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.
