Shellfish are being blamed for bringing a ferry to a halt for seven hours. Pride of the Tyne was on its regular service between North Shields and South Shields when one of its engines stopped in midstream.
After limping to its berth, engineers discovered that the engine’s inlet cooling pipe had become blocked by an invasion of growing baby mussels. It took seven hours to strip down the engine, find the cause of the problem, and clean out the pipe.
