The petroleum structural engineering (PSE) software is the engineering tool for the offshore and onshore industries. It is also the engineering engine of the virtual petroleum structures (VPS) new technology for offshore and onshore structures.

Through its multiple views, the VPS allows to carry engineering work, connection and weld design, as well as extraction of detail drawings and fabrication data from a unique database. With the VPS new technology, there is no need to use transfer protocols, nor to repeat model generation in the various phases of a project.

The PSE software is used for the design and rehabilitation of drilling structures for the offshore and onshore industries, including drilling masts, derricks and substructures. The software accounts for wind loads, vessel dynamic motions, wave and current loads.

Wind loads, based on the velocity component approach, and vessel dynamic motions are defined according to API 4F Specification for Drilling and Well Servicing Structures (3rd edition).
