Our Story
4Subsea is a leading provider of technology and services that help operators optimise energy production from subsea oil & gas fields and offshore wind farms. We combine domain expertise with data analytics and digital services to maximise lifetime of assets, reduce operational cost and optimise future projects through data-driven design.
Where Our Journey Began
4Subsea was founded in Norway in 2007, built on the belief that engineering expertise and digital innovation together could solve some of the industry’s most demanding challenges.
What began as a small group of engineers has grown steadily in both capability and scale. Today, we are over 190 employees with headquarters in Asker and offices in Bergen, Kristiansand, Stavanger,
Rio de Janeiro, Kraków and Aberdeen.
We support major energy operators – as part of the Subsea7 Group.
Why We Exist
Born in a country defined by the North Sea, we understand what it means to operate in harsh, weather‑exposed offshore environments.
Around the world, operators face similar pressures – safety, performance and sustainability.
We deliver critical decision support to energy providers, enabling lifetime extension of assets and operational uptime. We combine our operational experience with digital capabilities to automate engineering processes and help operators reduce risk and cost.
Turning Data Into Actionable Insight
Our portfolio of retrofittable, autonomous sensors help operators reduce cost of operations and maximise life of assets, by using the sensors in combination with advanced algorithms, data analytics, and specialist engineering competence.
With 4insight® operators can “know it before it happens” – and act accordingly, thus preventing costly repairs or production shutdown.
A Powerful Trio
We bring together three complementary strengths to deliver an end‑to‑end solution for offshore operators:
Domain expertise
Our engineering capability is rooted in deep subsea knowledge and hands‑on offshore experience. We’ve worked onboard the rigs and vessels, handling tasks such as installing risers, drilling wells, managing wind turbine installations and cable laying.
State-of-the-art sensors
Reliable decisions require reliable data. Our sensor technology – inspired by medical cybernetics, mobile innovation and IoT – delivers high‑quality measurements even in the harshest environments.
Software & Data Insight
Our software developers and data scientists turn complex data into actionable insight. Using analytics, modelling and digital twins, our digital platform guides operators on when, where, and how to take informed action.
4Subsea is a small company, with much flexibility and interesting tasks. I have very talented colleagues who are always willing to teach. I can immerse myself in and spend time to understand the issues I shall address. Heidi Gryteland Holm
