How to calculate sea state
WebHaving calculated or stored the lines defining the coast and the maritime borders between adjacent or opposite coastal states, the remaining boundary left to be calculated is the seaward outermost boundary of 12, 24 and 200 nautical miles, representing the hypothetical outer limit of the territorial seas, contiguous zones and EEZs respectively. WebRoll and pitch angles on the surface of a wave can be calculated from the wave profile slope and vessel heading as follows ( Fig 5 ): ψ = Atan (Tan ( α ).Cos ( μ )) φ = Atan (Tan ( α ).Sin ( μ )) Maximum Tilt: Unless you have a very strange vessel, e.g. wider than it is long, the greatest tilt will occur in Roll (not Pitch) for any given wave.

In physical oceanography, the significant wave height ( SWH, HTSGW [1] or Hs) is defined traditionally as the mean wave height ( trough to crest) of the highest third of the waves ( H1/3 ). Nowadays it is usually defined as four times the standard deviation of the surface elevation – or equivalently as four times the ...

The forecast contains details of wind direction and force, sea state, weather and visibility. Strong coastal winds (force 6 or more) are displayed for the first 24 hours of the inshore waters forecast.
Webc) On the basis of the above, determine the frequency of encountering different sea conditions, loading conditions, speeds, and headings. d) Determine the wave loads in each sea condition, loading condition, speed, and heading using first- or second-order strip theory. e) Use an extrapolation procedure to determine the distribution of the maximum Webz = distance from the baseline to the roll axis of rotation. The tangential roll acceleration at the height, h above the baseline is given by: Pitch motionand acceleration: {B500} …
WebWaves and swells depend on the wind, and sea state is characteristic of waves and swells. Understanding the sea state is important for various activities, such as sailing, fishing, offshore operations and boating. To measure sea conditions from calm to extremely severe, a numerical scale of Sea State 0 – 9 is used in the industry.
