The choice of risk assessment procedure is one of the essential stages of efficient structuring of processes on prevention, localization and elimination of the consequences of accidents at main pipeline transport facilities. The authors analyzed themed publications and regulatory documents, governing procedures of risk assessment and forecasting of the consequences of possible accidents, and defined main problems in this area. Procedure for the risk assessment of accidents at main pipeline facilities was developed, the basis of which is the expert evaluation method. The procedure includes the determination of the main criteria for the assessment the probability of accident initiation and development and the evaluation of the severity of its consequences, an expert evaluation of criteria significance, their classification, and creation of a rating for hazardous pipeline sections. The application of the procedure application allows to specify the list of facilities that require high priority forecasting of accidents consequences, thus to optimize the distribution of resources and the overall increase of efficiency in planning while defining forces and special technical devices, necessary for containment and rectification of emergencies. Expert evaluation method application allows considering the specifics of certain enterprises, their technical and technological peculiarities, thereby increasing forecasting accuracy.

Risk Assessment Methodology

It is a challenge to prevent an occupational accident in any industrial activities. The aim of this study is to improve the safety and reduce the risk of occupational accidents at shipyard through developing a risk assessment. This paper describes the concept and methodology of risk assessment for occupational safety and its application. The methodology introduces an effective and useful assessment procedure to construct the database based on the past occupational accidents occurred at shipyards. Quantitative methodology is developed to understand the unsafe working conditions and environment at the shipyard by the convenient handheld to collect the data with Information Technology. Some examples of effective hazard countermeasures are suggested and a feasibility study is conducted to improve a walking environment at shipyards.

In the framework of the Risk Assessment procedure for the ecotoxicological evaluation of compounds used in the aquatic environment, tests with target species must be carried out. This paper reports the results concerning the evaluation of the acute toxicity of F-500 micelle encapsulator (Hazard Control Technologies Inc., Fayetteville, GA, USA) on cladocerans Daphnia magna, with the purpose to verify its compatibility for the aquatic environment and its adequacy for the remediation of soils polluted with hydrocarbons. The obtained results show that by adding F-500 to diesel-polluted soils, the toxicity on Daphnia magna decreases remarkably, indicating the usefulness of this compound to fight the environmental pollution consequent to hydrocarbon dumping.

Industrial Risks

In the absence of uniform and unified requirements for the assessment of industrial risks at an enterprise, the system approach remains the only tool for a comprehensive assessment of the workplace safety. Implementation of Occupational Safety and Health (OSH) system involves identifying, analyzing and reducing risks at the workplace. The purpose of the article is to calculate the minimum expenses for occupational safety measures and minimize production risks identified through the developed procedure for analyzing the hazards of the machine-building enterprise. The research methodology is based on the integrated use of qualitative and quantitative approaches to risk assessment, namely, structured assessment and integral assessment using the “rucksack problem” optimization model. The study identifies the risks that are most common and the most serious ones. The procedure of risk reduction is proposed, which is to determine the minimum costs for achieving each of the integral assessments for the machine-building enterprise. The practical value of work consists in the ability to directly apply the developed methodology for risk assessment at the enterprises of the machine-building industry, and to easily adapt the risk assessment procedure to other conditions.

In this paper, a procedure for Risk Assessment, which makes use of two risk indices (PML - Probable Maximum Loss and MFL - Maximum Foreseeable Loss) is applied to power plants to evaluate potential economic losses due to risk exposure for two different loss scenarios (probable and worst-case). The paper is mainly focused on Property Insurance aspects, though Boiler and Machinery Insurance and business interruption are also addressed. First, the procedure is applied to provide a prediction of probable and maximum loss as a function of power output. The results allow an estimate of whether the adoption of risk assessment procedures and devices allows an actual payback for plant owners. Second, the economic loss predicted through the risk assessment procedure is compared against real power plant loss values, taken from published data.

Human And Organizational Factors

ATEX (explosive atmosphere) risk assessment is required when any equipment or system could generate a potentially explosive atmosphere. Despite the fact that many operations on plants and equipment containing dangerous substances are performed by operators, influences of human and organizational factors (HOF) are mostly neglected in the ATEX risk assessment. The integrated methodology described here is proposed to address two challenges: (1) identification of the HOF influence on the ATEX risk assessment, and (2) quantification of the HOF influence. The proposed methodology enriches the traditional ATEX risk assessment procedure, which consists of four steps: (1) area classification, (2) ignition source identification, (3) damage analysis, and (4) ATEX risk evaluation. The advantages of the ATEX-HOF methodology are demonstrated through the application to a paint mixing station in an automotive manufacturing plant. The ATEX risk assessment methodologies are mainly semi-quantitative. The ATEX-HOF methodology provides a quantitative analysis for the area classification and ignition source identification, and a semi-quantitative approach for the damage analysis. As a result, the ATEX-HOF risk evaluation becomes more accurate. An event tree-based probabilistic assessment has been introduced, considering both the technical barrier failure (Prtbf) and the human intervention in terms of human error probability (HEP). The case study allowed for demonstrating how taking HOFs into account is particularly important in companies where the safety culture is lower and consequently, the usual hypothesis of the correctness of operator intervention (in maintenance, normal operations, and emergency) could bring to non-conservative results.

Fossil Power Plant

As a number of aged fossil power plants recently increased, the precise life assessment of critical equipments gets to be important more than ever. Despite of infrequent likelihood of failure, the equipments in high pressure and temperature operation condition have traditionally been considered as critical because of huge consequence of the equipments and hence life assessment of fossil power plant has been focused on all of the severe operated equipments for past decades. Nowadays, with Risk-Based Inspection technology being developed rapidly, most of the power plant utilities get a chance to reduce the scope of the inspection and test and to extend the interval for the life assessment. This paper provides methodology based on Risk-Based Inspection technology to optimize the life assessment work scope and interval and also demonstrates the enhanced life assessment procedure including risk assessment of equipments.
