WISE Doppler Current Log System

Optimised oil spill recovery and maritime towing efficiency.

The WISE Doppler Current Log measures the speed through the water of towed devices such as oil recovery booms or skirt booms. Built for harsh marine environments, it gives real-time data to optimise towing speed, improve operational efficiency and reduce environmental impact.

Key features

Accurate speed measurement

Precise towing speed, to optimise oil recovery operations.

Robust design

Built to handle the challenges of the marine environment.

In-sea and on board

In-sea and vessel-mounted components work together for data collection and visualisation.

System overview

How the system is put together

The measurement is made in the sea by a buoy-mounted sensor and sent by radio to the vessel, where it is displayed for the people running the tow.

In the sea

In-sea components

  • Doppler Log Buoy, with a radio transmitter and antenna (870 MHz) for reliable data transmission
  • Doppler Log Sensor (ADCP), for precise measurement of water speed
  • Underwater cable, with strain relief and secure connectors for uninterrupted operation

On the vessel

Vessel-mounted components

  • Receiver unit, receiving data from the buoy, with master and slave configurations
  • WISE Doppler Log Software, displaying real-time data for operational decisions
  • Receiver antenna, on a secure rail bracket for stable reception
  • Waterproof cases, for safe transport and storage

Applications

Wherever the speed of a towed device through the water decides how well the operation works.

  • Oil spill recovery: minimise spillage and maximise efficiency during critical recovery operations.
  • Environmental monitoring: accurate towing data to support compliance with environmental standards.
  • Maritime towing: monitor towing speed in real time to optimise vessel operations.

In the field

Proven in demanding conditions

The Doppler Current Log has been deployed in demanding environments, including on specially designed buoys for towing applications.
