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. |
Overview
The Offshore Petroleum and Greenhouse Gas Storage Act 2006 was enacted by the Commonwealth Parliament to regulate the exploration, production, and storage of petroleum and greenhouse gas in Australian waters. The Act was introduced to address the need for comprehensive legal and regulatory frameworks governing offshore petroleum activities to ensure they are conducted in a safe, environmentally responsible, and sustainable manner. The policy objective of the Act is to facilitate the development of Australia's offshore petroleum resources while protecting the marine environment and ensuring that the rights of stakeholders are safeguarded. The Act provides a comprehensive legal framework for the regulation of offshore petroleum activities, including the issuance of licences, the imposition of conditions, and the enforcement of compliance. It also establishes mechanisms for the resolution of disputes and the management of environmental risks associated with offshore petroleum activities.
Scope and Application
The Offshore Petroleum and Greenhouse Gas Storage Act 2006 (the Act) applies to the granting of pipeline licences for the purpose of transporting petroleum offshore in Commonwealth waters, including state waters. The Act is administered by the National Offshore Petroleum Titles Administrator, who has the authority to grant pipeline licences under section 708. The Act applies to the specific pipeline licence VIC/PL43 for petroleum, which has been granted to Cooper Energy (Sole) Pty. Ltd. The licence pertains to the Sole system of pipes, with a defined route from the Eastern side of the Sole Pipeline End Manifold to the boundary of Commonwealth offshore waters at a 3 nm limit. The geographical scope of the Act extends to offshore waters within the Commonwealth of Australia, including state waters, and the specific application here is within the jurisdiction of Victoria. The Act does not specify exclusions or exemptions for this particular licence, but it is subject to compliance with the detailed specifications provided, including adherence to the offshore standard DNV-OS-F101 and Australian Standard AS2885.4. The Act's application can be extended or restricted through subordinate instruments, which may include regulations or codes of practice that provide additional detail on the standards and requirements for pipeline operations.
Key Provisions
The main operative sections of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 relevant to the grant of Pipeline Licence VIC/PL43 pertain to the authorisation of pipeline construction and operation within Australian offshore waters. Specifically, section 708 (referenced in the document) pertains to the grant of pipeline licences, providing Cooper Energy (Sole) Pty. Ltd. with the legal right to construct and operate the pipeline in accordance with the specified terms and conditions (section 708). The grant is contingent on compliance with the Offshore Standard DNV-OS-F101 – Submarine Pipeline Systems, as well as other detailed specifications outlined in the licence and supporting documents.
Cooper Energy (Sole) Pty. Ltd. is required to adhere to a comprehensive set of obligations and requirements. These include ensuring the design and construction of the pipeline meet the standards set by DNV-OS-F101 and AS2885.4, which covers submarine pipelines. The company must also provide detailed plans and descriptions of the pipeline’s route, including the tie-in spools to Sole-3 and Sole-4 XTs, as specified in the licence. Additionally, Cooper Energy must implement cathodic protection measures to manage external corrosion, using a low profile sacrificial cathodic anode system as described. Compliance with these obligations is further enforced through regular inspections and measurements by the regulatory authorities.
Failure to comply with the conditions of the Pipeline Licence VIC/PL43 may result in various civil and criminal consequences. Offences under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 can include the unauthorised operation of the pipeline, non-compliance with safety standards, and failure to implement required protective measures. Penalties for breaches can include fines and potential imprisonment for serious offences. For instance, the maximum penalty for contravening the Act could be substantial, with specific amounts often determined by the severity and impact of the breach. Furthermore, ongoing non-compliance or significant safety breaches could lead to the suspension or revocation of the pipeline licence, thereby halting operations and potentially leading to further legal action.
