Foreign experience: lightning prptection of offshore oil and gas platforms

Foreign experience: lightning prptection of offshore oil and gas platforms

A common misbelief is that the offshore rigs and platforms "are grounded in the ocean" and therefore there no danger from lightning there. However, the truth is that the advanced electrical and electronic systems on offshore rigs may be particularly vulnerable for direct attacks, and secondary effects. How do oil and gas platforms protect themselves from lightning?
