An innovative offer that helps improving the control of the dynamical behavior of offshore structures and also strongly reducing computing time… That is precisely what proposes now PRINCIPIA, a French SME located in southern France. Specializing in applied engineering for the offshore sector (oil & gas and renewable marine energy) and editor of reference software in the field, the La Ciotat-based company has successfully adapted one of its simulation codes, DEEPLINES, to high performance computing (HPC).

DEEPLINES, created by an efficient collaboration between PRINCIPIA and IFPEN, is a simulation code fitted to model the dynamical behavior of liaison structures between the bottom and the surface of offshore systems (for example, for risers, submarine cables,  pipelines, anchor points…). The control of the behavior of these structures is essential for optimizing their design as well as for ensuring their performance and their long term reliability. Yet, even if numerical simulation allows today a very accurate modelling, computing times rapidly become prohibitive when numerous testing conditions related to the different states of sea conditions (calm, rough or complete statistical representation of the sea states over the operational duration of the field) are taken in account. The use of HPC then turns to be mandatory to bring these tools in line with the constraints of draft plannings in the engineering phases.

Thanks to the support of the HPC for SMEs Initiative (now SiMSEO, see more information below), launched for helping SMEs to benefit from numerical simulation and HPC, PRINCIPIA was able to make use of a double kind of expertise: one from an Inria Sophia Antipolis Méditerranée team for scaling up its code and another from the Atos/Bull company as part of the European Fortissimo project for deploying its offer on a commercial cloud platform. By having adapted its code to HPC and by proposing it in an « on demand » mode, PRINCIPIA is now able to propose to its clients significantly faster computing times. Thus, DEEPLINES is the first code in this field of analysis to propose a cloud HPC version at international level.

Moreover, the results achieved also helped open the doors to the European HPC ecosystem. PRINCIPIA has been selected by the SHAPE program for adapting another of its codes dedicated to offshore engineering to the massively parallel systems of PRACE.

“Thanks to the efficient support in terms of advices, expertise and resources, we have been able to carry out our DEEPLINES HPC project and to rapidly bring to market an innovative offer that won immediate favor among industrials because of its double valuable impact on quality and deadlines”, Benoît Valleteau de Moulliac, CEO of PRINCIPIA, expressed.

PRINCIPIA’s approach towards HPC has been acknowledged by the first edition of the “Numerical Simulation Trophies”, created by Teratec with the French magazines L’Usine Nouvelle and L’Usine Digitale.
