Very easy: Instead of creating: 1 pipe, create: 3 pipes or 2 pipes encased in one another and leave empty space between the 3 or 2...And have sensors on it that way it will not spilled into the OCean, Specially in the Ocean....But they are SO CHEAP...And have in the biggest pipe have like a water faucets extensions protruding outward into the ocean that way when there is a spill in the smallest pipe it will leak to the second pipe (if you only had 2 pipes encased on each other) like how i was saying it will leak into the second pipe and they just come with big hoses attach it to the second bigger pipe faucet protrusion with a hose and suck up the oil....

or create a vacum in the space between the first and second pipe that way if there is a spill in the first pipe the vacum will empty out and the other end in the center on land....

Not a bad idea....

And in the lining of each pipe of all 2 pipes or all 3 pipes you put a: tires rubber lining, a thick tires rubber lining, which if there is a leak it will provide resistance and cause the pressure of the oil to gush even more at the other end on the center on land...

but again they are so <snip> cheap...
