Building the large LNG terminals to get gas in its liquid form from Canada, the US and Qatar, is essential for Europe as it is expected that Russia will cut off gas supplies this winter. Germany needs three large LNG terminals on the Baltic Sea. About 1.6 million tons of weapons and explosives were dumped into the North Sea and Baltic Sea after World War II. The problem is most acute near Germany as Allied Commanders ordered the destruction of German explosives after the war. All this debris has to be removed before LNG terminals or offshore windfarms can be built as shown in this report in WSJ.
