Safety Instrumented Systems (SIS)

ENGlobal’s Automation segment offers their clients experienced, in-house resources to manage process safety projects using a lifecycle approach necessary to achieve compliance to current industry standards.  These services are based upon proven methodologies for addressing the design, operation, maintenance, testing and change management associated with safety instrumented systems (SIS) as defined by the current industry standards ANSI/IEC 61511 and ISA 84. 
 
The selection of the safety lifecycle upon which the project is executed is based largely on each client’s unique circumstances and preference. ENGlobal has industry certified engineers (CSFE / TÜV FSEng) available to provide leadership, facilitation and engineering services associated with:
  • Process Hazard Assessment (PHA)
  • Hazard and Risk Analysis including Safety Integrity Level (SIL) Determination
  • Allocation of Safety Functions to Independent Protection Layers (IPL)
  • Safety Requirements Specification (SRS)
  • Conceptual Design including Cause and Effects
  • System Integrity Level (SIL) Calculations and Verification
  • Software Detailed Engineering
  • Factory and Site Acceptance Testing (FAT/SAT)
  • Field Equipment Purchasing and Installation
  • Field Junction Boxes, Wiring and Marshalling
  • Proof-Test Procedures
  • Change Management
ENGlobal provides their clients with a unique service offering that leverages their process safety management and advanced automation resources with their in-house process engineering capabilities. Typical SIS vendors lack the process knowledge, while most process design firms do not possess the extensive automation expertise required to deliver these critical services.  ENGlobal is a single-source supplier for not only SIS engineering, but piping and process modifications, instrument installation, and overall construction management.
 
ENGlobal realizes that there may be projects which require additional resources not immediately available. For this reason, ENGlobal has existing relationships with companies who can assist in facilitating PHA’s and LOPA’s, as well as offering external reviews and audits of ENGlobal’s work processes and project documentation. This allows ENGlobal to mobilize a world-class team with unmatched capabilities.
 
ENGlobal has specialized resources necessary to provide their clients with consultancy services addressing new and emerging technologies like PROFIsafe and FF-SIS fieldbuses. ENGlobal has proven experience working closely with all leading suppliers of logic solvers, including:
  • Honeywell (Fail Safe Controller / Safety Manager)
  • Invensys/Triconex (Tricon)
  • Rockwell/ICS (Triplex)
  • Siemens (SIMATIC), and
  • Yokogawa (ProSafe)
Project references include many of the largest oil and gas companies covering onshore refineries and chemical complexes, as well as offshore production platforms. Many of these projects included fabrication of control cabinets, instrument buildings, site construction, equipment installation, and cutover. This provides ENGlobal’s clients with a single point of responsibility for complete engineering, procurement, and construction services associated with their safety instrument system projects.
