Hayward Tyler Group has completed the onsite overhaul of four of its boiler circulation pumps (BCPs) at the Masinloc coal-fired power station in the Philippines.

The overhaul was completed by Hayward Tyler Service Division (HTS) in 40 days, which the company said was a real achievement as a typical mechanical overhaul of one BCP, including electrical rewinding, normally takes 30 days to complete.

The work followed a similar task at the same facility in March 2008, which again saw the company overhaul two BCPs in 35 days.

This type of onsite overhaul work depends heavily on the availability of spares at the site.

The procurement of spares alone can take 10 to 14 weeks.

Through good teamwork, spares were procured by HTS in eight weeks, enabling onsite work to progress as planned.

The Masinloc coal-fired power plant (Masinloc CPP) is a 600MW power plant located in Masinloc, province of Zambales (Island of Luzon).

Masinloc CPP installed BCPs from Hayward Tyler in 1996.

The power station, which is now owned by Masinloc Power Partners (MPP), a subsidiary of AES in the US, was originally a government-run facility.

A lack of expenditure on planned maintenance prior to the takeover by AES meant that the BCPs had been poorly maintained.

On site, there are two boilers and seven Hayward Tyler BCPs, each boiler nominally requiring three BCPs, with an additional BCP as standby.

Before HTS conducted the first overhaul and rewind work in March 2008, the remaining BCPs had been running continuously for a number of years.

With a lack of any planned maintenance, the number of pumps in service was, in some cases, reduced to two pumps per boiler, rather than the nominal three pumps.

The overall condition of the units had therefore deteriorated and had run into a state of disrepair.

Anil Patel, export sales engineer at HTS, said: ‘The AES takeover period was controlled but added a further period of time during the condition of suspension, which allowed a further degradation in the condition of the plant.

‘However, provision and coordination with AES enabled the rapid release of orders and financing to initiate the supply of goods and services from HTS to support the extensive maintenance programme that followed the handover.’ Hayward Tyler rotating equipment service centres are capable of providing outage, repair, overhaul and test services for boiler circulating pumps, subsea motors, submersible pumps, canned pumps and steam turbines, from a variety of manufacturers and industries.

Services provided include: canned and wet motor overhaul and rewinds; pump, submersible pump and general purpose steam turbine overhauls; large in-house resource centres; welding; balancing; machining; comprehensive engineering review; and material, performance and reliability upgrades.
