Gas Pipeline Construction

By Robert Driessen

Duke Energy International constructed the Tasmania Natural Gas Pipeline from Victoria on the Australian mainland to Bell Bay on the island state of Tasmania.  They also constructed two spurs, one to the Tasmanian capital of Hobart and the other to Port Latta, an iron ore shipping terminal on the north west coast.

Duke’s Route selection crews operating in the field required reliable information to help them selected the optimum route for the proposed pipeline.  All field operatives were experienced in pipeline constructions but had little exposure to computers.  Duke Energy International required an easy to use application that would provide the route selection crews with the best available data.

The pipeline affected more than 1000 land holdings and so Duke employed a team of Land Liaison Officers to engage with individual landowners and manage their concerns.  The Land Liaison Officers needed to report on the outcome of each landowner contact and record contact details including their concerns, access restrictions and other issues.  The Officers operated remotely without permanent links to the Duke network.  However details of landowner contacts had to be forwarded to a central office where it would be collated in a central repository.  This information would then pass onto construction and maintenance crews so they were aware of the issues as they moved onto each land holding.

The Role of RIA Mobile GIS in the project

RIA Mobile GIS designed and developed the Tas Pipeline Mapper. This application was based on ESRI GIS technology and incorporated a wealth of infrastructure, topographic, environmental and cultural data, gathered from a variety of sources.  The standard ESRI GIS interface was altered so that it was easy to use and less inhibiting for non-computer literate operators.  After two hours of training and additional practice the field operatives were able to quickly and confidently navigate to the required locations and obtain the necessary information required for route selection.

The Tas Pipeline Mapper became a key component of the pipeline construction process and grew to incorporate a number of other essential functions including contact management.  Design engineers and environmental scientists also used the product in the office environment.

RIA Mobile GIS also designed and developed a contact manager application.  Using the application Land Liaison Officers gained access to landowner details by clicking in the land parcel displayed on the map.  The application also allowed the officers to easily:
– Locate required land holdings either spatially or via textual key.
– Display landowner details on a dialog which also allow the recording and modification of contact details.
– Illustrate relationship between individual parcels in a land holding when required using appropriate graphics.
– Write reports on the contact in a memo field in Microsoft Access database.
– Integrate new and modified records with head office on a daily basis (when they were back on the network).
