This dataset collects 22 types of meteorological data under 6 categories, wind and wave forecasts, and geographic information of shipbuilding and ship-repair enterprises, aiming to explore the impacts of various meteorological factors on the ship repair and construction processes of vessels during docking and undocking operations. We developed a meteorological risk forecasting model for docking and undocking operations, built a professional meteorological service platform, and launched digital service products including real-time meteorological monitoring over-threshold alerts, hourly-to-daily dynamic meteorological risk early warnings, impact prompts and targeted response measures. This system realizes the closed-loop management of the entire process of meteorological risk for docking and undocking operations, from observation, forecasting and early warning to service provision and emergency disposal, effectively improving the meteorological risk prevention capabilities and safe production efficiency of enterprises. Based on real-time updated in-situ observation or forecast data, the corresponding impact level of meteorological factors for docking and undocking operations is derived, where the highest level among the meteorological risk levels of all factors is selected via the maximum function method. Assuming the meteorological risk level of docking and undocking operations is Y5, the specific calculation formula is as follows:
Y5 = max(Yw, Yr, Yt, Yv, Ym)
Where:
Yw: Meteorological risk level corresponding to wind force. Level Ⅰ (high risk) when wind force > 8; Level Ⅱ (medium risk) when 6 < wind force ≤ 8; Level Ⅲ (low risk) when wind force ≤ 6.
Yr: Meteorological risk level corresponding to precipitation. Level Ⅰ (high risk) when rainfall ≥ 20.0 mm; Level Ⅱ (medium risk) when 10.0 mm ≤ rainfall < 20.0 mm; Level Ⅲ (low risk) when rainfall < 10.0 mm.
Yt: Meteorological risk level corresponding to air temperature. Level Ⅰ (high risk) when air temperature < 0.0℃ or ≥ 37.0℃; Level Ⅱ (medium risk) when 0.0℃ ≤ air temperature ≤ 3.0℃ or 35.0℃ ≤ air temperature < 37.0℃; Level Ⅲ (low risk) when 3.0℃ < air temperature < 35.0℃.
Yv: Meteorological risk level corresponding to visibility. Level Ⅰ (high risk) when visibility ≤ 1000 m; Level Ⅱ (medium risk) when 1000 m < visibility ≤ 2000 m; Level Ⅲ (low risk) when visibility > 2000 m.
Ym: Meteorological risk level corresponding to convective weather. Level Ⅰ (high risk) when lightning occurs within 5 km; Level Ⅲ (low risk) when no lightning occurs within 5 km.
