Crosses one or more earthquake faults, yes?
“Crosses one or more earthquake faults, yes?” Several and tectonic spreading center. As such this is not a problem as it is a floating suspension pipeline at depth but not on the ocean floor.
Considering the animosity between Greece and Turkey and their war over Cypress years ago what they really need to worry about is a Greek anchor behind a freighter. You could destroy it for just a few thousands of dollars.
I think that’s why they went with a tethered, level pipeline, it’ll ride out the shock wave.
