Submarine cable work requires more than marine construction experience. It requires precise planning, specialized cable handling systems, engineered equipment configurations, experienced field leadership, and the ability to adapt to changing marine conditions without compromising the cable system, schedule, or safety.

CMI has successfully installed and repaired submarine power and telecommunications cable systems for clients throughout the United States and internationally. Our teams support high- and medium-voltage submarine power cable installation, submarine fiber optic cable installation, shore-end work, route clearance, post-lay burial, transpooling, repair, maintenance, and marine route development.

We understand the risks inherent in cable work: cable integrity, bend radius management, tension control, seabed conditions, burial depth requirements, vessel positioning, weather windows, environmental restrictions, and coordination with multiple project stakeholders. CMI’s equipment fleet and in-house technical capability allow us to plan and execute these operations with control and confidence.
