Developing a revolutionary new system for measurements under water

Area coverage | High accuracy | Easy to operate | Cost effective

SubC3D are now developing a new system for high accuracy measurement under water. A prototype has been built and successfully tested.

The problem we solve

Subsea measurements have always been far more complicated and time-consuming than performing the same measurement on shore.

All methodology of today (in the area we are addressing) requires post processing of data. This means that the client usually have to wait longer than what is planned for before the results are presented.
We intend to minimise or eliminate this waiting time.

Area of use

The system can be used where high accuracy measurements and 3D surface models are required. Distances, angles, area or volume can be extracted from the measurements. The system is perfect where high accuracy and high degree of details are needed, and for visual representation of the surveyed object.

Examples of information that can be extracted from the measurements:

  • distances
  • angles
  • areas
  • weld seems
  • pipeline inspections
  • flange details
  • volume of fish
  • lice on fish
  • wear and tear on anchor chain and fish farming nets

… and much more

SubC Eyes

– will cut cost and increase productivity
– do it faster, more detailed and accurate than what is possible with other existing system
– measurements can be done while the system or surveyed object is moving
– can be connected to ROV/AUV, used by diver or installed for permanent use
– a recording area of approximately 1 by 1 meter at 1 meter distance
– combine many recordings into one model
– operate from 0.5 meters to 3 meters
– can be adjusted to record at other distances
– the prototype will produce a 3D model containing more than 4 million 3D points for every recording

To accommodate for various lighting conditions under water the system is equipped with six different light sources. Each light source can be individually controlled from 0 to 100%.
Future models can be equipped to produce tens of millions of 3D points.
Tests onshore show that all surfaces found on subsea structures can be surveyed.
Using the prototype onshore shows that the accuracy for each individual 3D point from one single recording is better than +/- 1mm.

As in all 3D systems there is an accuracy difference in the xy-plane and the z-plane (distance from the system). In the xy-plane, control measurements have shown accuracy of +/- 0.1 mm over a distance of a half a meter.
Test under water on objects with known parameters will reveal the accuracy possible. Based on our experience from the previous systems we have developed, the accuracy under water will be close to what we can achieve onshore.
Several recordings can be combined to provide 3D models for larger structures.

Every industrial production line will have their respective requirements that have to be met. For example Oil & Gas will have a completely different production line from the Fish Farming industry. This will be met by developing different solutions for each industry based on the industry requirements.

Fish Farming

We are developing a new method for measurements in fish cages in order to improve the information available to fish farmers.

  • Biomass over time
  • Recognition of individuals
  • Monitoring of feeding
  • Detection of lice
  • Inspection of fish cages and other installations

The new sensor will have the following advantages:

  • Improved accuracy
  • More cost effective
  • Easy to use

A prototype of the new sensor is tested onshore with good results.

Sea trout measured with our new sensor. More than 300 000 3D points with an accuracy better than one millimeter.
