Investigation and Study on Habitability of a Certain Type Ship

Habitability questionnaire was designed according to ship circumstance. 200 sailors who worked in two same type ships were chosen as investigation subject. The results showed that sailors subjectively regarded air quality, noise, and space as the key factors that could affect ship habitability. They thought odor, floating dust, noise, space of work area and habitation cabin odor, habitation cabin space, dishware cleanness, lavatorial odor, shower, communication of living quarters were unsatisfactory. The sailors’ demand for illuminance improved markedly when they worked on sea for several years. While the demands for habitation cabin noise, personnel density and floating dust fluctuated as working time extended.
