This paper focuses on problems related to the analysis of maritime work domains using the abstraction hierarchy proposed by Rasmussen (1986). It is argued that there is need for a causal basis of the means-end relations of the abstraction hierarchy. The main reason for this is that an account of the possibilities offered by physical objects, denoted as means, depend not only on the intrinsic properties of such objects but also on the properties of causally related objects in their immediate environment. This is particularly obvious in the maritime domain where the forces produced by control devices (e.g. main propeller, rudder and thruster), and disturbances (e.g. wind and current) are highly dependent on external properties of the water, hull, etc. Through simple causal models of control devices it is illustrated that objects typically denoted as means corresponds to an individual physical object having specific causal propensities in the context of an action involving additional objects (having other causal propensities). When adopting a means-end view such additional objects would normally be backgrounded.
