Main Street 1549, the new operator of offshore block 11B/12B off South Africa, is examining several scenarios to commercialise the Brulpadda and Luiperd gas discoveries. Options under study include transporting gas to shore by pipeline and using floating production and liquefaction facilities. Concept selection must address a longstanding difficulty: the resources are substantial, but distance from infrastructure and uncertain markets complicate development.
The Brulpadda discovery, announced in 2019, and Luiperd, confirmed in 2020, lie in the Outeniqua Basin around 175 kilometres from the South African coast. The block covers deep waters, with depths reaching several hundred metres and more in some areas. Public estimates of recoverable volumes vary by scope and methodology; the debate concerns less the existence of gas than how to produce and sell it.
Two commercialisation routes
The first option is to build a subsea system and pipeline to shore. Gas could then supply power plants, industries or existing facilities, particularly around Mossel Bay. This would connect the field directly to consumers but require investment in pipelines, processing, onshore facilities and connections.
A pipeline also entails scheduling and permitting risks. Its route must be studied in relation to the seabed, fishing areas and coastal activities. Buyers able to sign long-term contracts and take sufficient volumes must also be identified. Without commercial visibility, infrastructure costs can make the project difficult to finance.
The second route envisages a floating liquefied natural gas (FLNG) unit that would process and convert gas into LNG offshore before loading it onto vessels. An FPSO — a floating production, storage and offloading unit — could be incorporated to separate and process produced hydrocarbons, particularly condensate. Precise configurations remain under study. These facilities can reduce dependence on some onshore infrastructure, but construction costs, deepwater operation and access to specialised vessels are major challenges.
A project revived after previous partners withdrew
The block has experienced several years of uncertainty. Former partners, including TotalEnergies, left after concluding that gas commercialisation required a clearer technical and economic solution. Main Street 1549 assumed responsibility for the block and is conducting a new environmental assessment process relating to proposed development and production activities.
Submitting an updated environmental application is an important milestone because it enables assessment of several scenarios' potential footprint. It is neither final construction approval nor an investment decision. The study must examine effects on marine ecosystems, fisheries, the coastline and affected communities, as well as incident prevention and response measures.
The production timeline remains long-term. Public estimates suggest first production around 2033, subject to studies, approvals, financing and the final investment decision. Offshore resources become commercially available only after wells, subsea equipment and transport and processing facilities are completed.
The country's energy interest
South Africa seeks to secure electricity supply and reduce coal dependence. Gas can provide dispatchable generation alongside renewable expansion and gradual closure of ageing plants. A domestic resource could also support industry if prices and volumes are competitive.
However, developing Brulpadda and Luiperd would not automatically mean affordable gas. Deepwater development costs, investor returns, transport infrastructure and purchase agreements determine the final price. Gas use in electricity generation must be compared with other industrial markets, accounting for emissions across the entire chain.
The project must also define local benefits: jobs, subcontracting, training and South African companies' participation in construction and offshore services. Local-content requirements can create industrial capabilities if procurement, skills transfer and technical needs are planned early.
A decision depending on buyers as much as technology
Choosing FLNG, a pipeline or a combination will not be purely an engineering decision. It will depend on marketable volumes, capital costs, expected prices, sales contracts and infrastructure access. Partners must also assess deepwater construction risks and the ability to mobilise suppliers with the necessary experience.
The next milestones are environmental assessment completion, selection of a preferred scenario, identification of buyers and financing structure. An investment decision can be assessed only on this basis. For South Africa, the block's potential could strengthen energy security, but its realisation depends on a credible commercial model and a transparent authorisation process.
