Encircle the leak by using hundreds of US Naval ships, battleships, aircraft carriers, destroyers and subs plus hundreds of oil tankers to maintain a 10K perimeter with a 10 layer tyvex and steel cable shroud anchored by the largest circular anchor ring ever assembled (10k+ tonnes) then begin harvesting the contained area into the tankers until the leak has drained itself out so the pipe can be replaced and a cap can be placed... next challenge: capture all the methane being released.
