Abstract: A Patch for Ruptured Fluid Tanks consisting of a container having an opening a peripheral edge. A rupture in a fluid tank is enclosed within the peripheral edge of the opening. A fluid filled tubular seal is provided along the peripheral edge of the opening. The tubular seal compresses to bring the opening of the container enclosing the rupture into sealing engagement with the fluid tank. A fluid bypass passage is provided through the container. Fluids escaping through the rupture flow through the bypass while the container is being placed over the rupture. The container is secured by cables to a fluid tank. The bypass passage is remotely closed to contain fluids escaping through the rupture within the container once the container has been secured to the fluid tank.
