Part of: Waterpower '91: A New View of Hydro Resources
DBS Escher Wyss Inc. is building the largest turbines ever to be manufactured in Canada for the third expansion of the Tarbela project in Pakistan; four (4) Francis turbines each rated at 432 MW output with a runner diameter of D1 = 7.9 m. This paper describes how the organization addressed the contract requirement which called for an extreme short delivery schedule of the first and the subsequent units: The execution was driven by an aggressive in-house fabrication strategy, supported by selective subcontracting. Significant up-grading and additions to the manufacturing facilities, adjustment of the available human resource skills and an immediate response to technical difficulties were essential to begin the execution of these challenging components.
