Components of the Navy's SeaLab III project was the development of underwater construction methods. This film presents the design and operations of the Buoyant Transport Vehicle, (BTV), a remotely operated underwater forklift vehicle developed by the Hawaii laboratory of the Naval Undersea Research and Development Center. BTV field testing including running an underwater course and payload handling was done off Anacapa Island by the U.S. Naval Civil Engineering Laboratory, Port Hueneme, California. Next, the BTV was used in assembling the DIVERCON module in the DIVERCON BTV Exercise, saving one third of the underwater construction time over previous construction methods. Finally, the BTV was transferred to the Naval Undersea Center in San Diego for use as a range support vehicle.
