About the project
Esso has a number of pipelines which transport crude oil, condensate and LPG from our Longford gas processing and crude oil stabilisation plants in Gippsland to our Long Island Point plant, situated near Hastings.
Esso is currently replacing the 187 kilometre pipeline that transports crude oil and condensate between these facilities. The replacement pipeline is being constructed adjacent to existing pipelines and within easements held by Esso, which are set aside for its crude oil, condensate and LPG pipelines.
Esso awarded the contract to construct the replacement pipeline to Nacap Australia (a Quanta Services company).
About the pipeline
The original pipeline was laid in 1969 as part of the massive infrastructure investment to develop, produce and process the crude oil and gas discovered in Bass Strait since 1965. The replacement pipeline, which is 350mm diameter, will replace the existing pipeline which is now approaching the end of its operational life. This replacement pipeline will not only allow the continued delivery of crude and condensate, but will also be required so that natural gas from Esso’s offshore Gippsland operations – which is produced along with these liquids – continues to flow to Australian households and businesses.
Work on the $400 million pipeline project commenced near Rosedale, 30 kilometres east of the Longford gas processing and crude oil stabilisation plants in late January 2016. The commencement of construction was recognised at a ceremony on 17 February 2016 attended by Richard Owen, Chairman of ExxonMobil Australia the Hon. Lily D’Ambrosio MP, Minister for Energy and Resources and Cr. Darren McCubbin, Mayor of Wellington Shire Council.
The project is progressing well with 130 kilometres of the 187 kilometre pipeline route now installed. In many areas which were excavated to make way for the new pipeline, topsoil has been replaced and NACAP is working to remediate the land in line with landowner expectations. To ensure the ongoing success the rehabilitation process, Esso continues to monitor progress and is staying in regular contact with landowners.
The pipeline is being laid mostly using standard excavation and trenching techniques; however in some locations, trenchless construction using horizontal directional drilling has been employed. This technique involves drilling a hole below the surface and then pulling a welded length of pipe through the hole without disturbing or impacting the surface. These operations are highly engineered and are used in cases where trenching is not feasible such as crossing watercourses, railways, major public roads, or in environmentally and culturally sensitive areas. The project has now completed 52 horizontal directional drilling operations of varying sizes at various locations along the pipeline route.
As we move into winter and the wetter months of the year, construction has ceased as the ground is not suitable to undertake further work. Construction crews will re-commence work later this year.
Construction of the pipeline is occurring predominantly on private land within easements held by Esso, which are set aside for its crude oil, condensate and LPG pipelines.
Since planning of this project began in 2013, Esso has been liaising with over 300 individual landowners to ensure we mitigate potential impacts on landowners and occupiers and the various activities they undertake on their land.
Detailed property management plans and remediation programs have been developed with each individual landowner to ensure their land is returned to them in a suitable condition.
Contributing to the local community
In our many years of operations across Gippsland, Esso has a strong track record of supporting local contractors and suppliers. Our construction contractor, Nacap, also has had a strong presence in the various communities this project passes through. Since the beginning of construction works, Nacap have engaged a number of local suppliers in the Gippsland region and along the pipeline route, for a variety of products and services including concrete, structural steel, safety equipment, machinery, welding, tools, building supplies, training services and accommodation. Nacap has also based its project office in Morwell and its employees have become regulars at many of the local cafes and other businesses. Overall Australian labour, materials and equipment are estimated to make up around 90% of the project spend.
