Hydrodynamics
Technical Bulletin 2013

Summary

Strategic long-term research into hydrodynamics continued this year using the BV sea-keeping software HydroStar. Several new features were added, while overall computational efficiency was improved. The number of users worldwide continues to grow, ensuring that HydroStar retains its market-leading role.

International co-operation is of vital importance to the research and development activities of BV’s hydrodynamic team. In 2013, we actively participated in a number of different JIPs, the results of some of which have been published jointly with CSBC Corporation Taiwan, Harbin Engineering University, Harbin Institute of Technology, Dalian Technology University and Petrobras R&D Centre. The subjects covered included second-order QTFs, FLNG systems, water column motion in the large turret of FPSOs, and sea-keeping-sloshing coupling in containerships for sea trial purposes. In addition, a variety of more theoretical work was undertaken, including Green shipping initiatives.
