However, for a 300,000-ton VLCC (generally including 17 cargo oil tanks and 12 ballast tanks, a total of 29 tanks), and its cabins are relatively large, the required time for each ballast tank to be filled with ballast water It takes a long time, and the strength test of a VLCC is generally accompanied by the entire sea trial process, and the requirements for the stowage procedure of the strength test are higher

A strength testing method for a very large crude carrier. The very large crude carrier comprises an after peak, a forepeak, and several compartments located between the after peak and the forepeak, and the several compartments are arranged in sequence in the length direction and the width direction of the very large crude carrier; the method comprises: partially loading the after peak or the fore peak with fresh water, and loading ballast water in the several compartments alternately in sequence from boards at both sides to the center in the width direction of the very large crude carrier, such that the inside and / or the outside of a side wall of each compartment is in contact with the ballast water to implement a strength test. By making a rational loading order, the method can rapidly complete a strength test for the very large crude carrier during a trial voyage without the need of loading all the compartments with ballast water for the strength test, shortening trial voyage time, reducing trial voyage costs.
Description
technical field [0001] The invention relates to ship strength test technology, in particular to a strength test method for super-large oil tankers. Background technique [0002] At present, according to the relevant requirements of the classification society rules that the ship is classified into, the strength test of the cargo hold / ballast tank is required before the delivery of the ship to verify the rigidity and strength of the cargo hold structure, and the tightness of the perimeter of the cabin needs to be checked at the same time. [0003] When a ship undergoes a strength test, it generally needs to be carried out during the sea trial of the ship. For general oil tankers (with a deadweight of 150,000 tons and below), due to the small number of cabins (generally 5 pairs of ballast tanks and 6 pairs of cargo oil tanks, a total of 22 tanks), when carrying out the stowage of the strength test, its Fewer stowage conditions are required (ie fewer combinations of compartment...
