Regulatory Landscape and Standards (e.g., IEEE, IEC)
The regulatory landscape governing Subsea Cable Basing Alignment Systems is rapidly evolving as the demand for international data connectivity and offshore renewable energy infrastructure accelerates into 2025 and beyond. Robust standards are essential to ensure system reliability, interoperability, and safety in the challenging subsea environment.
On the international level, the International Electrotechnical Commission (IEC) continues to play a pivotal role in developing and updating standards for subsea cable systems. The IEC 60092 series, which addresses electrical installations in ships and offshore units, remains fundamental for cable system alignment and installation. In 2024 and 2025, working groups within the IEC Technical Committee 18 (TC 18) are reviewing and revising guidance documents to address emerging technologies, including precision alignment systems and automated cable laying solutions.
The Institute of Electrical and Electronics Engineers (IEEE) also maintains influential standards. The IEEE 1120 standard, which covers the installation practices for cable systems in marine environments, is under periodic review to incorporate advances in dynamic positioning and remote-operated vehicle (ROV)-based alignment—a technology increasingly deployed by leading industry players. The IEEE has encouraged stakeholder input in 2025 to ensure alignment protocols reflect the latest in sensor technology and digital mapping.
National regulatory authorities, such as the UK’s Marine Management Organisation and the US Bureau of Safety and Environmental Enforcement (BSEE), continue to align their permitting and oversight requirements with these international standards. In some jurisdictions, regulators are initiating pilot programs requiring real-time data reporting from subsea cable alignment systems, a move aimed at increasing transparency and reducing installation risk.
Industry alliances, such as the International Cable Protection Committee (ICPC), have intensified collaboration in 2025, publishing updated best practices for cable route planning and alignment based on both IEC and IEEE frameworks.

Challenges in Subsea Cable Basing and Alignment Operations
Subsea cable basing and alignment operations are critical for the successful deployment and long-term reliability of undersea communication and power transmission networks. As global data demand accelerates into 2025 and beyond, the scale and complexity of subsea network projects are increasing, bringing forward several technical and operational challenges for cable basing alignment systems.
One primary challenge is seabed variability. Modern cable routes traverse increasingly complex marine environments, including deep ocean trenches, tectonic plate boundaries, and areas with dynamic sediment flows. Variability in seabed composition—such as rock outcrops, soft sediments, and shifting sands—requires precise, real-time cable positioning and advanced route planning. Leading system providers like Oceaneering International, Inc. and Saab have responded by developing high-resolution sonar, LIDAR, and autonomous underwater vehicles (AUVs) to enhance seabed mapping and alignment accuracy, but integrating these tools into seamless cable-laying workflows remains a technical hurdle.
Another ongoing challenge is the alignment of cables during dynamic vessel movement. Cable-laying ships must maintain precise heading and speed despite unpredictable ocean currents and weather conditions. Dynamic positioning (DP) systems, such as those offered by Kongsberg Maritime, play a vital role, but even minor deviations can cause cumulative alignment errors over long distances. As cable projects grow longer and traverse harsher environments, the need for robust, real-time feedback loops between DP systems, cable tensioners, and seabed-mapping sensors is intensifying.
Human and environmental safety is also a central concern. The deployment of cables in ecologically sensitive or heavily trafficked maritime areas requires advanced alignment systems that minimize seabed disturbance and avoid hazards. Companies like Nexans have integrated environmental monitoring and cable tracking technologies into their deployment fleets to address these issues, but the coordination between regulatory compliance, environmental stewardship, and operational efficiency remains a balancing act.
Looking ahead, the industry is moving toward greater automation and digital integration. Real-time data fusion from multiple sensors, machine learning for route optimization, and remote operation capabilities are expected to improve alignment accuracy and reduce risks. However, interoperability between diverse hardware and software platforms, as well as cybersecurity for these connected systems, presents new layers of complexity that the sector must address in the next few years.
Overall, while technological advancements are improving the precision and reliability of subsea cable basing alignment systems, the evolving operational environment and elevated project demands are ensuring that challenges will persist—requiring continuous innovation and collaboration among industry leaders.
