Beam force
Input(s)
H: Significant Wave Height ( \(\mathrm{ft}\) )
B: Vessel Beam Length (ft)
L: Vessel Length \((\mathrm{ft})\)
A: Wave Period (s)
D: Vessel Draft (ft)
Output(s)
\(F_{b a}\): Beam Force When a Is Greater Than \(0.642 *(\mathrm{~b}+2 * \mathrm{~d}) 0.5\left(f t^{5} / \mathrm{s}\right)\)
\(F_{b b}\): Beam Force When a Is Lower Than \(0.642 *(\mathrm{~b}+2 * \mathrm{~d}) 0.5\left(f t^{5} / \mathrm{s}\right)\)
Formula(s)
\[
\begin{gathered}
F_{b a}=\frac{2.1 *\left(H^{2}\right) *\left(B^{2}\right) * L}{A^{4}} \\
F_{b b}=\frac{2.1 *\left(H^{2}\right) *\left(B^{2}\right) * L}{\left(1.28 *\left((B+2 * D)^{0.5}\right)-A\right)^{4}}
\end{gathered}
\]
