The Department of Transport, Tourism and Sport advises that preparatory works for the installation of an offshore umbilical will be carried out from Corrib Offshore Field Location to landfall. The area of activity stretches along the route of the existing Corrib offshore gas pipeline.
Works will commence in early March 2013 with a route survey and pre-cut trenching.
The vessel to be used during this initial works scope will be the Trenching Support Vessel with multipass plough “Normand Ranger” (Call sign LAMT).
A pre-trenching route survey will be carried out on the whole length of the umbilical lay route. A trench will be constructed from the subsea facilities and wells in the Corrib gas field to approx 16km offshore by utilising a subsea plough. The plough will be pulled by the trenching support vessel and could trail as far as 1700 metres behind the support vessel.
