Maintenance

OTRONIX provides Hardware, software technical support and software upgrade service.
Also periodic maintenance and emergency system diagnotic activity can be served by contract.

Maintenance procedure and activity description

Periodic maintenance, monthly regular system check service can be done to prevent system malfunction or trouble. And we are ready to respond to the Emergency call.

Buoy systems

OTRONIX serves buoy manufacturing, mooring, operation status monitoring and maintenance service. Maintenance can be done at site or Otronix buoy manufacturing facility, Donghae.

Buoy system check list
Sensor check & Calibration Comparison sensor data with standard sensors and calibration can be done at the site.
Cable & connector check Cable wearing, short, disconnection can be occur at moving buoys.
Bio-fouling removal Buoys used to be operated as long term monitoring. Bio-fouling can be found any kind of buoy.
System status check Buoy systems work in hot or cold, dry or humid environment with wave motions. Water leakage, corrosion should be avoided.
