A method of constructing a thin-walled pressure vessel having a localized area of increased wall thickness is described comprising the steps of: forming a thermoplastic insert having an aperture; forming a thin thermoplastic inner liner having a substantially cylindrical middle portion, first and second end portions connected to the middle portion, and a recess in the middle portion disposed inwardly; securing the insert into the recess to substantially fill the recess and form a substantially smooth and curved surface with the outer surface of the inner liner and form a localized area of increased wall thickness; inserting a locating marker in the aperture of the insert; forming an outer layer substantially covering the insert and the inner liner; securing a reinforcing patch to the outer layer over the locating marker; making an aperture through a portion of the reinforcing patch, the outer layer and the inner liner to complete a port through the localized area of increased wall thickness to the interior of the vessel.
