McConnell Dowell Ltd – Mobil Exxon Fuel Line
The Mobil Lyttleton to Woolston Pipeline (LWPL) was an existing DN100 pipeline which delivered 95 and 91 unleaded petrol (ULP) and automotive gas oil – diesel (AGO) from the Mobil Lyttleton terminal to the Mobil Woolston terminal. Future plans for the pipeline include transportation of Jet A1 aviation fuel.
A section of this pipeline ran through the Heathcote Valley Primary School property, and there was a larger buried DN150 pipeline in Kiwi Rail land, adjacent to the school. The scope of works was therefore to replace this section of the pipeline to divert the pipeline outside of the school boundary and down the Kiwi Rail corridor.
The replacement section of pipeline extended up the Bridle Path Road to a tie-in location above the Lyttelton Tunnel entrance of the Tunnel Road motorway at chainage 2950. The tie-in location on the downstream end of the replacement section was located beside Station Road after the location of the Heathcote Valley School at chainage 4160.
The total length of the replacement section was approximately 1210m, with the new pipeline section following a similar route to the old pipeline section in the Bridal Path Road.
