Problems solved by technology

[0004] However, the above method does not consider the coupling between the atmosphere-ocean-wave in the actual use process, and ignores the tide level of the ship passing through the sea during the movement process with meteorological and hydrological changes, so there is a big problem with the calculation of the tidal water level. error and cannot provide theoretical guidance for actual shipping

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0028] In the description of the embodiments, unless otherwise clearly stipulated and limited, the terms "setting", "connecting" and the like should be interpreted in a broad sense. For example, it can be a fixed connection, a detachable connec...

Abstract

The invention discloses a large ship safe tide taking and port entering method based on dynamic conditions, and belongs to the technical field of water transportation traffic. The method comprises the following steps: building an atmosphere-ocean-sea wave coupled sea wave forecasting model; calculating environmental parameters of the large ship passing area by combining the topographic data of the sea area where the large ship enters the port by taking the tide; acquiring water level and three-dimensional flow field information based on a finite volume coast ocean model (FVCOM), and calculating a time point when a ship passes through a shallow point; establishing a simulation model by adopting simulation software, and simulating and calculating motion parameters of the large ship sailing in the corresponding dynamic environment; establishing a ship navigation database; and counting a suggested window period of safe tide-taking port entering of the large ship. According to the simulation model, the dynamic hydrological conditions of the sea area where the ship passes are considered, the calculation result is closer to the actual sea area environment, business collaboration of related production departments can be facilitated, and the ship entering efficiency is effectively improved on the premise that safe berthing and leaving of the ship are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water transportation, in particular to a method for safely entering a port by a large ship based on dynamic conditions. Background technique [0002] In port channel engineering, ships need to ride the tide to enter and leave the port, so the tide ride level is an important technical parameter in shipping and port design, and the water level and frequency of the tide ride level have important uses in shipping, port engineering or other coastal projects , to accurately predict the water level of the ship entering the port and the time for the ship to pass through the shallow point, which has important guiding significance for the safe navigation of the ship. [0003] The calculation of the existing tidal water level is generally carried out with reference to the "Code for Water Levels of Ports and Channels", which points out that "firstly determine the duration required for tidal riding, and on the process...
