Aircraft operations in Antarctica and resupply of inland stations require the transport of more than 3,000,000 gallons of bulk fuel annually from storage at McMurdo Station to Williams Field on the Ross Ice Shelf. This has been accomplished by pumping JP-4 aircraft fuel through a temporary surface hoseline crossing annual sea ice and by trucking of lower use fuels. A study of permanent fuel-line systems crossing deep snow indicates that an elevated hoseline supported from a steel messenger cable on simple towers is feasible for reducing the man-effort required in placement, recovery and maintenance of a surface-laid system. The elevated system, which can accommodate differential movement in the ice shelf and permits reelevating the line as snow accumulates, requires no new technology but does require field evaluation to determine tower foundation and anchor requirements in deep snow. Based on this study, it is recommended that an experimental section of elevated fuel line be constructed to gain needed data for design and construction of an operational fuel-transport system.
