Background

The oil and water pipeline system of the ship is widely distributed in each area of the ship as the 'blood vessel' of the ship. In the ship building stage, after the oil-water pipeline system is installed and reported, oil and water are injected to carry out system debugging and reporting. Due to the defects in the early design and the optimization and improvement requirements in the aspect of shipowners, the oil-water pipeline can be frequently modified; meanwhile, due to the fact that the quality of shipyard construction workers is uneven, the installation quality of pipelines is not too close, and the like, maintenance work such as replacement of flange gaskets or pipelines is conducted on the oil-water pipelines in the debugging stage. The oil and water in the pipeline need to be discharged completely under the above conditions.

At present, the method generally adopted for storing oil and water in the discharge pipeline of a shipyard is as follows: arrange a workman and twist specially an iron bucket or plastic drum and accept the profit of releasing, arrange another workman and loosen the pipeline flange, such mode of operation manual efficiency is low, considers simultaneously that the profit pipeline is general all complicated arranging on the cabin top, and the operation of on-the-spot workman twisting iron bucket eminence is neither safe, and the degree of difficulty is big again, still very easily causes the outer hourglass of profit, increases extra cleaning work.

The current trend of rapid shipbuilding is more and more obvious, the manpower cost control requirement is also more and more high, and the degree of stratification of the fine operation is also more and more thin, so the original extensive type oil release and storage water storage method can not meet the requirements of ship construction.
