2H Offshore is seeking additional participants for its recently launched STREAM (Steel Riser Enhanced Analytics using Measurements) joint industry project (JIP).
So far, four major oil and gas operators have agreed to participate in the JIP. The JIP’s goal is to provide a measurement-based foundation for steel catenary riser (SCR) modelling to allow for accurate fatigue assessment, says 2H Offshore. 2H Offshore are riser and conductor specialists in the subsea services group Acteon.
Because of their service reliability, SCRs have been widely used in deepwater oil and gas. However, field measurements indicate that riser fatigue damage is often over predicted at the critical touchdown region, which can lead to higher riser costs for the industry.
Full-scale field data from six deepwater SCR systems has been secured from STREAM JIP participants. 2H will apply its proven riser response data analytics methodology to benchmark design, identify gaps and derive calibrated modeling parameters. The results will benefit the future design and life extension of riser systems.
“The modern subsea market is evolving, with a need for smarter, more efficient solutions,” says Himanshu Maheshwari, 2H Offshore senior project manager. “At 2H we are leading these changes by combining our domain expertise with the intelligent use of data.
“Data is critical to bridge the gap between numerical analysis and actual response in the field for deep water SCRs,” Maheshwari adds. “The STREAM JIP will provide a platform for operators to work together to achieve an industry consensus on optimal design parameters.”
