RATING PHILOSOPHY
We are working hard to meet and even exceed the increasing
demands of ship owners and operators for cost-effective and
eco-friendly solutions. One example is the engine TBO (Time
Between Overhauls) which we optimize on the basis of field
data analysis and close inspection of engines and components
that have already proven their reliability in field operation.
Depending on the analysis results, we extend maintenance and
TBO intervals keeping safe operation assured.
