The map shows the international traffic separation scheme for shipping on the Dutch Continental Shelf (NCP) as part of the function of water in the provision of transport. The Dutch Continental Shelf (NCP) is one of the busiest seas in the world. As a trading nation, the Netherlands depends on the transport of goods. The main part of this takes place via waterways and across the North Sea. The North Sea is an important link in shipping routes and serves as a link between Europe and the other world markets. The sea and inland waterways make transport possible on a large scale and relatively inexpensive way. There is an extensive network of international shipping routes and fairways across the North Sea, the traffic separation system, which is intended to keep shipping traffic on the right track. Originally intended to increase safety, the traffic separation scheme also serves as an instrument for spatial planning at sea and for the protection of the marine environment. The traffic separation system ensures that the ships can keep an optimal, safe distance from each other, from oil and gas platforms and from other objects such as wind farms. Opposite traffic flows towards the ports are separated and large tankers sail via the 'deep water route', further offshore. Recreational vessels are not allowed to use this route. Rijkswaterstaat supervises and supervises traffic at sea. At sea, conflicts with other uses can arise, such as the establishment of protected status areas, reservation of areas for offshore energy generation, and oil and gas exploration and production.
