Frank’s International recently helped a major operator achieve their new company record for hook load/landing string weight on an ultra-deepwater drillship in the Gulf of Mexico. Multiple Frank’s technologies and services were deployed to help make the operation a success, highlighting the company’s capabilities as a high-value, low risk solutions provider specializing in the most challenging applications.
Following Frank’s standard practice, before beginning operations, Frank’s engineering, applications, and operations groups completed a detailed technical analysis on all critical items within the load path to ensure successful installation of the heavy string. This included performing a slip crush analysis on the landing string to ensure the integrity of the tubular would be safely maintained during land out of the casing string. The results from this analysis concluded that the Frank’s 1,500 Ton Landing String Spider would be the optimal solution for the job to help minimize risk. Frank’s also analyzed the critical load path elements within the Wireless Gen II Cement Head and SKYHOOK® Cement Line Make Up Device to ensure the structural integrity of these technologies would be safely maintained during cementing operations.
During the operation, Frank’s provided surge modeling that was adjusted for real-time parameters based on results from running the string and current rheology. This resulted in zero losses while running in hole.
In total, the casing was 20,874 feet in length with a water depth of 4,520 feet and a company record-breaking final hook load of 2,402,800 pounds before land out. The Frank’s load bearing technologies that were used during the operation include the Wireless Gen II Cement Head, SKYHOOK® Cement Line Make Up Device, 1,250 Ton Drill Pipe Elevator, 1,500 Ton Landing String Spider, 100 Series Diverter, Diverter Test Device, and Large OD Isolation Valves. The combined solutions from Frank’s TRS and Cementing Technologies divisions provided a safe and efficient operation while handling the extreme load.
