Work with the six turbine manufacturers identified in this document – General Electric, Siemens, Solar, Mitsubishi Power Systems, Pratt & Whitney, and Rolls-Royce – to publish technical guidance addressing the safe cleaning of fuel gas piping supplying gas turbines. At minimum:
a. For cleaning methodology, require the use of inherently safer alternatives such as air blows and pigging with air in lieu of flammable gas.
b. Provide comprehensive technical guidance on inherently safer methods for cleaning fuel gas piping, such as the use of air or pigging with air.
