Transcription

1 Safety Innovations for Oil & Gas Siemens innovative approach to functional safety helps meet the requirements of the oil and gas industry by maximizing safety while also ensuring high availability and reduced costs

2 Process safety, layers of protection, functional safety Plant and Emergency Response Emergency response layer Mitigate Containment, Dike, Vessel Passive protection layer Fire and Gas System Active protection layer Incident Prevent Emergency Shutdown System Emergency Shutdown Safety layer SIS Operator Intervention Process alarm Operator Intervention Process control layer BPCS Normal Process control layer Process Value behavior

3 The Basic Process Control System (BPCS) & Safety...

4 Increased operator efficiency through task-oriented organization of process displays Topology Level 1 Plant / process Orientation navigation Overview display Performance/ availability Topology-oriented and task-oriented plant hierarchy (level 1 - level 3) Level 2 Plant area Monitoring & control Control display Key process values (normal operation) Significance of level 2, more displays, mainly used for monitoring but also for controlling Level 3 Plant section Level 4 Functional aspects Diagnostics (control) Detail display Support display P&I oriented e.g. group control Several detailed views on the same plant section, mainly used temporarily for start-up, diagnostics etc.

5 Information-based visualization in SIMATIC PCS7 SIMATIC PCS 7 visualization to support operators 1 Hybrid displays 2 3 Trend display with bar graph Spider diagram to display KPI Graphic objects support situational awareness and decision-making Gradient display Temperature profile of distillation column

6 Alarm management Effective alarm management with SIMATIC PCS 7 alarm system ISA 18.2 Alarm processing and filtering Smart alarm hiding Prioritized alarms depending on urgency Alarm-related help texts Operator guidance (loop-in alarm) Process oriented representation of alarms EEMUA 191 IEC Priority Alarm management design supports operators when handling abnormal situations

7 Safety integrated for process automation The fully integrated safety solution Integrated control & safety capability + Safety lifecycle tools for engineering and operation cause & effects matrix + Integrated EX-IO for Zone 1 + Flexible Modular Redundancy (FMR) Flexible, scalable, high available + SIL capable instruments + Integrated safety fieldbus technology PROFIBUS and PROFINET +

8 Flexible Modular Redundancy Flexible Redundancy at all levels Scalable for different applications (ESD, HIPPS, F&G etc.) Controller redundancy for availability.. not required for safety Physical separation to combat common cause Flexibility to accommodate different SIF architectures so Field device redundancy can be designed to achieve safety and availability goals I/O redundancy independent of CPU

10 Features and benefits of integrated control & safety Enterprise Level Field Level Common Operator Interface Benefits Single Window Consolidated Alarms, SOE Integrated Reduced Asset cost Management Easier to maintain Common Engineering For Automation, Instrumentation, Drives, Easier Visualisation to change Safety Lifecycle Tools Reduced spares holdings Common Hardware Reduced training Integrated or Common as required Improved operability & safety Standard & Safety I/O in same rack Reduced project risk Standard & Safety Communication on the same networks

11 Design & engineering performance Integrated safety lifecycle tools SIMATIC Safety Matrix

12 Design & engineering performance Integrated safety lifecycle tools

13 Design & engineering performance Integrated safety lifecycle tools The realization phase The SIMATIC Safety Matrix as engineering tool Configuration of the safety functions using the Cause & Effects method Automatic TÜV-certified creation of the Safety Logic from the Cause & Effect matrix Easy configuration without special programming knowledge Online monitoring mode for verification and validation Reduces systematic errors Simplifies engineering, verification and validation Saves time, improves safety

14 Design & engineering performance Integrated safety lifecycle tools Operation & maintenance, modification Online view of the signal status, Cause & Effects Automatic integration in PCS 7 First up alarm display and storage Supports operator bypass, reset, override and parameter changes Sequence of event recording Automatic report of operation functions Automatic version tracking Automatic documentation of changes Reduces systematic errors Simplifies engineering, verification and validation Improves operator efficiency Saves time, improves safety

15 Decentralized automation for the hazardous area SIMATIC ET 200iSP Failsafe modules for SIMATIC ET 200iSP Features 3 failsafe modules to install directly in Ex-zone 1/21; up to SIL 3, PLe Digital Input Module F-DI8 NAMUR Digital Output Module F DO4, 17,4V DC 40mA Analogue Input Module F-AI4 HART Customer benefits: Reduced installation effort by using ET 200iSP compared to traditional solutions (with Ex barriers) Line monitoring up to sensors SIL calculation advantages (no Ex barriers) Complete portfolio - failsafe protection in Ex-Zone 1 especially for applications like ESD (Emergency Shut Down), boiler protection (e.g. at biogas plants), fire-extinguishing system or gas / fire detection

16 Selected instruments pressure, temperature, level, Valve positioners, analysers

17 Safety integrated for process automation The fully integrated safety solution Your benefits using safety integrated for process automation from Siemens One partner for control & safety. Diagnostics and visualization of safety are directly integrated into the DCS. Employees can be trained on one system for control & safety. They are able to maintain both systems. Reduce your personnel costs. A fully integrated system forms the basis for consistent engineering and predictive maintenance. Minimize your downtimes and maximize your profit. Keep the process running with integration.
