Abstract

The aim of the study was is to measure motions and accelerations that a vessel, during adverse sea weather conditions, suffers and produces on the subjects on board, in order to evaluate the effects on their loss of balance. A distinctive and innovative aspect of the study was to have based the research not on a simulation, for example through the use of a mechanized platform and manikins, but to have chosen a real measurement through the use of electronic instruments, partly designed for this purpose, suitable for measuring motions and accelerations of the vessel, and contemporaneously the acceleration suffered by a subject on board and free to move. The survey of the vessel acceleration and that felt by the person was carried out respectively through an inertial gyroscopic platform and a wireless triaxial accelerometer provided with MEMS sensors. This method, which provides the possibility of monitoring the vessel over a long time (a whole season) and during adverse sea weather conditions, allowed us to obtain a complete and valid data base formed by the combined action of the boat (accelerations and motions) and the system of forces felt by the subjects on board. This system of forces is the one mainly responsible for the physical stress and loss of balance in the sailor, so we can understand how this combined method of measurement, and true of the vessel motions and accelerations suffered by the worker’s body, since it allows us to identify the limit conditions which lead to loss of balance, can be used in the arrangement of measures, to guarantee the safety of the sailor
