SPECIFICATIONS

 

Design and Construction

 

The offshore pipeline must be designed and constructed in accordance with 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:

Details

1

Outside diameter of pipe

26 inches nominal

2

Wall thickness of pipe

23.6 mm and 19.7 mm

 

(23.6 mm wall thickness pipe is utilised adjacent to the facility to meet Location Class requirements. 23.6 mm is also utilised in areas subject to spanning to optimise the span design.)

General plans and description of pigging facilities

The pipeline is designed to enable operational inspection pigging to be performed if required based on a risk-based inspection regime.

 

The riser base manifold is equipped with a full bore connection point, isolated by two 26-inch valves, to facilitate the installation and removal of a subsea pig launcher by diverless means.

 

The riser base manifold, spools, pipeline and tie-in to the existing Bayu-Undan pipeline are designed to facilitate through pigging to the onshore pig receipt facilities at DLNG.

16

Cathodic protection

Aluminium-Zinc-Indium Anodes DNVGL-RP-F103

Typically spaced at 1 anode every 8 pipe joints.

17

Hydrate Management

Hydrate management in the gas export pipeline is not required as the pipeline is classified as a dry gas pipeline.
