PHA STUDIES [HAZOP, WHAT-IF]
Process Hazard Analysis (PHA) studies are the foundation for process safety and risk management programs. They help companies identify hazard scenarios for a process that could adversely affect people, property, or the environment. PHA techniques such as Hazard and Operability Studies (HAZOP), What-If Studies, Failure Modes and Effects Analysis (FMEA) are used.
A team leader, or facilitator, works with a group of people who know the process to conduct the PHA. The team leader prepares for the study, advises on the selection of team members and methodology and the definition of study scope, and oversees the team’s brainstorming of causes and consequences of possible accidents and the formulation of recommendations for appropriate corrective actions.
MicroWatt has conducted PHAs for a wide variety of facilities, and has facilitated dozens of studies using such techniques as HAZOP, What-If, MHA, FMEA, Fault Tree Analysis, etc. and we continue to develop new and improved approaches for performing and conducting PHA studies.
SIL DETERMINATION & VERIFICATION
SIL Determination is most commonly done using the Layer of Protection Analysis (LOPA) methodology. This process is a semi-quantitative methodology used for selecting SIL targets for safety instrumented functions.”
SIL Verification is the quantitative analysis to verify that the SIL target can be met with intended SIS design. SIL Verification includes determination of probability of failure on demand and spurious trip rates. SIL Verification considers the type of equipment employed, advanced voting arrangements, diagnostics, and testing frequency. MicroWatt consultants utilize the latest standards-based analysis to perform calculations in accordance with ANSI/ISA 84.00.01-2004, technical report ISA TR84.00.02, and the international standard, IEC 61511. Microwatt leverages the Kenexis Vertigo software in completing SIL verification calculations.
QUANTITATIVE RISK ANALYSIS
QRA involves the combination of accident consequences and probabilities into various risk measures including indices, individual risk, and societal risk. Results of the analyses are presented as point estimates, risk contours, or frequency-number (F-N) curves. Usually, the risk measures are compared with risk tolerance criteria such as limit lines. Risk sensitivities, importances and uncertainties are also evaluated so they can be considered in decision making.
QRA is used by companies in several ways including analyzing and ranking scenarios identified in process hazard analysis (PHA), providing quantitative data for use in decision making on risk, and comparing alternative process design options.
Increasingly, companies recognize that reliance on purely qualitative risk analysis is insufficient where high consequence, low probability accidents are concerned. Qualitative risk estimates are subjective. Quantitative analysis provides a sounder basis for decision making regarding the tolerability of the risk of catastrophic accidents. The performance of QRA requires highly skilled personnel – MicroWatt partners with industry leaders to deliver these services.
FGS PERFORMANCE TARGET SELECTION
MicroWatt uses principles on performance-based design in fire and gas system design outlined in the ISA TR84.00.07 to ensure that the system is adequately designed to meet our clients’ needs. Performance-Based design of FGS has been proven to result in a cost-effective, safe design at lower overall installed costs from equivalent systems designed using solely prescriptive based methods.
Proper design of fire and gas systems begins with the selection of a performance target for functions employed by the fire and gas system. Performance of a FGS is primarily characterized by the systems ability to detect a hazards (detector coverage) and the systems ability to mitigate hazards (mitigation effectiveness). Determination of the necessary coverage, mitigation effectiveness requirements for a FGS is an exercise in risk analysis.
MicroWatt is a world leader in the development of risk based techniques for determination of performance targets for safety critical systems such as FGS. Our consulting staff have backgrounds in process, control systems, and instrumentation engineering, all of which are critical disciplines for engineering a high-quality fire and gas system.
Complying with safety, quality and environmental regulations and standards is increasingly important and has become more difficult as operations grow. Individual facilities are frequently using different methods and descriptions to define and assess risks, different models to score the severity and likelihood of risk and a multitude of systems and methods to control operational risk. This creates isolated pockets of risk knowledge, and impedes the ability to accurately share best practices and lessons learned while effectively managing risk across the business. MicroWatt enables you to standardize your process for identifying, analyzing, mitigating and monitoring operational risk. We provide a means to quickly and accurately understand your risk profile, helping you make better decisions and drive sustainable improvements.
FGS SYSTEM PERFORMANCE VERIFICATION
Fire and Gas Detection and Mitigation Systems are key components in the overall safety and operation of any production facility and its on-site personnel. However, in many instances the overall importance of these systems has not been fully comprehended. In many cases they have been implemented using the DCS (Distributed Control System), or a COTS PLC (Commercial-Off-The-Shelf Programmable Logic Controller), with too few detectors and alarm devices, and without clearly defined performance goals. Alternatively it is also quite common to see too many detectors in engineering designs which has huge up-front and on-going lifecycle costs which easily cover the cost of the studies. Both scenarios are partly due to the fact that historically Process Safety Standards did not include F&G Detection and Mitigation Systems.
The performance-based requirements for F&G Systems are not unlike those employed in the design of ESD Systems. Performance-based Standards typically require diagnostic coverage, redundancy, etc. and verification to ensure that the actual performance of the Safety Instrumented Functions (SIFs) meet their specified SILs. However, this is a departure from past experience, where prescriptive design was used and system performance was usually assumed to be sufficient. While these techniques have proven adequate for buildings, living accommodations, etc., they do not address the F&G Detection and Mitigation requirement of process facilities, the safety of which are comprehended in the IEC 61511 Standard and the basis for ISA TR 84.00.01 Standard, designed for the process sector.

COST REDUCTION STRATEGIES
Development and production costs have more than doubled in the past 10 years and managing resources efficiently has become an ever-greater priority—especially since oil prices are likely to remain depressed for the foreseeable future. Traditionally, companies have responded to low oil prices, high costs and weak margins by cancelling or postponing projects, laying off staff and freezing spending. But, reactive short-term actions such as these, risk destroying value. Facilities maintenance, for example, often falls victim to short-term cost reductions. While slashing maintenance budgets might deliver savings in the short term, postponing maintenance will eventually undermine longer-term asset integrity, and give rise to reliability and HSE issues. In fact, many of the E&P industry’s major accidents have occurred during periods characterized by extreme cost-cutting measures.
MicroWatt believes that cost management should not be viewed as a one-time initiative to be undertaken in reaction to adverse economic conditions. Indeed, transformational changes to the existing approach to cost management have become essential: the industry must change how it identifies the causes of inefficiencies and manages costs, and must learn to do more with less. Leverage MicroWatt’s 30 years of experience working with dozens of end-users in hundreds of locations to optimize their safeguarding and lower the maintenance associated with these systems.
