Blind Test Workshops

Description and Aim

Numerical modelling has become an important process in the assessment of wave structure interaction problems and a vast number of tools have been developed as a consequence. The complete range of model fidelity is now available to developers with the common trade off between computational efficiency and model complexity (i.e. number of simplifications made to the physics being solved) being the main driver when selecting a particular tool for the scenario under investigation. Despite this, as discovered in the 1st CCP-WSI Focus Group Workshop, there still remains considerable uncertainty over the required level of model fidelity when using numerical methods to simulate the interaction of waves with offshore and coastal structures.

The CCP-WSI Blind Test Workshops have been devised to provide a better understanding of this issue and inform future development of numerical modelling standards. Within these Workshops, numerical modellers within the wave structure interaction (WSI) community will be invited to use their numerical codes to simulate a series of specific WSI problems covering the full range of relevant complexities. The details of each case will be introduced at an Introductory Event providing an opportunity for attendees to discuss the proposed test cases, refine them and register an expression of interest in participating. Following this there will be a Release Event in which all of the required information to reproduce a set of bespoke physical experiments will be published. The key outputs of the experiments will not be divulged until after the community have submitted their numerical results. A Showcase Event will then follow in which the results from the test and present recommendations will be shared with the community.

The CCP-WSI Blind Test Series'

There will be two CCP-WSI Blind Test Series':

The CCP-WSI Blind Test Series 1 will be held in conjunction with the International Society of Offshore and Polar Engineers (ISOPE) conference with the Introductory proposal being presented at the ISOPE conference in San Francisco, USA on Wednesday 28th June 2017. The Release of the CCP-WSI Blind Test Series 1 Test Cases will take place on Tuesday 29th August 2017.The Show Case Event for the CCP-WSI Blind Test Series 1 will be held in a special session at the 2018 ISOPE conference in Sapporo, Japan. The deadline for submission of results to the Series 1 Blind Test is tbc (an extended deadline of has been agreed for relevant abstract submissions to ISOPE 2018).

The CCP-WSI Blind Test Series 2 will be held in conjunction with the European Wave and Tidal Energy Conference (EWTEC) with the Introductory Event being held in a side event of EWTEC 2017 at 5:30pm on Tuesday 29th August 2017 at the University College, Cork, Ireland. The Series 2 Test Cases will be released In April 2018 and the Show Case event for the CCP-WSI Blind Test Series 2 will be held during a special session at the 2019 EWTEC.
