The traditional approach to the study of human factors in the maritime work domain is the analysis of accidents. These analyses provide valuable information, but they are not sufficient to get insight in the causal relationship between factors that shape performance and actual human performance in everyday routine work in the maritime domain is the quasi-experimental field study where variations in performance can be observed as a function of natural variations in performance shaping factors. This paper demonstrates how these natural variations of workload demand very easily can be observed as a function of the different stages or phases of a voyage on one out of four selected Roll-on Roll-off (Ro-Ro) ferries in regular service. A very simple method for measurement of communication at the bridge of the ship is suggested. This method was used in a pilot study of the relationship between workload and attention and some interesting mechanisms were found. These findings could lead to development of hypotheses about the causal relationship between workload and attention, and the hypotheses could be tested by means of quasi-experimental field studies as suggested in this paper.
