Crude oil is imported through a 36” pipeline that runs from a Single Buoy Mooring to a crude oil transfer terminal. The pipeline was originally installed and commissioned in 1971. The pipeline runs from the terminal through flat agricultural land, through an environmentally sensitive salt marsh, under the sands and seabed to a pipeline end manifold located below the Single Buoy Mooring.
Following pipeline integrity surveys, a requirement to replace a section of the pipeline was identified. PDi were engaged to undertake a feasibility study to investigate the replacement and decommissioning of the existing pipeline.
The purpose of the feasibility study was to review the environmental, planning and consents required to progress the project, identify the construction options and to develop schedule and cost estimates for each scenario to replace and decommission a section of the Crude Import Pipeline.
The three scenarios investigated during the feasibility study were as follows;
Commenced November 2011 (Duration 3 Months)
