The issue of this thesis is the creation of a complete project management template, about the TAP (Trans Adriatic Pipeline) (currently under construction). I have stated a matter related to TAP, but from the managerial approach to the project, i.e. project management from conception to operation. It is not a technical issue (e.g. construction of pipelines) but project management throughout its duration – from the construction phase and the viability study, the procedures for securing the transit lands, all phases of the studies, the corrections due to special conditions on site of the project, the construction of the project from an administrative point of view, testing, commissioning and operation with results of use. Diplomacy can include all of these or focus on one part or even just one if there is enough material. Following the recent developments in the energy sector due to the war in Ukraine it would be good to include elements of this side of the energy pipelines.
