Interim Measure

Abstract Engineered enclosures for the repair of piping, often referred to as clamps, are used to restore the integrity of in-service piping components as an interim measure until the damaged components can be repaired. They are typically used in the petroleum refining and chemical process industries, nuclear and non-nuclear utilities, and other on-shore and offshore facilities in the oil and gas industry. This type of enclosure has typically been viewed as a short term repair with a limited design life. However, it is the authors’ experience that properly engineered and installed enclosures perform in a manner consistent with the design criteria covering the original piping component(s) to which they have been installed. To investigate this further, a series of tests were conducted on several engineered enclosures that had been recently removed to replace the damaged component. Tests were also conducted on several new constructed enclosures of a similar configuration and size to those that had been recently removed. An analytical approach was also performed on one such enclosure-pipe configuration to support and study the experimental results in detail. This paper presents and summarizes the tests, analyses, and results from this work. The results provide information that can benefit users, standards developers, and regulatory authorities in better understanding the considerations affecting the design life of engineered enclosures.

There is an increasing emphasis on the importance of managing human factors to achieve improved safety and business performance in the chemical process industries and resource sector. Major process safety accidents, including those at Texas City, Varanus Island and Montara have again highlighted the importance of addressing this aspect of performance. Recently the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) announced an additional focus on human factors as part of their regulatory activities, noting that these factors are relevant to performance across safety, integrity, and environmental management. This extended abstract explains how the subject of human factors in process safety has been defined in the UK, categorised by the top 10 key topics. How this targeted approach helps manage this aspect of process safety performance is also discussed. Finally, this extended abstract shows how safety culture and behavioural safety are not the same as human factors. Case studies of the oil and gas industry show how attending to the top 10 delivers benefits by strengthening the effectiveness of management systems, and improving human reliability. This extended abstract directs the reader to a range of high-quality, open-source research, guidance, tools, and techniques to improve across the top 10 human-factors subjects in process safety.

Corrosion Under Insulation

Abstract Risk Based Management of Corrosion Under Insulation, DNVGL-RP-G109© Corrosion Under Insulation (CUI) is a major challenge for different process industries. Today it is managed in many ways, ranging from full removal of insulation to minimal maintenance including some inspection with insufficient non-destructive testing. These two extremes exhibit a lack of understanding and a lack of systematic approach in managing the CUI risk, globally. The paper will describe the results from a recent (2017-2019) CUI Joint Industry Project (JIP) where the oil and gas industry in the North Sea area has established a methodology for managing the CUI threat. In this context managing the CUI threat involves risk assessment, risk mitigation, risk update and experience transfer in a systematic manner. The methodology assesses four CUI barriers: material, coating, water wetting and design. DNV GL has made this methodology available for the industry in DNVGL-RP-G109 "Risk Based Management of Corrosion Under Insulation" Copyright © DNV AS. 2019 All rights reserved.

Subject Increased African offshore exploration Significance Offshore West and Southern Africa is seeing a revival of exploration interest as the upstream oil and gas industry recovers following the 2014 oil price crash. Oil majors such as ExxonMobil and BP have snapped up acreage, while firms that already have a footprint in the region are expanding and announcing new drilling plans. The upsurge in activity will bring a short-term economic boost to the countries concerned but -- as with past waves of exploration -- public expectations of imminent windfalls will have to be carefully managed. Impacts Ports and service companies supporting exploration will see an upturn in activity. Pressure will grow on national oil companies and government bodies to improve expertise and infrastructure for future discoveries. Existing licence-holders will face pressure from regional governments to quickly pursue exploration or risk being replaced.

Abstract Safety instrument system is composed of sensor, logic solver and final actuator. It is widely used in process industry, such as oil and gas industry, chemical industry, metallurgy and electric power industry. It is an important measure to ensure the safety of production, which can effectively avoid the potential danger to people, equipment and the environment. However, when it breaks down, the consequences can be expected to be extremely serious. Therefore, HIPPS requires low risk, so it is necessary to quantitatively evaluate the dynamic performance of HIPPS to ensure the high safety of HIPPS during the design life cycle. In this paper, a Bayesian network based method is proposed to evaluate the dynamic performance of HIPPS. The effects of different detection methods and maintenance methods on the dynamic performance of HIPPS were analyzed quantitatively. The results show that the performance of the system has been improved obviously after maintenance. Compared with the traditional method, the performance of HIPPS is improved by introducing partial stroke test. The sensitivity analysis shows that the failure rate has a great influence on the risk of HIPPS valve. Increased coverage of PST may improve the performance of HIPPS.

Federal tax revenues from the main sectors of the Russian economy after the 1998 crisis are examined in the article. Authors present the structure of revenues from these sectors by main taxes for 1999-2003 and prospects for 2004. Emphasis is given to an increasing dependence of budget on revenues from oil and gas industries. The share of proceeds from these sectors has reached 1/3 of total federal revenues. To explain this fact world oil prices dynamics and changes in tax legislation in Russia are considered. Empirical results show strong dependence of budget revenues on oil prices. The analysis of changes in tax legislation in oil and gas industry shows that the government has managed to redistribute resource rent in favor of the state.

The article deals with the issues of political and economic power as well as their constellation on the market. The theory of public choice and the theory of public contract are confronted with an approach centered on the power triad. If structured in the power triad, interactions among states representatives, businesses with structural advantages and businesses without structural advantages allow capturing administrative rents. The political power of the ruling elites coexists with economic power of certain members of the business community. The situation in the oil and gas industry, the retail trade and the road construction and operation industry in Russia illustrates key moments in the proposed analysis.
