The realignment of the Whitby 100 Line was carried out due to a new subdivision being developed in Porirua.
Our scope included the Welding, Lower and Lay and Hydro-testing of the completed line.
Due to the Ohau River erosion and alignment change, a new river crossing for this main gas feed to Wellington was necessary. The pipe was welded as one string then using HDD was fed under the Ohau River. After hydro-testing, the tie-ins at either side to the existing pipeline were completed.No albums to view yet.
