Parameters of wave height wave period and wave direction are essential factors in the design of marine structures but not all sea areas have all these parameters. Especially along the coast of our country there is no long-term hydro meteorological monitoring station to be able to obtain the above set of wave parameters. On the other hand most design waves are calculated based on the methods specified in the technical standards. To facilitate the application in this paper authors use wave data from the ERA-Interim global atmospheric reanalysis model developed by The European Centre for Medium-Range Weather Forecasts ECMWF . In the ERA-Interim model the wave field in the Vietnam East Sea is simulated and re-analyzed so it is necessary to study the wave characteristics along the coast of Vietnam as well as the relationship between those characteristics based on wave data extracted over a 41-year time series from 1979 to 2014. Based on wave data the authors calculated tabulated statistics and established relationships between wave characteristics for 6 typical coastal regions of our country.
