Front Energies has developed an efficient CFD-based Numerical Wave Tank with wave coupling by new High-Level Spectral method and Mooring / Riser coupling by open-source software

​

Why Numerical Wave Basin?

​

• Verification and calibration of GP tools by physical model test or CFD is an essential part of offshore floater design

• CFD-based Numerical Wave Basin can save time and cost of the verification process

​

Status Quo

​

• Full 3-hr simulation in NWB takes 3 – 5 days.

• Longer simulation time raises other costs

​

FE Numerical Wave Basin: FE wave©  

​

• 3-hr GP simulation in one day

• Wave coupling by new High-Level Spectral (HLS) method

• Mooring / Riser coupling by open-source software MoorDyn in parallel

• More than 10,000 times less data storage

• Parallel Time Segment technique to reduce computing time by factor of 35%

 

Applications

​

• Global performance and air gap analysis

• Screening of wave impact events for wave impact simulations
