Title Ship Dynamics
Level MSc
UCL Credits/ECTS 30 credits

Pre-requisites
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 engineering degree obtained at a high level (2:1 or 1st class honours)) the pre-requisite units can form part of a pre-qualifying year.
Course Aims
The aim of the course is to give the student an advanced theoretical grounding in one of the fundamental analytical discipline fields of Naval Architecture and Ocean Engineering. Other fields are structural design and hydrodynamics
