A hydrocarbon tank system environment corrosion inhibitor includes use of inert gas, preferably Nitrogen, to blanket ullage and interstice through the tank system. Blanket gas is provided via controller into coupling to access ullage. Blanket gas is provided upon fueling events to stabilize the pressure in the system and prevent entry of atmospheric air and water (vapor). Blanket gas may be continuously run into the ullage and/or other spaces in tank system. A controlled system allows for monitoring of pressures in the tank, and thereby identifies pressure events and even leaks in system due to unusual events, or general loss of pressure.

Protective covers (e.g., liners) for use in protecting aircraft cargo hold floors from potentially harmful or dangerous fluids and other substances, and from physical damage, are described herein. In some embodiments, the cargo pit liners described herein can include a plurality of raised portions and adjacent recesses that provide a protective barrier between cargo and a floor of the cargo pit. The raised portions can facilitate movement of cargo and improve impact resistance, and the recesses can collect and retain potentially detrimental fluids.

Systems, methods and apparatus for launching and recovering a vehicle via a side manway of a tank are provided. A launcher is coupled to a vertical side of the tank via a manway adapter. The launcher includes a first side having a lid and a second side configured to couple with the manway adapter. The lid is removed from the first side of the launcher. An autonomous vehicle is loaded into the launcher via the first side of the launcher. The lid is placed on the first side of the launcher. The launcher can be pressurized with the autonomous vehicle inside the launcher. The manway adapter is opened at the second side of the launcher to release the flammable fluid into the launcher. Subsequent to opening the manway adapter, the autonomous vehicle launches from the launcher into the tank to perform a tank inspection process.
