Submarine Cable Inspection & Testing

Canpac Marine offers comprehensive submarine cable inspection services utilizing our commercial dive teams with handheld cable trackers, video, and USBL diver beacons. Our ROV’s can be outfitted with TSS cable trackers, high-definition cameras, and other inspection tools. All of our inspection teams have the capabilities to communicate with shore-based client engineers through live video conferencing, allowing the client to see their subsea assets in real time.

  • Our work-class ROVs, rated for depths up to 6,000 meters, are equipped with high-resolution cameras, sonar systems, and manipulators. These features allow for precise visual and sonar-based assessments of submarine cables in diverse underwater environments.

  • Our commercial dive teams are highly experienced in near shore cable inspections. Equipped with surface-supplied air systems and underwater communication devices, they provide:

    • Visual inspections of cables and related infrastructure in shallow water environments

    • Hands-on anomaly detection and repair assistance

    • Support for shore landing construction and maintenance

    The divers work closely with engineers and project managers to ensure high-quality inspection results and timely completion of tasks.ext goes here

  • All of our dive and ROV teams provide real-time video and audio feeds to engineers and client representatives on shore during inspections. This ensures efficient access to inspection data and facilitates faster decision-making by:

    • Allowing clients to speak directly to ROV and Diver Superintendents during inspections

    • Reducing the likelihood of incomplete or missing data

    • Eliminating the need for costly re-inspections after client review

  • We utilize specialized tools, including TSS cable trackers and burial depth measurement systems, to accurately determine the burial depth and positioning of submarine cables. This ensures compliance with design specifications and enhances cable protection.

  • Item descriptionOur advanced monitoring systems are capable of detecting a wide range of issues, including:

    • External damage from trawling or anchors

    • Cable exposure or insufficient burial

    • Joint failures or other structural anomalies

    By identifying these issues early, we help clients implement timely maintenance and repairs, reducing long-term risks and costs.

  • For both power and fiber optic cables, we offer comprehensive in-situ testing services, including:

    • Electrical integrity testing

    • OTDR (Optical Time-Domain Reflectometry) testing

    • Insulation resistance measurement

    These tests ensure the reliable performance of submarine cables and provide critical data for long-term asset management.

  • During inspections, we collect data on:

    • Seabed conditions

    • Marine growth on cables

    • Environmental changes that could impact cable integrity

    This information supports proactive maintenance planning and environmental compliance.
