Unfortunately, protection is about earthing - not about oceans.
Simple surge protection ( not talking ligtning) can also be simply
clamping the voltage line to neutral with no ground involvement.
Varistors do this quite effectively. A more accurate description of
the power anomoly we are talking about is a "transient" - and the
devices are often referred to as "transorbs"
They (the anomolies) can also be referred to a "pulses".
MOV Transorbs can be connected line to line, line to neutral, or line
to ground.
