Jan De Nul Group’s new Trailing Suction Hopper Dredgers, Sanderus, Ortelius, Tristão Da Cunha, Afonso De Albuquerque, Diogo Cão have become the first ships to receive the new BV notation recognizing the performance of ultra-low emission vessels (ULEvs).
The Jan De Nul units are specifically designed for ultra-low emissions, including installation of a two-stage catalytic filter system.
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. The voluntary notation can be assigned to ships that exceed existing MARPOL requirements for lowering pollutant emissions.
Originally developed for internal combustion engines for non-road mobile machinery – including inland vessels – Bureau Veritas’ experts have reworked the existing requirements to develop a set of standards for seagoing ships.
The Bureau Veritas additional class notation ULEv (for Ultra-Low Emission Vessel) 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,
…said Patrick Jan, Product Manager at Bureau Veritas Marine & Offshore.
Jan De Nul designs its latest vessels fitted with a highly advanced exhaust gas filtering system by means of a Selective Catalytic Reduction (SCR) system and a Diesel Particulate Filter (DPF).
As well as design solutions, Jan De Nul Group is adopting 100% renewable fuel, as a certified sustainable substitute for fossil fuel made from waste flows. Since the end of 2019, its first Trailing Suction Hopper Dredger in Zeebrugge has been operating on 100% biofuel. Jan De Nul Group is considering this switch for other dredging vessels.
Air pollution is one of the biggest dangers to public health. Marine construction activities are mostly situated in the vicinity of coastlines, ports and harbours, and densely populated areas. Even if the dredging industry accounts for only 0.1% of the total emission of global shipping traffic, we feel personally involved in this issue and regard it as one of our core missions to do something about it,
…stressed Michel Deruyck, Head of Energy at Jan De Nul Group.
