The laying of the 1220 km long underwater pipeline from Vyborg in Russia to Greifswald in Germany will stir sediment on the sea bottom and harm fishing. However, most of the harmful effects would be local and of short duration, newspaper Helsingin Sanomat reports. The report reads that the pipeline would cause long-term problems for trawler fishing in the Gulf of Finland, and that wartime munitions sunk in the sea could detonate. The sea bottom in the Gulf of Finland would undergo considerable interference. Laying the pipeline and the dragging of the anchors of the installation vessel along the bottom would stir up bottom sentiment. Wartime munitions sunk in the sea could also detonate. Nord Stream will transport up to 55 billion cubic metres of gas each year, which is enough to supply more than 25 million households.
