This paper presents a new low-cost autonomous underwater vehicle (AUV) for inspection of water-filled tunnels. Deployment in flowing water tunnels and later retrieval at the tunnel exit produces a two-dimensional height vs. time plot of the tunnel, which can be compared to tunnel schematics. The resultant contour data is useful for maintenance planning and tunnel assessment in terms of internal clogging. This paper presents a proof-of-concept for traversing water filled tunnels by using water flow and variable buoyancy. Empirical data is collected in a scaled down version of one specific water supply tunnel in Norway.

Thrust Vectoring

In this paper, we present the design and proof of concept of a streamlined, low-cost, and smooth-hulled underwater vehicle (MASUV-1). MASUV-1 utilizes an ad-hoc designed multi-directional thrust-vectoring system for steering and an entirely enclosed propulsion system, allowing for safe operation in the vicinity of marine mammals. Tests of the vehicle in a still water environment show high maneuverability at speeds comparable with similar torpedo-type class underwater vehicles.
