Upgrades & Agreements

Ahead of the compliance curve

At Wärtsilä Exhaust Treatment, we know that a scrubber is a considerable investment for the long term. That is why we are committed to constantly upgrade and improve our solutions in line with the latest and best available technology, as well as to meet customer and market demands.

A Wärtsilä exhaust gas treatment system ensures you stay ahead of the compliance curve, providing a solution ahead of IMO action on shipping emissions. And as part of this, Wärtsilä continually explores ways of making scrubbers more affordable to ensure further strong uptake across the market. 

When they are ready, we want to get these upgrades where they matter: into the hands of owners and operators and the vessels using our systems. That is why we commit to work with all our customers to continuously upgrade our exhaust gas treatment systems.

Ensuring uptime of your exhaust gas treatment system means saving money. Wärtsilä is committed to finding a maintenance agreement solution that suits our customers' needs. 


Key benefits with a Wärtsilä Agreement

  • Get scrubber system related maintenance, OEM spare parts and consumables – anytime, anywhere.
  • Support you to operate the scrubber systems according to your Onboard Monitoring Manual.
  • Get an overview of your fleet and insights into from a  fuel efficiency and emissions perspective.
  • Control maintenance costs while ensuring service levels
  • Ensure long-term cost predictability.
  • Maximise uptime through optimised maintenance.
  • Ensure global coordination through network companies with workshops and skilled service experts.
  • Receive technical advice on system status, technical developments and optimization options based on hands-on experience from your scrubber system.

Regular maintenance by a trained professional and cyclic training of crew would have prevented the exhaust gas analyser failure from happening or it would have given the vessel time to react on corrective actions before the sudden failure occurred.

Upgrade to meet new regulations

For many shipowners and operators, it will be relevant to upgrade their systems to meet new regulations and to save operating costs. Read more about some of our most frequent upgrades.

Expert insight for scrubbers - Predictive maintenance

Expert Insight for Scrubbers is a smart service provided by Wärtsilä for optimising SOx scrubber operation. Through continuous fleet-wide tracking of vessel compliance and scrubber utilization, we help our customers get the most out of their systems. The service provides dashboards and performance indicators through an online tool, Wärtsilä’s Collaboration App, which delivers insight on how to get the most out of your Exhaust Gas Treatment system.

Two-way communication features, allowing Wärtsilä engineers to troubleshoot and provide assistance to crew remotely.

Machine Learning fault detection systems can detect anomalies at a much earlier stage than traditional service can, giving the ship owners the ability to plan for unscheduled maintenance and avoid unwanted downtime of the scrubber system.

These are features we’ve already rolled out for our engine portfolio, and we look forward to bringing these experiences, and expertise, to our scrubbers as well.

The future of adaptive scrubber operations, today

Wärtsilä’s Eco-Controller enables dynamic water flows, increasing the flexibility of your scrubber’s operation, and ultimately optimising its energy consumption. This is a simple, hardware-free upgrade that has a huge proportional efficiency impact.

And it doesn’t stop there: our Eco-Controller includes real time instantaneous power usage and over time energy consumption data for fully transparent performance.

Water treatment system upgrade

Do you have a Wärtsilä closed loop or hybrid scrubber system installed? The closed loop water treatment system is an important part of the technology’s overall operation. That’s why we have several solutions to make sure you’re operating the system that suits your vessel or fleet’s requirements.

Soot and ash from the exhaust gas is captured in the scrubbing water and the closed loop wash water treatment system ensures an effluent quality that meets various worldwide wash water regulations and restrictions. Our portfolio of closed loop water treatment systems is easy to operate with a small onboard footprint, low power consumption and low sludge waste production.

Deplume upgrade

Did you know that when a scrubber is installed, most of the smoke coming from the exhaust gas outlet is pure water vapour? However, appearance matters. Despite the relative lack of pollutants in the visible exhaust gas, we understand that “more smoke” often feels like “more pollution”.

A deplume system can solve this challenge. By heating up the vapour, particles become diluted and are therefore less visible. For vessels in port, in a fjord, or sailing with passengers, reducing visible smoke can be very important to your operations.

We can generally install deplume systems at a yard, and in five to six days, depending on the number of scrubbers installed and access to these existing technologies.

Alkali upgrade

Did you know that caustic soda (sodium hydroxide or NaOH) isn’t the only alkali available for closed loop mode operation? Another viable alternative is magnesium hydroxide (Mg (OH)2). Because of the different chemical and physical properties between them, some hardware and software changes are required to make the switch, though. As a result, we’ve developed an alkali upgrade concept that will make the switch to magnesium hydroxide a breeze.

But why would one want to do such a switch? As it happens, there are a few good reasons. Magnesium hydroxide is non-hazardous and can even be cheaper than sodium hydroxide.
