The paper presents details of five of these vessels, but uses the results of all the 26 vessels to produce a design chart. The investigation found that ANSYS was unreliable due the restrictions of the non-commercial version of ANSYS that was available at the authors' university. In contrast to this, the use of Conebuck, together with the use of plastic knockdown factors obtained from a previously available design chart, proved to be the better option. Moreover, the use of the in-house design chart was much easier to use than the ANSYS non-linear analysis. A new design chart is provided. ANSYS did, however, provided spectacular animation.

This paper will prove of much interest to any person or organisation with a vested interest in accessing the most hostile underwater areas of the planet. Whether it be for research, military or commercial needs, this paper details a potentially revolutionary way of constructing deep sea submersible ocean going vehicles/submarines. This is a detailed account of how the theory of using corrugated re-inforced submarine pressure hulls along with the ever emerging world of composites can allow submersible vehicles/submarines to access the deepest depths of the world's oceans.

The paper describes the process of accurately measuring corrugated specimens and how to carry out hydrostatic pressure testing of these specimens. It provides a thorough guide of the mathematical analysis in order to safely calculate theoretical buckling pressures and a well populated design chart. Descriptions of the finite 1 element method and the use of the Ansys13 software are also covered. Observations, recommendations and future points of consideration provide additional insight into the field and will be beneficial for those who wish carry out further investigations or analysis of the concept.
