About Us

Securing supply and embracing the energy transition
Established in 2012 as an independent midstream specialist, North Sea Midstream Partners owns nearly 600km of gas pipelines in the North Sea. Capable of supplying up to 26%* of UK’s demand for gas, our network is the largest and most diversified gas transportation and processing system in the UK.
Our first acquisition was the Teesside Gas Processing Plant (TGPP) in 2012 and our second was the St Fergus Gas Terminal (SFGT) and associated FUKA and SIRGE pipelines, acquired from Total in 2016. More recently, we established operations in Norway through the acquisition of Risavika Production AS (RPAS), which owns the Risavika Liquefaction Plant (RLP), a mid-scale Liquefaction Natural Gas (LNG) & Liquified BioGas (LBG) liquefaction plant.
Through our 10% interest in the Acorn Development Project, we support pioneering new technologies such as Carbon Capture and Storage (CCS) and hydrogen production to help the UK reach net zero emissions by 2050. Based at our St Fergus Gas Terminal, Acorn CCS will help tackle climate change by using carbon capture technology, existing gas pipelines and world class CO2 storage resources to manage emissions from industrial sites across the UK, including those from our St Fergus Gas Terminal.
We are owned by two experienced, well capitalised and long-term infrastructure investors: Wren House Infrastructure Management Limited, a global infrastructure investment manager owned and funded by the Kuwait Investment Authority, and institutional investors advised by J.P. Morgan Investment Management Inc.


Our operations
In the UK, we transport and process natural gas from North Sea fields for energy companies, utility companies and independent producers.
We transport the gas to shore in trunk pipelines and process it at our terminals to remove Natural Gas Liquids (NGLs), so that it meets the specification for sale to end users via the National Transmission System. After fractionation into separate products, the removed NGLs (propane, butane and condensate) are sold to end users such as petrochemical companies.
Our Teesside Gas Processing Plant can process around 675 million standard cubic feet of natural gas per day and our St Fergus Gas Terminal can process around 1,270 million standard cubic feet of natural gas per day. Between them they deliver around 20% of the UK’s daily demand.
In Norway, our Risavika Liquefaction Plant can process 300,000 metric tonnes a year. The natural gas from the Kårstø Processing Plant is transported to RLP through the Rogass pipelines. Following liquefaction, LNG / LBG is distributed to customers by road tankers or coastal LNG carriers.
