Objective and subjective criteria for assessing the light environment in vessel spaces: Application and comparison

Abstract

[Abstract]: Fatigue is a major factor in human error, which in turn a ects maritime accident rates. For this reason, conditions in the light environment present in the ship?s work and rest areas can play a role in causing fatigue among crewmembers. This paper assesses conditions in the light environment within the spaces of a roll-on roll- o vessel. Objective factors, measured over a two-year period at sea during the vessel?s operation, are contrasted with subjective aspects, reflected in surveys about the ship?s environment. Moreover, this article compares the results of this assessment with the implementing regulations for professional activity on land is similar to the on-board work examined here.
