Bow Thrusters Repair And Maintenance
Bow Thrusters are propeller types that are smaller in size than propellers. Bow Thrusters are placed in tunnels on the bow and stern below the waterline and are divided into two categories, electric and hydraulic. The number of Bow Thrusters on a ship depends on its size. The usage of Bow Thrusters is limited to helping the ship to operate and maneuver at low speeds, for example maneuvering in coastal waters or while entering or leaving a port. Bow Thrusters also help tugboats to dock faster.
1) Better handling at low speeds. 2) Greater security in a harbor with bad weather conditions. 3) Helping to navigate in bad weather. 4) Save money because of fast porting.
Disadvantages of Bow Thrusters:
- Large placement costs.
- Expensive repair and maintenance.
- A very large engine is required, which requires a lot of power and space.
REPAIR AND MAINTENANCE
BEVALDIA (Manager of the branches PSOMAKARA & GAMSRO) carry out underwater maintenance of Bow Thruster and repair. A routine underwater inspection of Bow Thruster by BEVALDIA (Manager of the branches PSOMAKARA & GAMSRO) and its experienced divers include the following steps:
- Check the Bow Thrusters compartment for moisture and water leaks, causing rust.
- Engine and engine part inspection for corrosion.
- Cleaning the power supply unit.
- Bow Thruster shaft test for cracks.
- Cleaning inside the tunnels, propeller from marine organisms-growth or human activity waste.
- Propeller control for cracks or knocks or cavitation.
