The gas produced by the Northern fields in the North Sea comes on shore at St. Fergus, Scotland. To link the terminal in St. Fergus to the national grid at Bishop Auckland, Durham, British Gas Corporation planned a 42 inch onshore pipeline along the coast. Two river estuaries had to be crossed: The river Tay and the river Forth. The latter is the widest; at the crossing location the rivermouth is 18 kilometers wide. The waterdepth reaches 60 meters. With the coastline only 10 kilometers to the east this area is exposed to the North Sea tide currents and waves. Hard material in the pipeline route at greater waterdepth, was facing the pipelaying contractor. Several possibilities have been looked at and after careful consideration a solution with a trailing suction hopper dredger was chosen as the most reliable and feasible for this kind of operation.
