BLRT Repair Yards Convert General Cargo Vessel , GRACE, to Cable Recovery Vessel for Mertech Marine – Video

 

Since 2004 Mertech Marine has been recovering out of service cables using its own marine fleet, dismantling and recycling cables in their own factories pioneering and innovating turnkey solutions to the submarine telecommunication industry.

They have recovered in excess of 100,000 km of out of service cable which has been acquired from the cable owners.

From their base in Port Elizabeth, South African, the company has now announced the start of the first cable recovery voyage of their newly converted cable recovery vessel, GRACE.

The conversion of the general cargo vessel GRACE to become a fully equipped cable recovery vessel was carried out by the BLRT Repair Yards.

Mertech’s long-term partner, the Dutch based cable transort, handling and storage company, WIND managed the conversion for them at the repair yard.

BLRT Repair Yards unites three ship repair yards: Tallinn Shipyard in Estonia, Western Shiprepair in Lithuania and Turku Repair Yard in Finland. The work for this conversion was carried out at the Tallin Shipyard in Estonia.
