Hull Flex Monitoring

SAJ Instrument produces systems that measure dynamic motions in detail, including the hull’s torsion and deflection values. Previously, the only way to measure deflection and torsion was to use strain gauges mounted in several locations on the hull. Depending on the requirements such installations can be extensive. In most cases four strain gauges are mounted on the deck to measure the hulls deflection only.

Strain gauges measures with varying result and accuracy that cannot in any easy way be compared to reality. Strain gauges are dependent on calculation based location for installation and their accuracy is thereby limited to the building process of the hull that unfortunately varies. In addition they do not measure torsion.

With a Hull Flex Monitoring System from SAJ you will get both torsion and deflection indications that are independent of steel construction errors. It can keep a continued accuracy that is better than four strain gauges. You can choose by simple indication that also include alarm possibilities in the standard system or advanced strain monitoring by adding the Mean Bending Moment module.
