Abstract：［Objectives］ In order to realize the rapid and convenient deperming of ships，a new design scheme for the coil system of an overrun deperming station is proposed.［Methods］Simulation models of the coil system are built，including the vertical compensation coil，horizontal compensation coil and vertical working coil，and the simulation analysis is performed by using software MagShip.［Results］The vertical compensation coil can produce an 80 A/m vertical compensation magnetic field with uniformity of about 95%；the horizontal compensation coil can produce a 40 A/m horizontal compensation magnetic field with uniformity of about 95% ；and the combination of both coils can compensate for the geomagnetic field in depermed ships. The vertical working coil can produce an alternating working magnetic field of more than 2 000 A/m，providing working energy for the deperming of ships. ［Conclusions］ The numerical simulation results show that the proposed deperming coil design scheme can not only compensate for the geomagnetic field but also produce an alternating magnetic field sufficient for realizing the deperming of a ship，which verifies the feasibility of the proposed coil system design. The results of this paper can provide useful theoretical guidance in the design of coil systems for overrun deperming stations. Key words：demagnetization；overrun deperming station；coil system

0引言

对船舶进行退磁最常用的技术措施是采用螺线管形式的多匝工作线圈，采用外部电源供电，被 部［1-5］。退磁船舶放置在线圈内 一个典型的例子是水下船舶退磁设施，即在退磁设施码头上安装框架式工作线圈，构成一个螺线管，其长度超过被退磁船舶。这种形式的工作线圈需要非常大的投
