The theories developed to optimise the functioning of wave energy devices of the "oscillating float ' type lead to increased knowledge which goes well beyond the narrow domain of energy production by waves.

In particular the general expression for the energy transmitted from waves to a floating device may be exploited with advantage to give an energetic interpretation of the functiannning of several ocean structures.

In this presentation the following examples are chosen far the development:

We shall also mention other examples for which the theory of energy production from waves can be used with advantage : wave generators which do not need beach dampers behind them, wave generators of absorbing type (SALTER licence), floating breakwaters, and ships with perforated ballasts.
