PROPELLER CUTTER REPLACEMENT
DIVING TASK Underwater Services Hong Kong undertakes underwater rope-cutter replacement. The underwater rope-cutter replacement must be carried out directly when it fails, to avoid serious damage to the ships propeller shaft.
Rope Cutter function
The rope-cutter is placed at the base of the propeller to protect it from engagement of ropes and nets during rotation. It consists of rotating blades that move along with the propeller and cuts the objects entangled around the propeller.
