Solution that we could use to defend ourselves while also protecting attacker from injury.
Yesterday, we posted a theory for putting an end to this disaster in the Gulf: use the force of the oil against itself. Today, we present our concept based on this theory to put an end to the most devastating environmental disaster of our history.
The principle of this concept is based on a ball check valve that contains strategically engineered ram-fed passages inside the walls of the device for bypassing oil pressure. The primary cylinder of this device is equipped with O-rings to serve as the sealing mechanism at the top and to hold the ball in place on the bottom.
The bladder-shaped passages inside the walls channel the oil out of the device while alleviating the pressure to ensure precision and ease of installation. The ram-fed passages increase the velocity of the oil flow just prior to exiting the top vents creating a suction force which aids the release of pressure. In between each passage are additional vents to enable and manipulate the flow of oil through the device. These vents help control the oil pressure pushing against the primary cylinder. Once the device is in place, the vents can be closed, activating the check valve. Therefore, as we presented in our theory, we use the force of the oil spill to cap itself.
The diagram to the right displays a cross-section view of our concept while it is stationary. The red dots represent O-rings that will seal the device to the leaking pipe and the device itself. The black elements indicate butterfly valves as inlet and exit ports of the oil flow. Portions of these vents are equipped with bladder-shaped passages. As with most ball check valves, there is a portion near the top where the body comes in so that the ball can seal against the O-ring and not allow fluid to pass. This body shape for a ball check valve is common.
How it will work
A very simplified depiction of how this concept will work is shown in figures above and below. The purple arrows represent the flow of oil through the bladder-shaped passages.
In the diagram above, the device channels the oil vigorously through its ten openings. The oil will flow through the bladder-shaped passages, vents, primary cylinder of the device and around the ball. Each of these openings in the device cause some of the oil pressure to be bypassed so that the device can be attached to the leaking pipe without as much force.
The pressure inside the primary cylinder will increase, raising the ball as shown below (left). When the vents and passages are closed via the butterfly valves, the oil is no longer bypassing through the openings of the body. This causes the oil pressure to direct its energy and push the ball up towards the O-ring, and consequently seal the device as shown below (right).
The figure below and to the left displays a cross-section view of the device with the bladder-shaped passages inside (left) and a front view of the passages.
The passages expand at the exit point. This mechanism creates an increase in velocity, and a suction force that helps the oil escape efficiently. In turn, it provides ease of installation. The bladder’s wall thickness also increases at the exit point to further prevent rupture and over pressurization.
The diagram to the right displays a top view (up) of the device and a side view of the opening and closing mechanism (bottom) for each hole. From the top view, there are 10 openings, 5 of which contain connected passages and 5 of which are vents. The vents allow for the oil to pass through the device for easy installation. The two images show the closed (left) and open (right) positions. Each of these openings contain a butterfly valve which can be triggered to close once the device is attached to the leaking pipe.
Below is a list of requirements that must be considered in developing this concept:
- The material and weight of the ball must be calculated based on the pressure bypassed through the openings
- The sequence of the valve operation is critical to manage the pressure to activate the check valve.
- A retaining spring could be explored for connecting the ball to properly manage the check valve function.
- All material properties used in this device must be properly engineered for the ocean floor conditions and petro-chemical application.
This is one concept we have developed from our theory post. We invite everyone’s participation to share and contribute their knowledge and experience to develop this or another concept so that we can have a truly effective action for disasters such as this.
