Ultra-Low Emission Vessel Ortelius Joins Jan De Nul Fleet

The Singaporean shipyard Keppel Offshore & Marine Ltd., successfully delivered the 6,000 m3 Trailing Suction Hopper Dredger Ortelius to Jan De Nul Group. This vessel is an identical copy of the Ultra-Low Emission vessel Sanderus, in service since February 2020 and currently at work on the River Scheldt in Belgium.


Ortelius is the fifth dredger delivered by Keppel O&M to Jan De Nul Group, following the delivery of three 3,500 m3Trailing Suction Hoppers Dredgers (TSHD) and one 6,000 m3 TSHD, the Sanderus. All five are Ultra-Low Emission vessels (ULEv), equipped with a two-stage catalytic filter system.

Built to the requirements of the EU Stage V and International Maritime Organization's (IMO) Tier III regulations, Ortelius is diesel-electric driven and able to dredge to a maximum depth of 35 m. It features a shallow draught, is highly maneuverable, and suitable for working in confined areas.

Mr. Robby De Backer, Director of Newbuilding Department of Jan De Nul Group: "Ortelius, like all our new dredgers showcases the capabilities of dredging at the lowest levels of emissions to date. Our teams closely worked with the Keppel teams to overcome the challenges caused by COVID-19 and expedite the delivery of Ortelius. We are proud to partner with industry leader Keppel, who has, through their engineering expertise and excellent service, provided assurance in the safe delivery of high-quality vessels.”

Mr. Tan Leong Peng, Managing Director (New Builds) of Keppel O&M: "The delivery of a fifth dredger is testament to Keppel O&M’s newbuild capabilities and technological expertise. Our partnership with Jan De Nul has grown from strength to strength, and we were able to deliver all five Ultra-Low Emission dredgers to them safely and efficiently as a result of a holistic construction methodology. In dealing with COVID-19, we have put in place safe management measures, optimized operations and diversified our supply chain network, enabling us to catch up on work in a safe and efficient manner.”

A Sustainable Dredger Focusing on Better Air Quality

Internal combustion engines without post-treatment emit air pollution affecting both climate and air quality. Air pollution and particulate matter damage our health and also have a direct impact on our living environment.

With its Ultra-Low Emission vessels, Jan De Nul Group aims for much better air quality. These vessels are equipped with a catalyst that renders nitrogen oxides harmless and with a soot filter blocking the finest particles. Several of these pollutants also affect our climate so that the post-treatment also ensures a reduction of greenhouse gases.

The newest generation of Jan De Nul vessels is fitted with this highly advanced dual exhaust gas filter system, making Jan De Nul a frontrunner within global shipping.
