Operation Phase

Many of the current practices applied for offshore production managing emphasize those aspects related to the efficiency of oil & gas production and exportation. Nowadays, due not only to the inherent technical challenges associated to deep-water applications but also to the increasing importance of the HSE aspects and requirements faced by the industry, a crescent demand to implement a philosophy which focalizes safety, reliability and integrity of their subsea flowing systems is taking place. The handling of monitored data in order to help the pipe operator to control fluid transportation throughout flexible pipes is an old practice performed by Petrobras and other oil companies in the world. However, the idea of acquiring a product which has been conceived, designed and manufactured with both intrinsic monitoring and expert systems is a recent idea. The tendency of the main flexible pipe manufactures is normally to face the problem from the traditional point of view: those systems are considered dissociated one from the other and as appendices to be installed, in the field, after system connection and start-up. Experience demonstrates that the installation of those systems during the operation phase has a number of limitations, restrictions, and associated problems. The main objective of this paper is to present an integrity management strategy based on the concept of the self-monitored flexible riser. Self-monitoring is understood as the own capacity of a product (flexible pipe and components with built-in devices) to acquire data about itself and make use of data from the internal and external environments, during its service life. Monitored data is then processed in order to generate relevant information for the fluid transportation business. The basic premise is to select, during product conception phase, some key-parameters to be further monitored, during the operation phase. The selection is determined by technical criteria depending on the potential failure mechanisms and modes related to the particularities of each different application.

Production Industry

At present, flexible pipes are used worldwide to conduct several fluids within the offshore oil production industry. These flexible pipes are complex composite structures made up of several plastic and steel layers. They are intended to work for a long period of time, something around 20 years. Although the flexible pipes behavior is satisfactory in most applications, they are susceptible to simple damages, for example on the external sheath, which much reduces their service life. The offshore inspection activities are extremely expensive and, given that, these activities need to be very well oriented in order to be effective. This paper describes the Risk Based Inspection Methodology, which is a helpful applicable tool in the integrity management of several flexible pipe systems, allowing to concentrate the efforts where they are really needed. This methodology may be used by the oil companies to reduce overall costs and enhance safety and integrity of the production systems.

Manufacturing History

The population of flexible pipes is increasing exponentially and by definition it is ageing. Over the coming years an increasing number of flexible pipes will reach the end of their design life, therefore prudent operators should focus on understanding the integrity status of their flexible pipes. Understanding and effectively managing the integrity of flexible pipes is necessary to prevent, predict, or detect the presence of any loss of integrity. A detailed understanding of the manufacturing history, operational conditions, any previous repairs and inspection or test history are all required to gain a full insight of the flexible pipe fitness and assess its suitability for continued operation and for any potential life extension beyond the initially intended service life. This paper presents guidelines for developing and implementing an integrity management strategy, which utilises the correct mix of inspection and assessment tools (degradation of internal pressure sheath, fatigue assessment, corrosion and annulus condition monitoring etc.) and operating procedures that will allow the operator to assess the opportunity for life extension of flexible pipes.

On January 4th 2007 TIGF published the following invitation for tenders: “Development and Provision of a Pipeline Integrity Management System”. The project was awarded to Bureau Veritas (BV), who proposed to meet the requirements of TIGF with the Threats and Mitigations module of the PiMSlider® suite extended with some customized components. The key features of the PiMSlider® suite are: • More than only IT: a real integrity philosophy, • A simple intuitive tool to store, display and update pipeline data, • Intelligent search utilities to locate specific information about the pipeline and its surrounding, • A scalable application, with a potentially unlimited number of users, • Supervision (during and after implementation) by experienced people from the oil and gas industry. This paper first introduces TIGF and the consortium BV – ATP. It explains in a few words the PIMS philosophy captured in the PiMSlider® suite and focuses on the added value of the pipeline Threats and Mitigations module. Using this module allows the integrity analyst to: • Prioritize pipeline segments for integrity surveillance purposes, • Determine most effective corrective actions, • Assess the benefits of corrective actions by means of what-if scenarios, • Produce a qualitative threats assessment for further use in the integrity management plan, • Optimize integrity aspects from a design, maintenance and operational point of view, • Investigate the influence of different design criteria for pipeline segments. To conclude, TIGF presents the benefits of the tool for their Integrity Management department and for planning inspection and for better knowledge of their gas transmission grid.

