Loss Prevention
Loss Prevention
A significant aspect of operational excellence is loss prevention. Industrial Process Safety specialises in designing measures which are aimed at preventing or minimising loss from hazardous activities. The team specialises in loss prevention activities, thus enabling clients to not only avoid untoward incidents but also protect the business from them. The key loss prevention deliverables of Industrial Process Safety include:
Development of HSE Philosophies
ENVID is an essential part of the facility risk management process where environmental hazards from operational emissions and discharges to air and water as well as waste management are identified to provide input for further risk assessment and allow for design improvement. The ENVID Study takes into account direct or indirect environmental impact of facilities. Direct impacts include polluting impacts and the impacts of resource extraction under direct control of the organization, whereas indirect impacts covers matters related to supply and customer chains.
Hazardous Area Classification
The Hazard and Operability HAZOP is undertaken using a systematic and highly structured approach to examine process and engineering intentions of the design. The HAZOP Review aims to assess the potential for malfunction or mal-operation of the system/ equipment and the consequential effects of the hazardous events (impact on personnel, environment or asset), or operability problems (impacts on process efficiency or productivity) on the field development as a whole. It is based on the premise that a hazard is not realised if the process is always operated within its design intent.
Safety Integrity Level (SIL Assessments/ LOPA Assessment)
The SIL Classification Exercise is undertaken in accordance with IEC 61508 and IEC 61511 requirements employing the Layer of Protection Analysis (LOPA) approach to determine the Integrity Levels (ILs) for all identified safeguarding process loops.

Inherently Safe Design (ISD) Review
Inherently Safe Design (ISD) Review is a brainstorming exercise to address the safety issues in the hydrocarbon processing plant in order to manage, reduce, or eliminate the risk to people, environment, property, business, and process equipment.
The ISD Strategy implements five (5) elements including intensification, substitution, attenuation, limitation of impact, and simplification/error tolerance. These strategies are implemented to achieve the following:
• Hazard Elimination;
• Consequence Reduction; and
• Likelihood Reduction.
BOW-TIE
In the oil and gas industry, the bowtie approach is increasingly used to understand and communicate key risk control measures at a whole range of facilities, from an offshore oil and gas platform to a mine or manufacturing plant. Bow-Ties are a pictorial representation of the relationship between potential threats, preventive/ control barriers in place and the ultimate consequences associated with each MAH. Bow-Tie diagrams also identify potential escalation factors that could defeat or reduce the effectiveness/ reliability of a barrier, as well as control barriers in place to prevent or mitigate the effect of these escalation factors.
Matrix of permitted Operation / Simultaneous Operation Analysis / Summary of Operational Boundaries
MOPO/ SIMOPS/ SOOB are guidance tools used to define the limit of safe operations or activities that are permitted during abnormal circumstances (e.g. adverse weather, safety system offline etc.). The purpose of this review is to provide a clear presentation of the permitted operations in order to keep the facility within the defined operational envelope. It include list of typical activities that will be carried out at installation that comprise:
• Normal operations;
• Planned operations; and
• Intermittent/Abnormal operations that has potential safety impact.
It is conducted to understand how the risk of simultaneous operations or performing typical operations during abnormal circumstances (e.g. adverse weather, safety system offline etc.) could be increased, and measures or restrictions that should be implemented to manage the incremental risk such that it would still remain tolerable or As Low As Reasonably Practicable (ALARP). It provides a framework to assist personnel to decide when to continue certain activities, when the effectiveness of some critical barriers may be compromised, and potentially creating situations of increased risk. It also assists the personnel in distinguishing between a “stop work” condition and a “proceed with caution” condition.
As Low As Reasonable Practical (ALARP) Review
The ALARP Demonstration serves to review the results of all risk assessments carried out for the project to identify key risk drivers and potential risk reduction design measures. It is a brainstorming exercise to conclude upon acceptability of existing design measures and also proposing additional risk reduction measures for specific MAE. Where no conclusive decision could be reached with regards to the feasibility of certain risk reduction measures, cost benefit analysis may be performed and included in the ALARP Demonstration report (at the discretion of the workshop participants) by calculating delta PLL and quantify cost effectiveness by calculating the Incurred Cost for Averting a Fatality (ICAF).
Alarm Management
Review of alarm configuration throughout the facility with the aim to rationalised/ optimise the alarm configuration. The review identifies the purpose, importance and priority of each alarm, action to be taken on alarm failure, operator training and a robust management of change process.
