The present invention relates to a method for the manufacturing of very high pressure vessels so that they survive high cycle fatigue loading. In particular, the method requires creating a residual tangential stress at a bore radius of a vessel such that the stress under load is more compressive than a maximum applied internal pressure. Furthermore, the method may require creating a residual stress a the inner radii of the supporting jackets such that the stress under load is compressive or zero.

[ I claim:] [1.] A method of manufacturing a pressure vessel that undergoes high cycle loading at very high pressures, the method comprising the steps of:providing one of a monobloc pressure vessel and a multilayered pressure vessel, said pressure vessel having an inside bore radius; andcreating a residual tangential stress across the provided vessel such that at the bore radius of the provided vessel, the tangential stress is more compressive than a maximum applied internal pressure.
