Summary

  Wärtsilä has a wide variety of solutions available for environmental compliance, both for new builds and existing vessels.

  In SOx Emission Control Areas the cost savings using scrubber are immediate. In 2015 the cost savings will be dramatic.

  In global operation outside SECA drastic savings in 2020 are evident with scrubber. Already from 2012 savings are possible when using cheaper HFO with higher sulphur content than the global limit 3.5 %, where available.

  In ports with stringent sulphur limits (e.g. EU) savings can already be achieved with scrubbers for diesel-generators and oil-fired boilers.

  Wärtsilä fresh water scrubber solutions are fit for new builds and retrofits, for any engine and boiler brand.
