Netherlands-based MarQuip has created a custom solution for smaller yachts to meet the challenges of the IMO Tier III requirements that will come into force in 2021.
The IMO Tier III regulations regarding nitrogen oxide (NOx) emissions have already taken effect for all large vessels with an engine output of 130 kW or more, and which had their keel-laying on or after Jan. 1, 2016. The regulations specify that NOx emissions must be, at most, around 70% lower than the maximum under the Tier II regulations.
From 2021, these same regulations will come into force for all yachts more than 78 feet (24m), no matter their volume. Simply tuning the engine will not be sufficient to reduce emissions in most cases, and smaller yachts create a particular challenge as smaller boats are subject to constraints of size and space.
Where large yachts have used after-treatment units that are heavy and bulky, the smaller engine rooms on yachts under 500GT require an alternate solution.
Marquip has developed a custom solution for small yachts – the most compact system for yachts under 500GT or 164 feet (50m), according to a company press release. This compact, custom IMO Tier III exhaust system was developed by integrating its water-injection system inside the SCR/silencer unit. The system comes ready for installation and carries MarQuip’s ISO14001:2015 certification, meeting the highest standards of environmental management.
