Brent is a large field and the amount of subsea facilities to be decommissioned is significant. There are 28 pipelines included within the remit of the Brent Decommissioning project, ranging in length from 0.1km to 36km. This total includes rigid pipelines, flexible flowlines and risers, umbilicals and power cables.
The age and condition of each pipeline has been studied and a Comparative Assessment has been completed, where applicable.
The recommendations range from full removal of certain pipelines to leaving others in place.
