Richards Bay – Floating Wave Attenuator

With barges and ships passing by frequently, creating up to 1,5 meter wakes, this 800 meter long floating wave attenuator made up from 20 by 5 meter pontoons was installed 2012 in Richards Bay, South Africa, to protect the sensitive mangrove area from erosion.

To be able to accomodate the conditions of 1,5 meter waves, 3 meter water level variation, 0,5 m/s current and a muddy and sloping seabed it was designed to use 200 units of Seaflex model 6035 TSBP (6 hawsers, 3,5 meter long per unit with ByPass) along with 3200 meter of our high quality polyester rope, anchored with Helix embedment anchors.
