High Capacity Foundations
Foundation for factory acceptance testing of riser retrieval equipment for a floating production unit in the Gulf of Mexico
Oil States Industries contracted with Roger McChargue Construction (RMC) to design and build a pile-supported reinforced concrete foundation with a skid rail system that simulates the actual skid rail system installed on the deck of the Jack/St. Malo FPU in the Gulf of Mexico. RMC provided all engineering and construction services including the geotechnical investigation of the site and a finite element analysis of the foundation’s ability to resist the extreme loads imparted to the skid rail system during testing.
“We were so pleased with the experience of working with Roger McChargue Construction, and the start to finish services he and his staff provided, that for the past 15 years he has been our exclusive design and construction provider for all upgrades to our facility.” ~ Robert Nelson, Vice President & General Manager, Oil States Industries
High Load Foundation and Crane Building
Port Fourchon, LA
Roger McChargue Construction (RMC) provided all engineering and construction services including a geotechnical investigation of the site to obtaining the certificate of occupancy. RMC was awarded the Best Industrial Project in the state of Louisiana by the American Concrete Institute in 2007 for this project. The pile-supported post-tensioned reinforced concrete foundation is designed to handle (2) 35 ton forklifts carrying (1) 75,000 lb. section of riser. The 33,000 sf pre-engineered steel building is fully galvanized, totally insulated, and code compliant with the extreme wind loads that can occur on the Gulf Coast. The building is designed to accommodate multiple bridge cranes ranging from 25 to 50 tons. RMC designed and installed a 2,000 amp, 480 volt, 3 phase electrical system and lighting. The project was engineered and completed within 6 months.
Pedestal Crane Test Stand
Oil States Industries hired Roger McChargue Construction to manage the construction of the test stand for their next generation offshore pedestal cranes. These next generation cranes have booms 200 ft long and must handle a 25 ton load at any point on the compass. The foundation was designed with (16) 115 ft long heavy steel H-piling anchoring a one million pound reinforced concrete foundation.
