This report discusses the technology required to develop unmanned free-swimming submersibles to be 

 used for inspecting undersea pipelines and structures. Of particular concern is the use of solid-state electronics 

 and microprocessor technology. The philosophies concerning performance criteria, design flexibility, man/ 

 machine interface, and cost are discussed, and the vehicle's performance in these areas is evaluated.
