T&E launched into the cruise ship MSC World Europa in June 2023 to movie potential methane slip emanating from the ship’s funnels.

We have now put collectively a Q&A to reply among the questions which have been raised following the publication by Bloomberg on July thirty first, 2023, of the article “The invisible local weather affect of a cruise ship” linked to this investigation.

All ships that use an inside combustion engine with LNG let kind of methane escape into the air relying on the engine sort. This contains the 5 Wartsila 4-stroke 14V46DF engines the MSC World Europa is supplied with. The IMO estimates that any such four-stroke, low stress engine lets on common 3.5% of methane escape into the air. The European Union, alternatively, estimates that any such engine lets on common 3.1% methane escape. A number of research have measured CO2 and methane emissions on LNG-powered ships at sea. They estimate that the quantity of methane that slips into the air varies between 2.2% to eight% with a major variability linked to the load.

Learn the briefing to study extra concerning the technical instruments that have been used to recording the methane slips and the way did we decide the accuracy of the photographs.;
