Studying On The Design Of Loading And Unloading Heavy And Lengthy Cargo Scheme By Vessel

With the development of economy and the progress of era, the division of labor in social is becoming more and more clear and refined. Project equipment is bigger and bigger, so the requirement of transportation is becoming higher and higher, carriage of goods by sea is also present professional, science, technology and diversification. Large project equipment like a lock, yacht, nuclear generator, piers, etc. The size and weight is increasing gradually. The traditional general cargo vessel has couldn’t keep up with the pace of the era and has not adapt to this kind of goods too. Needing to use the modern professional heavy cargo transportation ships instead. Most port crane handling ability is limited, naturally can’t meet the above requirements on the loading and unloading of the goods, so cargo vessel equipped with heavy lift crane is a kind of trend.When vessel loading and unloading heavy cargo, the vessel’s parameters like draught, trim, heeling angle, stability and so on changing all the time. The heavier of the goods, the greater effect on the ship, the more the ship parameters change. Because the value of the goods and the vessel is so high, ensuring the safety of cargo loading and unloading and transportation is very important. The traditional manual calculation processing complex, the ballast water is needed in the process of operation, so the seaman is very busy when operation and unable to forecast the unknown risks, then easy to cause damage to ships and cargo, thus result in huge economic and property loss. To reduce the workload and ensure the safety of heavy and lengthy cargo transportation, the shipping company and the owner need to loading and unloading and transportation plan ahead. To ensure the safety of the vessel during loading and unloading heavy and lengthy cargo operation, it is the urgent need to put computer technology into use to improve quality of loading and unloading and transportation heavy and lengthy cargo.In this paper, first of all, summarizing the concept, classification and characteristics of the heavy and lengthy goods and heavy lift vessel。Researching and discussing to make plan of loading and unloading heavy and lengthy cargo. Secondly, emphasis to derivate transformational formula of heavy lift vessel cooperate to lift heavy and lengthy cargo. Then, analyzing the force the cargo beard when it hung on the double cranes, the lifting process is decomposed into hanging two cargo at the same time and inducing the coordinate relationship of the horizontal angles. Moreover, Again, based on VB 6.0 and AutoCAD drawing software, designing the software to simulate the procedure of the cranes load and unload heavy and lengthy cargo and making the calculation software to make it simplified. Finally, Imagine the full-automatic, three-dimensional, dynamic loading instrument of heavy-lift vessel in the future.
