SeaPrime I海底防噴器控制系統在手 鉆進無需停工

With the current downturn, the industry is focused on finding ways to improve productivity and efficiency while reducing cost. In this long-lasting downcycle, improving BOP availability and extending the available time to drill has a significant impact on customers’ bottom lines. By focusing on reliability-driven design innovations, GE Oil & Gas is addressing some of the industry’s most complex challenges while helping drilling contractors and operators reduce downtime and drive process changes across the industry.

Improving BOP control systems

About 250 floating rigs rely on subsea MUX pods for BOP control. Due to increased complexity in subsea pods, up to 40% of BOP downtime has been attributed to faults in these systems. Downtime costs the industry billions annually, making downtime reduction a critical priority.

Industry regulations dictate the use of two MUX control pods during drilling to provide system redundancy. Should a pod fail, current industry practice is to retrieve and repair the system, causing downtime. The GE Oil & Gas SeaPrime I Subsea BOP Control System is changing this industry practice for subsea MUX controls, allowing drilling contractors to recover critical hydraulic functions without the need for a costly stack pull.

This next generation fault-tolerant architecture has the ability to reconfigure hydraulic functions subsea, preventing costly stack pulls. Hydraulic functions are isolated using an ROV for the subsea control system to reroute hydraulic functions to specific redundant sections within the same pod, all while maintaining full operations subsea. This smart redundancy element enables the system to reconfigure itself, providing three times greater system availability with only two pods.

Reliability

The SeaPrime I system has been designed from the ground up using GE’s Design for Reliability process and Reliability Availability Maintainability models, proven in other businesses, to drive system design and architecture. Advanced manufacturing solutions simplified the mechanical design of the components, while GE’s Global Research Center used advanced simulation capabilities to drive thermal efficiency and significantly improve hydraulic performance.

Maintainable ‘inside-out’ design

This new design, which has been announced as an SPE Spotlight on Technology Award winner at the 2016 OTC, simplifies maintenance and reduces service costs by improving access to electric and hydraulic functions and serviceable parts. In addition, eliminating the need to disassemble the pod to access critical functions reduces the opportunity for human error. The design also reduces potential leak points by 40% by eliminating all pilot tubing and connectors. The system offers a solution for eight-cavity 15,000-psi and 20,000-psi systems, with 20% spare functions for future growth.

Where data and controls meet

GE Oil & Gas’ SeaONYX surface control system—or the “electronic brain” that drives the subsea hydraulic controls—is powered by Mark VIe controls technology to enable robust diagnostics easily managed through an enhanced user interface. The integrated suite of controls, including both the SeaONYX surface controls and SeaPrime subsea controls, also can be paired with the SeaLytics BOP Advisor system, powered by Predix, to improve operational visibility and enable predictive condition-based maintenance. Predix, the world’s first and only cloud platform built exclusively for the oil and gas industry, is the foundation for GE’s Industrial Internet offerings. This meshing of advanced industrial technology with big data analytics gives users solutions and advanced technical products that enable condition-based repairs to minimize rig downtime
