Shell Corrib Field Case Study

Project Description

The Corrib gas project is one of the most significant engineering projects ever undertaken in Ireland. Located some 83 kilometres off the northwest coast of County Mayo, this medium sized gas field will be developed as a subsea ‘tie-back’ facility, connected by a pipeline to an onshore processing terminal.

The Corrib Gas Partners are Shell E&P Ireland Limited (45% – Operator), Statoil Exploration (Ireland) Limited (36.5%) and Vermilion Energy (18.5%).


The Corrib development is made up of four components:

  1. The offshore well and sub-sea infrastructure;
  2. The offshore pipeline and umbilical
  3. The onshore pipeline and umbilical connecting the offshore pipeline and umbilical to the terminal
  4. The gas terminal at Bellanaboy Bridge.

The offshore sub-sea infrastructure, the offshore pipeline, and the terminal at Bellanaboy are substantially completed. Construction of the onshore pipeline, which includes a tunnel under Sruwaddacon Bay is now well under way. The laying of the offshore umbilical between the landfall at Glengad and the Corrib subsea manifold was completed summer 2013.
