Floating roof tank for a volatile liquid have an outer roof and an internal floating roof with a primary seal with a support such that when the tank is empty, the floating roof will rest on the support whether the tank is in a vertical or horizontal position. The support enables the tank to be transported in a horizontal position without damage to the seal. The floating roof tank with support can be configured as a conical tank, flat bottom tank or slant bottom tank. The floating roof tank can also include a cleaning system and a flush mounted manway cover.

A secondary seal system for a storage tank having a floating roof includes a seal compression plate attached to and extending upwards at an oblique angle from the floating roof, extending around the circumference of the floating roof; a seal element attached to the compression plate for sealing between the compression plate and an inner surface of the storage tank; a plurality of anti-rollover plates attached to and extending upwards from the seal compression plate; and a plurality of anti-rollover braces attached to a major surface of the seal compression plate.

Apparatus and methods for measuring the deformation in a floating-roof seal assembly. A fiber optic cable is attached along its length to the floating-roof seal assembly such that the fiber optic cable is deformed when the floating-roof seal assembly is deformed. Deformation of the fiber optic cable and the seal assembly can be determined based on how the light interacts with the fiber optic cable. This helps allow tanks with a floating roof to be monitored.

Various embodiments generally relate to robotics and more specifically to tank seal inspections. In some embodiments, the robotic inspection device comprising a power supply, a body, a drive system, a camera, a navigational system, and/or one or more sensors. The drive system may include one or more surface engaging drivers to propel the robotic inspection device along a surface of a tank. The camera can be housed within the body to capture images and/or video of a seal. The navigational system can compute a route (or receive commands that route) and send commands to the drive system to navigate the robotic inspection device along the surface of the tank allowing the camera to capture the images or video of the seal. Some embodiments may use an artificial intelligence or machine learning engine to review the images or video of the seal and identify potential problems.

Apparatus and methods for monitoring the status of a floating roof. The floating-roof tank assembly has: an impermeable roof section, and a floating-roof seal configured to span between the impermeable roof section and components of a container. One or more deformable floats are attached to the roof section to provide buoyancy so that the roof floats on top of the liquid contained in the container. To monitor the status of the floating roof tank, it is provided with a fiber optic sensor array comprising one or more fiber optic sensors. A light source configured to transmit light to the fiber optic sensors and a receiver configured to detect light from each fiber optic cable after it has interacted with the fiber optic cable. Based on the received light, a controller configured to process the light received by the receiver to determine the status of the floating roof tank.
