Partners joining us in R&D phase

We have partnered with different high-end parties to develop our revolutionary wavepool technology to generate surfable waves. With our background in wave energy & off-shore industry, we understand the hydrodynamics of waves. Because, the same laws of physics apply to the absorption and creation of waves.

LakeSide Paradise

To have a better idea of which waves different levels of surfers expect, we have enlisted the support of Lakeside Paradise. Founding father and surfing pioneer Frank Vanleenhove brings in years of surfing experience worldwide and extensive knowledge on surfers’ expectations & desires.

“After following the wavepool evolution for many years all over the world, AllWaves appeared as a real revelation with a unique and never before seen technology. Both sustainable and safe, AllWaves produces waves for everybody in a more natural environment than any other system.

AllWaves also presents a realistic financial plan when it comes to construction and commercialisation.

AllWaves will blow the minds of the surfing world and beyond!

After Belgian Beer and waffles, it is now time for Belgian waves!”

The offshore sector is characterised by high performance demands. VAPO understands the cost of failure, so they make sure energy efficiency, safety, high reliability, and sustainability are top of mind when designing and executing operations. Moreover, the group is also active in the leisure industry (e.g. roller coatsers) and understands our requirements in terms of delivering uptime guarantees to our clients.

Coastal & Ocean Basin

Additionally, we can count on the Coastal & Ocean Basin (COB). The COB is a consortium of the Universities of Ghent and Leuven and Flanders Hydraulic Research Institute. They support us through academic research, knowledge sharing and performed in-depth experiments. They have provided the scientific grounds for the uniqueness of the AllWaves reef setup.

Blue Cluster

This collaboration initiative is facilitated by Blue Cluster. The Blue Cluster is an independent Belgian organisation that groups private companies with the purpose of developing and promoting economic activities linked to the sea. The Blue Cluster is recognised as a spearhead cluster by the Flemish government and focuses on several aspects of the sustainable blue economy, including blue tourism.

Major step towards opening show room

Status wavepool

We are preparing our wavepool demo center in Knokke-Heist. Civil works are succesfully completed and the team started installing the wavepool machine (also known as our wavemaker). We are more than proud with the support we receive from the community of Knokke-Heist, Belgium. Today, the installation of the high voltage cabins to power our wavepool is a fact. Also, we will be using renewable energy to supply energy to our wavepool. This is a major step in demonstrating our technology to the world. The construction of the basin of 100 by 100 meter started in August 2021. Now, we are ready for the next steps. With the grid connection in place, we now can proceed with the installation of our wavemaker. Next, we will run the necessary dry tests before eventually filling the wavepool with water.

In Knokke-Heist, innovation and sustainability are high on the agenda. Besides, we are the surfing municipality par excellence,” says Mayor Piet De Groote. “AllWaves’ innovative and unique project immediately appealed to us. We are very pleased that the test facility will be opening in summer 2023 to demonstrate the uniqueness of the technology. Network operator Fluvius provided the right electrical capacities and just realized the electricity connection. That is an important technical milestone to be able to showcase the technology.”

We plan to open our show room in summer of 2023. Belgian surf pioneer Frank Vanleenhove, founding father of the famous water sport clubs Surfers & Lakeside Paradise, brings in his surfing experience. Together with international experts representing the surfer’s community, they will help us further fine tune different waves profiles for all levels of surfers.

Of course, potential B2B clients (site operators, developers, investors…) from all over the world will be exclusively invited to personally test & experience our waves. This is a crucial phaes in their technology decision process.

Unfortunately this demo site will never be open for the general public or for commercial surf park operations. The location in Knokke-Heist remains a showroom to demonstrate the innovative AllWaves technology. However, in parallel we have several plans to build a commercial site as soon as possible in Belgium.

How to avoid backwash and wave reflection

AllWaves reefs are specifically designed to avoid backwash and wave reflection.

AllWaves reefs are specifically designed to avoid both backwash and wave reflection. With this purpose in mind, the Coastal Ocean Basin (COB) has created the scientific ground for the AllWaves reef setup. The Coastal Ocean Basin is a consortium of the Universities of Ghent and Leuven, and Flanders Hydraulic Research Institute.

But how to avoid backwash and wave reflection in a wavepool

In 2020 we started off with experiments in COB’s wave flume facility. This concrete wave flume is 30m long, 1m wide and 1.2m high. Under those circumstances a 2D slice of the passive wave absorber system can be investigated. Based on desk research that has been performed prior to the tests, a passive wave absorber system was selected. This was subject to further investigation in terms of both reflection coefficients and backwash velocities. In short, the experimental set-up, test matrix and analysis results serve as design guidance for the passive wave absorber system (reef) in our test surf pool in Knokke-Heist.

“Generating perfect wave conditions in recreational surf pools depends on the wave generation system and wave transformation phenomena. Backwash results in steep cross waves and confused wave conditions. Our experiments have led to a state-of-the-art solution delivering a generic reef, where more than 90% of the remaining energy is dissipated.”, says Prof. Peter Troch and Dr. Maximilian Streicher, Coastal & Ocean Basin, Ghent University, Belgium.

It is specifically designed to avoid backwash and wave reflection. This results in soft slopes where incoming waves break and disappear seamlessly. After an AllWaves wave breaks, the water flows back into the pool without disturbing the next perfect, rolling set of waves. Thanks to that, there is no need to interrupt the surfing session to calm down the water. Waves can roll non-stop. And the entire system has an optimized energy efficiency.

To conclude, the abscence of backwash and wave reflection is above all interesting for surf park operators to obtain a commercially viable business model of their wavepool. On the on hand, no wasted time between waves, means surfers can keep surfing, and everyone can catch at least 15 waves in a 1-hour session. On the other hand, no trailing waves means no wasted energy, so optimized operating expenses.

Scale models to create the perfect wave

At AllWaves we intensively use scale models to create the perfect wave. The key to building any new, groundbreaking & innovative technology is following a step-by-step process and lots of prototyping. That is why we draw knowledge from the widely known NASA TRL methodology. Technology Readiness Levels (TRL) are a type of measurement system used to assess the maturity level of a particular technology. In our 1/10 and 1/20 scale models, we evaluated different wave profiles and materials to use. We look at both wave heights and speed, but also shape and everything in between. Such as backwash & wave reflection.

For an expert opinion, we brought in Belgian surf pioneer Frank Vanleenhove, the founding father of the surfclub “Surfers Paradise” and the sister company “Lakeside Paradise”. Frank brings in years of surf experience. Through his early-stage involvement, we integrated surfers’ expectations towards waves in a wave pool and embedded that in our design. As waves of 2 m are in the model only 20 cm high, the evaluation consists mainly of a visual check of the different wave profiles. We looked at 48 different profiles considering all level of surfers with different skills & preferences. From beginner to pro.

“Most people focus only on the shape of the lip, the shoulder, the pocket and tube of a wave when observing a wave. To be able to know whether a wave carries enough energy to surf on, you need also to focus on the waves’ backside. We want to see a rather flat shoulder with a vast amount of water that pushes the face in a perfect way (see picture). Secondly, we want to see what happens in the area just in front of the face. When water is sucked into the wave, we experience the wave as a qualified wave”, Steven Nauwelaerts (our CEO) explains.

When energy is not transferred correctly between the wavemaker and the water, trailing waves are created. These are extra waves in between the actual surf waves. Trailing waves represent wasted energy, reduced efficiency and an unpleasant surf sensation. “In none of the settings, we observed trailing waves.“, Frank explains. “I can’t wait to go and catch the waves in the full-scale demo centre. The countdown has started”.
