The project was completed in less than three weeks, saving the plant lost dollars in operations and assuring continuous service to its customers. The procedure has been recorded by the customer for future reference.
Not only was the valve successfully opened, another critical goal was met: the Furmanite team conducted the job with minimal FM introduction. This was of utmost importance to Energy Northwest as particles in length of 0.2 to 0.4 inches can be detrimental to the reactor fuel integrity. As such, traditional drill bits were utilized to drill down to the valve body calculated minimum wall (half-inch remaining), allowing all FM to be removed prior to breaching the valve body. Drilling then transitioned to a hole saw to ensure the resulting FM was limited to a halft-inch thick, two-and-a-half-inch wide coupon and acceptable chip sizes. Due to adequate seating conditions on the 24-inch valve, there was little pressure to vent so the Furmanite team was able to clear the cavity of remaining FM before pressing into the seat with a customized anti-skid device that eliminated the drilling of the gate and further eliminated any additional FM from entering the system.
A seven-person crew consisting of project managers, engineers and cross-trained service line specialists, working 24/7 in two shifts, accomplished the total project in just under 21 days.
The short time frame was possible because of Furmanite’s capability to combine engineering, manufacturing and service line expertise through its unique cross-training program. Unparalleled in the industry, Furmanite provides continuous training and certification of service line specialists who are crossed-trained to perform multiple specialty mechanical services.
The benefit to our customers: lean efficiencies in project time, project cost and number of people needed to perform tasks. Fewer technicians required on a job site means less congestion in work spaces, less instruction and job handoff, and reduced standby time. The same crew moved seamlessly from one mechanical operation to the next shortening the time needed to complete the project.
“I want to express how proud I am of this team. Our departments worked night and day with Furmanite to design, fabricate, test, modify and finally install the big rig. This is a great example of what it looks like when teamwork and a commitment to excellence in performance come together. My thanks to all of you for your dedication and perseverance for seeing this through to its successful end.”
