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 ...
