Standardized Overhaul: Consistency is King

An overhaul is a critical lifecycle event that’s essential for supporting peak reliability, safety, and maximum uptime. Our globally standardized processes — backed by OEM knowledge, specialized tooling, and comprehensive documentation — replaces uncertainty and complexity with operational predictability and longevity. No matter where you are in the world, you get the same level of expertise and overall procedural standards. Because when it comes to your operation, peace-of-mind is a valuable asset.

 
 
 
 

Overhaul Smarter, Not Harder

 

A standardized overhaul provides several valuable benefits
to help set your operation up for success.

 


 

of

Reliable Performance

of

Predictable Planning & Budgets

of

Cost Efficiency

of

Transparency & Clarity

of

Peace of Mind

of

Digital Support Tools

 
 
 
 
 
 

The Overhaul Process Breakdown
 

of


Forecast & Planning

Maintenance needs are typically identified based on operating hours or equipment condition. Dealers or Territory Sales Manager (TSM) then proactively contact the customer, assess the required scope, and enter a forecast into the system.

 

of


Parts & ResourcePreparation

The OEM parts package is assembled based on maintenance catalogs according to your application. Technicians and certified tools are then scheduled accordingly.

 

of


Overhaul Execution
(Workshop or Onsite)

The service is carried out either in our workshop or on-site, depending on customer preference with the former being more cost-efficient and the latter more timely. Technicians then take steps to follow the standardized job cards, which specify exactly what needs to be done.

 


of


Handling the Unexpected

Unexpected issues are handled with flexibility and urgency, utilizing access to local warehouses or escalation to customer service and legal teams.

 

of


Component Analysis & Recommendations

Parts are removed for analysis to identify wear patterns and provide suggestion on replacement, repair or operational improvement

 

of


Documentation& Follow‑Up
(Workshop or Onsite)

Service reports and digital evaluations ensure transparency and traceability. Targeted repairs take place when necessary while modular contracts and remanufactured options provide cost efficiency without compromising quality.

Frequently Asked Questions

Engine optimization is a tailored upgrade package that combines the technical solution, required spare parts, and compliance support for your specific engine and operating profile. Depending on your needs, upgrades can include retrofit kits—such as updated injection systems, emissions solutions like SCR for NOx reduction, methanol direct injection for CO₂ reduction, and software/controls updates—plus options for digital connectivity and guidance on meeting IMO regulations and class requirements.

We start with your operational goals—fuel savings, compliance, image—and constraints like vessel type, operating profile, and regulatory environment. Our teams then evaluate your engine and use simulation and thermodynamic analysis to recommend a solution that fits your case and budget, giving you a practical path to performance, compliance, and efficiency.

Upgrade kits are designed to be compatible with engines in the field, so all projects do not require a full engine replacement. Installations are planned for manageable effort and minimized downtime. The exact scope and timeline will be determined following an on-site evaluation of your engine configuration.

Yes. Our solutions—SCR Technology, IMO Tier II upgrade, Methanol/ Ethanol direct injection, and more—are engineered to reduce emissions and developed with future regulatory readiness in mind, so you can operate confidently today while preparing for tomorrow.

Every upgrade is verified by our engineering: combustion simulation, thermodynamic analysis, and software-controlled engine management (injection system, turbocharger, control units). Solutions are validated on our test beds under real and extreme conditions, and continuously improved using field data across the product lifecycle.
