Objective
To minimize unplanned engine downtime and reduce overhaul-related maintenance costs by adopting a data-driven, condition-based monitoring approach.
Challenge / Problem Context
Customer needed to eliminate unplanned engine downtime through accurate health diagnostics.
OEM recommended a Top Overhaul of Niigata Engine (TOH) at 12,000 running hours, leading to high maintenance costs.
Lack of real-time data limited visibility into actual engine condition.
What Did We Do?
Proposed the implementation of a real-time Engine Condition Monitoring System to continuously track engine health parameters.
Enabled both onboard and onshore teams to access live engine condition data, ensuring 24/7 visibility and control.
Designed a customized real-time dashboard tailored to the customer’s operational needs and preferences.
Guided the customer to perform only the necessary cylinder-specific maintenance (injectors, bearings, fuel injection pumps), based on actual engine data.
Achieved over 6,000 running hours and 12 months of continuous monitoring without unplanned downtime.
Results That We Achieved
Eliminated one complete TOH, saving $60,000 in spares and service costs.
Reduced major overhaul (MOH) spare costs to $148,000 from $547,000, resulting in 73% cost savings.
Prevented 15 days of vessel downtime, improving revenue generation and asset uptime.
Empowered office-based teams to remotely monitor and manage engine health in real time.
