An Oldendorff Carriers bulker is being repaired after suffering engine failure in Singapore.
The company told TradeWinds that work on the 209,000-dwt Helena Oldendorff (built 2016) is expected to be completed soon.
Pressure group Environmental Protection Alliance (EPA) had earlier claimed the scrubber system failed and flooded the engine.
Oldendorff did not confirm this but said: "As scrubbers are not required until January 1, 2020, a scrubber failure now would not delay the vessel.
"The vessel is loaded and on its way from Brazil to China. It is expected to sail from Singapore next week."
The company added: "The scrubber systems that Oldendorff Carriers has fitted on our vessels are working well. We are achieving sulphur emissions well below the emissions of 0.5% compliant fuel required by IMO 2020."
