(Module Coordinator)
Other Staff: E Muc-Pavic, J Aston
An advanced course in ship hydrodynamics covering the analysis
methods available for estimating ship resistance, hull/propeller interaction
effects, and the design of propellers together with methods (both
theoretical and empirical) for assessing the directional stability and
manoeuvrability of ships
Competance:As exemplified by a mechanical, civil, aeronautical or other “mechanical
type” engineering degree with strong structures element continued
throughout.
Where a candidate has demonstrated the appropriate intellectual
capability but is deemed not to have an appropriate background in
“mechanical” engineering (i.e. those with typically an electrical
st
engineering degree obtained at a high level (2:1 or 1 class honours)) the
pre-requisite units can form part of a pre-qualifying year.
