Abstract:

A series of interrelated seafloor engineering experiments was conducted in 600 feet of water on the seafloor 7 miles south of Santa Barbara, California, between July 1969 and August 1972. The experiments involved the evaluation of equipment and techniques by the Civil Engineering Laboratory CEL at Port Hueneme, California. The Navy Seafloor Construction Experiment SEACON demonstrated a capability to construct operating facilities at the bottom of the ocean and pointed up deficient areas in the state of the art. The focal point of the SEACON I experiments was the construction and evaluation of an unmanned, one-atmosphere concrete structure placed at the 600-foot site. Experimental evaluations of hardware and techniques for site selection and investigation, seafloor construction, and structural and electrical elements were coordinated with the year-long seafloor testing of the concrete structure. The construction site was investigated using tools operated from towed vehicles and manned submersibles as well as surface vessels. In-situ tests to determine short- and long-term settlement behavior of model footings were performed.
