Oil Patch Bits: PCT completes extreme lifting project for BP
Peak Civil Technologies, a division of Peak Oilfield Service Co., said April 9 that it recently completed a concrete floor lift using structural polyurethane. This in itself is not news, since the process has been in use on Alaska’s North Slope since 2002. However, lifting 5-foot thick concrete which has settled and bringing it back to level with this process had previously never been done. BP authorized PCT to re-level their Vibration Shop floor for work to begin in February 2010. The concrete floor to be lifted was a nominal 8 inches, yet had a crane pedestal which was designed to a thickness of 5-foot reinforced concrete. Complicating matters further, a 20-ton crane sat on the pedestal adding extreme weight to the lift. Having lifted concrete exceeding 3 feet in thickness in the past, the PCT crew was confident the lift and realignment would be successful. The hardest part was drilling through the 5-foot-thick monolith without hitting reinforcement steel. PCT provides floor and foundation re-leveling work throughout Alaska, along with other unique civil applications. For more information visit www.peakalaska.com.
