This project was unusually complex due to the large number of
buried structures on the site. The poor soil on the Grain peninsula means that
nearly all structures have piled foundations, which the drill must steer
underneath or around. The most significant of these is a cryogenically cooled
LNG pipeline, which is very sensitive to ground settlement.
The location of buried structures and the arrangement of the
wayleave made the routing of the drill difficult, and it was necessary to
introduce a horizontal curve into the drill and also to string the pipe out in
two sections prior to pullback.
Though not a straightforward drill, the surface structures,
vast number of buried services, contaminated ground and ecological significance
of the site meant that Horizontal Directional Drilling was still a preferable
technique to traditional pipe laying methods. Bennett Associates’ ability to
react quickly to changing requirements and new information were invaluable to
the success of the project.
