Speed Through Water

Miros Speed Through Water is a breakthrough for fuel optimisation in the shipping industry, delivering reliable, real-time data with greater accuracy than traditional instrumentation without the need for any equipment immersed in water.

Accurate measurements of the speed through water of moving vessels are useful for a variety of applications including vessel fuel optimisation, hull performance, and docking and navigation in constrained areas. When considering vessel fuel consumption per day, accurate speed measurements are essential for avoiding sub-optimal speeds and large additional costs. This results from the fact that just a small variation in speed can greatly impact fuel efficiency.

Enhance ship performance and reduce vessel fuel consumption with more accurate data

None of the maintenance and installation challenges associated with equipment below the waterline

Miros Speed Through Water is a game-changer for vessel fuel efficiency and performance monitoring. From single ships to full fleets, this technology can equip shipowners and fleet managers with the data they need to run optimal operations, cut bunker-related costs, and drive down the bottom line.

“We estimate up to 10% fuel savings using Miros Speed Through Water, which is a lot!”

The challenge of accurately measuring speed through water:

  • Vessel and propeller motion, as well as air bubbles cause disturbances that lead to “noisy” data
  • Error-prone speed logs
  • Having to rely on forecast data
  • Fouling of underwater monitoring equipment
  • High installation and maintenance costs related to submerged equipment
  • Current methods lead to inaccurate vessel performance optimisation
  • Requires time-consuming calibration of submerged equipment

Miros Wavex technology introduces the following benefits:

  • More accurate measurements for input to vessel fuel consumption and performance optimisation
  • Accurate, reliable data undisturbed by vessel motion and propellers
  • More accurate current calculations when evaluating routes
  • Significant fuel consumption savings
  • No costs related to installation and maintenance of underwater equipment
  • No need for calibration using submerged reference equipment
  • Wavex can be interfaced to existing X-band radar

What is Wavex?

Wavex is a dry sensor that leverages X-band navigation radar technology for surface current measurements. The sensor delivers highly accurate real-time data undisturbed by air bubbles, turbulence or other interferences caused by vessel motion. Wavex does away with the time- and cost-related challenges of installing and maintaining underwater equipment and can be interfaced with existing marine X-band radar without any need for calibration.
