OPERATION & MAINTENANCE OF POWER PLANTS
the service life of vital pumping assets at a power station. Sulzer’s resources and expertise also delivered overhaul projects for high voltage motors at the facility. Electricity plays a vital role in everyday
W
life, powering industrial and domestic equipment. Meeting this demand requires careful management of the assets involved in producing electrical power. Coordinating generating capacity with maintenance requirements is a delicate balancing act, and one that benefits from minimal downtime.
QUALITY AND TIME OPTIMISATION Te power generation industry appreciates the advantages of high- quality workmanship in prolonging asset performance and increasing reliability. One of the procedures used to minimise delays and optimise maintenance tasks is the framework agreement. Tis establishes a short-list of suppliers that have shown they meet the required standards for workmanship, health and safety as well as management procedures and cost efficiency.
As an approved supplier, Sulzer can be asked to quote for maintenance projects in the knowledge that it has already met the necessary criteria. Tis can reduce the time to repair important assets and maintains the high standards of the generating plant. Another example of time optimisation
is to remove large assets, such as pumps and motors from service and
orking through a framework agreement has ensured that high quality repairs were delivered on time, extending
The cooling water pumps provide an essential service for power stations
R REDUCINGEPAIR TIMES
Power station reduces downtime by using pre-approved supplier for maintenance
overhaul them as part of a preventative maintenance strategy. Sulzer has been involved in such projects with several power generating sites throughout the UK and now has a number of framework agreements that are managed by the service centres closest to the customers’ sites.

CASE STUDY: HIGH VOLTAGE PUMP MOTOR OVERHAUL As the initial point of contact, the local service centre coordinates all of the assets and personnel required to deliver the project through the comprehensive service centre network. A good example is the recent overhaul of two high-voltage motors, one from a cooling water
pump and the other from a boiler feed pump.
Both motors were disconnected and
removed from service by engineers from the Avonmouth Service Centre, which is located close to the power station. Te refurbishment work was completed by the Southampton Service Centre with additional expertise provided by engineers in Birmingham, where the motors would be finally tested before being returned to the customer. In this case, the boiler feed pump motor had a history of high partial discharge readings in the windings and action was required to manage the situation and extend the useful life of the windings. Tis would allow the power
