    If wave energy is to become a sustainable and economic
    power source it is essential that extreme loading mechanisms
    experienced by Wave Energy Converters are well understood.
    Previous work completed at Queen’s University Belfast in
    collaboration with Aquamarine Power Ltd. highlighted slamming
    as an extreme loading mechanism experienced by pitching flap
    type devices. Testing has previously been undertaken in both 2-
    and 3-dimensional environments. This paper undertakes
    qualitative and quantitative comparisons of extreme loading
    investigations undertaken within those two environments. The
    results show that the hydrodynamics and magnitudes of slams
    experienced by the device in a 2-dimensional environment vary
    significantly from those experienced in the more realistic 3-
    dimensional environment. It is therefore undesirable to utilise 2-
    dimensional testing for extreme load quantification. It is also
    noted that visual inspection of the event (which has proven to be
    essential in identifying the hydrodynamics of many load
    characteristics observed) is significantly more difficult during 3-
    dimensional testing. As a result of the findings, ongoing research
    at Queen’s University Belfast seeks to develop a new testing
    methodology in an attempt to realize the benefits of both the 2- and
    3-dimensional experimental setups from a single experimental
    setup. The technique has been termed Pseudo-3-dimensional, or
    2½D testing. Preliminary results obtained from early tests
    undertaken are presented in this paper.
