Main Street 1549 Revives Major South African Offshore Gas Development Push

Main Street 1549 has opened a fresh regulatory chapter for the Brulpadda and Luiperd gas-condensate discoveries, submitting a new environmental authorization application for their development in Block 11B/12B offshore South Africa.

The filing advances efforts to commercialize one of the country’s most significant offshore gas resources.

Africa Energy submitted the application through its investment in Main Street 1549.

The move revives efforts to develop the discoveries after earlier plans stalled and a previous environmental authorization application was withdrawn.

That earlier application had been submitted in February 2025. Main Street has now filed its replacement with the Petroleum Agency of South Africa, known as PASA, in support of the company’s continuing Production Right application.

As part of the new environmental authorization process, the company has issued a draft scoping report for public review and comment.

This consultation represents the current stage of the application and must be completed before the company submits its final scoping report.

Brulpadda was discovered in 2019, followed by Luiperd in 2020. The two gas-condensate finds rank among the largest offshore gas discoveries made off South Africa and have long been viewed as a potential catalyst for the country’s domestic gas industry.

Main Street is examining two optional full field development scenarios for the deepwater discoveries. Both concepts are intended to provide possible routes for bringing the block’s gas resources into regional or export markets.

One option would transport produced gas to shore through a pipeline. That pathway would establish a direct link between offshore production from Block 11B/12B and facilities on land.

The second concept would process the gas offshore into LNG. Under that scenario, the LNG could be supplied to export and regional markets rather than moving the produced gas ashore through a pipeline.

Main Street has not selected a final development concept. Its eventual choice between the pipeline and offshore LNG pathways will depend on factors that include future regional gas demand and prevailing market conditions.

The discoveries are located in a block that was formerly operated by TotalEnergies. Main Street currently holds a 10% interest in Block 11B/12B while the regulatory process and proposed ownership restructuring remain under way.

After the public consultation process is completed, Main Street plans to submit a final scoping report to PASA for approval. Approval of that report would allow the project to move into the next stage of environmental review.

If PASA approves the final scoping report, Main Street will proceed to the impact assessment phase.

That phase will begin with preparation of a draft environmental and social impact assessment report, identified as the ESIA report.

Approval of the ESIA report is required before the production right can be granted. The environmental authorization process therefore runs alongside Main Street’s broader effort to secure the regulatory approvals needed to advance development of Brulpadda and Luiperd.

The company’s potential interest in the block could also change substantially. Subject to approvals from South African authorities concerning the withdrawal of the other Block 11B/12B partners, as well as completion of Main Street’s restructuring, the company would hold a 75% interest.

Those conditions mean the proposed increase from Main Street’s current 10% interest has not yet been completed.

The ownership outcome remains tied to regulatory approval for the other partners’ withdrawal and completion of the company’s restructuring.

For now, the new environmental authorization filing returns attention to the development choices facing the project.

Main Street is advancing the regulatory process while assessing whether a pipeline to shore or offshore LNG processing offers the preferred route for the discoveries.
