Ship motion affects comfort of passengers. Although ISO2631-1:1997 offers guidelines for acceptable acceleration
levels, these guidelines assume continuous vibration, characterised by relatively low levels of jerk, i.e. the time
derivative of acceleration. New generations of ships, however, are causing irregular series of distinct events
characterised by relatively high jerk levels. In the recent past, the maritime industry showed a renewed interest in
properly understanding the implications of these jerk events on the comfort of passengers onboard vessels. However,
detailed knowledge of the physics of the phenomenon and of the sensitivity to it of the human body is lacking, as do
univocal acceptability criteria of jerk levels perceived onboard ships.
MARIN and TNO will collaborate and share their expertise to study in detail how jerk is experienced onboard vessels by passengers and to understand if jerk represents indeed a degradation of the comfort level. In this document a proposal for a Joint Industry Project is made.
