Port & Bridge Inspection | ROV Cable | Flexible Structure | Easy Deployment Solution
Our ROV Cable is engineered for offshore and nearshore inspection projects, providing a combination of flexibility, abrasion resistance, and long-term reliability. Its reinforced yet lightweight construction allows smooth navigation around pilings, piers, and confined underwater structures. Available in multiple core configurations, including power-only, hybrid signal, and fiber-optic variants, this cable supports high-current operations, real-time video, and sensor telemetry. With neutral buoyancy or slightly negative profiles, it minimizes drag and ensures stable deployment for multi-day inspection missions.
