Esso pipeline replacement project

Abstract

Esso recently commissioned (October 2017) a new 350-mm 187-km-long pipeline for carrying crude and condensate from Esso’s Longford Plant (Longford) in Gippsland Victoria, along an existing easement to the Long Island Point facility (LIP) at Hastings, Victoria. This pipeline replaces an existing 700-mm pipeline that was approaching the end of its operational life.

Through continued delivery of crude and condensate, this pipeline also ensures that the natural gas which is produced along with these liquids continues to flow to Australian households and businesses. The project included pig launching and receiving facilities at Longford and LIP terminals, 10 main-line valve stations as well as fibre-optic cable for control, leak detection and communications purposes.

Early engagement of its contractor partners played a key role in the successful execution of the project. Today’s landscape along the pipeline route significantly differs from that when the original pipeline was installed. Individual needs of the landowners affected by the construction were carefully considered. Significant measures were taken to minimise any impact to the unique flora and fauna of the region. Sensitivities around cultural heritage locations were taken into account while finalising the construction methods.

Construction of the pipeline occurred in two summer phases (2015–2016 and 2016–2017) to make efficient use of dry weather and to minimise disturbance to landowners and the environment. The project was completed within budget and ahead of schedule.
