Variation of Pipeline Licence VIC/PL25 (Whiting/Snapper) (7GGBDT)

Overview

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 was enacted to address the need for a comprehensive legal framework governing the exploration, production, and storage of petroleum and greenhouse gas in Australian offshore areas. This Act was designed to provide for the sustainable development of Australia's offshore petroleum resources while also ensuring the protection of the marine environment. The policy objective underpinning this legislation is to balance the economic benefits of offshore petroleum activities with the imperative to protect the marine ecosystem and ensure public safety. The Act was enacted by the Parliament of Australia and establishes a regulatory regime that includes the granting of titles, the issuance of licences, and the imposition of conditions to mitigate environmental impacts. The legislation aims to provide a robust and transparent framework for the offshore petroleum industry, promoting responsible resource management and minimising potential risks to the environment and human health.

Scope and Application

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 (Cth) applies to the licensing and regulation of offshore petroleum and greenhouse gas storage activities, including the construction, operation, and decommissioning of pipelines associated with such activities. In this context, the Act applies to the registered titleholders of the pipeline, specifically Esso Australia Resources Pty Ltd and Woodside Energy (Bass Strait) Pty Ltd. The Act has a national reach, governing activities across all Australian offshore areas, and it provides the framework for the variation of pipeline licences such as VIC/PL25. The variation detailed in the gazette alters the pipeline's route and specifications, ensuring compliance with the legislative and operational requirements set forth in the Act. While the Act itself outlines the broad scope of its application, specific operational and technical details are further regulated through subordinate instruments and industry standards, such as those referenced in the API Spec 5L and the Esso Australia Limited specifications. This legislation does not explicitly state exclusions or exemptions but operates under the principle that all activities must comply with the overarching regulatory requirements designed to ensure safety, environmental protection, and efficient management of offshore resources.

Key Provisions

The main operative sections of this legislation involve the variation of Pipeline Licence VIC/PL25 (section 226) for the pipeline connecting the Whiting and Snapper platforms. This variation specifies the pipeline route (section 264) and the pipeline design and materials (section 708). The variation takes effect on the publication date of the notice in the Australian Government Gazette. The new route of the pipeline is precisely defined, starting at the cut spool location at the Whiting platform and ending at the first flange upstream of the First Valve On (FVO) on the Snapper platform. The pipeline will be a 200 mm nominal diameter steel pipe designed to carry gaseous and liquid hydrocarbons at a flow rate of 3500 sm³/d of liquid hydrocarbons, with a maximum internal design pressure of 21,000 kPag and a design temperature of 60°C. The obligations imposed by this Act on the parties involved, Esso Australia Resources Pty Ltd and Woodside Energy (Bass Strait) Pty Ltd, include adhering to the detailed specifications for the pipeline's design, materials, and protective coating. The pipeline must comply with the American Petroleum Institute Specification – API Spec 5L, 36th Edition for Grade B seamless pipe and the Esso Australia Limited supplemental pipe specification. The steel pipe must have dimensions of 219.1 mm outside diameter with 25.4 mm wall thickness, and the line pipe must be protected by a coating of Taubmans HD 3005 Fusion Bonded Epoxy, 400-500 microns thick, as per the Esso Australia Limited Protective Coatings Specifications. These specifications ensure that the pipeline is built and maintained to the required safety and operational standards. Any breaches of the provisions outlined in this legislation may result in various consequences. While specific offences, penalties, or civil/criminal consequences are not detailed in the text, it is implied that non-compliance with the design, materials, and protective coating specifications could lead to enforcement actions by the relevant authorities. Such actions may include fines, remedial works, or other regulatory measures to ensure compliance with the Act. The severity of penalties would depend on the nature and extent of the breach, as well as any resulting harm or risk to public safety and the environment.
