From 1 January 2026, new container ships and bulk carriers of 3,000 GT and upwards must be fitted with an electronic inclinometer. The requirement comes from amendments to SOLAS regulation V/19 adopted by the IMO.
The inclinometer has to determine, display and record the ship’s roll motion. Traditional bubble and pendulum inclinometers react to the ship’s accelerations, so on a rolling vessel they can show heel angles that are too high. An electronic inclinometer shows the true inclination and roll period.
Because the data is passed to the VDR, the instrument must be type-approved to the IMO performance standard MSC.363(92). Existing ships are not covered by the new rule, but an electronic inclinometer can also be retrofitted.
We supply two electronic inclinometers from the Cassens & Plath range: the EPR EI-1 and the NAVITRON NT1750 EPR. Both are type-approved for SOLAS ships and work on slightly different principles – we will help you choose the one that suits your vessel.
