Design of an underwater vertical glider for subsea equipment delivery

Delivery of subsea equipment and sensors is generally accomplished with unguided sinking platforms or powered autonomous underwater vehicles (AUVs). An alternative would be to augment existing platforms with navigation and guidance capability, enabling them to actively guide themselves to their destination, with minimal added complexity and power consumption. This defines a new class of AUV having 110 propulsion, which we call the Vertical Glider. This thesis investigates the challenges posed by this deployment concept, and describes in detail a prototype vertical glider that was built for initial tests. We explore through computer simulation the specific roles of various operating parameters, such as control gain, measurement noise, and process noise, on the overall vehicle performance. The prototype vehicle has been successfully pool-tested, and serves as a baseline platform for open water operations and multi-vehicle deployments.
