# Module Learning Outcome Description
MLO1 Evaluate and apply basic and advanced OE technologies.
MLO2 Formulate theoretical understanding of water waves in general, both as regular and statistical processes, and apply and integrate this knowledge to the solution of ocean energy problems.
MLO3 Evaluate advanced theoretical knowledge of tidal streams and the tidal stream conversion process.
MLO4 Interpret advanced theoretical understanding of the estimation of wave forces on offshore structures and floating bodies using Morison's Equation and Froude-Krylov in the context of marine structures for ocean energy and the estimation of exciting forces on wave energy devices.techniques.
MLO5 Apply advanced theoretical hydrodynamics to model multiple body, multiple degree of freedom dynamic behaviour to estimate the dynamic behaviour of a single, and multiple, wave power devices.
MLO6 Assess and evaluate knowledge gained to several wave energy technologies for offshore and shore mounted operation, and estimate how an effective wave energy converter responds to waves.
MLO7 Design Narrow Wave tank experiments on selected devices and evaluate the results from such experiments.

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named DkIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
