Dana Petroleum's gas export/import pipeline for the Western Isles Development Project has been successfully installed on to the seabed.
The pipeline will export excess produced gas to the Tern - North Cormorant gas pipeline and import gas for lift gas and fuel when required.
The 11 kilometre long, six inch pipeline was fabricated and inspected at Subsea 7's spoolbase in Leith and installed using the Seven Navica vessel. It is the first pipeline to be installed from the recently refurbished facility.
Hugh McClure, director of capital development projects, said: "We are pleased to have completed the first part of the 2014 offshore subsea campaign safely, successfully and on schedule. This is another important milestone achievement for the Western Isles Development Project."
