The massive scale of the oil leak disater require a massive response. The failure of the toy cage and mud slingging into a mile deep ocean is now evident. The following illustration is a mamoth 40,000+ ton barge structure that matches the scale and magnitude of the disaster. It is easy to assemble using the readily available materials from sea shipping industry: It involves taking four barges and joining them together forming a square base, leaving about 200 feet square opening within. The next step is to create a massive steel wall using the shipping containers. The third step is to create a heavy duty steel pyramid over the steel walls. The fourth step is to attach a oil extraction connection. The fifth step is to gradually sink this 40,000 ton structure - the Big Barge gradually over the affected area of the leak. If the operation goes as planned, the oil can be extracted through the oil extraction connection. Because this structure is so heavy and sealed, the oil will have no means to escape it, even if the oil extraction operation is not fully successful. This is a fail-safe approach to contain a large affected area of the leak, as it is now suspected that the oil may be leaking from multiple sources near the mail leak. This operation does not require robotic precision that has proven unsuccessful one mile underwater. This sketch was submitted to BP official site and mailed to president Obama on May 28th, 2010.
