Equipment

Niigata Engine

CHALLENGE

  • Neptunus was assigned a Top Overhaul (ToH) service for a tug boat on its two main engines on a twin screw vessel

SOLUTION

  • Before the Top Overhaul, as a standard practice, Neptunus carried out a detailed health-check of both engines employing our cutting-edge vibration condition monitoring tool under Neptunus’ Asset Reliability Management solution (ARMs). While the starboard side engine showed healthy condition, the port side engine clearly showed poor condition of all the bearings with high mechanical stresses
  • It must be noted that all parameters on the engine were normal
  • Our assessment was that high mechanical stresses coupled with a uniform deteriorated condition of all bearings was an indication of an external issue.
  • Further investigations revealed minor damages to the tips of the port side propeller (possibly by impact of a floating log as was later confirmed by the customer team) causing the propeller to go out of balance. The out of balance propeller was the cause of bearing alerts in our system
  • Based on the findings, the customer repaired the damaged propeller, our system thereafter showed bearings in healthy condition.
  • No intervention was required on the engine.

BENEFITS

  • The engine monitoring system pinpointed the fault at a very early stage after initiation thus optimized scope of the maintenance reduced the vessel  downtime by more than 50%
  • Savings due to preventing intervention on the engine were estimated to be ~USD 14,000.
  • Deferment of ToH based on scientific data helped improve the cash flows of the asset.Deferment of ToH based on scientific data helped improve the cash flows of the asset.
  • The timely servicing of the faulty bearing meant avoiding a possible engine breakdown and saved the engine/Z-peller from getting damaged and going out of service causing loss of revenue. The consequential expenses of drydocking & repairs saved would have been ~ USD 30,000
