Seakeeping and sloshing

Much of Bureau Veritas’ Research and Development (R&D) work involves improving our understanding – and that of our clients and partners – of hydrodynamics. We work closely with both ship owners, offshore asset owners, engineers and others to model wave loads and assess their impact, using our understanding of fluid dynamics. With this knowledge, we can evaluate fluid interactions, help reduce sloshing risks and improve the overall integrity of an asset.

Our in-house software provides a powerful and independent verification of our clients’ own calculations. Both HYDROSTAR and FOAMSTAR have been developed and updated based on the outcomes of our ongoing R&D endeavors.

Our Projects

CHAIRE ECN

#UserGroups #Marine
Bureau Veritas has collaborated with the Ecole Centrale Nantes in the creation of an industry chair to investigate the ships of the future. Our research covers three main aspects:
•Ship safety
•Interacting bodies and flexible connections
•Wave performance

PT PH49 / PT PH50

#Seakeeping #StructuralIntegrity
PT PH49 and PH50 are IACS initiatives to derive new wave loads from the new North Atlantic scatter diagram. This work will enable an update of CSR, S11 and S11A and the assessment of new wave loads and corrosion margins.

HAWA-III

#JIP #Offshore
HAWA-III is a Joint Industry Project (JIP) to study hydrodynamic loading in shallow waters to develop calculation procedures for the offshore energy industry. We’re seeking to extend and validate the overall design methodology of nearshore terminals and provide practical tools and guidelines to apply it.

Our Software

HYDROSTAR

#Software #Marine
HYDROSTAR is our state-of-the-art seakeeping software. It was developed to compute first- and second-order wave loads and vessel responses, in both frequency domains or time domains.

FOAMSTAR

#Software #Marine
FOAMSTAR is our in-house computational fluid dynamics (CFD) software. It is based on the openFOAM open-source software, complimented by our own developments for specific seakeeping and sloshing applications and hydro-structure coupling.

HYDROSTAR-V

#Software #Marine
Hydrostar-V will be a new in-house seakeeping software, based on boundary integral equations. It includes a new formulation of the Geen function, which includes some dissipation effects.
