18-Month Fleetwide Optimization

From reactive repairs to strategic maintenance

A global fleet operator approached MARITECH after facing persistent issues across their vessels’ plate heat exchangers. Rising maintenance costs, reduced thermal efficiency, and frequent failures were disrupting operations. The fleet’s mix of OEM systems, irregular servicing, and absence of a preventive maintenance plan made the situation increasingly unsustainable.

Our Solution
MARITECH deployed a structured, lifecycle-oriented strategy across the client’s vessels:
• Fleetwide diagnostics to benchmark actual PHE condition and prioritize service needs
• Workshop reconditioning using our 10-step process: plate testing, proper re-gasketing, and pressure validation
• Cross-brand expertise applied to standardize quality across different OEMs
• Tailored preventive maintenance plan, including onboard crew routines, service tracking, and spare optimization

The Results
✅ 32% drop in annual PHE-related service costs
✅ 40% longer gasket life across high-temp units
✅ Zero unplanned shutdowns in 12 months
✅ Unified service methodology across fleet, for all units

Client Insight
“MARITECH brought structure and predictability into an area that was once chaotic. Their consistency across brands made a real difference.”
