Attend to Vessel at Singapore anchorage.
Inspection of Inert gas’s cooling tower
- Found that Inert gas’s cooling tower is impossible to remove vertically from the top, because the Nitrogen generator room was located right above to it.
- Some measurement made, we recommend removing the wall at the exit door so that the Inert gas’s cooling tower can remove horizontally from the side.
- Understand that the vessel will be going for dry docking next year. So we suggest that this work to be carry out during dry dock, as it is a big project and also time consuming.

- Overhaul all the 9 pcs. of actuators.
- Overhaul the Positioner for the Capacity’s valve and ATM‘s valve.
- Calibration for the O2 Analyzer.
- Calibration the control circuit and commissioning for the system.
- Change the Ignition transformer.
- If the Ignition Burner is bad, renew it to the remove able type.
