Underwater ship repair company Hydrex said one of its teams has removed a bow thruster from a 170-m container ship in Rotterdam
Hydrex sent a repair team to the vessel using one of the company’s workboats equipped with a dive support station with hydraulic cranes, winches, nautical and communication equipment, and a dive control room.
After the team set up a monitoring station, divers began a detailed inspection of the bow thruster and tunnel. Initial preparations were made in the bow thruster engineroom to remove the unit so there would be no ingress of water once it was taken out.
Once the gearbox was secured with hoisting equipment, the Hydrex team disconnected the unit from the engineroom and lowered it onto a sledge designed especially for such thruster operations. The thruster unit was removed with the blades still attached.
Hydrex said the removal process was carried out in line with the specific procedures required by the OEM. The tunnel was sealed off from the bow thruster room and once the unit was lifted onto the quay, it was prepared for transport to the workshop.
