Scope Of Work

Scope of work:

Rig into place a GE LM2500, 25MW, combustion turbine generator (CGT), weighing 350,000 lb. The unit was recommissioned into an existing combined-cycle co-generation configuration that had been in layup. The unit was rigged into place inside the building using hydraulic sliders. Inside building, the unit was positioned and lowered onto existing cast-in-place anchors. A 70 ft. slide path with tight entrance into the building, consisting of approximately ½ in. of clearance, on each side between unit and building structural columns.

We previously removed a GE LM2500 and a GE LM6000 from this same facility in 2007, after which the steam generator and partially decommissioned station went into protective layup.

Unique Solutions:

We provided our client with an approach that resulted in an overall reduction in project schedule and reduced the costs by mitigating additional jacking maneuvers and crane mobilizations. We set the slider track in advance so that client could sequence site deliveries of major components starting with the 150,000 lb. ‘box’ which was placed on the positioned slider track seen in the images.

When completed, approximately two weeks following the slider track positioning, we returned to slide the now fully-assembled combustion gas turbine and generator package weighing 350,000 lb. along the 70 ft. path into the building in position to lower over the anchor bolts.
