What Tampnet does
Tampnet is a privately held Norwegian offshore telecommunications infrastructure provider founded in 2001 and headquartered in Stavanger, owned by London-listed infrastructure investor 3i Infrastructure plc. The company operates what it describes as the world's largest offshore high-capacity communication network, spanning more than 5,400 km of subsea fibre optic cable across the North Sea, Gulf of Mexico (1,700+ km), Canada, Trinidad & Tobago and Brazil, with 250,000-300,000 km² of offshore 4G coverage and growing 5G base station deployments across 120+ active sites. Tampnet connects over 350 offshore energy assets, including platforms, FPSOs, drilling rigs, service vessels, and offshore wind farms, serving customers such as Aker BP, Vår Energi, ExxonMobil Canada, LLOG Exploration and Island Drilling.
Tampnet's product portfolio spans subsea fibre, 4G/5G LTE mobile coverage, line-of-sight radio, and LEO/MEO satellite connectivity, delivered through industry-specific solutions branded as Connected Rig, Connected FPSO, Connected Vessel, Connected Platform and Offshore Wind. The company's technical differentiation centres on Private 5G with Private Multi-Access Edge Compute (PMEC), with the world's first fully autonomous offshore private 5G edge network deployed on Aker BP's Edvard Grieg platform in July 2025, alongside Distributed Acoustic Sensing and State of Polarization (DAS/SoP) fibre sensing for cable protection and AI-powered network orchestration via partnerships with Quvia, Mavenir (cloud-native 5G core), Nokia (AirScale 5G radios) and Microsoft (Azure private MEC).
Tampnet operates a subscription and managed-services revenue model anchored on long-term enterprise contracts with energy operators, supplemented by carrier services (wavelength, dark fibre, managed fibre, Ethernet, cloud connect, IP transit) sold to telecom carriers and hyperscalers through its Tampnet Carrier division, and consumer reach via roaming agreements with AT&T, T-Mobile, KPN and ODIDO plus eSIM data plans through GigSky. The company employs over 115 people across Norway, the UK, the Netherlands, the USA (Houston), Canada, Germany, Brazil and Trinidad & Tobago, and is currently expanding into offshore wind (via the 2024 dasNetz AG acquisition), AI-driven network management, and Middle East/East Africa satellite markets (via a $200M OneWeb joint venture).

Tampnet competitors and assessment
Company assessmentDirect peers
- Marlink: Marlink provides managed satellite and hybrid connectivity solutions for maritime and offshore energy customers, directly competing with Tampnet in offshore rig, vessel, and platform connectivity services. Both target offshore O&G operators with hybrid satellite/terrestrial offerings.
- Speedcast: Speedcast is a leading provider of remote communications and IT services for maritime and offshore energy, overlapping directly with Tampnet's offshore connectivity, crew welfare, and rig/vessel solutions. Both serve drilling contractors, OSVs, and offshore platforms with managed connectivity.
- GTT Communications: GTT provides global carrier services including wavelength, Ethernet, and IP transit across a tier-1 IP backbone, comparable to Tampnet's Carrier division offering managed fibre, wavelengths, and IP/Internet transit for enterprise and wholesale customers.
- PCCW Global (Console Connect): PCCW Global operates subsea cable capacity and provides carrier/wholesale telecom services globally, including wavelength and Cloud Connect, directly competing with Tampnet's Carrier services in Europe-to-Asia and transatlantic routes.
Emerging players
- OneWeb (Eutelsat Group): OneWeb provides LEO satellite connectivity to maritime, energy, and enterprise customers, and is both a Tampnet partner and a partial competitor for offshore bandwidth. Comparable in serving offshore energy with high-throughput satellite, though Tampnet operates the terrestrial/fibre layer.
- Starlink Maritime (SpaceX): Starlink Maritime delivers LEO satellite broadband to commercial vessels globally, directly competing with Tampnet for crew welfare and basic offshore connectivity budgets. An emerging disruptive peer with rapidly growing maritime footprint.
Broad incumbents
- SES: SES is a major global satellite operator providing connectivity to maritime and offshore customers via O3b MEO and GEO fleet. Overlaps with Tampnet in offshore connectivity but is a much broader incumbent across enterprise, government, and broadcast segments.
- Intelsat: Intelsat is a global satellite operator with significant maritime and offshore energy connectivity exposure via its fleet and managed services. Comparable as a connectivity provider to offshore and remote sites, though broader in scope and primarily satellite-based.
Others
- Alcatel Submarine Networks (ASN): ASN is a leading subsea cable system supplier and installer, relevant to Tampnet as a vendor and infrastructure partner. Compares as a subsea cable ecosystem participant rather than direct competitor; supplies the wet plant that Tampnet invests in and operates.
Regional players
- Cellnex Telecom: Cellnex operates telecom infrastructure including towers and small cells across Europe. Comparable as European telecom infrastructure operator, though focused on terrestrial sites rather than offshore, and serves as adjacent rather than directly competitive.
