Prenormative guidelines and standards for comfort rating

Ship designers, operators, and classification societies recognize the positive impact of comfort requirements on the overall well-being of passengers. To provide criteria that will assist in improving comfort of passengers onboard passenger vessels, classification societies have been developing guidelines with the objective of defining comfort requirements for passenger ships.

There are five categories of comfort criteria that may be controlled, measured and assessed in passenger spaces on vessels: accommodation design, indoor climate, lighting, noise, and high and low-frequency whole-body vibration. Low-frequency whole-body vibration is caused by ship motions, and these ship motions induce motion sickness, fatigue, and a degradation of motor tasks. Because of the complexity involved, the assessment of low-frequency whole-body vibration has, until now, not been considered.

To overcome this difficulty, criteria based on rational standards are needed for assessing low-frequency whole-body vibration relating to passenger comfort on board ships.

Results of Task 5.3 will consist of rational standards for human comfort on board ships. Such standards serve to establish prenormative guidelines for rule development, specifying rating levels of acceptability. The following categories of passenger motion comfort are to be defined: pleasant, acceptable and uncomfortable.
