W\u00e4rtsil\u00e4, a technology group, has created an ultra-low emissions <\/p>\n

version of its W\u00e4rtsil\u00e4 31DF engine that can reportedly reduce methane emissions <\/p>\n

by 41 per cent.<\/strong><\/p>\n

\"W\u00e4rtsil\u00e4<\/p>\n

When running on LNG, this improved version may reduce methane emissions by <\/p>\n

up to 56 per cent and nitrogen oxide (NOx) emissions by up to 86 per cent at 50 <\/p>\n

per cent load.<\/p>\n

<\/p>\n

The new version of W\u00e4rtsil\u00e4 31DF engine , which is used on one of <\/p>\n

Wasaline\u2019s four engines on the Aurora Botnia ferry, has reportedly helped the <\/p>\n

Finnish-Swedish ferry operator decrease methane emissions by 10 per cent.<\/p>\n

<\/p>\n

As part of the EU co-funded Green Ray and SeaTech projects, W\u00e4rtsil\u00e4 <\/p>\n

piloted the ultra-low emissions concept onboard the Aurora Botnia with <\/p>\n

reportedly good results verified through an independent study conducted in <\/p>\n

December 2022 by VTT, the Technical Research Centre of Finland.<\/p>\n

<\/p>\n

Encouraged by the encouraging findings, W\u00e4rtsil\u00e4 has now commercialised the <\/p>\n

new ultra-low emissions variant of the W\u00e4rtsil\u00e4 31DF engine.<\/p>\n

<\/p>\n

This newest cooperation is part of W\u00e4rtsil\u00e4 and Wasaline\u2019s long-term <\/p>\n

commitment to minimise emissions on the Aurora Botnia, the world\u2019s most <\/p>\n

ecologically efficient RoPax ferry.<\/p>\n

<\/p>\n

Peter St\u00e5hlberg, Managing Director of Wasaline, commented: \u201cWe are very <\/p>\n

committed to decarbonisation, and we have worked closely with W\u00e4rtsil\u00e4 to make <\/p>\n

sustainable shipping a reality. It is a goal-oriented partnership that benefits <\/p>\n

both companies, as well as the industry as a whole.<\/p>\n

<\/p>\n

\u201cWe have been pleased to allow the \u2018Aurora Botnia\u2019 to be utilised as a <\/p>\n

floating laboratory, and we are excited to see the success of this latest <\/p>\n

W\u00e4rtsil\u00e4 technology breakthrough.\u201d<\/p>\n

<\/p>\n

The W\u00e4rtsil\u00e4 31DF engine platform, which was introduced in 2015, already <\/p>\n

satisfies current regulatory requirements. The new version will allow operators <\/p>\n

to go even farther in decreasing methane emissions, helping to futureproof their <\/p>\n

vessels against possibly stricter worldwide standards in the long run.<\/p>\n

<\/p>\n

Furthermore, upgrading dual fuel technology to reduce methane emissions <\/p>\n

will have a significant influence on LNG\u2019s long-term viability as a maritime <\/p>\n

fuel.<\/p>\n

<\/p>\n

Stefan Nysj\u00f6, Vice President of Power Supply, W\u00e4rtsil\u00e4 Marine Power, said: <\/p>\n

\u201cOur work around reducing methane slip and GHG emissions is part of W\u00e4rtsil\u00e4\u2019s <\/p>\n

effort to continuously improve efficiency and reduce emissions of our products, <\/p>\n

and this new innovation is one more very important step along the road to <\/p>\n

decarbonisation.<\/p>\n

<\/p>\n

\u201cThe building of an LNG fuel infrastructure has been an important factor in <\/p>\n

shipping\u2019s transition towards cleaner operations, and W\u00e4rtsil\u00e4 continues to <\/p>\n

create solutions that support this journey. Our focus has always been to improve <\/p>\n

and optimise existing solutions, and to develop exciting new ones. With this <\/p>\n

latest introduction, we are clearly delivering on this commitment.\u201d<\/p>\n

<\/p>\n

Although methane slip from engines is minor in percentage terms, it is <\/p>\n

substantially more effective than CO2 \u2013 up to 28 times more toxic.<\/p>\n

<\/p>\n

Cutting methane emissions is one of the most effective approaches for the <\/p>\n

shipping sector to reduce overall greenhouse gas (GHG) emissions from engines <\/p>\n

over the next ten years, complementing other initiatives to reduce CO2 <\/p>\n

emissions.<\/p>\n

<\/p>\n

In September, W\u00e4rtsil\u00e4 announced it will supply an integrated hybrid <\/p>\n

propulsion system for two new hybrid RoRo vessels.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
