Serimax recently fabricated, field joint coated and hydrotested an 85m pipe-in-pipe I-spool on behalf of Technip for Dong Energy’s Oselvar field in the Norwegian North Sea. The I-spool comprises a 10in Super Duplex pipe, insulated along its length, in a 14in carbon steel pipe externally coated with three-layer polypropylene. The workscope also included fabrication of the five outrigger sea-fastening structures required to support the I-spool on the installation vessel.
The project was carried out at a quayside fabrication facility recently set up by Serimax at Cromarty Forth Port Authority’s Invergordon base in the north of Scotland.
