Marine Engine Overhaul Cost & Downtime Tool

Estimate engine-overhaul labor, parts, specialists, workshop costs, logistics, contingency and the commercial value of downtime. Advanced mode builds the estimate from individual work packages, calculates average workforce requirements and compares overhaul exposure with an optional engine replacement scenario.

Technical Overhaul Cost
Labor, spares, specialists, machining, logistics and contingency
Downtime Exposure
Planned days plus probability-weighted delay and lost vessel contribution
Repair vs Replace
Optional advanced comparison using total economic exposure and future running hours

Engine & Overhaul Scope

Enter your own project assumptions. Costs vary materially by engine, scope, condition, location, access and OEM requirements.

Engine Overhaul Results

Simple overhaul and downtime estimate

Enter engine data
Enter engine power and overhaul assumptions to calculate technical cost, expected downtime and total economic exposure.
Planning estimate only. Actual engine-overhaul cost and duration depend on engine model, running hours, measured condition, inspection findings, access, removals, spare-part availability, OEM requirements, workshop capability, vessel location, class requirements, hot-work controls, lifting arrangements and concurrent yard work. Work-package sample values are illustrative and should be replaced with vessel-specific quotations, service reports or maintenance planning data. This tool does not determine whether an engine is safe to continue operating, whether overhaul intervals may be extended or whether replacement is technically appropriate.
