Services
For on-site work, during vessel commissioning or at-sea operation, we normally charge a fixed daily rate + travel and per-diem expenses.
The day-rate depends on the nature of the services.
For other engineering services, we can provide fixed price quotes or work on a time and materials basis.
This depends on the nature of the project.

SonarTRX and SonarTRX-SI are software products for processing data from sidescan sonar systems, including consumer-grade fish-finders with sidescan capabilities.
The main benefit of the system is improved geo-referencing of the tow-body/sensor package during the tow.
The system also provides valuable feedback for the operators, resulting in reduced risk when towing the system close to the seabed.
LEI's solution can be used as stand-alone or in conjunction with acoustic tracking systems such as USBL to provide improved redundancy and continuity, should the USBL system fail to perform.
