<p>[quote user="M636C"]But I understand that turbine powered ships are allowed in European ports where diesel ships are actively discouraged through emission regulations.[/quote]</p> <p>It would interesting to know where such information can be found.</p> <p>Shipping emissing regulations come from Marpol. Currently on the oceans usually Heavy Fuel Oil (a residue) is burnt. The sulphur content is currently limited to 3.5%. Than there are Emission Control Zones: Baltic Sea, North Sea, North American coast etc. Here 0.1% are allowed. Than there are NOx standards higher in the USA than in Europe thar require use Marine Diesel Oil.</p> <p>Does that means discouraging? There are so many countries involved that it has no influence on shipping. With the huge overcapacities in the container shipping market the ECA emission standard had only very limited influence on prices.</p> <p>The 20,000 TEU container ships going to European port have engine output of 100,000 bhp, not easy to obtain with turbines. I know of a few warships having turbines but the last mearchant vessel that comes to mind was the Finnjet (1977-2008). Turbines need high quality fuel and can't compete with HFO fueled diesel engines.<br />Regards, Volker</p>
