Non-Invasive Diagnostics Help The Tug Owner Extends Overhaul Intervals on 7 Vessels by Targeting Key Injector Fixes.
Background
Equipment
Niigata engines
Vessel
Habour tug
Solution
Engine Condition Monitoring System
Customer
Habour Tug Operator In India
CHALLENGE
- 7 vessels were due for a major overhaul as per OEM’s maintenance cycle at 24,000 running hours which would have cost the customer $2,50,000
- Along with the cost this major overhaul would have cost the customer about 18-20 days of downtime for each vessel, resulting in loss of revenue
- The life-cycle of each vessel is around 20 years, approximately 65,000 running hours, meaning 2 MOH have to be performed for each vessel before it’s scrapped.
SOLUTION
- The Customer deployed Neptunus’ engine condition monitoring system (part of Neptunus’ Asset Reliability Management solution) on all 14 engines of their 7 tugs for an engine health checkup which was already above 24,000 running hours
- Neptunus did the engine health check without opening up the engine and with the help of 2 sensors only we submitted a conclusive report which indicated to replacing only 2 injectors on a couple of their tugs and they can run further without a major overhaul
- This helped the customer make a confident data-backed decision, replace only the required parts and extend the major overhaul
- With the extension of 1st MOH, the customer is able to eliminate 2nd MOH in life-cycle of these vessels
BENEFITS
- Customer was able to see in-depth report cylinder-specific, do the necessary scope needed at bare minimum cost
- With this approach, the customer is able to eliminate 2nd MOH thus resulting in huge savings of $1,00,000 for each vessels
