Smart Brine Viewer


An innovative solution that optimises the freezing process in brine or the conservation in RSW.

sonde cuve tunel 1 - Products

Thanks to its network of probes installed in each of the tanks, the SBV system collects data from the conservation process, which will be processed by an algorithm specifically developed for the SBV and protected by a patent.


The data supervision is carried out through the IHM SBV software program, which offers:

An overview of all the tanks that shows the condition of each individual tank: empty, in sea water, in brine; the temperature, the mass concentration of salt and the liquid freezing point.

A specific view per tank detailing the evolution of the temperature, the mass concentration of the liquid and the freezing point of the liquid in graphical form.

The SBV system makes it possible to monitor the seawater refrigeration and brine freezing processes from fishing to landing. It also makes it possible to identify fish batches stored in optimal conditions.

The system benefits are:

  • fuel - ProductsSave fuel oil and salt by precisely knowing the salt concentration of the brines
  • fish - ProductsImprove the fish quality
  • snowflake 1 - ProductsControl the freezing in brine
  • danger - ProductsReduce the risk of technical failure in refrigeration systems and the downgrading of fish batches
  • opportunities - ProductsSeize new market opportunities

The system includes :

  • Temperature probe
  • Conductivity probe
  • Stainless steel Carter
  • Industrial cabinet
  • Data center
  • Touch screen
  • Supervising software program (IHM)

Temperature probe

The measurements collected by these probes make it possible to determine:

  • the temperature inside the tank (dry or filled with liquid)
  • the liquid mass concentration of salt
  • the liquid freezing point
  • the temperature at which the dihydrate appears

These probes meet high-precision metrology standards and have been selected to withstand the restrictive environment of the vessels and the freezing and refrigeration processes.

Data collection and processing, supervision of the freezing process

armoire 1 - Products

Industrial cabinet

The network of cables coming from the different tanks of the vessel converges towards the industrial cabinet, designed to collect the continuous flow of information, while avoiding any disruption, damage or signal break. This industrial quality cabinet can accommodate data from sensors up to 24 tanks.

Thin client and touch screen

Thanks to the thin client and the touch screen installed in the laptop, the operator supervises the temperature and salinity parameters of the different tanks of the vessel and their evolution during the tide in real time.

data center 1 - Products

Data centre

Then, the information flow is sent to the data center in which the data are time-stamped, processed and protected by encryption. Server and data security are ensured by the system architecture, redundancy and protection against electric shocks. The information can be accessed from any ethernet network point on the vessel by installing the software on laptops at different places on the ship (gateway, cabin…). Optional: Regular satellite exports allow the shipowner to see the freezing and/or refrigeration parameters of his fish loads by vessel and for his entire flotilla..

Innovative development resulting from the R&D carried out by Olen

glace - Products
algorithm - Products


Olen’s metrological research was triggered by the fact that no system was able to display the salinity of brine or seawater in the refrigeration and freezing processes used in the fishing industry. This is how a specific algorithm for processing data from SBV sensors has been developed.

Algorithme olen - Products

This algorithm determines the salinity of the brine at positive and negative temperatures and at each stage of brine ageing. It also defines the freezing point of the brine, an essential information in the cold descent process to determine a target temperature and avoid any risk of damage on the on-board refrigeration systems.

software development - Products


The IHM SBV software has been specifically developed to meet the needs of the technicians involved in the cold control inside the ship’s tanks and to make full use of SBV technology.

Thanks to its interfaces, the technician can monitor the temperature in each tank, the mass concentration of salt in the brine or seawater, as well as the freezing point value of the liquid.
