The pipeline design is based on the following parameters –

1.             one 300 mm nominal diameter pipeline for the conveyance of liquid hydrocarbons;
2.          a flow rate of 15,899 sm3/d (0.100 MMbbl/d) of liquid hydrocarbons;
3.        a maximum internal design pressure of 14,893 kPag;
4.         a pipeline length of approximately 9.4 km.

1.         Materials of Construction

1.             Steel Pipe

The line pipe shall be in accordance with the requirements of the American Petroleum Institute Specification – API Spec 5LX, 35th Edition for Grade X52 seamless pipe and Esso Australia Limited Supplemental pipe specification accompanying the pipeline licence application.
