High pressure drilling manifolds

Team Stressman have performed several pipe and structural stress analyses of high pressure (HP) mud, cement and choke & kill manifolds. 

The pipe and structural stress in the mud, cement and the C&K manifold was calculated for an offshore drilling unit equipment supplier. As we like to look at the tasks from a system perspective, the stiffness of the structures and pipe supports was calculated as well as including the intermediate pipe routing between the manifolds was included. 

The stiffness was imported into the pipe stress analyses with a self-compiled macro system. This reduced the thermal expansion loads on the structure as the flexibility increased. The pipe stress and flange loads were evaluated in accordance with API 6A, ASME B31.3 and API-6AF2, and the structure in accordance with Eurocode 3. DNVGL third party approved the reports.