Abstract While Floating Offshore Wind (FOW) represents a significant opportunity to foster wind energy development and to contribute to remarkable CO2 emissions reductions, its associated operational costs are still substantially above grid parity, and significant innovation is needed. MooringSense is a research and innovation project which explores digitisation technologies to enable the implementation of risk-based integrity management strategies for mooring systems in the FOW sector with the aim to optimise Operations and Maintenance (O&M) activities, reduce costs, and increase energy production. As part of this project, a risk-based assessment methodology specific for the mooring system of Floating Offshore Wind Turbines (FOWT) has been developed; this allows the development of a risk-based Mooring Integrity Management Strategy that can result in more cost-effective inspection planning. The methodology shall utilise the information made available by numerical tools, sensors, and algorithms developed in the project to update the risk level of the mooring system and set the required plan to mitigate the risk. Leveraging the additional information from monitoring technologies and predictive capabilities to determine the mooring system condition and remaining lifetime, the strategy provides the criteria for optimal decision making with regards to selection of O&M activities. The risk-based strategy developed allows for optimal planning of inspection and maintenance activities based on dynamic risk level that is periodically updated through the interface with the Digital Twin (DT). The validation of the strategy will demonstrate potential cost saving and economic advantages, however, it is expected that the overall MooringSense approach can reduce FOW farm operational costs by 10-15% and increase operational efficiency by means of an Annual Energy Production increase by 2-3%. The MooringSense project comprises of the development and validation of innovative solutions coming from multiple disciplines such as numerical modelling, simulation, Global Navigation Satellite System (GNSS), Structural Health Monitoring (SHM), and control systems which will provide valuable input to the risk-based mooring integrity management strategy.

This article considers the problem of processing and disposing of oil sludge of various origins. Large oil companies are concerned about the problem of incomplete processing of oil sludge. The most hazardous from an environmental point of view include oil sludge formed at all stages of oil production, transportation and refining. In recent years, oil-producing enterprises have introduced various technological solutions aimed at waste management into production, but there is no single method for processing oil sludge for the purpose of neutralization and disposal. All known oil sludge processing technologies by processing methods can be divided into the following groups: thermal - burning in open barns, furnaces of various types, obtaining bitumen residues; physical - burial in special cemeteries, separation in a centrifugal field, vacuum filtration and filtration under pressure; physical and chemical - the use of specially selected reagents that change the physical and chemical properties, followed by processing on special equipment; and biological - microbiological decomposition in the soil directly in storage, biothermal decomposition. Each of them, while having certain advantages, also has its drawbacks. For over 50 years, microwave heating technology has been used in industry. To present the advantages of this method, one needs to turn to the theory of microwave heating. Keywords: oil sludge, oil waste, influence of electromagnetic fields, water-in-oil emulsions

