The Study of the Sea State Data Collected from Bay of Bengal During 1964-65

Abstract

The wave data collected on board INS K1STNA from Bay of
Bengal during July to August, 1964 and January, February and
April, 1965 are presented. The wave parameters are analysed and
given in a form most suitable for model testing of ships. The variation
of wave height with Beaufort number is remarkable. Wave
periods from 2 to 10 seconds are observed with maximum frequency
in the range of 2 to 5 seconds. The heights and period obtained are
compared with those obtained by previous workers for the North
Atlantic region and Bay of Bengal. The influence of the wave
period 2 to 5 seconds on the rolling, pitching and heaving periods of
medium size vessels is also discussed.
