Objective

To complete the overhaul of a Kawasaki side thruster engine within a tight deadline, ensuring the vessel remained operational and avoided significant off-hire losses.

Challenge / Problem Context

  • The auxiliary engine was frequently tripping, disrupting Bow Thruster operations critical to vessel maneuverability.
  • Vessel engineers were unable to diagnose or fix the issue onboard.
  • Travel restrictions due to the COVID-19 lockdown prevented Neptunus' service team from attending the vessel physically.
  • Risk of vessel off-hire, potentially leading to a revenue loss of ~$35,000 over 7 days.
  • Additional potential losses included alongside-docking and service deployment charges estimated at ~$2,000.

What Did We Do?

  • We assessed the situation remotely through detailed discussions with the vessel’s engineering team to understand symptoms and previous troubleshooting steps.
  • We created and shared a customized technical checklist guiding the vessel team to systematically investigate potential failure points.
  • We instructed the team to check voltage values immediately after engine restart, flash the exciter if required, verify winding resistance and insulation levels, and perform a detailed visual inspection of the rotating rectifier assembly.
  • We maintained continuous communication to guide the crew through each diagnostic step, ensuring no oversight.
  • Within 12 hours, our remote intervention helped identify the issue-loose bolts on the rotating rectifier assembly-and guided the team to resolve it, leading to restoration of normal engine function.

Results That We Achieved

  • Successfully restored the engine’s normal operation remotely within 12 hours of first contact.
  • Prevented vessel off-hire, thereby saving an estimated revenue loss of ~$35,000.
  • Avoided additional costs of ~$2,000 related to vessel docking and engineer mobilization.
  • Strengthened client trust and demonstrated the effectiveness of Neptunus’ Remote Maintenance Services even under severe constraints.
