Sea water is highly conductive, with potential close to ground, so the high potential cable cannot be allowed to touch it. So the cable has to be well insulated

Sea water is highly conductive, with potential close to ground, so the high potential cable cannot be allowed to touch it. So the cable has to be well insulated from the water. Discharge can happen in this insulation, that's why it has to be thick enough.
