Training Pool of Port Harcourt, Nigeria

  • Area: 312m²
  • Wave Ball size: 150F
  • Free board height: 60cm
  • Anchor type: One point

The tank in the Opeans Nigeria Limited Rescue & Survival Training Center in Port Harcourt is 25x12.5 meters wide with a shallow area of about 1m and a deep area of 3m. This pool, as many others, had no freeboard (pic 1).

 

We were contacted in order to make waves of 0.5 m high but only in half of the tank. At that time, the client did not know what to choose between a classical wave system and the Wave Ball.

In order to make the waves only in half of the pool, a separa­tion wall was proposed as on the drawing here below (fig 1). With an area divided by two, the Wave Ball model that was chosen at that time was a W150FL.

As they did not want to separate the tank in two parts, it has been chosen to have waves in the whole pool. The Wave Ball size was then decided and turned to a W150F.

 

In the same time, they decided to forget about the classical wave machine which required a lot of arrangements in a pool where the available building area was limited.

 

Taking advantage that this tank had to be renewed (pic 2), they built a 60cm high freeboard all around the perimeter. They kept the old skimmer filtration system that was compatible with wave formation as it does not perturb the resonance.

At the same time, they placed the anchor for the Wave Ball at the position defined by WOW Company following the computer simulation (pic 3).

The Wave Ball has been installed and programmed in April 2011 (pic 4).
