Scope of Work:
Remove and load onto trucks, two (2) 3,000HP Cooper LSV-12 gas engines from gas compressor station in Clendenin, WV.
- Remove two (2) 3,000HP Cooper LSV-12 natural gas engines driving KM-4 gas compressors
- Dismantle into major components prior to removal
- Two v-blocks
- Intermediate crankcase
- Lower crankcase – heaviest piece @ 45,000#
- Protect exterior ground surfaces from excessive weight
The units were disassembled into major components prior to removal. This was necessary to due to two multiple factors which include:
- Removing the units in whole would have required removal and relocation of significant mechanicals, utilities and ancillary equipment. Because this was a removal and replacement, avoiding these costs was beneficial to the customer and customers schedule.
- This was an active compressor station with substantial sub-grade pipelines, utilities and mechanicals; some of which had marginal cover. Consequently, ground bearing pressures were of a significant concern. Even limiting ground bearing to rigging primary component weights required plating 1,500 square feet of exterior grade with 60,000# of 1” steel plate.
- Several roads and bridges immediately local to the compressor station were structurally unable to handle the loads that would have been imposed transporting the units in whole.
- Overhead crane capacity in the building was sufficient only for 60% of the 45,000# lower crankcase (heaviest piece). We supplemented the OH crane with a Versa Lift 40/60.
