kestrel reinforces our leading diving capabilities.”

Both vessels will transit to the North Sea for further crew familiarisation before commencing operations in the spring.
