SPECIFICATIONS
2. The Schedule under Specifications, Basis of Design table is varied by updating the items in bold and italics:
Basis of Design
The pipeline design is based on the following parameters:
Item | Item Description | 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. |
3 | Length | 262 km (approximate) |
4 | Design life | 25 years (approximate) |
5 | Pipeline Material | Steel |
6 | Pipeline Steel Grade | Grade 450 |
7 | Pipeline Specification | DNVGL SAWL 450 F D S (U in specified regions) |
8 | Minimum yield strength of pipe steel | 450 MPa |
9 | Maximum Allowable Incidental Pressure | 20.8 MPag |
10 | Design Capacity | 730 MMscf/d |
11 | Maximum Design Temperature | 60⁰C |
12 | Minimum Design Temperature | 0⁰C |
13 | Characteristics of substance proposed to be conveyed | Dehydrated natural gas |
14 | General plans and descriptions of pump stations, tank stations or valve stations and their equipment | N/A |
15 | 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. |
3. The NT/PL5 Pipeline Route Map at Annexure A is deleted and replaced with the map at Attachment 1.
