Pipe Plugging Solutions: Thank you for the training I received on Inflatable Bags. It has been both rewarding and a pleasure working with you since our first meeting at the Offshore Technology Conference in May of 1999. The successes we both have had in designing and building equipment to meet the special requirements of our customers has been very rewarding. I appreciate everything you have done to make this possible. I have very high regard for your analytical and problem solving ability in achieving an objective and creating solutions to problems.

Tom Bowling, Team Industrial Services Just to let you know we have completed the work in Bangladesh using the Petersen Plug and it was a great success. Whenever we need or hear of anyone doing this kind of work we will gladly recommend Petersen.

Cameco Cigar Lake Uranium Mine is the largest uranium mine in the world. Flooding via a fissure occurred in August 2008 at the 420-meter level and completely stopped work. To stop the flooding, Cameco had to create a barrier in that level that would completely seal off the area of inflow. Cameco Project Engineer Brian Dixon, decided to use an inflatable tunnel seal (ITS) from Petersen Products Company. The ITS, which is a cylindrical plug designed to expand to approximately seven meters when inflated, had to be positioned and oriented precisely by an ROV, and then filled from the surface not once, but twice: once with water to check position, and then with a custom formulated grout to form a permanent seal. In October 2009, after all grout was set, Cameco reported that the water inflow had “been remediated,” and in February 2010, dewatering crews reentered the working level of the mine, 480 meters (1,575 feet) beneath the surface and 60 meters (197 feet) below the previously flooded 420m level.

Duke Power needed to plug a 42-inch line located 12 feet under the basement of a nuclear power plant. The piping for fuel, chemical transport, water supply, and cooling needs is typically very complex and subject to high temperatures and pressures.

Shutting down entire lines is not practical as realities dictate that plants must be kept running more or less continuously.

Downtime is simply unacceptable so it is necessary to plug a pressurized pipeline. Plugging the nuclear power plant line went smoothly and the Petersen Plug was kept in place for a week before being removed.

Southern Louisiana Refinery had two banks of exchangers operating, but one was contaminated by leaking gas. To fix the leak and keep at least one exchanger bank working, they would have to plug a 16 inch inlet under 180 psi, with temperatures up to 230ºF. A Petersen® Inflatable Line Stop Plug “bag” was inflated with diesel fuel, “that way, if there was a leak, there wouldn’t be contamination. The bag was in for six months and didn’t fail.”

Grace-Titan 60” Water Pipeline: When Brian Simon, a project manager at Grace-Titan DVBE (based in Redding, CA) first looked at the Potter Valley By-pass job it looked difficult. GraceTitan was being asked to remove a section of the 100-year-old five-foot diameter penstock that supplies Pacific Gas & Electric’s (PGE) Potter Valley hydroelectric plant and install a Y-branch.

Grace-Titan was told to expect flow leakage as high as 1,200 gpm.

A physical block was needed and an existing 18-inch manway presented the best opportunity. “We hadn’t done anything like this before, so we did some research,” says Simon, “and it seemed like an inflatable plug was the way to go.”

Inflatable Line Stops

Petersen Products fabricated a plug that could be folded for insertion through the manway, then inflated with water to fill and block the penstock. “We opened up the manway and inserted the plug. Once in place, the plug was tethered with dual aircraft cables. The plug sealed well, and held for the entire seven weeks of the project.”
