A consortium of six global investors has entered into a $20.7 billion agreement with Abu Dhabi National Oil Company (ADNOC), the state-owned oil company said Tuesday.

As part of the agreement, the group will invest $10.1 billion to acquire a 49% stake in a newly-formed subsidiary, ADNOC Gas Pipeline Assets, with lease rights to 38 pipelines. ADNOC will hold the majority stake of 51% and will retain ownership of the pipelines. It will also manage operations and remain responsible for capital expenditure, according to CNBC.

It is the single-largest energy infrastructure investment in the region, and the largest in the world in 2020, according to Abu Dhabi National Oil Company. It is also part of the UAE national oil company’s strategy to attract foreign capital and maximize the value of its assets.

The six companies involved are Global Infrastructure Partners, Brookfield Asset Management, Singapore’s sovereign wealth fund GIC, Ontario Teachers’ Pension Plan Board, NH Investment & Securities and Snam.
