Patrolling Subsea Surveillance

Surveillance of remote and long-range seabed infrastructure is a challenge

Seabed infrastructure stretching across oceans and borders is a potential target for hostile activities. In addition to other means of surveillance, regular patrolling by long-range Autonomous Underwater Vehicles (AUVs) contributes to Critical Subsea Infrastructure Protection.

The solution is a submerged and autonomous patrolling vehicle with high-resolution observation capabilities

The HUGIN AUV represents best-in-class autonomous subsea surveillance capability. It is ideal for patrolling and inspecting pipelines, power lines and communication cables and other subsea structures. The HUGIN AUV can patrol up to 2,200km in one mission and operate down to depths of 6000m. The operation can be supported either from a surface vessel or from shore. The HUGIN AUV sensor package combined with surface processing makes it an effective tool for high resolution underwater observation, to maintain the integrity of subsea infrastructure.

We provide...

- Detection, identification, and classification of man-made objects on the seabed
- Detection of anomalies or changes on the seabed
- Operational at water depths down to 6 000 m
- Long endurance, battery operated
- Unprecedented sensors package
- Field-proven, high reliability

Subsea Pipeline Patrol Uncovers Potential Threat

A Hugin Autonomous Underwater Vehicle (1) is patrolling a vital subsea pipeline on the seabed. It discovers an object in the previously mapped seabed next to the pipeline. When the Hugin resurfaces, operators check the data and see that it looks like an explosive device.

They check the KSAT satellite feed (2) on their Integrated Maritime Awareness Interface (3) and discover that six ships have crossed close enough to the site in the time since the last patrol. One of these vessels was sailing without the Automatic Identification System (AIS) and has therefore become the prime suspect.

The system identifies the vessel that turned off its AIS, and operators immediately alert all necessary authorities to apprehend the vessel and investigate the explosive device.
