Wisemans Surf Lodge is a world class resort located on the Hawkesbury River about 1 hour drive from Sydney.  The development comprises the Wisemans Retreat, including a 54-room accommodation complex, conference centre, licensed restaurant and the Wisemans Ferry Golf Club.  The centre piece of the resort is a 12,000 square metre wave pool boasting a primary wave producing 2.0 - 2.5 metre waves, and a secondary 1.0 metre peak mid way down the pool.  

​

Mr Ben McCarthy of Balnce engaged Adaptint to design and develop a dynamic simulation of the proposed wave options and operating modes for the Wisemans wave pool. A digital twin of the pool was designed that included a dashboard allowing the user to vary key parameters including the following:

​

  • Selection of wave size 

  • Wave type 

  • Number of waves per set 

  • Time between waves

  • Time between sets

  • Paddle speed

  • Number of surfers on each break - and more

​

The digital twin was designed to support analysis of possible operating modes with the objective of finding the optimum number of surfers the pool can support at any time.   The model must ensure that all surfers catch a predefined minimum number of waves in a hour whilst minimising the number of unridden waves in a session.   The user is able to vary any of the above listed parameters and observe the impact on the average number of waves per surfer and the number of waves generated when no surfer was available to catch them.   

​

The model also has several optimisation experiments using the built-in OpQuest optimiser.  These experiments run multiple iterations of a base operating mode at high speed whilst randomly varying the model's parameters within upper and lower bounds.  Each experiment is designed with an objective function that seeks to maximise the number of surfers, minimise unridden waves and ensure that average waves per surfer targets are achieved.  When the optimisation is complete, the model reveals the optimal operating value for each parameter that will ensure the desired objectives are achieved.

Using the digital twin, Balnce were also able to validate possible wave options.  Selecting a wave configuration and then observing the location of surfers dynamically, provided insight on possible issues where surfers could find themselves in wave impact zones when paddling back out.  

​

The model also enabled Balnce to analyse the impact of surfers 'wiping out'.   A person falling in the take-off zone may lead to waves being missed until the surfer has been able to collect his/her surf board and paddle out of the area.  Controls on the experiment dashboard allow the user to manipulate the % of wipe-outs.  This can be used to simulate - for example - a group of surfers comprised of varying skill levels.  Less experienced surfers may be more likely to wipe-out.  When a 'surfer' wipes-out, the user can observe the surfer paddling out of the take-off area, including the length of time required before the zone is safe.  The model collects statistics showing the number of waves missed due to a surfer in the take-off zone.  This can be used to inform decisions such as the time between wave pulses and surfer return paths. 

​

​

Wave pools are complex systems.  Gaining a complete understanding of the many dynamics and permutations can be a real challenge.  Dynamic simulation modelling can provide insights that can remove the uncertainty helping you to make the right call.
