Ship loading performance optimization system

Abstract

The invention discloses a ship professional loading calculating system which helps a navigator to account ship floatation condition, stability and strength, and optimizes running longitudinal trim of a ship, and simulates a ship loading process. The system is a ship loading instrument The system comprises four sub-calculation systems of ship performance calculation, ship performance check, ship longitudinal trim optimization, and ship loading process real-time simulation. Through selecting different sub-calculation systems and cooperation among the sub-calculation systems, and inputting corresponding ship parameters, a basic data condition of safe and economical navigation of the ship can be obtained. The invention also provides a method for ship floating state adjustment, stability and strength accounting, longitudinal trim optimization, and ship loading process real-time simulation by using the above software. The system can ensure ship loading and navigation safety, and simplifies ship loading operation and saves energy, so as to improve security and economical efficiency of shipping, and reduce burden of navigators to a large extent.

Description

technical field [0001] The invention relates to the field of ship operation management, in particular to a ship loading performance optimization system. Background technique [0002] The design and construction of ships has a long history. Due to its strong transportation capacity and good economic performance, it developed rapidly in the 1970s and 1980s, especially the rapid development of large bulk carriers and container ships. Due to the increasing demand for cargo transportation and the continuous improvement of shipbuilding technology, the development of ships tends to be standardized and large-scale, from small tonnage in the early 1960s to 10,000 tons in the 1960s and 1970s, and then to hundreds of thousands of tons today, and there will continue to increase big trend. [0003] However, ship accidents at sea are always accompanied by the development of the fleet, and ensuring the safety of ship transportation is an important task of ship transportation. According t...

Problems solved by technology

According to the investigation and analysis of a large number of ship accidents, unreasonable stowage will cause serious arching or sagging of the ship, especially under the action of swells, strong shear force, bending moment, and twisting moment will be generated, resulting in de-welding of ribs, Critical phenomena such as cracking of steel plates lead to damage or even breakage of the hull structure when the ship is loaded with heavy cargo or in compartments under harsh weather conditions
