Automatic Draught Indicator

    Weir-Jones Engineering offers an innovative method for vessel draught measurement by accurately defining the position of the water plane in real- time. This is a truly non-invasive draught measurement technology, and is known as Automated Draught Indicator System, or ADIS™.


  • Pipeline Strain Monitoring
    Monitoring Undesirable Movement

    Pipelines, in many parts of the world, cross unconsolidated deposits. The downslope soil movement causes the development of tension and compression traction forces on the upper and lower pipeline sections.  Weir-Jones is able to implement various types of strain monitoring systems enabling pipeline operators to detect even the slightest deformation of a pipe caused by the movement of the surrounding soil.

  • RockFall™
    Seismic Rockfall Detection System

    Weir-Jones Engineering Consultants has developed the Seismic “Rockfall™” Detection System (SRFDS) which is an evolutionary alternative to traditional slide fence technology. This revolutionary system relies upon acoustic signature recognition to determine if and when rocks or other hazardous debris fall onto the right of way.


  • ShakeAlarm®
    Earthquake Early Warning System

    ShakeAlarm® is a cost-effective, highly reliable Earthquake Early Warning System (EEWS) which provides critical minutes or seconds of warning in order to minimize loss of life and assets. This is done by recognizing and quantifying the faster, but lower energy, P (compressive) wave which is the precursor of the more damaging S (shear) wave.
