Subsea infrastructure refers to the complex network of pipelines, cables, equipment, and facilities installed on or beneath the ocean floor. This infrastructure is essential for supporting offshore oil and gas extraction, telecommunications, and power transmission. It includes components such as wellheads, manifolds, pipelines, and control systems, all designed to operate in harsh underwater environments. Protecting subsea infrastructure from physical damage, environmental hazards, and cybersecurity threats is crucial, as disruptions can have significant economic and environmental consequences. The increasing reliance on digital control systems makes cybersecurity a key concern for maintaining the integrity and availability of these critical assets.
