This page provides information on wave heights and sea states that may be relevant for an oil spill response operation.

Significant wave height: Commonly used as a measure of the height of ocean waves. Indicated by the notation Hs.

Maximum wave height: 1 in 100 waves will be more than 50 % higher than Hs, 1 in 1000 waves roughly twise Hs.

See e.g. https://en.wikipedia.org/wiki/Significant_wave_height for a full description.
