FSES provides a variety of services to a vast industry base, see below:

Global providers of Functional Safety Consultancy and Engineering Safety Consultancy Services.

Functional Safety Consultancy Services

Compliance to the international Standards such as IEC 61508 and IEC 61511 are imperative to meeting the Functional Safety requirements for many processes and have formed part of the quality management systems of many companies. Provision of Functional Safety Services in line with the Phases and Activities detailed in the Safety Life-cycle is an area in which our consultants have demonstrate a vast experience and expertise.

Functional Safety services can be categorised into 3 main areas:

  • Management of Functional Safety for control and minimisation of systematic errors.
  • Reliability Assessment in terms of Random Hardware Failures.
  • Architectural Assessment and requirements for Hardware Fault Tolerance.

Input of expert consultancy services in Front End Engineering or Detailed Design stages are key in achieving Functional Safety. Support in procurement, design and implementation of Safety Instrumented Systems are imperative in meeting the safety requirements of a project. Functional Safety Consultancy can support you on all your functional safety requirements.

The following is an extraction from IEC 61508, which represents the simplified Safety Life Cycle.

Technical & Engineering Safety Consultancy Services

Alarm Management, Flow assurance, Plan optimisation, RAMS and RCM are just a few of the Engineering Safety Consultancy services we specialise in for the process sector. Globally we are approached at various stages of engineering design to support the various goals and requirements of projects.

Over the years we have grown quite a reputation in provision of high quality engineering consultancy services which is supported by our extensive list of clients.

FSES Technical Safety Services

Whether your needs are for Functional Safety or Safety Engineering Services don’t hesitate to drop us an email or give us a call. See below with regards to contacting us or visit Contact Us.

PHA, HAZID and HAZOP Studies

FSES can provide Process Hazard Analysis (PHA) and HAZard and OPerability (HAZOP) study chairpersons. Our expert PHA facilitators hold certification in conducing HAZOP, HAZAN and CHAZOP.

Functional Safety Training

FSES provide various Functional Training services for all of specific parts of IEC 61508 and its sector derivatives.

Consequence Modelling

Discharge and Dispersion is often required to evaluate the consequence of identified hazardous events.

Design Engineering

Functional safety activities are most effective by integration into a well-established and proven quality management system.

Building Risk Assessment

Building Risk Assessment (BRA) is a tool used to assess the risks to people in occupied buildings in the facility.

Human Factors

Human factor assessment is a key area in identifying potential hazards which may be instigated by human errors.

Proof Testing Procedures

Proof Testing is one of the main requirements to ensure that Functional Safety is maintained throughout the operational phase.

Operation and Maintenance

FSES can carry out review studies and provide consultancy to ensure Functional Safety requirements are maintained during Operation and Maintenance.

Process Hazard Assessment (PHA)

FSES can provide Process Hazard Analysis (PHA) and HAZard and OPerability (HAZOP) study chairpersons. Our expert PHA facilitators hold certification in conducing HAZOP, HAZAN and CHAZOP.

Safety Requirements Specification

The Safety Requirements Specification (SRS) is a core document, which is used as the main reference to be followed by designers, installers, and operators of a Safety Instrumented Function (SIF).

SIL Determination

FSES are able to us various methods in identifying SIL targets; qualitatively by Risk Graphs, semi-quantitatively by Layers of Protection Analysis (LOPA) or fully quantitatively by Fault Tree Analysis (FTA).

SIL Verification

Calculation of Random Hardware Reliability and Architectural Assessments for Safety Instrumented Functions (SIFs).
