Damen Marine NOx Reduction System

Sustainable maritime solutions

Damen’s work on the electrification of the maritime industry falls under the so-called E3 umbrella. That is, environmentally friendly, efficient in operation and economically viable. The shipyards group is currently working on a number of projects for electric vessels.

Tackling emissions head on

IMO Tier III

Vessels for the future

With Damen’s goal of becoming the most sustainable shipbuilder in the world, IMO Tier III represents an opportunity to support the advance of environmentally conscious shipping. All vessels entering the US & Caribbean (keels from 2016) and the North Sea and Baltic (2021 onwards) must comply with the new regulation.

Advanced systems

Suited to all extremes

The Damen Marine NOx Reduction System is an advanced active emissions control system using selective catalytic reduction (SCR) technology suited for diesel marine engines. We have designed the system to operate on both high and low loads in ambient conditions from -30 degrees C up to 45 degrees C.

Explore the SCR system

Proven innovation

All of our Next Generation Tugs are designed to be compatible with the Damen Marine NOx Reduction System, which can be fitted – or retrofitted – at any time. Damen’s well-known standardisation strategy gives our clients fast access to a proven, modular system.

In-house solution

In order to be ready for the new rules, Damen began development of an emissions reduction system for its tugs some years ago. The result was the in-house design and development of a class-approved solution; the Damen NOx reduction System. A system that reduces the NOx emissions of a tug some 80% compared with IMO Tier II requirements.

NOx and noise reduction

It wasn’t without its challenges, technical ones for sure, but also the relative lack of space in a compact vessel such as a tug. We got around that by combining the system with the tug’s silencers – reducing not only NOx emissions, but noise levels at the same time.

Strong as steel

The Damen Marine NOx Reduction System uses a catalyst to react with urea to chemically reduce NOx emissions. To ensure its suitability for urea, the system uses stainless steel for its tanks, transfer pump and piping.

Connecting to the cloud

The SCR system can be integrated with the remote monitoring IoT platform Damen Triton. Connected in this way, the operator can continuously monitor the system to control and optimise cleaning efficiency and to control ammonia slip.

Easily fitted & retrofitted

The modular and compact standardised system can be fitted – or retrofitted – to Damen vessels old and new. In fact, the modularity of the system, combined with the design’s certification for use with multiple types of engine, means it can often be installed to non-Damen vessels too.

Meet Damen’s Tugs

Different jobs need different tugs. Each family of tug – ASDs, RSDs or Stan Tugs – are prepared for IMO Tier III. We focus on safety, sustainability, reliability and efficiency.
