Why do lifecycle services matter for exhaust treatment solutions?

Compliance

Regulatory pressures from IMO make it essential to maintain scrubbers proactively. Keeping scrubbers in top condition helps you stay aligned with the tightening global and regional rules.

Cost control

Unplanned downtime and emergency repairs can be expensive. Lifecycle services help ensure that your scrubbers are in prime condition, and this reduces the risk of costly non-compliance, too. Predictable OPEX helps when making long-term plans.

Reliability

Scrubber systems are critical for uninterrupted operations. Regular servicing and upgrades prevent failures, safeguard compliance, and keep your vessels trading without costly delays or detentions.

Scrubbers and your decarbonisation journey

Wärtsilä promotes a three-level approach to the maritime decarbonisation journey:

Making operations more efficient

Choosing solutions that help improve the efficiency of the vessel’s operations.

Adopting and using alternative energy sources

Choosing engine technology which runs or has the capability to run on alternative fuels.

Cleaning up emissions

If a vessel cannot run on alternative fuels, the smart choice is to clean up emissions.

  • Exhaust Gas Cleaning (EGC) or scrubbers acting on SOx
  • Wet Electro-Static Precipitators (WESPs) acting on particulate emissions
  • Exhaust Gas Recycling (EGR) or Selective Catalytic Reduction (SCR) acting on NOx  
  • Carbon Capture and Storage (CCS) solutions acting on CO2 

Flexible lifecycle support, long-term value 

Choose the services you need, when you need them: Individual scrubber services are available for you to choose based on your vessel’s operational profile and maintenance schedule. From spare parts and field support to compliance checks and upgrades, you can get expert help when it matters most.

The smart choice for services: While individual services give you flexibility, a tailored Wärtsilä service agreement  will deliver long-term value and peace of mind. You get predictable costs, a dedicated support team and vessel- or fleet-wide insights – all backed by decades of expertise with various scrubber systems.
