With more than 16 years of combined experience in managing a wide array of power plant projects, the team in our power generation division is known for delivering impeccable engineering, fabrication, construction, inspection, repair, retrofit and maintenance services for thermal power plants, co-generation power plants, combined-cycle power plants.
Aimed at assisting our clients on the upkeep and O&M (Operation and Maintenance) improvement of their existing fleets, HFS has developed the capability to service HRSG, IB, FH and coal boiler and provide technical solutions to a wide range of reliability, performance and emission issues.
Our engineer have much experienced, professional engineers can be supplied technical solution when client have issue or problem. HFS have been able to produce successful results for our clients, meeting, their needs on time and within budget while supplying quality products. HFS are worked same time zone with client.
HFS provides inspection resources, technology and software to provide the most thorough and comprehensive boiler inspections unlike any other boiler inspection company. HFS will provide the plant O&M team the ability to PRIORITIZE and MONITOR corrective action, tracking the status of all repair recommendations. HFS will provide detailed reports with analysis and predictive failure information to determine an accurate current and future state of their boiler systems, and repair recommendations to help minimize unscheduled (forced) outages. HFS ensures its clients a thorough and proper inspection is done on every outage, scheduled or unscheduled. And finally, HFS ensures repairs are done correctly with no “short cut” that would jeopardize the boiler integrity.
Basic Inspection Service
Visual inspection of pressure parts, gas path, steel structure and piping. HFS will carried out evaluation of the results and presenting inspection report with recommendations.
Pre-outage walkdown and punch list report based on findings and interviews
Thermographic survey to review casing, piping and identify leaks or faulty insulation
Recommendation for specialist Non-Destructive Examination (NDE) tasks to be performed during the detailed Boiler inspection (NDE to be performed by a qualified NDE technician)

General HRSG Inspection
A visual survey of the general HRSG condition, external casing, internal gas-side mechanical parts and auxiliary equipment. Readily accessible pressure part components are visually inspected. HISE recommends performing such a general inspection in addition to the basic inspections stipulated by local regulatory requirements.
Time frame requirement: 2 – 3 days HRSG accessibility.
Aligning HRSG Inspections for Optimized Availability
In order to prevent forced outages, periodic inspections should be conducted during scheduled outages. This allows the identification of component damage in the earliest stages – when there is still time to schedule a cost-effective repair.
HFS recommends a general inspection every 1 to 2 years and a more detailed inspection every 3 to 5 years. In order to optimize the overall plant availability, it is important to align these inspections with those of the gas turbine. Therefore, the detailed inspection should coincide with a gas turbine planned outage, e.g. the major or hot gas path inspection.
Detailed HRSG Inspection
Includes all the general inspection steps plus a more detailed visual inspection of all accessible pressure parts. This visual inspection will identify any areas of concern that require subsequent non-destructive examination (NDE) to be performed by HFS qualified NDE technician.
Time frame requirement: 4 – 6 days HRSG accessibility.
Walk down and punch list report based on findings and interviews
Thermographic survey to review casing, piping and identify leaks or faulty insulation
Recommendation for specialist non-destructive examinations (NDE) tasks to be performed during the detailed HRSG inspection (NDE to be performed by a qualified NDE technician)
Outage planning support
Supervision of repair or installation works
Visual inspection of Desuperheaters, blow down system, deaerator and valves
Review of any critical indications from the NDE inspections carried out during the detailed HRSG inspection
Documentation and evaluation of the inspection results, using OEM lifetime information management system database for efficient HRSG condition optimization
