Consulting Engineering Services focused on the safe operation of processes in oil & gas, chemical, and other industries. Our engineering services focus on four main areas, Safety Instrumented System (SIS), Process Hazards Analysis, Fire and Gas Detector Mapping, and Industrial Control System Cybersecurity.

Our services are defined by ISA/IEC 61511 and ISA/IEC 62443 in addition to standards and best practices from all corners of the globe.

Our team includes 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 also develop complete Safety Requirement Specifications (SRS) for the configuration of SIS, test planning, and continuing performance assessments and auditing including reevaluation of the SRS after change.

Our Fire and Gas Mapping team utilizes performance-based design concepts defined in the ISA 61511 Standard.  Our fire and gas design basis utilize both geographical coverage and scenario-based coverage against your performance targets using various scenario analysis methods including sub-sonic and super-sonic gaussian and computational fluid dynamics.

Our Industrial (OT) Cybersecurity services follow NIST Cybersecurity Framework for appropriate standards in specific areas like the ISA/IEC 62443 Standard for the industrial control system environment as well as NERC CIP, NIST SP800, and ISO/IEC 27001. We also follow appropriate standards for the local areas where a standard has been established. Our services include industrial control system focused vulnerability assessment, penetration testing, network design and migration planning, policy and procedure development, conformance and gap analysis, and critical layer of protection analysis using Security PHA Review methods .

Kenexis engineering software is designed and built by process safety engineers to improve 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 also follows strict quality control standards as an ISO 9001 Certified organization.
