VLCC压载舱泥沙淤积成因及对策

Cause and Countermeasure of Sediment Deposition in VLCC Ballast Tank

行驶于海洋中的VLCC油轮进入多沙水域港口、卸油置换压载舱水配重时,带来压载舱内泥沙的淤积。文章以舟山水域为背景,以油轮边压载水舱作为研究对象,分析油轮边舱泥沙运动规律及泥沙淤积的成因,提出采用气动冲沙的方法处理压载舱泥沙,为行驶于海洋中的大型油轮和船舶压载水舱泥沙提供合理的清淤管理。

When the VLCC tanker driving in the ocean enters the port of the sandy waters and discharges the water weight of the ballast tank,the silt in the ballast tank is deposited.Taking Zhoushan coastal waters as the background and the ballast water as the research object,the sediment movement law and the cause of sediment deposition are analyzed.It provides a new method which uses pneumatic sand washing to reduce the ballast sediment for large oil tankers and other vehicles in the ocean.
