CSE Mecanica e Instrumentação SA

Aker Solutions' Brazilian subsidiary, CSE Mecanica e Instrumentação SA, delivers offshore oil and gas maintenance services to clients in the exploration and production sector. Its work includes inspection, repair, and upkeep of mechanical and instrumentation systems installed on offshore platforms and subsea installations. The company focuses exclusively on the marine environment, where equipment is exposed to harsh conditions such as saltwater corrosion and high pressure. By maintaining these assets, CSE helps ensure continuous hydrocarbon flow and reduces the risk of unplanned downtime.

The subsidiary employs roughly one hundred people, indicating a modest workforce compared with the parent company's global scale. Its headquarters are situated in Brazil, allowing it to operate close to the offshore basins where its services are required. As a wholly owned subsidiary of Aker Solutions, CSE accesses the parent's engineering expertise, procurement networks, and project management frameworks while retaining operational autonomy. This structure enables the company to respond quickly to local market demands while benefiting from international best practices.

CSE's distinguishing attribute is its concentrated expertise in offshore oil and gas maintenance, a specialization that requires knowledge of marine‑grade materials, remote access techniques, and safety protocols for offshore work. This focus sets it apart from broader industrial service firms that may split their efforts between onshore and offshore projects. Within the Aker Solutions portfolio, CSE represents a dedicated unit that addresses the maintenance lifecycle of offshore assets, complementing the parent's broader offerings in engineering, construction, and field services. The subsidiary's niche positioning allows it to develop tailored solutions for specific client needs in the Brazilian offshore market.

On February 14, 2023, CSE suffered a cyber attack that encrypted files and blocked access to its IT systems, prompting the parent company to initiate containment measures including the temporary shutdown of most of the subsidiary's IT infrastructure. Aker Solutions engaged external cybersecurity experts and cooperated with local authorities to investigate the incident and restore operations. The attack was confined to CSE's systems, with no evidence of lateral movement to other parts of the Aker Solutions group. Although the subsidiary experienced operational disruptions, the broader organization worked to limit the impact on stakeholders and maintain service continuity where possible.
