CRN, part of the Ferretti Group, has announced that it is the first shipyard in Italy to receive IMO Tier III compliance, for the CRN M/Y 137, a fully custom steel and aluminium 62m megayacht, the yard’s first pleasure vessel to be delivered in early 2020.

In accordance with the regulation, a certified reduction of 70% in harmful emissions of nitrogen oxides (NOx) in engine exhaust gases is now guaranteed for all CRN motoryachts...

In accordance with the regulation, “a certified reduction of 70% in harmful emissions of nitrogen oxides (NOx) in engine exhaust gases is now guaranteed for all CRN motoryachts,” according to a statement from the shipyard.

The project was coordinated and completed by the team of engineers at the CRN Technical Office, and the regulatory compliance was indeed achieved by fitting the engine exhausts with an SCR system, which uses a chemical process to slash harmful emissions.

This makes the new 62m CRN 137, launched last November, the first IMO TIER III–compliant megayacht built in Italy, soon to be followed by another three fully-custom CRN yachts currently under construction: the 62m CRN M/Y 138, 72m CRN M/Y 139 and 60m CRN M/Y 141.

As owners become increasingly environmentally aware, vessels that comply with any kind of regulation seeking to lower harmful emissions will also placate an eco-conscious mind, and therefore appeal to the next generation of potential clients.

While this is a huge success for the Italian shipyard, there is, however, still a lot to be done for smaller vessels who cannot currently accommodate SCR systems...

While this is a huge success for the Italian shipyard, there is, however, still a lot to be done for smaller vessels who cannot currently accommodate SCR systems and are seeking new ways of complying with the imminent regulations.

One of the most pressing topics of conversation within the superyacht industry at present is the IMO Tier III regulations coming into force in less than one year from now, for all vessels under 500gt, over 24m and those that will have had their keel-laying after 1st January 2021.

In our upcoming issue of The Superyacht Shipyard Report, we have spoken to various sectors of the sub-500gt market regarding how ready this part of the superyacht industry is for the impending regulation, the processes currently underway to meet the 2021 deadline, and the impact that these regulations have had thus far.

Vessels over 500gt have had to comply with the IMO Tier III regulations since 2016, and this has been made possible through the installation of Selective Catalytic Reduction systems (SCRs) – an exhaust after-treatment – which works by reducing nitrogen monoxide (NO) and nitrogen dioxide (NO2) to Nitrogen (N2) via the catalyst initiating a reactant added to the exhaust gas mixture. These are large systems put in place within the engine room of a vessel, and thus work well on bigger vessels with ample space, but are yet to be seamlessly integrated into smaller vessels.

A full analysis of the current situation for the sub-500gt sector will be featured in The Superyacht Shipyard Report, available here from the end of March.
