Abstract: The present invention relates to a method for the manufacturing of very high pressure vessels (10) so that they survive high cycle fatigue loading. In particular, the method requires creating a residual tangential stress at a bore radius (a) of a vessel (10) such that the stress under load is more compressive than a maximum applied internal pressure (pi). Furthermore, the method may require creating a residual stress at the inner radii of the supporting jackets (30, 40, 50) such that the stress under load is compressive or zero.
