Redeco: marine lantern beacon

Repair marine lantern

PT Redeco Petrolin Utama

Overview

This job restored a marine lantern used as a navigation marker in the operational area of PT Redeco Petrolin Utama. At the first inspection the device was completely dead and gave no light.

The scope covered damage inspection, repair of electrical and electronic components, better casing protection, function testing and reinstallation of the marine lantern on site.

Challenges

The inspection found several faults at the same time:

• The power cable had burned and melted, and caused a short circuit.

• Several LED units had failed and would not light.

• The casing no longer gave good protection against water and moisture.

• The power supply module was faulty and could not supply stable power.

• The device had to run reliably again outdoors in a marine area with high humidity and high corrosion.

Solutions

The team made these repairs to restore the marine lantern:

1. Replaced the burned and short-circuited power cable with a new cable that matches the power needs of the device.

2. Replaced the LED components that had failed or no longer gave light.

3. Repaired the casing and added waterproof material to improve protection against water and moisture.

4. Repaired the power supply module so the output voltage is stable again and can supply all components.

5. Tested the function, checked power supply stability, verified the LED lighting and reinstalled the device on site.

After the repair and testing, the marine lantern works again and gives light as intended.

Lessons learned

The failure did not come from one component. It was a combination of a power cable fault, LED damage, a degraded casing and a failed power supply module. Inspect the whole device, not only the parts that look damaged.

Protection against water, moisture and the marine environment is key to keeping a marine lantern reliable. Regular checks of the cables, electrical connections, casing seals, power supply module and LED light intensity can find damage early and lower the risk of a complete failure.
