At a research facility in Copenhagen, a unique ship’s engine has been developed. Powered by both diesel and liquefied natural gas, it has been designed to reduce the emissions of gases like carbon dioxide and nitrogen oxides.
Its performance differs little from normal diesel engines, say the scientists involved in this European research project
.
“Ship operators will have extra screens to monitor on the operation panel. The only extra function that they will have to take care of is to press gas when desired,” says Michael Johnsen Kryger, a mechanical engineer with MAN Diesel & Turbo.
The biggest challenge was to develop components from new materials that would still be safe and reliable, says Kryger: “The gas is under pressure of about 300 bars. And we have a double wall system consisting of an inner pipe and an outer pipe. The outer pipe is ventilated and we are monitoring the flow, and we are monitoring the gas so we are able to see if there is any gas leakages in the syst
