Formula, assumptions, limits

\text{Permit} = (H_{sig} \leq H_{limit}) \land (V_{wind} \leq V_{limit})

W2W gangway transfer permitted when both significant wave height and wind speed are below manufacturer-specified operational limits. Typical limits: 2.5 to 3 m Hsig, 25 to 35 kn wind. The ship must also meet DP-2 stationkeeping criteria. The IP Code Chapter 13 (Personnel transfer) sets the framework; specific limits depend on gangway model, ship type, and operator policy.
