Totem Plus Hull Stress Monitoring measures and analyzes important parameters affecting Hull Stresses on ships. Such parameters include Bending moments, Pitching, Rolling and Pounding. Alarms are given if any parameter deviates from the allowed region, and correlations between parameters are easily obtained. Online transverse stability (GM) is measured and displayed from the rolling period, and parametric rolling probability is calculated based on actual roll and pitch parameters. The system should be used in order to give useful information to masters on possible actions such as ballasting, changing course etc. The system is based on dedicated sensors such as Long Based Strain Gauges (innovatively designed by Totem Plus – see picture), Accelerometers (measuring Pounding and Slamming) and inclinometers. The Hull stress monitoring can be integrated with a stress and stability software (recommended).
