Trawl Swept Pipeline Gates

Trawl Swept Pipeline Gates are areas of seabed where a fishing vessel has conducted trawl sweep operations, to reduce the impact of heavy spoil that has been excavated when a new pipeline is installed. A fishing vessel will tow a chain mat, followed by fishing gear across the pipeline to lessen the impact of spoil and create areas of seabed that are assigned as Trawl Swept Pipeline Gates.
