Maintenance
Copenhagen Subsea thrusters are engineered for extreme durability and reliable operation for many years. Their robust construction ensures long-term performance, but proper care is essential to maximize lifespan and efficiency
How to
Inspect and clean your thruster
Due to their construction, our thrusters are extremely robust and durable. However, it is important to take good care of the thruster. Proper care will ensure longevity and reliable operation for many years.Â

Recommended Maintenance
Water flushing
In order to extend the lifetime of the thruster, it should be flushed with fresh water after use to protect internal components

The thruster has a coupling nozzle placed on the flange ring. A Ø6×1 hose will fit the coupling nozzle. Flush the thruster with plenty of fresh water through the hose and turn the propeller round by hand during flushing.
Inspection & Cleaning
Check bearings, rotor, and stator regularly (first at 50 hours, then every 200 hours). Disassemble if needed for deeper cleaning

This is done in two steps.
First, apply the bearing puller and remove the bearing ring. Second, apply the rotor puller and pull out the rotor.
The first visual maintenance inspection must be done after 50 hours of operation. Hereafter, visual maintenance is only required after each 200 hours of operations for the rest of the thruster’s lifetime.

Propeller Exchange
Quickly replace if damaged or to improve hydrodynamic efficiency
Please note: The thruster must not be activated without water to lubricate the bearings
