The Aegir was built by Daewoo

Shipbuilding & Marine Engineering (DSME). In Schiedam earlier this year, she arrived at the Huisman Yard, where the pipe-lay equipment was installed, including J-lay - Heavy J-lay: 2000m (using collar clamps) - Light J-lay: 600m (using friction clamps) Rigid Reel lay – 800m Flex lay – 520m. This followed the supply of lifting equipment on-

For the Arctic, Ulstein has come up with two main ideas. The frst is the
