Pioneering fuel saving ducts on Bulk Carriers

21st June 2022

Nearly 50 fuel saving ducts devices have been procured by Oldendorff Carriers over 50 years. We have also started many other initiatives to reduce fuel consumption and emissions, which you can see in the other news stories. The purpose of the fuel saving devices is not only to reduce our fuel consumption but also to reduce our Greenhouse Gas emissions (GHG).

In the early 1980’s, OLDENDORFF CARRIERS was the first dry bulk shipping company to invest in Wake Equalizing Ducts (WED), when we installed “Schneekluth” fuel saving ducts on our 74,000 tdw Panamax newbuildings “Ludolf Oldendorff” and “Helga Oldendorff”.

Many more devices have been added over the years, and last week we ordered Becker “Mewis” ducts and rudder bulbs for another 12 ships (7 Babycapes and 5 Post-panamaxes), which will be installed during first half 2023. In our existing fleet, we will therefore have WED’s installed on the following 45 bulk carriers:

11 x 209,000 tdw eco Newcastlemaxes, built at 3 yards in China

4 x 208,000 tdw eco Newcastlemaxes, built at Hyundai, Korea

7 x 121,000 tdw Babycapes, built at Sinopacific, China

4 x 115,000 tdw Babycapes, built at New Times, China

2 x 115,000 tdw Babycapes, built at Jiangnan, China

1 x 114,000 tdw Babycape, built at Shanghai SY, China

7 x 93,000 tdw Post-panamaxes, built at 3 yards in China

6 x 81,000 tdw Kamsarmaxes, built at Jinling, China

1 x 38,000 tdw Handy, built at Avic, China

2 x 36,000 tdw Handies, built at Samjin, China

This means, that by next year, 45 of our ships will have a Wake Equalizing Duct, which will help achieve better C.I.I. ratings, lower fuel consumption and reduced emissions. In addition, at least 20 of our ships have asymmetric fins, rudder bulbs, boss cap fin propellers and other fuel savings devices.

Furthermore, since 2019, we invested more than US$ 300 Million in Exhaust Gas Cleaning System (EGCS), which abate nearly all of the sulphur oxide emissions. Compared to ships that burn VLSFO without such systems, our ships emit up to 90% less particulate matter and up to 60% less black carbon than ships consuming VLSFO, which leads to much cleaner exhaust at sea and in port.
