Diverless pollutant recovery

Polrec, a joint development by marine salvor Smit Tak and pumping specialists Frank Mohn Flatoy, is designed to recover oils, chemicals and other pollutants from wrecks at shallow and deep water locations.

The system uses the Frank Mohn Remote Operated Offloading System (ROLS). The ROLS descends to the wreck, where it is positioned by a ROV. It then penetrates the cargo and bunker tanks in a one phase `hot-tap` operation. Pollutants are then pumped to a surface working platform equipped with reception facilities. The process is fully automated and pollution-free, says the company.
