IRCA has extensive expertise base in the areas of Hazard identification and Risk assessment studies are as under:

HAZID

Hazard Identification

HAZID

Hazard Identification

“HAZID” study is a multidisciplinary team oriented analytical technique that utilizes creative brainstorming to examine a process or operation. Hazard identification is a fundamental stage in a facility risk assessment. It is important that it is performed in a thorough and systematic way to ensure that as many hazards are identified as possible. HAZID (HAZard IDentification) is a technique for early identification of potential hazards and their causes. HAZID is mainly done on plot plan. The main objective of performing a HAZID is to comprehensively identify and develop credible scenarios or causes which could adversely impact safety of the facility by utilising both the experience of design, operational and safety personnel. The aim is to identify events that have a very real possibility of occurring at the facility. The Hazard Identification (HAZID) process involved the following steps:

Selection of an Area/System/Equipment in which a hazardous situation may occur;
Identification (“brainstorming”) of a top event for that hazard group;
Analysis of causes by which undesired events could occur and potential consequences;
A qualitative risk assessment of the identified hazards using a risk matrix;
Identification of the proposed control measures to prevent the accident occurring or mitigate the consequences;
Available safeguards are analyzed;
If required recommendations are made to control the hazards;
Record results, including recommendations

HAZOP Study

(Hazard & Operability)

HAZOP Study

(Hazard & Operability)

“HAZOP” study is a multi-disciplinary team oriented analytical technique that utilizes creative brainstorming to examine a process hazards and operability issue. HAZOP is a formal procedure to review design and operation of hazardous process facilities. It is used to identify deviations from normal safe operation, which could lead, to hazards or operability problems, and to define any actions necessary to deal with such deviations. The Hazard & Operability (HAZOP) process involved the following steps:

Identify a section of plant on the P&ID; referred as ‘Node’
Define the design intent and normal operation conditions of the section.
Identify a deviation from design intent or operating conditions by applying a system of guidewords.
Identify possible causes for, and consequences of, the deviation. A deviation can be considered meaningful if it has credible cause and can result in harmful consequences.
For a meaningful deviation, decide what action, if any is necessary.
Available safeguards are analyzed;
If required recommendations are made to control the hazards or operability issue;
Record results, including recommendations

SIL Classification & Verification

(Safety Instrumented Function)

SIL Classification & Verification

(Safety Instrumented Function)

A Safety Instrumented Function (SIF) is a function implemented by means of instruments and is provided to reduce the likelihood or magnitude of an accident to personnel or the facility itself in terms of asset, environmental and production loss. A SIF is designed to achieve or maintain a safe state of the process or mitigate consequences, in response to a specific upset scenario. A SIF may consist of one or more initiators (sensors, transmitters), the logic solver (trip amplifiers, safety interlocks, fail safe output), and one or more final elements (valves, motors, etc.) and utilities such as power and instrument air supply required to perform the function. The reliability of each SIF in preventing/ mitigating the hazards is reflected in the performance requirement placed upon each SIF. This performance requirement is defined in the form of a Safety Integrity Level (SIL). SIL, which is numerically defined as a Probability of Failure on Demand (PFD), indicates the degree of reliability of the function.

SIL classification: The SIL classification is to gather a SIL team to assess every safety loop. The assessment is guided by the likelihood or magnitude of an accident to personnel or the facility itself in terms of asset, environmental and production loss. When each SIL loop is classified, it is assumed that all other loops function correctly. As a result, only final element failure is considered where on initiator activates more than one function. The SIL team will discuss and agree on the health and safety, economic and environmental consequences of the loop failing to operate on demand. Each consequence will then have an assigned SIL according to the respective risks matrixes.

SIL Verification: A Safety Instrumented Function SIF may consist of one or more initiators (sensors, transmitters), the logic solver (PLC) and one or more final elements (valves, motors, etc.) and utilities such as power and instrument air supply required to perform the function. The reliability of each SIF in preventing/ mitigating the hazards is reflected in the performance requirement placed upon each SIF. This performance requirement is defined in the form of a Safety Integrity Level (SIL). SIL, which is numerically defined as a Probability of Failure on Demand (PFD), indicates the degree of reliability of the function.

SIMOPS study

(Simultaneous Operations)

SIMOPS study

(Simultaneous Operations)

The SIMOPS study is carried out through a workshop to be attended by production and Construction team members and facilitated by a competent study leader. A matrix of all production and construction is developed at the beginning of workshop session. The issues related to interfacing of the risk are then discussed through cross reference of each Construction activity with each production activity. Based upon the discussions the simultaneous operation activity is to be designated as: The issues related to interfacing of the risk are discussed through cross reference of each construction activity with each production operation activities. Based upon the discussions the activity has been designated:

Y- Permitted: Where there are no hazards or risk profile by performing the activities concurrently. It means that the two activities can be carried out following normal work procedures.

N-Not Permitted: Where the hazards introduced are considered excessive and the activities should not be conducted concurrently.

R-Restricted: Where potential hazards or risk could be elevated by the simultaneous operations and may require restrictions to be imposed or contingencies implemented. Such Restrictions are indicated as R1, R2 & so on and description of that restriction is tabulated.

QRA Study

(Quantitative Risk Assessment)

QRA Study

(Quantitative Risk Assessment)

Quantitative Risk Assessment (QRA) is a valuable tool for determining the risk from hazardous activities of facility or operation. It is quantifies risks in terms of probability and consequence and compares results with risk criteria to determine whether risk is acceptable or unacceptable. QRA is estimate risk levels and assess significance and identify main risk contributors. The risk results are presented in the following standard forms

Individual risk contours which show the geographical distribution of risk to an individual.

Group risk (FN) curves which show the cumulative frequency (F) distribution of accidents causing different numbers (N) of fatalities. The FN curve therefore indicates whether the societal risk to the facility is dominated by relatively frequent accidents causing small numbers of fatalities or low frequency accidents causing many fatalities.

FERA study

(Fire & Explosion Risk Analysis)

FERA study

(Fire & Explosion Risk Analysis)

The objective of FERA study is to calculate consequences of hydrocarbon release, fire and explosion hazards. This with reference to an impairment criteria is used to optimize the location of fire & gas detection system, fire fighting system and verifying the over pressure loads for structures and decks against the expected explosion hazards.

EERA

(Escape, Evacuation & Rescue Analysis)

EERA

(Escape, Evacuation & Rescue Analysis)

Escape, Evacuation & Rescue analysis is mostly used for offshore installations in order to evaluate the vulnerability of escape routes and Muster areas in case of a fire or explosion.

Bow Tie Analysis

This is an evaluation of Threats & barriers against a Top event. The Bow tie representation also considers Escalation factors and used to identify safety critical tasks and safety critical equipment.

PHSER

Project HSE Review is used at project stages (Conceptual; FEED, Detail engineering, Construction & commissioning & operations) to ensure that the HSE studies to be carried out at each stage have been identified, performed to the expectations of company standards and the recommendations emerging from such studies have been implemented.
