_D_e_t_a_i_l_s:

     In a design study for a device to generate electricity from wave
     power at sea, experiments were carried out on scale models in a
     wave tank to establish how the choice of mooring method for the
     system affected the bending stress produced in part of the device.
     The wave tank could simulate a wide range of sea states and the
     model system was subjected to the same sample  of sea states with
     each of two mooring methods, one of which     was considerably
     cheaper than the other. The question of interest is whether
     bending stress differs for the two mooring methods.
