Pre-FEED and FEED
East Plant to West Plant Pipelines
One study involved linking the services between the East and West plants i.e. Ammonia, Hydrogen, Nitrogen, Non-Potable Water, and 33kV and Controls Infrastructure.
This study looked at various options for routing the pipelines both above and below ground. Due to the nature of the area around the docks, the pipelines needed to cross a road and road embankment, railway line, the newly constructed Border Control Post, as well as multiple landowner sites, before finally crossing the road into the west plant.
As a result of the congestion in the area, an underground route via an ~800m trenchless horizontal directional drilling (HDD) was selected. As part of the FEED study, OLG engaged a specialist trenchless crossings contractor who provided support with the design and construction requirements of the trenchless crossings.
