DESIGN FOR SAFETY, SECURITY & RELIABILITY

KENEXIS

Kenexis provides services and software focused on reliability engineering in all its forms to assist organizations make their operations safe, secure and reliable. We provide reliability engineering services for Safety Instrumented System (SIS), Fire and Gas Detector Mapping, and Industrial Control System Cybersecurity. Our services and software focus on reliability engineering in all its forms to assist organizations make their operations safe, secure and reliable.

Our reliability engineering services are defined by ISA84/IEC61511 and include expert PHA facilitators to develop your Hazard and Operability Study (HAZOP) to determine process scenarios that may require additional protection, SIL selection using Layer of Protection Analysis (LOPA) to establish requirements for each SIF for every process scenario of concern identified in the HAZOP.  We will roll all this up into the SRS for the configuration of SIS, its test planning and continuing performance assessments and auditing including reevaluation of the SRS after change.

Additionally, our state-of-the-art Fire and Gas mapping (FGS) utilizes performance-based design concepts defined in industry norm ISA84.  We provide both geographical coverage and scenario-based coverage against performance targets, which are usually selected at the beginning of the project, typically based on an analysis of the specific process hazard(s).

Our Industrial Control System Cybersecurity services are based on ISA/IEC-62443 include practical secure design and migration planning, vulnerability assessments, penetration testing, incident response, and policy and procedure development. Our ICS cybersecurity services also follow reliability engineering principles.

We also provide engineering software designed to improve the task of reliability engineering whether you are calculating λ or IPF SIL level, performing fault-tree analysis, or trying to meet the performance target with your gas detector array.

Our services and software are designed to assist our clients with compliance and to benchmark their performance against industry best practices. Kenexis believes in its process and follows strict quality control standards as an ISO 9001 Certified organization.

We actively participate and contribute to industry standards and best practices. These include ISA84/IEC61511 Safety Instrumented Systems (SIS) used in the Process Industries, ISA/IEC-62443 (formerly ISA-99) Industrial Automation and Control Systems Security.
