Embodiment 1
[0025] Embodiment 1, a ship of 2 tons class, ship width B=1.5m, midship radial circumference L=5m, the vertical component Hz=20A / m of local geomagnetic field, Hp=30A / m, realize overall Demagnetization, including the following steps:
[0026] (1) Steps for laying submarine cables: such as figure 1 , figure 2 , image 3 As shown, the left side submarine cable 3 and the right side submarine cable 2 are laid in parallel along the geomagnetic east-west direction in the seabed 7 of the water depth h=2B=3m, and the interval b=2B=3m between the left side and the right side submarine cables will be demagnetized Ship 1 is moored above the left and right submarine cables, the axis of the degaussed ship is parallel to the left and right submarine cables, and the projection of the demagnetized ship axis on the seabed is located between the left and right submarine cables;
[0027] (2) Steps of forming a loop: adopt the left side pulse power supply 5 and the right side pulse power suppl...
Embodiment 2
[0033] Embodiment 2, a 2000-ton ship, the ship width B=10m, the midship radial circumference L=50m, the vertical component Hz=30A / m of the local geomagnetic field, Hp=20A / m, realize overall demagnetization , including the following steps:
[0034] (1) Steps for laying submarine cables: such as figure 1 , figure 2 , image 3 As shown, the left side submarine cable 3 and the right side submarine cable 2 are laid in parallel along the geomagnetic east-west direction in the seabed 7 of water depth h=1B=10m, and the interval b=1B=10m between the left side and the right side submarine cables will be demagnetized Ship 1 is moored above the left and right submarine cables, the axis of the degaussed ship is parallel to the left and right submarine cables, and the projection of the demagnetized ship axis on the seabed is located between the left and right submarine cables;
[0035] (2) Steps of forming a loop: adopt the left side pulse power supply 5 and the right side pulse power s...
Embodiment 3
[0042] Embodiment 3, a ship of 30000 ton class, ship width B=30m, midship radial circumference L=100m, the vertical component Hz=20A / m of local geomagnetic field, Hp=30A / m, realize overall demagnetization , including the following steps:
[0043] (1) Steps for laying submarine cables: such as figure 1 , figure 2 , image 3 Shown, in the seabed 7 of water depth h=0.5B=15m parallel laying left side submarine cable 3 and right side submarine cable 2 along geomagnetic east-west direction, interval b=0.5B=15m between left side and right side submarine cable, will The degaussed ship 1 is moored above the left and right submarine cables, the axis of the degaussed ship is parallel to the left and right submarine cables, and the projection of the demagnetized ship axis on the seabed is located between the left and right submarine cables;
[0044] (2) Steps of forming a loop: adopt the left side pulse power supply 5 and the right side pulse power supply 4 to supply power to the left...
