The high pressure tank is used to test the capability of equipment operating in deep-water conditions so as to shorten the period of time for research and development. It measures the test system of sealing performance, strength, leakage, stability, ultimate load capacity and fatigue performance.

The tank is with an inner diameter of 3 meters and an effective height of 4 meters, has the maximum operation pressure of 60 MPa. It equipped with pressure vessel, pressure relief system, control system and measuring system.
