CS7X Electro-Hydraulic Safety Shutdown System Overview

eP's CS7X™ electro-hydraulic safety shutdown system is a low power, highly reliable, microprocessor based, integrated wellhead control system. By providing operation of wellheads and other production functions using standard “application modules” the system achieves a high level of safety and control.

The CS7X system is optimized for controlling offshore platforms. The low power requirements are ideal for production applications where conventional power sources are not available. The integrated hydraulic/pneumatic logic provides quick dedicated safety monitoring. SCADA systems easily link with the system to allow for remote monitoring and control.

Each electro-hydraulic safety shutdown system is assembled and tested to the latest CENELEC standards for use in hazardous areas.

CS7X Electro-Hydraulic Safety Shutdown System Interfaces

The CS7X electro-hydraulic safety shutdown system is a communication center at the well site. The system allows for multiple SCADA applications to access data from the RTU as well as a number of slave devices. SCADA applications can access the system via TCP/IP, RS485, and RS232 links. The CS7X RTU can use these same links to scan and control many slave devices. SCADA applications can access any data in the slave devices utilizing the RTU’s “pass-through” capabilities.

Typical SCADA Operations for the CS7X Electro-Hydraulic Safety Shutdown System

• Monitor safety valve and surface equipment statuses
• Adjust chokes to maintain production
• Open/close safety valves
• Issue remote shut-in of the platform

In conjunction with SCADA support the RTU has embedded TCP/IP access. The web server can access HTML or Flash programs residing on the RTU. The database can be accessed via Telnet or eP’s Phoebus Explorer™ configuration program. The 40 channels of logged data points can be downloaded automatically via the RTU’s FTP access.

CS7X Electro-Hydraulic Safety Shutdown System Scalability

The CS7X electro-hydraulic safety shutdown system can be scaled for your company’s requirements. From single level to a multi-level system with up to four distributed control modules. At each level of the system, RTU redundancy is an option. With the ability to add hundreds of I/O, complete platforms can be monitored and controlled from one central location.

The multi-level solution is designed to allow for individual wells to be controlled closely by a dedicated RTU while still being part of a complete control package. The master control module (MCM) is at the top level and interacts with each of the slot control modules (SLOM). The MCM handles emergency shutdown (ESD) commands and interacts with the SCADA host and other shared resources. The SLOM controls a single or a group of wells while communicating status back to the MCM.

I/O controls modules are added to meet the requirements of each system. Individual analog input, analog output, digital input, and digital output modules supply the interface with the platform’s instruments.
