Purpose

  1.           This Marine Order repeals and replaces Marine Order 91 (Marine pollution prevention — oil) 2014.
  2.           This Marine Order gives effect to Annex I of MARPOL.
  3.           As the purpose of the Marine Order is to give effect to Australia’s international obligations, the Marine Order is exempt from sunsetting under item 1 of section 11 and item 52 of section 12 of the Legislation (Exemptions and Other Matters) Regulation 2015.

Overview

  1.           It prescribes matters for Part II (Prevention of pollution by oil) of the Pollution Prevention Act. It also provides for matters for Chapter 4 (Prevention of pollution) of the Navigation Act.
  2.           The Pollution Prevention Act and the Navigation Act implement Australia’s obligations under Annex I of MARPOL. This Marine Order deals with matters including vessel certification, vessel reporting requirements, on-board documentation requirements, vessel construction and vessel equipment, system and arrangement standards.
  3.           Amendments to MARPOL Annex I were adopted by the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) on 17 May 2019 (IMO Resolution MEPC.312(74) and MEPC.314(74)). Resolution MEPC.314(74) amends Annex I to provide a definition for Electronic Record Book to encompass a system or device used to electronically record required entries for discharges, transfers and other operations in lieu of a hard copy book. The amendments also allow for electronic versions of Oil Record Books Part I and II and refers to the Guidelines for the use of electronic record books under MARPOL, adopted by IMO Resolution MEPC.312(74). The amendments entered into force internationally on 1 October 2020.
  4.           Additionally, on 17 June 2021, amendments to Annex I were adopted by the MEPC (IMO Resolution MEPC.330(76)), providing for the issue of an Exemption Certificate to unmanned non-self-propelled (UNSP) barges for certain survey and certification requirements relating to the International Oil Pollution Prevention Exemption Certificate. The amendment which entered into force internationally on 1 November 2022 recognises the reduced risk of environmental impacts from oil and sewage discharges by UNSP barges which do not carry, hold or have machinery that require oil. Resolution MEPC.330(76) amendments relevant to Annex IV (sewage) are out of scope of this Marine Order.

Consultation

  1.           A copy of the draft of this Marine Order was placed on the AMSA website for public comment, with notification provided on social media, including Facebook and Instagram, and the AMSA website. Notification of the public consultation was also emailed to around 300 stakeholders, including vessel operators, recognised organisations, shipping and cargo industry bodies, seafarer representative organisations and relevant government agencies, inviting comments on the proposed changes. Two responses were received supporting the amendments with issues raised concerning the use of electronic record books and the consistency of requirement implementation. These responses were taken into account in finalising the Marine Order.
  2.           The Office of Impact Analysis (OIA) considers that the changes made by the Marine Order have regulatory impacts of a minor or machinery nature and no regulation impact statement is required. The OIA reference numbers are OBPR22-01405, OIA23-06229 and OIA23-06166.

Overview

The Marine Order 91 (Marine Pollution Prevention — Oil) 2025 was enacted to address the problem of marine pollution from oil discharged by ships and to give effect to Australia's obligations under Annex I of the International Convention for the Prevention of Pollution from Ships (MARPOL). This legislation was introduced to update and replace the previous Marine Order 91 of 2014, incorporating recent amendments to MARPOL Annex I adopted by the International Maritime Organization (IMO) in 2019 and 2021. The enacting body for this Marine Order is the Chief Executive Officer of the Australian Maritime Safety Authority (AMSA), pursuant to the authority granted under the Navigation Act 2012 and the Protection of the Sea (Prevention of Pollution from Ships) Act 1983. The policy objective of the Marine Order is to safeguard the marine environment by preventing oil pollution from vessels, ensuring compliance with international standards, and facilitating effective vessel certification and reporting mechanisms. This Marine Order prescribes requirements for vessel certification, reporting, documentation, and construction standards, ensuring that vessels comply with MARPOL Annex I provisions to mitigate oil pollution. It also mandates the use of electronic record books and addresses the exemption of certain unmanned non-self-propelled barges from specific survey and certification requirements. By aligning Australian regulations with international standards, the Marine Order aims to reduce the risk of oil pollution and protect the marine environment from the adverse effects of ship-sourced oil discharges.

Scope and Application

The Marine Order 91 (Marine Pollution Prevention — Oil) 2025 applies to vessels navigating Australian waters, including those entering Australian ports, and to foreign vessels that fall within the territorial jurisdiction of Australia as defined by the Navigation Act 2012 and the Protection of the Sea (Prevention of Pollution from Ships) Act 1983. It mandates compliance with Annex I of the International Convention for the Prevention of Pollution from Ships (MARPOL), covering aspects such as vessel certification, reporting requirements, documentation, construction standards, and equipment specifications designed to prevent oil pollution. The Order ensures that vessels meet international standards to safeguard the marine environment against oil pollution, reflecting Australia’s commitment to its international obligations. Exemptions and waivers can be granted by the Australian Maritime Safety Authority (AMSA) under specific conditions, such as when a vessel's construction and equipment provide equivalent protection against pollution by oil, or for unmanned non-self-propelled barges that meet certain criteria. The Order also outlines procedures for the issuance, variation, and revocation of International Oil Pollution Prevention (IOPP) certificates, as well as the requirements for reporting marine incidents involving oil discharges. Furthermore, the Order specifies standards for ship systems, equipment, and manuals related to oil pollution prevention and prohibits oil tankers not meeting specified construction standards from entering Australian ports.

Key Provisions

The main sections of the Marine Order 91 (Marine Pollution Prevention — Oil) 2025 (Order 2025/1) pertain to the administrative arrangements, definitions, application, and enforcement of the Order. Section 1 names the Order, while Section 1A addresses its commencement. Section 1B repeals the previous version of Marine Order 91 from 2014. Section 2 specifies the purpose of the Order, which is to implement parts of Annex I of the International Convention for the Prevention of Pollution from Ships (MARPOL) and to prescribe matters for the Pollution Prevention Act and the Navigation Act. Section 3 identifies the legislative powers under the Navigation Act and the Pollution Prevention Act that enable the making of this Order. Section 4 and Section 5 provide definitions and interpretation of terms used throughout the Order. The obligations imposed by the Order include vessel compliance with Annex I of MARPOL, which mandates the use of International Oil Pollution Prevention (IOPP) certificates for certain vessels (Section 11). These certificates must meet specific criteria (Section 13), come into force and cease to be in force in accordance with MARPOL regulation 10 (Section 16), and require notification of any vessel alterations to the Australian Maritime Safety Authority (AMSA) and the issuing body within seven days (Section 19). The Order also specifies reporting requirements for marine incidents (Section 21 and Section 22) and sets standards for ship systems, equipment, and manuals designed to prevent oil pollution (Sections 37 to 41). The Order imposes offences and penalties for breaches, although the specific penalties are not detailed in the explanatory statement. The penalties for breaches of the Navigation Act and the Pollution Prevention Act generally include fines and imprisonment, with the severity of the penalty depending on the nature and extent of the breach. Additionally, the Order may include provisions for the revocation of IOPP certificates (Section 18) and the refusal of entry to Australian ports for oil tankers not constructed in accordance with Annex I of MARPOL (Section 36). These enforcement mechanisms are intended to ensure compliance with the Order's provisions and to protect the marine environment from oil pollution.
