Commercial fisheries losses arising from interactions with offshore pipelines and other oil and gas infrastructure and activities

Abstract Interactions between fishing vessels and oil and gas infrastructure can result in damage to fishing gear, loss of fishing time/access, and risks to crew health and safety. The spatial and temporal patterns characterizing previous incidents (and subsequent losses) between fishers and oil and gas infrastructure were quantified and used to identify key risk factors associated with fisheries losses. Between the years 1989 and 2016, 1590 incidents that resulted in a financial loss, vessel abandonment, or an injury/fatality for UK commercial fishers were recorded. The annual number of recorded incidents decreased by 98.6% over a 27-year period. The majority of past incidences resulted in financial losses (rather than injuries or fatalities) and were associated with interactions between single otter trawlers and oil and gas production-related debris. The odds of an incidence occurring varied according to substrate type and fishing intensity. A risk-model for pipeline–fishing interactions in the Fladen Ground showed that there was significant spatial heterogeneity in the risk of an incident along a pipeline according to the angle and intensity of fishing. The results highlight the need to include the full spectrum of potential losses in fisheries impact assessments associated with the installation and decommissioning of oil and gas assets.

Oil And Gas Production

It is necessary to carry out work to analyze the harmful factors of accidents during the production, operation and transportation of raw materials in oil and gas fields and assess their compliance with the requirements of the standards of the Republic of Kazakhstan. The main goal of labor protection is to create safe working conditions for employees, as well as to prevent personnel from illnesses. In this regard, it is necessary to have a system of accounting, analysis and assessment of the state of labor protection, as well as management of labor protection. This article proposes ways to quickly assess the state of health and safety at work by calculating a number of occupational risk indicators based on information available in the modules for assessing occupational safety by industrial risk indicators. The efficiency of using the OSH management systems software proposed by the authors is based on a specific task from four main modules "Employees", "Events", "Equipment", "Ecology" and a number of submodules. In addition, this work uses matrix methods for assessing risks in the "Probability or Consequences of an Event" coordinate system, "Elmeri" system, "Fine Kinney" method, "Risks". Modern expert methods are compared and presented under the title "Five stages of assessment"

Abstract The research dwells on the danger of mud volcanism for human economic activity, namely, oil and gas production. We performed quantitative assessment of mud volcanoes activities, using Azerbaijan and Kerch-Taman region as examples. Average annual number of mud volcanoes eruptions is 3–4 for Azerbaijan and 1–2 for Kerch-Taman region. We estimate the catalogues of mud volcanic eruptions for those areas to be 52 % and 39 % complete, respectively. Mud volcanoes eruptions are quite frequent. In both regions, over 50 % of all recorded eruptions occur within ten years of the latest eruption. Analysis of mud volcanic eruptions catalogues shows that the volume of breccia ejected during an eruption is practically not related to how long the mud volcano was quiescent. Analysis of potential impact of seismicity on mud volcanic activity shows that the probability of mud volcanoes responding to an earthquake is 6 % and 10 % for Azerbaijan and Kerch-Taman region, respectively.
