摘要：【課題】船舶の永久磁場の経時変化を考慮して、運用中において船舶の外部磁場を精度良く低減化することができる、船舶の磁場低減方法を得る。【解決手段】前回の船舶運用期間である運用期間P1における船舶の永久磁場L1の経時変化を一次関数的な変化として捉え、同様な永久磁場L1の経時変化が運用期間P2においても生じると推定する。上記推定に従い、運用期間P2における運用中時刻t2xを現時刻とし、運用中時刻t2xの消磁完了時刻t21からの時間を現在運用期間Δtとすると、前回残留磁場M0(=F11)、前回運用期間T(=P1)、前回運用後磁場PM(=F20)、今回残留磁場M1(=F21)を用いた1次関数によって、運用中時刻t2xの現在推定磁場MCを導出することができる。【選択図】図1

摘要： PROBLEM TO BE SOLVED: To eliminate the necessity for the calculation of a hull magnetism for each section of a vessel having a complicated shape/structure, to shorten the period of time for a demagnetization process by simplifying the calculation for the hull magnet, and to increase the demagnetization performance. SOLUTION: A hull magnetism simulation form 28 is defined by estimating a hull magnetic behavior from data indicating the shape/structure of the vessel 4. The hull magnetism is calculated from the defined hull magnetism simulation form. A processing device which demagnetizes in such a manner that a magnetic variation occurring on the outside of the hull may be reduced by using a set value for a demagnetization element obtained from the hull magnetism is provided.

摘要： PROBLEM TO BE SOLVED: To provide a current adjustment method of a demagnetization coil for a vessel capable of increasing a reduction ratio of a far magnetic field as compared with a conventional one and capable of easily performing setting of an energization amount at the vessel. SOLUTION: An energization amount ATO of each M coil is made to the same common value α and a variation degree ΔAt of the energization amount (ST1, ST2) and the energization amount of each M coil is made to α+ΔAT (ST3). Subsequently, a mistake fit degree Mrn of a coil effect degree by the energization amount at this time and a hull magnetic at demagnetization is calculated (ST4). The mistake fit Mrn at this time and the former mistake fit degree Mra are compared with each other (ST5). When Mrn at this time is small, the energization amount of each M coil is increased by ΔAT and new Mrn with the hull magnetic at demagnetization is determined. The processing is repeated until the mistake fit degree Mrn at this time exceeds the former value. When the mistake fit degree Mrn at this time exceeds the former value, ATn at this time is made to an initial value ATf (ST7) and thereafter, it is transferred to individual adjustment of each M coil.

摘要： PROBLEM TO BE SOLVED: To enable sure detection of the changing value only of an eddy current magnetic field accompanied by the fluctuations of a hollow structure body which is not caused by the change in the geomagnetism. SOLUTION: Geomagnetism near a hollow structure body 24 is detected by a geomagnetism detector 26, a mean of a changing value of the detected value is calculated by a mean detecting circuit 28 and the deviation between the detected magnetic signal and the mean value is calculated by a deviation detecting and amplifying circuit 30, based upon the detected value as a standard value. Additionally, the deviation value is differentiated by a differentiating circuit 36 to find a signal component which becomes reverse polarity with respect to an eddy current magnetic field, the signal is transferred to an electric current signal by current output transformers 16 and 18 to make an electric current flow through demagnetizing coils 20 and 22, and the eddy current magnetic field generated by the hollow construction body 24 is demagnetized.
