Commercial multi-purpose CAD/CAM system VISI® as well as ship-specific systems like AutoShip® are employed. Since customer's information on investigated ships is supplied in a variety of formats, in-house numerical tools and procedures have been developed for transforming the data to meet the fairness and precision standards for ship model manufacture.

CFD tools are continuously being developed and applied in all research areas of BSHC. See also Ship Powering, Ship Dynamics and Ocean Engineering , Coastal Engineering.
This allows a cost efficient analysis of the hydrodynamic performance of ships and marine structures and advises potential improvement.
BSHC operates one of the world-leading CFD codes: Fluent 6 of Fluent Inc.

The every day tool of BSHC for resistance and flow analysis and hull form improvement is the code v-SHALLO , product of Hamburg Model Basin (HSVA)

 

For solving tasks, connected with flows ( inviscid, laminar, turbulent) around “hull – rudder – propeller” systems, as well as with prediction of cavitation in the propulsion systems in BSHC the Program Package STAR CCM +/ Design of CD – adapco is adopted having following turbulence models:

•  Large Eddy Simulation – LES;

•  Reynold's Averaged, Navier – Stokes (RANS);

•  Detached Eddy Simulation – DES;

•  Wall treatment models.

Programme packages used in the field of ship & offshore dynamics

The MORA suite of programs is based on the 3-D diffraction theory and is intended for calculations on dynamics of floating and fixed bodies and structures of arbitrary forms, with possibilities for accounting for joint action of environmental conditions – wind, waves and current, estimation of tension forces in mooring lines, multi-body interaction, evaluation of forces acting in the structure and its elements.

The ROMEO program package is intended for performing quasi-static and dynamic analysis of coupled drilling risers and mooring systems, which is of utmost importance for operation and safety of marine structures, including survival conditions. The product allows time-domain modeling of mooring systems dynamics and ensures compatibility with international industry standard safety codes.

The HECSALV suite of programs is made up of a number of main modules that c omprehensively cover ship static and dynamics modelling, initial design analysis , intact and damaged strength and stability , salvage and emergency response decision support .

 

Data acquisition and statistical processing during and after model tests is carried out by custom scientific interface software. The software works in a NI Lab View® and TestPoint® environment.
