International Competence Center for Subsea Production Controls
OneSubsea GmbH, based in Celle, is an international competence and technology center for Subsea Production Controls, developing, manufacturing and testing high-tech control systems for complex production facilities deployed in water depths of up to 3,000 meters for the extraction of crude oil and natural gas. The company is part of the global corporation Schlumberger (SLB) and operates in the field of special machinery engineering and automation technology. Core products are the Subsea Control Module (SCM), the Master Control Station (MCS) including software, as well as Subsea Distribution products and Subsea Landing String Controls. Value creation takes place in the areas of engineering, supply chain, production, project and quality management, and customer service. Customers are the world's leading oil and gas companies (majors and supermajors), national oil companies, and independent producers. In addition, the company is building a second pillar in the New Energy sector and is a member of the AquaVentus initiative, which aims to produce green hydrogen from offshore wind energy by 2035.

Quality and Testing Technology
The products are subject to the highest quality requirements so that the equipment can remain on the seabed for up to 25 years without maintenance. In the company's own test bay, they undergo strict checks in the high-pressure chamber (Hyperbaric Chamber) and by X-ray before delivery.
