This project will be a professional bulk cargo terminal with a capacity of 300,000-ton in the future,adopting an open layout.However,the turning water area of this project is adjacent to the main channel(the main tidal channel),and the difficulty of ship maneuvering is high.The berthing and departure of 300,000-ton bulk carriers have a significant impact on the one-way channel.In order to ensure the safety and efficiency berthing and disembarking of large bulk carriers,through ship maneuvering simulation,the angle of connecting the water area to the turning circle is reasonably optimized,reducing the amount of reef blasting work.Scientific opinions are proposed on the overall layout plan,and guidance is provided throughout the process from tugboat configuration,berthing and departure restrictions,port entry and exit operation plans,port entry and exit navigation guarantee measures,and precautions.The results show that the ellipse with a design major axis of 847.5 m and a design minor axis of 678.0 m can meet the requirements of safe berthing and unberthing under the maximum flow velocity of level 6 strong winds and rising and falling tides.
