How do Wärtsilä spare parts help keep my vessel compliant?

Every owner and operator in the marine sector is accountable for their engines being emission-compliant after repair or maintenance. Using a non-OEM part could mean your engine is not compliant. Not all parts labelled as OEM parts are genuine, and thus compliant either. Using non-compliant parts can lead to fines, lost business and damage to your reputation.

Choosing genuine, high-quality OEM parts from Wärtsilä will eliminate the risk of non-compliance and give you peace of mind because:

  • You will have the equipment builder’s warranty – OEM parts will perform as designed in your engine
  • OEM parts are tested to meet IMO emission standards
  • OEM parts may be less prone to premature wear or deterioration.

But choosing genuine, emission-compliant OEM spare parts is not enough to keep your engine safe and compliant. In fact, it’s just the start. Here are five top tips that will help keep your operations compliant.

Why choose genuine OEM parts from Wärtsilä?

Keep your operations reliable

Genuine OEM parts from Wärtsilä keep your operations reliable because they:

  • perform predictably, so they are safer and eliminate the risk of non-compliance

A longer lifetime

Genuine OEM parts from Wärtsilä can have a considerably longer lifetime compared to a non-OEM part because they:

  • are thoroughly checked and tested to ensure proper fit and performance
