About Us

Dedicated to security of supply and embracing energy transition

We transport and process gas safely, efficiently and provide a critical link in the energy supply chain. The gas we handle helps to heat homes and power the economy. We are proud and passionate about what we do and work to make a positive difference. We support pioneering new technologies such as Carbon Capture and Storage ("CCS") and hydrogen to help unlock a net zero future for the UK.

Our Company

North Sea Midstream Partners (“NSMP” or the “Company”) is a privately-owned business that was formed in 2012 to pursue midstream infrastructure opportunities in the North Sea. NSMP’s first acquisition was the Teesside Gas Processing Plant (“TGPP”) and its second acquisition was the St Fergus Gas Terminal (“SFGT”) and associated FUKA and SIRGE pipelines which it acquired from Total in 2015. More recently, NSMP 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.

In the UK, NSMP transports and processes natural gas from North Sea oil and gas fields on behalf of its customers who are energy majors, utilities and independent producers. Gas produced from North Sea fields is transported to shore via offshore gathering or trunk pipelines (including FUKA and SIRGE) and then requires processing onshore (at terminals including TGPP and SFGT) to remove Natural Gas Liquids ("NGLs") such as propane, butane and condensate before it meets the specification for sale to end users via the National Transmission System. The NGLs that are removed are then typically sold to end users such as petrochemical companies after fractionation into separate products.

TGPP has the capacity to process around 675 million standard cubic feet of natural gas per day and SFGT around 1,270 million standard cubic feet of natural gas per day. The combined NSMP processing capacity equates to around 20% of the UK’s daily demand for gas.

In Norway, NSMP’s Risavika Liquefaction Plant has an annual production capacity of 300,000 metric tonnes which equates to the energy needs of two cities the size of Stavanger. Natural gas is transported from the Kårstø Processing Plant, to RLP through the Rogass pipelines. Following liquefaction, LNG / LBG is distributed to customers by road tankers or coastal LNG carriers.

NSMP is jointly owned by the Kuwait Investment Authority (“KIA”), the Kuwaiti sovereign wealth fund, and institutional investors advised by J.P. Morgan Investment Management Inc. The KIA’s investment is managed by Wren House Infrastructure Management (“Wren House”).

UK daily gas demand processed

We are a leading Northwest Europe based independent midstream specialist. We own nearly 600km of gas pipelines in the North Sea and supply up to 20% of UK gas demand, making ours the largest and most diversified gas transportation and processing system in the UK.

Safety, reliability and efficiency are at the heart of our business. Our zero harm policy guides everything we do from the way we manage our operations to the way we care for our communities and local environments.

We embrace an inclusive culture, working openly and in collaboration with our colleagues and stakeholders towards common goals. Diversity, equality and inclusion are embedded in our culture.

We invest in our operations and look for ways to innovate and reduce our carbon footprint. We believe gas should be generated domestically wherever possible to reduce gas transportation miles and carbon-heavy imports.

We are supporting the transition to net zero for both the UK and the North Sea. We support a leading UK energy transition project via NSMP’s ten percent (10%) interest in the Acorn Development Project (“Acorn”). Acorn is focused on Carbon Capture and Storage (“CCS”) and Hydrogen development at St Fergus, in the northeast of Scotland. Based at NSMP's 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 produced from NSMP’s St Fergus gas terminal and neighbouring gas terminals.
