North Sea Midstream Partners

What North Sea Midstream Partners does

North Sea Midstream Partners (NSMP) is a privately held midstream gas infrastructure operator established in 2012 and headquartered in Aberdeen, with its primary legal entity registered in Jersey. The company owns and operates five integrated core assets in and around the UK North Sea and southern Norway: the SIRGE Pipeline (234km, 665 mmscf/d capacity), the FUKA Pipeline (362km, 1,271 mmscf/d capacity), the St Fergus Gas Terminal, the Teesside Gas Processing Plant (675 mmscf/d processing capacity), and the Risavika Liquefaction Plant (300,000 metric tonnes/year LNG/LBG capacity). In aggregate, NSMP's network can supply up to 26% of UK daily gas demand and processes gas from 35 connected fields. All major assets have maintained availability above 99% for multiple consecutive years.

NSMP generates revenue through midstream tolling services — gas transportation and processing — provided to upstream oil and gas producers and utility companies under bilateral Transportation and Processing Agreements. New capacity requests are initiated through a formal Service Request process followed by Capacity Access Agreements. The company does not own upstream gas production; it earns fees for moving and processing third-party gas, fractionating natural gas liquids, and liquefying natural gas and biogas. It also holds a 10% stake in the UK Government Track 2 Acorn Carbon Capture & Storage project at St Fergus, positioning it within the energy transition value chain.

NSMP is owned by Wren House Infrastructure Management Limited (a subsidiary of the Kuwait Investment Authority) and institutional investors advised by J.P. Morgan Investment Management Inc. Operations are managed by px Group as operating partner. The company operates with a workforce of more than 1,000 across its UK and Norwegian sites and holds ISO 9001, ISO 14001, and multiple consecutive RoSPA Gold Awards, including a Patron's Award for TGPP in 2024.

Revenue model

1. Gas Transportation and Processing Tolling: NSMP provides midstream tolling services to upstream shippers — transporting and processing third-party natural gas through its pipeline and terminal infrastructure in exchange for fees. The company does not own upstream production; its revenue is derived from capacity-based charges for processing, transportation, and liquefaction services. Feed gas from multiple fields flows through NSMP infrastructure; NGLs are fractionated and sold to end users.

Expansion highlights5 records

Direct peers

• Spirit Energy: North Sea-focused upstream operator (Centrica-backed) producing into NSMP-served infrastructure. Spirit is a peer because it sells gas through the same UK midstream system and competes for capacity on FUKA, CATS and Breagh pipelines.
• Harbour Energy: Largest UK-independent North Sea producer and Acorn CCS JV partner with NSMP. Harbour is both a major shipper on NSMP's pipelines and a partner in transition infrastructure, making it one of the most directly comparable participants in the North Sea midstream value chain.
• Neptune Energy: Independent upstream operator with North Sea production tied into NSMP's processing and pipeline network. Comparable as a North Sea-focused E&P that relies on and co-invests in shared midstream infrastructure.
• INEOS Energy: Holds 18.26% of NSMP's SIRGE Pipeline and operates its own North Sea production feeding NSMP infrastructure. INEOS is both a co-owner in NSMP assets and a competitor/customer in midstream services, making it a directly comparable integrated North Sea player.
• Perenco: North Sea operator with significant offshore production that relies on third-party midstream infrastructure including pipelines and processing in the southern and central North Sea. Closely comparable as a shipper dependent on shared UK midstream assets.

Broad incumbents

• National Grid plc: Owns and operates the UK National Transmission System to which NSMP's St Fergus and TGPP deliver processed gas. National Grid is the upstream buyer/balancing party for NSMP's output and is the most relevant adjacent operator in UK gas transportation infrastructure.
• Cadent Gas: Largest UK gas distribution network operator, part of the same UK gas value chain as NSMP. Comparable in operating gas infrastructure under regulated framework and is a downstream offtaker of NSMP-processed molecules via the National Transmission System.
• SGN (Scotia Gas Networks): Owns and operates gas distribution networks in Scotland, southern England and Northern Ireland, including connections in the Aberdeen/St Fergus catchment. Directly comparable as a UK gas infrastructure operator serving end consumers from NSMP-fed supply.
• Equinor: Norwegian major with extensive North Sea pipeline infrastructure and LNG operations (including Hammerfest LNG) analogous to NSMP's Risavika Liquefaction Plant. Comparable as a major integrated operator of gas transportation and processing infrastructure in the same North Sea basin.

Others

• Wren House Infrastructure (Kuwait Investment Authority): NSMP's majority owner and a global midstream/infrastructure investor; comparable as a peer capital provider and operator of similar pipeline and utility-scale energy assets worldwide, including other North Sea and European midstream platforms.
