Wade Walker was awarded a contract by Alstom for work packages on the Kusile wet flue gas desulphurisation (WFGD) project. Alstom is responsible for the entire WFGD installation on Kusile while Wade Walker is responsible for three packages related to the WFGD, for Eskom’s most technologically advanced coal-fired power plant. The Kusile power station will be the first of its kind in South Africa to install the state-of-the-art WFGD technology, which removes sulphur oxides from the exhaust flue gases.

The Wade Walker project at Kusile involves the turnkey design, supply, installation and commissioning of the three work packages. In addition, it is responsible for verifying the electrical and instrumentation design undertaken by a third party.

The design of the earthing and lightning protection has been completed and submitted to the customer for review. All lightning designs comply with the international IEC 62305 standard as well as the locally developed SANS 10313 standard, ensuring the highest level lightning protection is in place. The lighting and power designs are also complete and are awaiting approval from the customer.

Site establishment is scheduled for the second quarter of 2014. The construction programme allows for simultaneous work in all areas pertinent to the project. “Our intention is to maintain a small, skilled,” Gordon Sneddon, general manager at Wade Walker, says.

“A core and fundamental operating philosophy of Wade Walker is to develop skills levels throughout the organisation. On the Kusile WFGD plant project this will include the training of four technicians and eight engineers,” Sneddon points out.
