Light Class Autonomous Underwater Vehicles (AUV)

Autonomous or unmanned survey vehicles are proven to positively impact your offshore projects by reducing cost, schedule, risk and logistics.

The new generation of light-class AUV have furthered these benefits without any compensation of data accuracy, resolution or quality.

AUV systems are safe and reliable:

  • Low logistics, lightweight and portable
  • Reduced offshore staffing requirement
  • No complex lifting/recovery systems required
  • Obstacle avoidance through forward looking sonar
  • Shore launch/recovery possible
  • Battery powered
  • 300+ systems globally predominantly in defence and academic sectors

AUV systems are efficient:

  • Significantly reduced costs compared to larger AUV / ROV operations
  • Operate from smaller vessels reducing project costs
  • Operates effectively in shallow water environments
  • Rapid mobilisation and demobilisation
  • Rapid in-field servicing
  • Single pallet transportation

AUV systems are flexible:

  • Dual frequency side-scan sonar (600/1600 kHz)
  • Phase differencing bathymetric sonar (600 kHz)
  • Water quality sensors (e.g. CTD, turbidity, DO, pH, oil, rhodamine)
  • Digital camera and strobe
  • Towed magnetometer

Subsea Gliders

JV partner, Blue Ocean Monitoring, have extensive experience in the deployment and management of long-range and long-duration glider technologies.

Autonomous gliders are extremely cost-effective in comparison to vessel-based monitoring campaigns, provide exceptional data quality and have minimal health, safety & environmental implications.

Blue Ocean Marine Services AUV Gliders.

Glider systems are safe and reliable:

  • Practical, lightweight and portable
  • Minimal staffing and vessel requirement
  • No complex lifting/recovery systems required
  • Shore launch/recovery possible
  • Battery powered
  • Worlds most prolific underwater glider platform, predominantly used in defence and academic sectors.

Glider systems are efficient:

  • Highly economic survey platform
  • Data provided in near real-time through satellite telemetry
  • 2-way communication and control
  • Buoyancy propulsion allows deployment of weeks/months
  • Rapid mobilisation and demobilisation
  • Modular sensor payload

Glider systems are flexible:

  • Water quality sensors (e.g. CTD, turbidity, DO, pH, oil, rhodamine etc.)
  • Hydrocarbon sensors (Oil, methane etc.)
  • PAM Hydrophones (PAM)

Metocean and Environmental Surveys

A good understanding of metocean (meteorological and oceanographic) data is fundamental to the success of all offshore projects as this information will serve to characterise the available resources, the design requirements for survivability of the project and the strategy for maintenance and accessibility.

 

Our metocean capability extends to the in-situ monitoring of directional and non-directional waves and current flows (single-point and profile), water levels, water quality measurements (dissolved oxygen, pH, turbidity, salinity, chlorophyll etc.) and meteorology. We have knowledge in both stand-alone and bespoke real-time systems with experience in a diverse range of data communication and telemetry systems.
