How can Nord Stream be sure that the route selected for the pipelines will not be affected by munitions dumps, mines or other dangerous objects in the Baltic Sea?
The survey campaigns were conducted using state-of-the-art high resolution equipment, ensuring that potentially dangerous objects even as small as a can of coke, were identified. Nord Stream employed, for example, a gradiometer array that is the most advanced available on the commercial market. It has a tracking swathe of seven metres. The gradiometer array was specifically developed for the Nord Stream project to meet the particular challenges of one of the most extensive seabed surveys.
