SECOND SCHEDULE
SPECIFICATION
- Design
The pipeline design is based on the following parameters –
- one 300 mm nominal diameter pipeline for the conveyance of liquid hydrocarbons;
- a flow rate of 15,899 sm3/d (0.100 MMbbl/d) of liquid hydrocarbons;
- a maximum internal design pressure of 14,893 kPag;
- a pipeline length of approximately 9.4 km.
- Materials of Construction
- 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. There is a 4 km replacement section beginning at Mackerel and terminating at the flexible jumper. All replacement rigid line pipe has an external diameter of 323.9 mm and a wall thickness of 12.7 mm.
The original section of pipeline starts at the other side of the flexible jumper to Halibut. This section of pipeline has an outer diameter of 323.9 mm and a wall thickness of 9.53 mm.
The tie-in spool has an external diameter of 323.9 mm and a wall thickness of 12.7 mm thick. It also has a corrosion coating of 0.5 mm thick Fusion Bonded Epoxy and a 25 mm Concrete Weight Coating. The Concrete Weight Coating extended from the riser to tie-in spool flange connection to the tie-in spool to pipeline connection.
The flexible jumpers are fabricated from composite material manufactured by Coflexip and have a Nylon-11 pressure containing sheath. The flexible jumper is 65.8 mm long, has an internal diameter of 305 mm and a wall thickness of 55.2 mm.
- Protective Coating
Primary external corrosion protection for the pipeline is provided by a Coal Tar
Enamel coating and a high-density polyethylene coating called Yellow Jacket.
- Weight Coating
The specification for the steel mesh reinforced weight coating and the shop application of this material to the pipe shall be in accordance with the Esso Australia Limited Protective Coatings Specifications accompanying the original pipeline licence application.
