Abstract： Attitude adjustment is a key link in the installation process of underwater facilities in deep water. To solve this problem, an omnidirectional spirit level for deep water was developed. The sealing principle of the spirit level and the principle of deep-water pressure resistance are analyzed, and the threaded connection strength is checked. The mechanical simulation verifies that the spirit level can withstand the pressure of 2 000 m water depth, and the water pressure test is carried out for 30 min in a 20 MPa hyperbaric chamber. After the experiment is completed, the appearance of the spirit level is intact and there is no leakage. The experiment results show that the deep-water omnidirectional spirit level can be used in the deep sea within 2 000 m.
Key words： deep water omnidirectional spirit level; attitude adjustment; pressure test; underwater pressure
