Overview

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 was enacted by the Parliament of Australia to establish a regulatory framework for the exploration, production, and storage of offshore petroleum and greenhouse gas. This legislation aimed to address the need for effective management and regulation of offshore petroleum activities to ensure environmental protection, safety, and sustainable development. The Act provides for the granting of titles to explore for and produce offshore petroleum and the regulation of activities associated with these titles. Additionally, it covers the storage of greenhouse gases and establishes mechanisms for the protection of the marine environment. The policy objective of the Act is to balance the economic benefits of offshore petroleum activities with the need for environmental protection and sustainable resource management.

Scope and Application

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 applies to this application for the variation of a pipeline licence, specifically the Pipeline Licence WA-19-PL, in the offshore area of Western Australia. The application pertains to entities Chevron Australia Pty Ltd, Mobil Australia Resources Company Pty Limited, Shell Australia Pty Ltd, Osaka Gas Gorgon Pty Ltd, MidOcean Gorgon Pty Ltd, and JERA Gorgon Pty Ltd. The Act governs the regulation of offshore petroleum activities and greenhouse gas storage, ensuring that such activities are conducted in a manner that is safe, environmentally responsible, and efficient. The Act's jurisdiction covers federal waters, which are defined as waters beyond state boundaries and are subject to Commonwealth legislative control. The application seeks to modify the authorised route of the pipeline and update design and construction parameters in line with industry standards. The application is open to public submissions within 30 days from the date of this notice, as stipulated by subsection 226(3) of the Act. The notice takes effect from the date of its appearance in the Australian Government Gazette. The Act allows for further specification and restrictions through subordinate instruments, but no such extensions or restrictions are noted in this particular application.

Key Provisions

Sections 226 and 708 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 detail the process for varying a pipeline licence. An application has been received from several entities, including Chevron Australia Pty Ltd, Mobil Australia Resources Company Pty Limited, Shell Australia Pty Ltd, Osaka Gas Gorgon Pty Ltd, MidOcean Gorgon Pty Ltd, and JERA Gorgon Pty Ltd, for variations to Pipeline Licence WA-19-PL. The primary changes proposed involve altering the authorised route and updating the design and construction parameters of the pipeline. The application specifies new pipeline coordinates and references updated maps that replace the existing pipeline route map. The Act imposes various obligations on the applicants. These include ensuring that the pipeline is designed and constructed in accordance with specified industry standards, such as DNV-ST-Fl0l for submarine pipeline systems and ASME B31.8 for piping within manifold and PTS structures. Additionally, the applicants must adhere to detailed design parameters, including material specifications, nominal diameters, wall thicknesses, and design pressures. The pipeline must also be protected from external corrosion through the use of anti-corrosion coatings and cathodic protection systems. The design life of the pipeline is set at 50 years, and the maximum daily capacity rate for conveying wet natural gas is specified. Failure to comply with the provisions of the Act can result in significant consequences. While the specific offences, penalties, or consequences for non-compliance are not detailed in the notice, the Act generally provides for both civil and criminal penalties for breaches. Civil penalties may include fines, while criminal penalties can include imprisonment, reflecting the serious nature of non-compliance with offshore petroleum and greenhouse gas storage regulations. The maximum penalties would be determined based on the specific breach and the relevant sections of the Act.
