AbstractMOTAN, an inertial motion measurement system developed by the National Research Council’s Canadian Hydraulics Centre, has been used to measure ice-induced global impact forces on ships since the year 2000. Past measurements have shown that MOTAN measures whole-ship motions reliably, and that those motions can be used to determine global impact forces on ships with reasonable accuracy. This report documents more recent efforts to develop an autonomous MOTAN (autoMOTAN), i.e. a system that operates unattended during a ship’s entire operating season. The installation of the autoMOTAN on the CCGS Henry Larsen and M/T Véga Desgagnés is described. Analysis of the data measured by the autoMOTAN, in terms of the global loads, is currently underway. Those data will be included in subsequent report to provide statistical information about the magnitude and frequency of the global loads experienced by a ship during its operating season.
