Opis:
The Haddon matrix is a potential tool for recognizing hazards in any operating engineering system. This paper presents a case study of operational hazards at a large construction site. The fish bone structure helps to visualize and relate the chain of events, which led to the failure of the system. The two-tier Haddon matrix approach helps to analyze the problem and subsequently prescribes preventive steps. The cybernetic approach has been undertaken to establish the relationship among event variables and to identify the ones with most potential. Those event variables in this case study, based on the cybernetic concepts like control responsiveness and controllability salience, are (a) uncontrolled swing of sheet contributing to energy, (b) slippage of sheet from anchor, (c) restricted longitudinal and transverse swing or rotation about the suspension, (d) guilt or uncertainty of the crane driver, (e) safe working practices and environment.

Opis:
This paper deals with the phase-shift fault analysis of stream cipher Grain v1. We assume that the attacker is able to desynchronize the linear and nonlinear registers of the cipher during the keystream generation phase by either forcing one of the registers to clock one more time, while the other register is not clocked, or by preventing one of the registers from clocking, while the other register is clocked. Using this technique, we are able to obtain the full inner state of the cipher in reasonable time (under 12 hours on a single PC) by using 150 bits of unfaulted keystream, 600 bits of faulted keystreams and by correctly guessing 28 bits of the linear register.

Opis:
The Solokha gas field is one of the most valuable hydrocarbon fields in the central axial part of the Dnieper-Donets Basin (DDB). Every new exploration well there has to be highly validated in order to reduce possible drilling risks. In this study, the characteristics of faults, as possible seals, are analysed, based on the latest well and 3D seismic data. Evaluating fault seal risk is a constitutive factor in hydrocarbon exploration and production. For this reason, to reduce uncertainty in the faults’ leaking facilities, we used a couple of known approaches, such as juxtaposition analysis, with building Allan diagrams, to determine the relationship between sand-sand juxtaposition and the occurrence of hydrocarbons-bearing sands. We used the Shale Gouge Ratio (SGR) calculation with prediction of clay content distribution along the faults, pressure data analysis, seismic at tributes modelling and self-organized map clustering analysis for accurate delineation of sand bodies shape. This represents a complex research method of integration of high-quality depth processing with seismic structural and stratigraphic interpretation and, also, geological modeling. In this paper, we assessed the Jurassic and Visean faults of the Solokha gas field, according to their fluid cross-flow facilities. This research will provide valuable information about the presence of prospective places for hydrocarbon accumulation and will likely impact the well staking process for the upcoming drilling.

Opis:
The development of fault pattern in the Silesian Nappe (Central Carpathian Depression) in the eastern part of Polish Outer Carpathians is outlined, from field observations and interpretation of air photos and radar images. Fault slip analysis and palaeostress reconstruction was applied to determine different systems of strike-slip, reverse and normal faults and the relative age of each system was determined. The results show a consistent evolution of fault systems which occurred as several episodes. Some of these episodes are local but others represent a regional pattern of faulting across the whole Polish Eastern Outer Carpathians. The beginning of fault evolution took place in Late Oligocene to Late Miocene times. The oldest phase is represented by reverse and thrust faults of system R1 with SW-NE compression; a younger phase involves origination of strike-slip faults belonging to system S1 (with the same direction of compression). Reverse (system R2) and strike-slip (system S2) faults were formed locally during a N-S compressional event. Dextral strike-slip faults of system S3 with simultanous opening of a dextral set of fault system S1 originated subsequently. The youngest events are represented by normal faults N1, N2, and N3 systems during NW-SE, and SW-NE to N-S extension.

Opis:
Technological progress, as well as the development of the sciences on occupational health and safety, increased safety and improved working conditions in enterprises of even the most onerous industries. To maintain the required level of safety, preventive actions are taken to identify all hazards in the workplace. In practice, many methods are used to identify hazards depending on the type of technological processes and the types of workstations analyzed. The article presents the advantages of the fault tree analysis method as a tool to support the process safety management in the enterprise. The article presents features of the fault tree analysis method as a tool for better security management in an enterprise. Cause and effect relationships between events in the fault tree schema on selected examples were examined. Indirect and direct causes of accidents and failures in the enterprise have been identified, including human errors (human factor). The use of the fault tree analysis method to support accident and failure risk assessment in an industrial plant was also analyzed.

Opis:
Many lives and aircrafts have been lost due to human errors associated with mental workload overload (MWLOL). Human errors are successfully considered in existing Fault Tree Analysis (FTA) methods. However, MWLOL is considered through Performance Shaping Factors indirectly and its information is hidden in FT construction, which is not conducive to analyze the root causes of human errors and risks. To overcome this difficulty, we develop a risk analysis method where Multiple Resources Model (MRM) is incorporated into FTA methods. MRM analyzes mental workload by estimating the resources used during performing concurrent tasks, probably including abnormal situation handling tasks introduced by basic events in FT. Such basic events may cause MWLOL and then trigger corresponding human error events. A MWLOL gate is proposed to describe MWLOL explicitly and add these new relationships to traditional FT. This new method extends previous FTA methods and provides a more in-depth risk analysis. An accident, a helicopter crash in Maryland, is analyzed by the proposed method.

Opis:
Due to the unique geographic location, complex navigation environment and intense vessel traffic, a considerable number of maritime accidents occurred in estuarine waters during recent years which caused serious loss of life, property and environmental contamination. Based on the historical data of maritime accidents from 2003 to 2012, which is collected from Shenzhen Maritime Safety Administration, this paper conducted a risk analysis of maritime accidents by applying Bayesian network and fault tree analysis. First a Bayesian network model was introduced to describe the consequence of accidents based on the accident investigation report. Then fault tree analysis was applied to estimate the probability on the basis of accident statistics and ship traffic flow. Finally the risk of maritime accidents in Shenzhen Waters was depicted through the consequence multiplied by the probability of an accident.

Opis:
W artykule przedstawiono analizę zagrożeń metodą drzewa błędów (FTA) dla wybranych stanowisk pracy. Zawarte w artykule schematy drzewa błędów ilustrują dwa typy zagrożeń: wypadkiem podczas pracy z prasą hydrauliczną oraz zniszczeniem maszyny na skutek przegrzania. W obu przypadkach przeprowadzona analiza wskazuje przyczyny zagrożenia wynikające z faktu awaryjności elementów maszyny lub stanowiska pracy oraz możliwe do popełnienia błędy operatora. Za pomocą drzewa błędów wskazano wzajemne związki między zdarzeniami prowadzącymi do zagrożenia w analizowanych przykładach. Zidentyfikowano również działania korygujące dla analizowanych zagrożeń w celu zminimalizowania ryzyka zawodowego.
The paper presents an analysis of the Fault Tree Analysis (FTA) approach for selected workplaces. The fault tree diagrams included in this article illustrate two types of hazards: an accident when working with a hydraulic press and damage to a machine due to overheating. In both cases, the analysis indicates the cause of the hazard resulting from the failure of the machine or workpiece, and the operator's possible errors. The fault tree identifies the relationship between events leading to a threat in the analyzed examples. The corrective actions were also identified for the hazard analyzed to minimize occupational risk.
