HDD - Installation gaspipeline under Westerschelde

By means of two horizontal directional drillings of 1,350 metres and 1,450 metres, Visser & Smit Hanab installed a 48" gas pipeline under the Western Scheldt (river, which flows directly into the North Sea) for the 'Nederlandse Gasunie'. In particular, the artificial island in the Western Scheldt where the 450 ton drill rig was set, is unique.

The gas pipeline is part of the nationwide expansion of the main 48" transport pipeline of Gasunie, the North-South Route. The Western Scheldt Crossing between Ossendrecht (NL) and Zelzate (B) is part of the Wijngaarden - Zelzate section.
