DELEGATE OF THE TITLES ADMINISTRATOR

ON BEHALF OF THE COMMONWEALTH-VICTORIA

OFFSHORE PETROLEUM JOINT AUTHORITY

 

 

 

 

 

 

 

 

 

 

PROPOSED ROUTE OF THE PIPELINE

 

The proposed pipeline route is described in the table hereunder, commencing at the Sole-3 and
Sole-4 wellheads and ending at the 3 nautical mile (nm) State coastal waters boundary. Coordinates are based on Geodetic Datum of Australia (GDA94). See map at Attachment 1.

SPECIFICATIONS

 

Design and Construction

 

The offshore pipeline must be designed and constructed in accordance with DNV Offshore Standard DNV-OS-F101 – Submarine Pipeline Systems (Offshore Pipeline), which is incorporated in its entirety in Australian Standard AS2885.4 – Pipelines, Gas and Liquid Petroleum (Part 4: Submarine Pipelines). Specifically, the design and construction phase of the pipeline must comply with DNV-OS-F101.

 

Basis of Design

 

The pipeline design is based on the following parameters:

15

General plans and descriptions of pump stations, tank stations or valve stations and their equipment

A PLEM will be installed adjacent to the Sole-3 wellhead and welded to the end of the 12” pipeline. The PLEM will facilitate the connection of up to two subsea wells to the 12” pipeline via 6” alloy tie-in spools. The offshore section of the Sole pipeline does not include any further in-line facilities.

16

General plans and description of pigging facilities

Temporary pig launchers and receivers will be installed at the PLEM and onshore plant.

17

Cathodic Protection

External corrosion management shall be via sacrificial anode systems, designed to be maintenance free and monitored via ROV inspection and measurement where required as part of regulatory surveys.
