Summer Projects are Heating Up!

We’ve been going strong all summer!  Hard to believe August is almost here.  We’ve had our crews at 32 different customer sites across the U.S. so far this summer… and counting.  Typically summertime brings a slow down for maintenance as turbines and generators across the country are in full operation for peak run season.  But we’ve had a solid summer, and we’re gearing up for a busy fall outage season.  If there are any turbine maintenance inspection or repair projects you’re considering for this fall please give us a call – we’re ready and willing to help however we can!

Outage Planning Services

Pre-Outage Planning

A Customized Plan

Most power producers are short-staffed and do not have the time and sometimes the expertise to prepare a comprehensive outage plan and workscope.  That’s why we offers the option of providing our comprehensive Pre-Outage Planning Service independent of the award of the contract for inspection and repairs.

Our field project teams have the breadth of knowledge and experience to produce the highest quality planning product, with a workscope customized to your unit and its specific signature.

One of our qualified Technical Directors will visit your plant and prepare a customized report for your specific unit.  The report will contain everything needed to plan your internal preparations for the outage and to prepare a comprehensive Request for Quote for the inspections and repairs.

 

A Basis For Your RFQ’s 

Your customized Pre-Outage Plan will include everything you need to prepare a comprehensive Request for Quote for the necessary inspections and repairs.  We will compile a summary of the findings from past inspections and develop a list of recommendations for potential repair work.  We will prepare a comprehensive and detailed suggested Statement of Work for the outage, based on these findings and observations from a unit walk-down.  Incorporating this information into your Request for Quote packages will yield “apples to apples” cost comparisons and few if any surprises on implementation.

 

A Task List For Your Facility

We will review your spare parts inventory and compile a list of recommended parts to have on hand prior to the outage.  We will recommend disposal of any expired or unusable spare parts.

We will also prepare a Critical Path Method schedule based on the defined workscope.  You can use this schedule to plan your expected outage duration and coordinate with any other activities to be conducted during this downtime.

 

What We Provide

The Pre-Outage Planning Package includes:

  • Outage History Review: We review your past outage reports to determine pending or implemented outage recommendations and any changes that may have been made to your unit.
  • Unit Walk-down: We perform a detailed walk-down of the unit, visually inspecting the components and auxiliaries that will help to develop a detailed pre-outage scope of work.
  • Customized Outage Workscope: Formulated from the on-site analysis of your unit, past outage reports, and known issues supplemented by discussion of particulars with you and your staff, we develop a workscope unique to the specifics of your unit and its current condition.
  • Outage Schedule: We take your customized workscope and create a comprehensive Critical Path Method schedule. This exceptional tool outlines a reasonable outage schedule and projected duration, and it can be used as a guide to measure the performance of your outage contractor.
  • Parts List: We compile a “recommended to buy” list determined by a physical review of your unit, prior outage report recommendations, and review of available inventory.

 

In summary, our Pre-Outage Planning deliverables to you will be:

  1. A scope of work tailored to your equipment and outage needs.
  2. A parts inventory and suggested purchase list (to support outage or emergency needs).
  3. A document to assist in the preparation of the scope for RFQ / bid documents.

  • Quality: PSG is so confident in our quality that we can offer a one year warranty of our work, including our PSG contracted suppliers.  This means that if you suspect a deficiency in our work on your outage, we will immediately come out to investigate.  If we find that the problem is our responsibility, we will immediately mobilize all resources necessary to correct the problem, at no cost to you.

If we find damage or deviation to specification, we perform a full assessment to diagnose the root causes behind the symptom and recommend actions to prevent its return.  These recommendations may include operational or maintenance changes.  The goal of our comprehensive measurements and proactive approach to repairs is the elimination of future forced outages.

Trust PSG and our experience in serving any of your power generation needs. Contact us today for more information.

On-Site Turbine Repair Services

If it is beneficial to you to have turbine component repairs performed on-site, we offer our portable equipment to be ready when components are removed from the turbine.  Contact us today to reserve our portable repair equipment to be on-site for your next turbine outage.

Wind Turbine Machining

We recently completed another uptower wind turbine shaft machining project.  Our equipment and personnel will travel to wherever the problem may be.  For the wind industry, it happens to be 200+ feet above the ground, but we’re happy to do this on your turbine deck or any other area in the plant as well.  Please give us a call if you have any emergent shaft machining needs, we’ll respond quickly and get your equipment back up and running.  For more information on our wind turbine specialty machining services please CLICK HERE.

 

Before

 

After

Frame 5 Major Inspection

We were contracted to perform a Major Inspection on a Frame 5 Combustion Turbine for an Independent Power Producer in the Northern U.S.  Upon arrival the unit was shut down and locked out to prepare for the upcoming inspection. The necessary roof sections and inlets were removed for crane access to remove components. All combustion hardware was removed during the inspection – liners, cross fire tubes, and transition pieces.

During disassembly there was a great deal of broken bolting experienced on this unit, mainly due to the fact it is an outdoor unit that has not been disassembled in many years. These broken bolts were removed by a local vendor as well as the repair of the threaded holes. The combustion hardware was not in great condition, with cracked liners and high wear on the fuel nozzles.  The crossfire tubes were severely worn. Exhaust cooling air piping was also found to be severally corroded.  The inlet access door was removed for inspection of the inlet and the IGV’s. The IGV angles and clearances were checked and verified.  The row #1 compressor blade tip clearances were also checked. The IGV’s were cleaned for inspection.  After the inspection the IGV’s with excessive clearance had the bushings replaced. The inlet was cleaned and visually inspected by our Technical Field Advisor and plant personnel prior to closing. The main oil pump was disassembled and inspected; bearings were scored so they were replaced with new ones from the customer. The spline shaft had moderate wear on the gear teeth, and was replaced as well.

The 9th stage hook fit was cracked and corroded which necessitated the removal of the aft compressor case. This section of the compressor case was removed and sent to a repair shop. Upon return to the site the aft compressor case was reinstalled with all bolting torqued to support the lower half.

All refurbished and new hardware from the customer’s inventory was checked, with serial numbers recorded and marked for location.

During the inspection all the upper half cases were removed as well as the upper half nozzles – 1st and 2nd.  The upper half bearings were disassembled, and the rotor was removed. The number 2 bearing was found to be severally worn and out of tolerance. This allowed the rotor to drop and rub components in the lower half of the turbine section. All of the used lower half parts were removed and new or refurbished parts were installed. The rotor was cleaned, refurbished stage 1 buckets were installed, and the journals were lapped, then installed with refurbished bearings. The customer supplied new or refurbished stage 1 and 2 nozzles which were installed during the outage. All of the upper half cases were installed; all bolts were torqued per specification.

 

After completion of the unit the LOTO was released and the customer prepared for the test run. We were released from site after the unit was at 5MW’s and had excellent bearing vibrations.

Another great project by our Operations team, and another satisfied customer!
