DNV GL announces new emission reduction notation

Classification society DNV GL has announced a new class notation for exhaust gas cleaning systems (EGCS). The new notation, Emission reduction (ER), will cover scrubbers for removing SOx, selective catalytic reduction (SCR)m and exhaust gas recirculation (EGR) systems for removing NOx. The new notation will be published in July 2018, DNV GL said at Posidonia 2018 last week.

Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime, said that “as the 2020 IMO sulphur cap on fuel draws closer, we have been hearing more and more from ship owners and operators who are looking for guidance on the installation and approval of systems which reduce emissions to air. Therefore, we are very pleased to be able to offer the Emission reduction notation to our customers. This notation will enhance the transparency of the installation and approval process for owners, the yards, and class, and give owners the confidence to invest in these systems.”

He noted that the interest in installing emission reductions systems, especially scrubbers, had risen dramatically in recent months. In May 2018, the total number of vessels either ordered or installed with scrubbers stood at 817.

Stine Mundal, Head of Section for Environmental Certification at DNV GL – Maritime, noted that “bulk and container vessels are the segments with the most installations, overtaking cruise vessels, which had been the early adopters. This indicates that owners are making their solution decisions now and many are choosing scrubbers to comply with emissions restrictions.”

The class notation sets out requirements for the design and arrangement of EGCS, SCR and EGR systems, including the piping systems conveying wash water and/or treatment fluids, the exhaust arrangements and components, control, monitoring and safety systems as well as manufacture, workmanship and testing.
