Safety resources

NOPSEMA has developed a series of advice documents to inform and assist stakeholders to interpret and meet the requirements of the Offshore Petroleum and Greenhouse Gas Storage (Safety) Regulations 2009 and relevant state legislation where a state or the Northern Territory has conferred regulatory powers and functions to NOPSEMA.

NOPSEMA's advice documents should not be relied on as advice on the law, nor treated as a substitute for legal advice in any relevant situation. NOPSEMA's assessment of a regulatory permissioning document, monitoring and enforcement activities, are undertaken in accordance with the regulations.

NOPSEMA’s advice documents are subject to periodic review and update. Comments and suggestions on the content of any advice documents are welcomed can be directed to
