Layer of Protection Analysis (LOPA)
Many of our customers have found Layer of Protection Analysis (LOPA) to be a cost-effective addition to PHA revalidations. Our LOPA approach is based on risk assessment fundamentals used by ABS Group personnel for over 30 years. We apply these fundamentals to help private industry and government clients make informed risk management decisions. From identifying safety barriers to determining the probability of failure to verifying safety integrity levels (SILs), our team has your needs covered.
Safety Instrumented System (SIS) Studies
ABS Group can assist process industries with confirming that the functional safety of their safety instrumented system (SIS) conforms to the requirements of ANSI/ISA-84.00.01-2004 (IEC 61511 Mod). Specifically, our personnel can assist in evaluating the need for a safety instrumented function (SIF), evaluating potential system architectures and analyzing the SIS to determine its predicted performance, from both a risk reduction and reliability standpoint. Learn how to design, specify and evaluate performance of SIFs within a safety instrumented system in our Safety Integrity Level training course or request access to our Safeguard Protection Analysis webinar.
Hazard analysis is the first and, in many ways, the most important step in a risk assessment. If a hazard is not identified, its contribution to the risk cannot be estimated. Only those hazards that are identified are likely to be controlled with any confidence. Our experts use a variety of methods such as HAZID, HAZOP, FMEA, what-if and checklists, as well as software solutions such as THESIS BowTie™ for risk management and LEADER™ for process hazard analysis, to efficiently and systematically identify workplace hazards. We also teach courses on how to identify workplace hazards, enabling employees to better understand and control the dangers in the workplace.
Safety Culture Assessment and Training
An effective safety culture is one in which people do the right thing, all the time, even when no one is watching. To drive this level of performance, factors like management beliefs, values, myths and company policies and procedures must be aligned and reinforce those values. Responding to unsafe behavior with corrective actions and activities like training and communication that build employee involvement and buy-in are powerful influences that strengthen an organization's safety culture.
ABS Group has assessed a diverse range of corporate safety cultures in a variety of facilities, including onshore and offshore operations. In these assessments, we apply a standard set of organizational attributes to measure safety culture effectiveness. We combine surveys and interviews with physical reviews of documented performance to compare perceptions with practice. Based on these findings, we can develop training programs that increase process safety knowledge and help build a sustainable safety culture at all levels of an organization.
ABS Group has numerous registrations with internationally recognized entities, governments, trade associations and professional societies. Our Safety, Risk and Compliance engineers can serve as expert witnesses, attesting to the compliance of regulatory safety requirements, best practices for maintaining safety, the quality of safety management systems, typical industrial hazards in high-performance assets, safety culture and appropriate methods for investigating an accident.
We provide a number of techniques to identify and analyze hazards, including utilizing the THESIS BowTie™ Software 6.3 standalone and THESIS™ Enterprise software solutions. These tools enable companies to manage hazards locally and across the corporation as well as demonstrate compliance clearly across all levels.
