Inspection and documentation
Regular inspection and the associated documentation are essential for reliable operation. We offer inspections both in the workshop and on board of your vessels. In cooperation with you, we prepare a method description, which lists and describes all planned activities in connection with your order.
Prior to overhauls and repairs in the workshop, we can carry out a pre-inspection. This provides information on condition, machining recommendations, and which spare parts we recommend for replacement. It also includes pictorial documentation of recommended repairs and replacements.
Afterwards, the responsible Everllence PrimeServ technician gives you a detailed service report about any completed changes and repairs.
Overhaul to guarantee reliable and efficient operation
With scheduled overhauls, we ensure the best fuel economy of your engine and thus the best possible profitability. This reduces the risk of unforeseen failures, optimizes availability, and ensures reliable operation.
Our ambition is to prevent unnecessary pollution and CO2 emissions, which is why we adhere to the prescribed maintenance intervals.

Retrofits and upgrades for a longer product lifetime
In order to extend the product lifetime and the time between overhauls, reduce CO2 emissions, and increase product performance, we at Everllence, together with our partners, offer retrofit solutions for all product categories. Retrofitting is possible for alternative fuels, such as gas and electricity, but also for diesel.
Popular examples:
- Tier II retrofit: reducing NOx emissions.
- Retrofit of turbochargers
- Upgrading of exhaust gas purification systems
- Upgrading of seals
- Improving the lifetime of valves and valve seats for low-sulfur operation
