Odin on stream

Supported on a conventional four-leg steel jacket, the platform was designed by McDermott Norge A/S. Its jacket was built by the Dragados yard in Spain, while Aker Stord Verft in Norway fabricated the module support frame and gas treatment modules. The drilling modules were supplied by Mannesmann in the Netherlands, and the 48-berth quarters module came from Nymo in Grimstad, Norway.

Semac I began laying the 20-inch pipeline from TCP2 on Frigg to Odin in March 1982. This line lay uncovered on the seabed for most of its length.

The Odin platform was installed during July 1983 in 103 metres of water. While the jacket weighed 6 200 tonnes, the module support frame and modules with drilling and processing equipment, quarters and helideck totalled about 7 600 tonnes. Oil Industry Services (OIS) in Kristiansand was responsible for hooking up the modules and testing that everything functioned.

Drilling of the 12 production wells began in December 1983 and continued until 26 January 1985. Although the Odin platform had its own derrick, it was dependent on support from the Treasure Hunter rig to handle mud and drillpipe/casing during the drilling phase. An additional 140 workers were required for the installation and drilling phase, and they were accommodated on Treasure Hunter.

Odin began production on 1 April 1984, as soon as the first well was ready.
