Work barge with dive control station, Hydrex diver and bow thruster on the far right.
the inspection, the thruster was secured and the brackets connecting it to the tunnel were cut. As soon as the thruster tunnel had been sealed off, the unit was carefully lowered, removed from the tunnel and brought onto a work barge. From there it was transported to the workshop for fault diagnostics. In the meantime the spare thruster was
lowered into the water and brought inside the thruster tunnel where it was secured. Once this was done, a team onboard the vessel started the reinstallation of the unit while the second team simultaneously started the fitting of the propeller blades. When both teams had completed their parts of the operation, a successful test was carried out which concluded the repair. Dur ing thi s operat ion the
diver-technician teams worked in shiſts to make sure that the repair would be
finished before the vessel had to depart and this despite the unavoidable loss of time that the poor weather conditions brought about. As a result of the Hydrex
technicians’ work, the vessel is now able to once again use its thruster to manoeuvre when in port without depending on external assistance. SRCT
