A review of the Building Specification document (BS) and the General Arrangement drawing (GA) is usually the most efficient way of Human Factors intervention, in case the scope is limited.
During a review both documents are studied carefully, entirely from the perspective of the human operators. The basic question is: to what degree provides the vessels design a good environment for the crew to work and live on-board?
A review like this typically reveals a variety of results. Some examples:
- bridge contour design is blocking the officers view
- additional workplaces on the bridge are blocking the officers view
- ECR is situated in a switchboard room (not an ideal work environment for human operators)
- too much accommodation space is used for corridors
- cabins are situated on same corridors as public spaces, causing sleeping problems
- beds are not long enough to fit European sized crew
- incorrect ratio between galley size and mess size
- incorrect ratio between various cabin sizes
- workplace desktop lacks sufficient leg space
