HYDREX REINSTALLS BOW THRUSTER IN ITALY

Monday, February 18, 2019 

Underwater repairs company Hydrex reports that one month after its diver/technicians removed the bow thruster of a 300m long container ship, a team once again mobilised to Italy to reinstall the overhauled unit underwater with the use of the company’s mobdock technique.

The available time window for the removal of the bow thruster was very short because of the tight schedule of the vessel’s charterer. The time required to perform the operation therefore needed to be brought back to the absolute minimum. For this reason the job was split in parts, performed in different ports. This is a good example, says Hydrex, at how it finds a way to tailor its operation to fit the precise circumstances and the customer’s specific needs.

The time frame for the reinstallation was slightly larger, allowing the team to carry out the job during a single stop of the vessel.

Hydrex's flexible mobdock was employed to allow all water to be removed from the thruster tunnel. This created drydock like conditions for the divers despite the vessel staying afloat. The team then secured the unit and connected it to the engine room. Once this was done the thruster propeller blades were installed one by one. With the thruster blades in position the ship was ready to sail, on schedule.

Hydrex adds that it can assist shipowners with almost any problem they encounter with their vessel’s thruster. A wide range of underwater repair or maintenance work can be carried out to all types of thrusters. An entire unit can be overhauled, propeller blades or seals can be replaced or repair work on a specific part of a thruster can be performed on-site with minimal effect on vessel schedules.
