Training Pool of Yangon, Myanmar

  • Area: 208m²

  • Wave Ball size: 150F

  • Free board height: 64cm

  • Anchor type: 3 points

The Uniteam Offshore Training Center (UOTC) training pool in Myanmar is a 16 x 13 meters wide with a shallow area of about 3 x 16m at one of the length side. The particularity of that training tank is that under the advice of Survival Systems Limited, it has been built with a particular shape of freeboard. That training pool had already some existing build in anchorages spread all over the surface of the floor. We wanted to use those anchorages in order to spare further drilling.

At first sight, the shape of the freeboard may look problematic for the resonance and thus for the waves formation. In fact, this shape plays as a deflector and prevents the water to overflow the beaches while giving some good splashes back to the trainees inside the training tank.

Taking into account the other activities, we choose to place the Wave Ball in one of the corners with a 3 points mooring system, using the existing built in anchorages of the training pool. The 3 ropes, starting each ones from an anchorage, joined together at -1.5m under the Wave Ball. From there starts the elastic rope to the Wave Ball.

The electrical configuration is as shown on the drawing here below.

As the electrical cabinet could be placed close to the pool and thanks to the small depth (3m) the cable of the Wave Ball could run along the floor and the wall in order to reach the electrical cabinet while staying under the maximum length of 25m.

Several patterns were reached and from those which have been programmed, a beautiful low mode and an astonishing rodeo mode.This latter selection creates rough and irregular wave patterns such as may be found in the ocean.
