SOUTHAMPTON-based contractor Trant Construction lost more than 1,000 tonnes of plant and materials overboard when a rock barge capsized off the Isle of Wight last week.
Ships were warned to avoid the area near Bonchurch after the barge listed, spilling its cargo of rock armour, timber railway sleepers and machinery destined for coastal protection work in Portsmouth Harbour.
Coastguards were concerned the timber could prove dangerous to other ships in the area.
Solent Coastguard watch manager Bungy Williamson said the tug that had been towing the barge was picking up floating sleepers.
Trant Construction director Simon Trant slapped a £10,000 estimate on the cargo.
