Looking back at the installation of the Gyda Oil and Gas platform

1989 saw the installation of a major North Sea Oil & Gas platform on the Gyada field.

Located in the southern Norwegian sector of the North Sea between the Ula and Ekofisk fields, the Gyda field was first discovered in 1980.

It was estimated that the field held 37.7 million cubic metres of recoverable oil reserves, and 6.6 billion cubic metres of gas. The Gyda platform was constructed for production from the field, with installation planned for 1989 and start up in 1990.

The platform comprised an integrated steel jacket and four topside modules with offshore drilling and processing facilities as well as living quarters. The modules were mounted directly on an eight-legged cellar deck which is fixed to the six-legged jacket which stood in approximately 66m (217ft) of water. 

The jacket had a lift weight of 8,200 tonnes and was bored under the seabed. It housed 32 conductors out of which eight had a 500mm diameter and were tied-back to the subsea wellheads. The remaining 24 has a 685 diameter run. 

Oil produced from the field was piped to the Ekofisk field from where it could be transported to Teeside in the UK. Gas was transported from Ekofisk on to Emden in Germany.

The Gyda platform delivered successful production for three decades. Gas export was stopped in 2016, when a decommissioning plan was also submitted to the Norwegian authorities.

Decommissioning is due for 2023 at a cost of $623.8 million. Repsol have awarded Allseas the engineering, procurement, removal and disposal (EPRD) contract. But the platform itself may live on, as it has been earmarked for preservation for potential redeployment to another field…
