HOUSTON - 2H Offshore has launched the STREAM (STeel Riser Enhanced Analytics using Measurements) joint industry project (JIP), which will see it work with operators to try to find efficiencies for the industry.
STREAM aims to provide a measurement-based foundation for steel catenary riser (SCR) modeling to allow for accurate fatigue assessment. SCRs have been widely used in the deepwater industry due to their service reliability. However, field measurements indicate that riser fatigue damage is often overpredicted 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.
Himanshu Maheshwari, 2H Offshore senior project manager, said: “Data is critical to bridge the gap between numerical analysis and actual response in the field for deepwater SCRs. The STREAM JIP will provide a platform for operators to work together to achieve an industry consensus on optimal design parameters.”
Currently, four major oil and gas operators have agreed to participate in the JIP, 2H says, and it also invites more interested industry partners to join.
