Amels 188 Tier III engine test

Dutch shipyard Amels has announced it has reached the final milestone in its 18-month Tier III engineering programme. The yachtbuilder says it has managed to slash NOx emissions by almost 80%.

This custom engineering project reduces the environmental impact of the new 57.7 metre Amels 188 superyacht with little impact to the guest and crew experience onboard.

Amels claims to be the first in the Netherlands to meet Tier III levels following main engine tests last week and generator set tests at the end of last year.

Under stringent new regulations developed by the International Maritime Organization (IMO), large new motoryachts over 500 gross tonnes with a global cruising area must drastically reduce the NOx emissions in their engine exhaust gases.

The shipyard notes that when IMO clarified the deadline for the Tier III limits, the company realised that the industry had no available integrated solution and very limited practical knowhow.

“So we took the lead to ensure there would be no delays for our clients, no compromise on luxury space, and no compromise on our renowned low levels of noise and vibrations. And I believe we’re doing our part to face up to these technical challenges and reduce the environmental impact of our industry. That can only benefit us all,” comments technical director Hans van Triet.

Amels engineered a complete, holistic solution, working together with suppliers to custom engineer components and integrate the MTU 12V4000 M53 diesel engine, HUG Engineering Selective Catalytic Reduction system, silencer and soot filter.

The testing took place under independent Lloyd’s Register class supervision at MTU Benelux.

Further development

The next stage in the Amels 188 development is testing the design’s efficient, fuel-saving technology.

The yacht is the first Amels to feature a hybrid power switchboard with peak shaving (battery bank), a generator set configuration with Amels Smart Power Management (SPM) and AMELS Heat Recovery system.

Amels introduced the 57.7m Amels 188 (970 gross tonnes) at the Monaco Yacht Show 2015. The yacht’s delivery is slated for spring 2018 and Amels says it has already fielded a number of serious enquiries.
