The article presents method of calculating the maximum external hydrostatic pressure for the construction of an underwater scooter. The calculations were performed using analytical formulas and FEM analysis in the Solid Works Simulation program. An experimental verification of the strength of the scooter structure in the pressure chamber was carried out. It made possible an initial verification of analytical formulas and the MES Solid Works Simulation software used in the issue.
