Overview

The project addressed the aging parts of the two 9E gas turbine units, which power the 360MW plant.

The challenge

This modernization represented one of the most complex and comprehensive inspection and repair projects for GE’s 9E gas turbine in China. It was also the most complete inspection of the gas turbine, through overhaul, and necessary replacement for all detachable parts, which made up more than 300 items.

The solution

GE and Shenzhen Baochang worked together to implement safety procedures aiming to ensure the timely and safe completion of the outage at the site.

The COVID-19 outbreak brought unexpected and unprecedented difficulties for our inspection project, and GE’s ability to do it safely and in a timely manner was critical to the success of the project. Additionally, our 17-year experience with GE’s proven technology and our past experience with its top-level and professional service through the Advanced Gas Path inspection and upgrade conducted on our last unit made them the best choice to meet our requirements.

The initial schedule was for 35 days but was extended to 69 days due to the customer’s expanded work scope and the 14-day quarantine before the project commenced. Engineers from GE and FieldCore quickly implemented measures aiming to ensure the safe and steady operation of the outage and delivered more than one day ahead of schedule.

In Shenzhen, Guangdong Province, GE has the largest installed base for the 9E gas turbine in China. In April 2019, GE announced that it had successfully completed the world’s first installation of its DLN1.0+ with Ultra Low NOx combustion upgrade on nine GE 9E gas turbines at five power generation enterprises to help improve air quality and public health throughout China by reducing nitrogen oxide (NOx) emissions.
