Statoil Connemara/Gullfaks

Statoil Connemara

Ireland Block 26/28

Landmark: Designed, engineered, manufactured, installed, decommissioned, refurbished and reinstalled in less than 18 months on another field

In 1996, Statoil ordered two horizontal subsea trees for the Connemara field offshore Ireland in the Porcupine Basin. The Connemara field was thought to have 36 mmbo, which could have provided 20% of Ireland’s annual oil requirements when operating at full capacity. In 1997, an exploration well was drilled, and by August 1997, after the completion of the wells, Statoil's testing concluded that the Connemara field was not commercial.

The subsea hardware was then decommissioned, refurbished, adapted and then reused to complete two of the wells of the Gullfaks Field. The cost of reusing of the two subsea trees was a fraction of what it would have been to purchase new hardware. This project was a milestone because it proves how flexible FMC Technologies standardized subsea equipment is and how it has the ability to be reused on different fields.
