Jan de Nul dredgers first to secure BV ultra-low emissions notation

Five of the company’s trailing suction hopper dredgers have become the first ships to receive Bureau Veritas’s new ultra-low emission vessels (ULEVs) notation.

The dredgers – Sanderus, Ortelius, Tristao da Cuhna, Alfonso de Albuquerque and Diogo Cao – are specifically designed for ultra-low emissions, including the installation of a two-stage catalytic filter system.

The new notation can be assigned to ships that exceed existing MARPOL requirements for lowering pollutant emissions. The voluntary notation accounts for air quality, including hydrocarbons, carbon, NOx, and particulate matter, as well as particle numbers.

Patrick Jan, Product Manager at Bureau Veritas Marine & Offshore, commented: ‘The Bureau Veritas additional class notation ULEV is the most advanced set of requirements regarding the capacity of a ship to emit gaseous pollutants and particular pollutants at a very low level. It is certainly a significant milestone on the path to reducing maritime environmental impact.’

First published in 2019, Bureau Veritas developed the ULEV notation by adapting the European Commission’s Stage V policy for emissions reduction to the specific needs of sea-going vessels. Originally developed for internal combustion engines for non-road mobile machinery – including inland vessels – the class society has reworked the existing requirements to develop a set of standards for seagoing ships.

Jan De Nul Group is also using 100% renewable fuel, as a certified sustainable substitute for fossil fuel made from waste flows. Its first trailing suction hopper dredger in Zeebrugge has been operating on 100% biofuel since the end of 2019 and the company says it is considering this switch for other dredging vessels.
