FABRICATION OF 32 STOP LOGS
In need of stop logs on site within a few weeks, it was determined that other vendors were either unable to meet the schedule or unable to procure materials.
TurbinePROs offered services, typically outside of the normal scope, and utilized their vendor relationships to procure a fabricator able to meet the time line. The fabricator was able to go direct to the mill to cut logs to specified lengths ultimately saving time, welding, and labour. Phased Fabrication & Delivery Schedule: a 2-lot, phased fabrication and delivery schedule was recommended in order to expedite an initial lot to the site. The solution kept the project on schedule and avoided work stoppage. Workmanship | QA/QC: tight tolerances for parallelism, straightness, and flatness of +/- 1.5mm over 25 ft / 7.62m were required. Venting was incorporated along the 25 ft seam weld.
“TurbinePROs’ support and efforts in the supply of stop logs for this rehabilitation project ensured that the logs were delivered within a very tight time frame to allow the turbine disassembly work to proceed without delay. We could see the attention that was given to confirm fabrication details and the timely communications that kept the fabrication process on schedule.”

SOLUTION
Provided solution for procurement and fabrication of 32 stop logs in 2 lots to avoid delay and stoppage of turbine rehab project schedule
RESULTS
Stop Logs: 4,000 lb (1818kg), 7544mm x 305mm x 610mm
Unique Project Challenges
PROPER SAFETY VENTS
Concerned that lot 1 stop logs lacked proper safety vents for the hot dip galvanizing process, TurbinePROs collaborated with CIMA to field locate 136 vent holes. TurbinePROs & CIMA engineering updated the design of lot 2 stop logs to include vent holes in the fabrication.
