Trawl Sweep Vessels

Trawl sweep vessels conducting overtrawlability trials are often engaged by a variety of clients, including major international oil and gas operators and installation companies. The aim of trawl sweep operations is to declare a potentially hazardous area clear, and safe for fishing activity to resume following any offshore installation and/or decommissioning operations. Installation and back filling of pipelines or other subsea structures can result in damage to the seabed, and clay berms which are dangerous for trawling. Similarly decommissioning and abandonment can leave behind debris and significant snagging hazards. Undertaking overtrawlability trials immediately post-installation or post-decommissioning helps prevent potential problems, and a clearance certificate gives Operators insurance against future liability.
