Seakeeping and sloshing

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.

EVAP

#Marine
EVap is a co-operative research ship project looking at extreme value predictions to better anticipate ships’ behavior at sea.

DIMPACT+

#MRE#JIP
This project aims to explore in depth the assessment of extreme striking wave loads, also known as "slamming loads", on fixes and floating offshore wind turbines (FOWT). 

DIMPACT+ is a continuation of the previous DIMPACT JIP, which resulted in new methods for computing slamming loads on FOWT.

DIMPACT+ intends to improve DIMPACT’s slamming loads methods, extend them to bottom-fixed technologies with a focus on deep water bottom-fixed and shallow water with strong bottom slope, and develop a specific approach for the definition of the design sea states in presence of breaking waves.
