Anyone understand the commercial structures for the Export of LNG from Canada to Asia?

Hey all,

I'm trying to wrap my head around the commercial and corporate structures for exporting Canadian LNG to Southeast Asia, specifically in the context of long-term Sales & Purchase Agreements (SPAs).

I understand the role of the off-taker (buyer), but I'm looking for clarification on the Canadian side, particularly how project structures like these apply:

• Equity-lift: shared ownership & self-marketing.
• Tolling: service-fee model with stable returns.
• Merchant: project bears all market risk for potentially higher rewards.

My main point of confusion is the specific difference between an LNG Producer and a Developer within these models. In a typical long-term SPA structure, which of these parties is the hypothetical "exporter of record" in Canada, and how does that role change depending on which of the three models above is being used?

From my initial research, it seems projects like LNG Canada involve joint ventures with multiple international partners (Shell, Petronas, etc.). Does one entity within the JV act as the developer, and the JV itself become the producer/exporter? Or do the individual partners take on different roles (e.g., some tolling, some equity-lift)?

Any insights from someone with experience in these large-scale energy contracts would be hugely appreciated!

Thanks in advance.
