Abstract

The invention discloses a method of preventing a ship from sinking and grounding when entering and leaving a special restricted waterway, and belongs to the technical field of ship transportation. The method of preventing the ship from sinking and grounding when entering and leaving the special restricted waterway specifically comprises the steps of S1, data collection; S2, data arrangement and classification; S3, data processing, wherein calculation is conducted according to collected data and data obtained by inquiring charts, and the calculation content comprises an average sinking quantity delta H1, an actual underkeel clearance delta H3 and a ship wave amplitude delta H2. According to the method of preventing the ship from sinking and grounding when entering and leaving the special restricted waterway, calculation of the actual underkeel clearance delta H3 and the ship wave amplitude delta H2 is added to an existing method of preventing the ship from sinking and grounding when entering and leaving the special restricted waterway, the calculation of the actual underkeel clearance delta H3 and the ship wave amplitude delta H2 is taken into consideration of factors of ship operation condition when it is judged that whether sinking and grounding will occur on the ship or not when the ship enters and leaves the special restricted waterway, and in this way, the effect of preventing the ship from sinking and grounding when the ship enters and leaves the special restricted waterway can be achieved better.

Description

technical field [0001] The invention relates to the technical field of ship transportation, in particular to a method for preventing a ship from sinking and bottoming out when entering and leaving a special restricted waterway. Background technique [0002] When a ship enters or exits a special restricted waterway, it belongs to shallow water navigation. As a navigation state of restricted water navigation, shallow water navigation has its own unique navigation rules, such as reduced ship speed, reduced rudderability, reduced gyration, sinking of the hull and The increase of the trim change, etc., and when navigating in shallow waters, due to insufficient consideration of the sinking of the hull, the ship drags the bottom, hits the rock, runs aground, and loses control, etc., which is also a common type of average accident. Therefore, how to correctly understand And to determine the sinking of the ship's hull and the sufficient water depth when sailing in shallow waters, and...
