Variation of Pipeline Licence WA-21-PL (Halyard Flowline)

Overview

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 was enacted to provide a framework for the regulation of offshore petroleum activities and greenhouse gas storage in Australia, aiming to balance the development of Australia's offshore petroleum resources with the protection of the marine environment and the interests of adjacent coastal states. This legislation was introduced to address the need for coordinated regulation of offshore petroleum activities in Australian waters, particularly in areas where state and federal jurisdictions overlap. The Act was enacted by the Parliament of Australia, and its policy objective is to ensure the sustainable development of Australia's offshore petroleum resources while minimising potential environmental impacts. The Act provides for the regulation of offshore petroleum activities, including the issuance and variation of licences and permits, and establishes the Commonwealth–Western Australia Offshore Petroleum Joint Authority as the body responsible for administering the Act in relation to the offshore area between Western Australia and the Northern Territory. The legislation in question is a Gazetted variation of a pipeline licence under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The National Offshore Petroleum Titles Administrator, on behalf of the Commonwealth–Western Australia Offshore Petroleum Joint Authority, has varied Pipeline Licence WA-21-PL, which pertains to the Halyard Flowline. The variation includes amendments to the authorised route, conditions of the licence, and technical specifications, such as the pipeline layout, coordinates, and design details. These changes aim to ensure that the pipeline operations comply with updated safety and environmental standards. The variation comes into effect on the date of its publication in the Commonwealth Government Gazette.

Scope and Application

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 applies to the regulation of offshore petroleum activities and greenhouse gas storage within the Commonwealth of Australia's jurisdiction, including the varying of pipeline licences as specified in the Act. The variation of Pipeline Licence WA-21-PL pertains to the Halyard Flowline, affecting the pipeline's authorised route, conditions, and design specifications as outlined in the licence instrument. The Act applies to entities involved in offshore petroleum activities, including those holding pipeline licences. The geographic reach of this Act extends to Commonwealth waters, and in this instance, specifically applies to Western Australia offshore petroleum activities. The variation takes effect from the date of publication of the notice in the Commonwealth Government Gazette, and it amends specific aspects of the licence while maintaining other conditions as previously set. The Act allows for the extension or restriction of its application through subordinate instruments, which are used here to modify the pipeline licence in detail.

Key Provisions

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 (the "Act") governs the variation of the Pipeline Licence WA-21-PL, which pertains to the Halyard Flowline. Section 226 of the Act provides the authority to vary the pipeline licence and specifies the changes to be made. The variation (section 3) modifies the "Authorised Route" by referring to an attached plan and table of coordinates, effectively replacing the previous specifications. The "Conditions of Licence" (section 4) have been entirely removed, simplifying the regulatory framework under which the pipeline operates. Annexure A (section 5) and Annexure B (section 6) have been updated to reflect new pipeline layout details and coordinate tables for the Greater East Spar system of pipes, respectively. The parties or entities governed by this variation must comply with the new specifications and requirements as outlined in the amended licence. The variations mandate adherence to the new pipeline layout, coordinates, and design details. These changes include the pipeline's physical dimensions, corrosion allowances, steel specifications, and operational parameters such as temperature and pressure limits. The variations also necessitate adjustments to the "Basis of Design" documentation, particularly in relation to the pipeline's length, design capacities, and pressure ranges. Failure to comply with the provisions of the Act and the varied licence may result in legal consequences. Although specific offences and penalties are not detailed in the variation itself, breaches of the Act can generally lead to civil or criminal penalties under the broader legislative framework. These may include fines, imprisonment, or other regulatory actions as prescribed by the Act. The exact penalties would depend on the nature and severity of the breach, as well as any additional guidelines or case law interpreting the Act's provisions.
