Workshop on Ship Scale Hydrodynamic Computer Simulation

Lloyd’s Register is hosting a ship scale hydrodynamics simulation workshop on 25 November 2016, at their Global Technology Centre in Southampton.

The workshop is open to all hydrodynamic modelling practitioners from industry and academia who are interested in improving the science of ship scale modelling. The main objective of the workshop is to compare results of modern numerical methods with Lloyd's Register's sea trials measurements, to assess and develop the capabilities of the numerical tools in ship scale and increase confidence in ship scale Computational Fluid Dynamics (CFD).

Getting involved with the workshop

Download files

Fill in this simple form to download the hull and propeller geometries of the subject vessel (16.9k DWT General Cargo Vessel REGAL) as well as simulation conditions which are identical to the sea trials records. The geometries are based on 3D laser scans of the propeller and hull and are supplied in STL format.

Simulate the case/s and send LR your results by October 25, 2016 

Send us blind numerical self-propulsion simulation results for the subject vessel for at least one self-propulsion condition. We also encourage you to calculate and submit resistance cases, propeller’s open water characteristics and a cavitation simulation. 

Results from all CFD codes, potential flow codes, marine simulator approximations and their set ups are welcome. We will provide you with a document in September 2016 that defines the format of the results to be submitted so that comparisons are unambiguous. 

Four modelling scenarios are proposed:

  • Ship scale resistance simulation (4 speeds). As there are no ship scale resistance measurements, all results will be compared against each other. This scenario is used to investigate the hull-propeller interaction coefficients. 
  • Ship scale propeller open water characteristics computations (4 speeds). As there are no ship scale open water propeller measurements, all results will be compared to each other. This scenario is used to investigate the hull-propeller interaction coefficients.
  • Ship scale self-propulsion simulation (3 speeds). The results will be compared with ship scale measurements performed by LR.
  • Ship scale propeller cavitation (1 condition). The visual cavitation pattern will be compared with ship scale high speed video recordings done by LR

Purchase tickets for the workshop

The workshop will be structured to go through comparisons of all scenarios and provide opportunities for participants to discuss the CFD methods applied. The deadline to purchase tickets from LR for the workshop is also October 25, 2016.
