PRESSURE TESTING FACILITIES

Following is a list of pressure testing facilities in the greater San Diego area.

Pressure testing is used to simulate underwater conditions for evaluating instrumentation, cables, connectors, and other subsea equipment. In general these hydrostatic chambers use fresh water as the pressurizing fluid. The pressurization rate can simulate either accelerated or real time transits and ocean bottom periods. Some can also control the water to a specified temperature. Electrical connections and feed-throughs and other specialized adaptations like fiberoptic or hydraulics, allow for operating equipment or monitoring sensors while at pressure. The availability of these features are noted where known.

While the information below is believed to be accurate at the time of this writing (December, 2000), we cannot warranty its accuracy. Please contact the individual facility to verify their capabilities.