The analgesic paracetamol (N-acetyl-4-aminophenol, APAP) is commonly used to relieve pain, fever and malaise. While sales have increased worldwide, a growing body of experimental and epidemiological evidence has suggested APAP as a possible risk factor for various health disorders. To perform internal exposure-based risk assessment, the use of accurate and optimized biomonitoring methods is criticical. However, retrospectively assessing pharmaceutical use of APAP in humans is challenging because of its short half-life. The objective of this study was to address the key biomonitoring issues with APAP using current standard analytical methods based on urinary analyses of free APAP and its phase II conjugates. Using non-targeted analyses based on high-resolution mass spectrometry, we identified in a controlled longitudinal exposure study with male volunteers, unrecognized APAP metabolites with delayed formation and excretion rates. We postulate that these metabolites are formed via the thiomethyl shunt after the enterohepatic circulation as already observed in rodents. Importantly, the conjugated thiomethyl metabolites were (i) of comparable diagnostic sensitivity as the free APAP and its phase II conjugates detected by current methods; (ii) had delayed peak levels in blood and urine compared to other APAP metabolites and therefore potentially extend the window of exposure assessment; and (iii) provide relevant information regarding metabolic pathways of interest from a toxicological point of view. Including these metabolites in future APAP biomonitoring methods provide an option to decrease potential underestimation of APAP use and challenges the notion that the standard methods in biomonitoring based exclusively on the parent compound and its phase II metabolites are adequate for human biomonitoring of non-persistant chemical such as APAP. <br>

We talk about “the energy transition” as if it were some type of unified, global event. Instead, numerous approaches to energy transitions are taking place in parallel, with all of the “players” moving at different paces, in different directions, and with different guiding philosophies. Which companies are best positioned to survive and thrive, and why? This article takes a look at what several top energy research and business intelligence firms are saying. What a Difference a Year Makes Prior to 2020—in fact, as recently as the 2014 bust that followed the shale boom—the oil and gas industry weathered downturns by “tightening their belts” and “doing more with less” in the form of cutting capital expenditures and costs, tapping credit lines, and improving operational efficiency. Adopting advanced digitalization and cognitive technologies as integral parts of the supply chain from 2015 to 2019 led to significant performance improvements as companies dealt with “shale shock.” Then, in 2020, a strange thing happened. Just as disruptive technologies like electric vehicles and solar photovoltaic and new batteries were gaining traction and decarbonization and environmental, social, and governance (ESG) issues were rising to the top of global social and policy agendas, COVID-19 left companies with almost nothing to squeeze from their supply chains, and budget cuts had a direct impact on operational performance and short-term operational plans. To stabilize their returns, many oil and gas companies revised and reshaped their portfolios and business strategies around decarbonization and alternative energy sources. The result: The investment in efforts toward effecting energy transition surpassed $500 billion for the first time in early 2021 ($501.3 billion, a 9% increase over 2019, according to BloombergNEF) despite the economic disruption caused by COVID-19. According to Wood Mackenzie, carbon emissions and carbon intensity are now key metrics in any project’s final investment decision. And, Rystad Energy said that greenhouse-gas emissions are declining faster than what is outlined in many conventional models regarded as aggressive scenarios. In Rystad’s model, electrification levels will reach 80% by 2050. A Look at the Playing Field: Energy Transition Pillars In a February 2021 webinar, Rystad discussed what leading exploration and production (E&P) companies are doing to keep up with the energy transition and stay investable in the rapidly changing market environment. The consulting firm researched the top 25 E&P companies based on their oil and gas production in 2020 and analyzed how they approach various market criteria in “three pillars of energy transition in the E&P sector” that the firm regards as key distinguishers and important indicators of potential success (Fig. 1). The research excludes national oil companies (NOCs) except for those with international activity (INOCs). Rystad says these 25 companies are responsible for almost 40% of global hydrocarbon production and the same share of global E&P investments and believes the trends within this peer group are representative on a global scale.

The Web

Web Accessibility is a hot topic today. Striving for social inclusion has resulted in the requirement of providing accessible content to all users. However, since each user is unique, and the Web evolves in a decentralized way, little or none is known about the shape of the Web’s accessibility on its own at a large scale, as well as from the point-of-view of each user. In this chapter the authors present the Web Accessibility Knowledge Framework as the foundation for specifying the relevant information about the accessibility of a Web page. This framework leverages Semantic Web technologies, side by side with audience modeling and accessibility metrics, as a way to study the Web as an entity with unique accessibility properties dependent from each user’s point of view. Through this framework, the authors envision a set of queries that can help harnessing and inferring this kind of knowledge from Web graphs.
