Tough chain reaction

A typical subsea operation involving J D Neuhaus air and hydraulic operated chain hoists was recently shown on the National Geographic 'World's Toughest Fixes' programme. It covered the removal, repair and eventual replacement of a damaged 50 tonne rudder from a fully loaded bulk cargo vessel. After breaking down while hauling iron from Brazil to China, the vessel had been towed to a safe mooring off Venezuela. The operation involved the underwater setting up and rigging of three air operated JDN Profi 25Ti hoists (offering 25 tonne lift capacity each).

J D Neuhaus has invested in a R&D programme for specialised handling products for subsea operations with minimum maintenance/repair afterwork. Two hoists, the Profi 3Ti and 6Ti offer 3.2 and 6.3 tonnes lift capacities, and have been introduced as specialised subsea products.
