Offshore project proposals

NOPSEMA publishes offshore project proposals (OPP) that are open for public comment following its determination that the OPP is suitable for publication. The public then have an opportunity to review and provide comment on the OPP.

Providing the public with opportunities for participation and consultation is an integral part of environmental impact assessment and assists in ensuring responsible offshore petroleum environmental management.

All public comment submissions, including any objections or claims about the project or an activity in the project, are to be made directly to NOPSEMA. A copy of the comments received will be provided to the proponent for their consideration. The proponent must then submit to NOPSEMA a consultation report that includes a summary of the comments received, an assessment of the merits of each objection or claim about the project or any activity within the project, a statement of their response to each comment, and a description of any changes made to the OPP as a result of an objection or claim.

If the OPP meets the criteria set out in the Environment Regulations and the OPP is accepted, NOPSEMA will publish the final OPP in full on its website.

Proposal details Location Dates Status Details

Otway Development (OPP #7557)

Beach Energy

Project Description: Beach Energy (Operations) Australia Pty Ltd propose to develop the Project as a subsea development. The stages of the Project will include an initial drilling campaign operated by a semi-submersible MODU. Successful wells will be tied back to existing Otway Gas Production Pipeline (OGPP) and/or Thylacine A platform via installation of new subsea flowlines and facilities. Recovered gas will be transported through the OGPP to the onshore OGP located onshore near Port Campbell, Victoria.

The Project focuses on Beach’s exploration permits, VIC/P43, VIC/P73 and T/30P located in the offshore Otway Basin. The Project is located approximately 20km south of the Victorian mainland and 40 km west of Tasmania (King Island) at its closest points.
