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) as amended from time to time, which is incorporated in its entirety in Australian Standard AS2885.4 – Pipelines, Gas and Liquid Petroleum (Part 4: Submarine Pipelines) (as amended from time to time). 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:
Item | Item Description | Details |
1 | Outside diameter of pipe | 12” rigid flowline: 305 mm |
2 | Wall thickness of pipe | 12” rigid flowline: 17 – 19.4 mm |
3 | Length | 57.96 km (approximate) |
4 | Design life | 15 years (approximate) |
5 | Pipeline Material | Carbon Steel |
6 | Pipeline Steel Grade | DNV-OS-F101 Grade 450 |
7 | Pipeline Specification | DNV-OS-F101 Seamless |
8 | Minimum yield strength of pipe steel | 450 MPa |
9 | Maximum Allowable Operating Pressure | 12” rigid flowline: 13.2 MPa 6” tie-in spools: 13.2 MPa |
10 | Design Capacity | Gas flow: 67.5 MMscf/d |
11 | Maximum Operating Temperature | 12” rigid flowline: 40◦C 6” tie-in spools: 40◦C |
12 | Maximum Design Temperature | 12” rigid flowline: 50◦C 6” tie-in spools: 50◦C |
13 | Minimum Design Temperature | 12” rigid flowline: 0◦C 6” tie in spools: -10◦C |
14 | Characteristics of substance proposed to be conveyed | Gas and condensate |
15 | General plans and descriptions of pump stations, tank stations or valve stations and their equipment | N/A |
16 | General plans and description of pigging facilities | Temporary subsea pig launchers and receivers will be installed at the PLEM. |
17 | Cathodic Protection | External corrosion management shall be via a low profile sacrificial cathodic anode system. Bracelet anodes, positioned approximately every 24 joints, will be connected via doubler plates welded to the pipeline. The system is, designed to be maintenance free and monitored via ROV inspection and measurement where required as part of regulatory surveys. Anode design and supply will be in accordance with DNV-RP-F103. |
