No, Piper Alpha was not caused by that. But as I keep pointing out, and as you keep ignoring, the Arctic Sunrise is a single-engine, single screw vessel that approached well within the Safety Exclusion Zone of an offshore structure without the protection of either a tug or guardboat. It continued to remain within the Zone despite repeated requests to move away.

Whatever your feelings about arctic exploration, this act in itself is extremely reckless and dangerous and would have resulted in the arrest of the vessel in virtually any jurisdiction in the world. An engine or drive-train failure COULD have resulted in a collision with the platform and widespread destruction with injuries and possible deaths.

These Safety Exclusion Zones are there for a reason, implicitly bound up with safety and environmental protection and for an organisation that purports to be concerned about the environment to do this I find almost incomprehensible.
