Proposal for a shipborne auv refuel system
Proposal for a shipborne auv refuel system
Autonomous Underwater Vehicles (AUVs) are limited by the quantum of energy they can carry. Contemporary operational strategy is either to remove and replace the fuel source, or to refuel on-deck. Both strategies require the vehicle to surface, be recovered and be relaunched. This proposal obviates the time inefficiency by a novel arrangement of a shipborne electromechanical cable combined with a deepwater vehicle dock, similar to the concept of aerial refuel. The paper describes the almagamation of an algorithm due to Pode, Eames, Berteaux, and Knutson. The purpose here is to solve the differential cable equation in order to estimate loads and costs. A comparison between published data and the present algorithm satisfies reliability considerations.
The results of the present algorithm are extended to answer such questions as 1) how long a cable is needed under specified conditions?, and 2) what are the loads and moments felt at the ship? At least three electromechanical (EM) cables are specified. One steel EM cable and two kevlar EM cables are compared in terms of performance and cost. The frequency analysis of Milburn is repeated for the three cables. Survey-class AUVs are described and their salient parameters reviewed. Cable scopes required at increments of depth are tabulated for the kevlar cable. Detailed design can proceed based on this preliminary proposal.

Abstract
Autonomous Underwater Vehicles (AUVs) are limited by the quantum of energy they can carry. Contemporary operational strategy is either to remove and replace the fuel source, or to refuel on-deck. Both strategies require the vehicle to surface, be recovered and be relaunched. This proposal obviates the time inefficiency by a novel arrangement of a shipborne electromechanical cable combined with a deepwater vehicle dock, similar to the concept of aerial refuel. The paper describes the almagamation of an algorithm due to Pode, Eames, Berteaux, and Knutson. The purpose here is to solve the differential cable equation in order to estimate loads and costs. A comparison between published data and the present algorithm satisfies reliability considerations.
The results of the present algorithm are extended to answer such questions as 1) how long a cable is needed under specified conditions?, and 2) what are the loads and moments felt at the ship? At least three electromechanical (EM) cables are specified. One steel EM cable and two kevlar EM cables are compared in terms of performance and cost. The frequency analysis of Milburn is repeated for the three cables. Survey-class AUVs are described and their salient parameters reviewed. Cable scopes required at increments of depth are tabulated for the kevlar cable. Detailed design can proceed based on this preliminary proposal.
