Embodiment 1

[0067] Such as figure 1 As shown, a safe assessment method based on marine environment information, including the following steps:

[0068] Step 1. Develop a container ship plan route, the plan route consists of 2 voyage sections, the starting point of the route is P 0 (19.0 ° N, 136.2 ° E), route point (20.73 ° N, 140.1 ° E), the end point is P n (21.4 ° N, 144.5 ° E), the total distance of the route is 742.3 sea, starting time t 0 (Beijing time November 1, 2021, 8:00), arrived at time t n (Beijing time November 3, 2021), 6: 24).

[0069] Step 2, starting point P 0 (19.0 ° N, 136.2 ° e) is the starting point, planned speed limit 16 sessions, calculated according to the planned speed, saving a segment every 6 hours, a total of 8 segments. N = 8.

[0070] Segment D 1 Arrival point is P 1 And arrived time is T 1 (Beijing time November 1, 14: 00), 14:00), distance s 1 = 96 sea, the average speed is V 1 = 16.

[0071] Segment D 2 Arrival point is P 2 And arrived time is T 2 (Beijing t...

Abstract

The invention discloses an ocean course safety assessment method based on ocean environment information. The method comprises the following steps: step 1, making a planned course; step 2, dividing legs; step 3, making a circular area; step 4, acquiring data of the circular area; step 5, determining influence factor values of navigation safety of each leg Di, and performing leg safety coefficient Ai evaluation on each leg Di; 6, calculating the average value A of the navigation safety coefficients Ai of all the route segments Di of the route; step 7, calculating the airline safety coefficient A according to the airline safety coefficient average value A and the navigation safety coefficient Ai of each leg; and step 8, according to the airline safety factor A, evaluating the airline safety level. According to the method, after the route planning, the safety risk in the future navigation process can be evaluated, the route planning and the navigation starting time can be actively adjusted, the navigation safety is improved, and major marine accidents and economic losses are prevented.

Description

Technical field [0001] The present invention relates to a navigation area, in particular, involving a safe assessment method of ocean route based on marine environment information. Background technique [0002] In recent years, as maritime transportation technologies have become increasingly mature, ocean transportation has become one of the great economic lifelings. Ocean navigation is due to large geographic span, long time cycle, and the safety of route is affected by the composite effects. The route safety assessment is a technical means for sailing safety risk assessment before the ship sailing. The safety risks of the route are the comprehensive considerations of sailing safety risks at each stage of the route. [0003] Sailing safety assessment elements at a time of ships in addition to the ship's own ship age, tonnage, sailing speed, and focus on marine environment information such as wind, waves, visibility. Great winds are an important factor in the overtime accidents s...
