As a kind of NP-hard combinatorial optimization problem, pipe routing design (PRD) is applied widely in modern industries. In the offshore oil and gas industry, a semi-submersible production platform is an important equipment for oil exploitation and production. PRD is one of the most key parts of the design of semi-submersible platform. This study aims to present an improved ant colony algorithm (IACO) to address PRD for the oil and gas treatment system when designing a semi-submersible production platform.

First, to simplify PRD problem, a novel mathematical model is built according to real constraints and rules. Then, IACO, which combines modified heuristic function, mutation mechanism and dynamical parameter mechanism, is introduced.

Based on a set of specific instances, experiments are carried out, and the experimental results show that the performance of IACO is better than that of two variants of ACO, especially in terms of the convergence speed and swarm diversity. Finally, IACO is used to solve PRD for the oil and gas treatment system of semi-submersible production platform. The simulation results, which include nine pipe paths, demonstrate the practicality and high-efficiency of IACO.

The main contribution of this study is the development of method for solving PRD of a semi-submersible production platform based on the novel mathematical model and the proposed IACO.

For the first time since the “limits to growth” debate of the 1970s, we hear serious talk about the prospect of the world running out of oil. In the United States, concerns about reducing dependence on foreign oil have incited debate over the viability of alternative energy sources versus the oil industry's search for new oil “frontiers.” The rancorous dispute over drilling in the Arctic National Wildlife Refuge (ANWAR) has captured the spotlight in this debate. Less controversial, but more significant for the future of U.S. oil production, are the bountiful “deepwater” reserves of the Gulf of Mexico (GOM). Offshore is central to the history of the petroleum industry over the last 50 years, and the GOM is the most explored, drilled, and developed offshore petroleum province in the world. In recent decades, revenue from offshore leasing has been second only to federal income taxes in value to the U.S. treasury. During the last 30 years, the search for oil and gas has continually moved into deeper waters and into new offshore environments. Still, the GOM remains the primary laboratory for technological innovation and regulatory practices. The recent and spectacular revival in production there thanks to deepwater discoveries has strongly reinforced this demonstration effect. As offshore oil assumes a high profile in national development strategies around the world, any effort to analyze the political, social, and economic aspects of offshore exploration and development must use the GOM as a historical precedent or basis of comparison.

Using the case of the Deepwater Horizon blowout in the Gulf of Mexico in 2010, I argue that the catastrophe was less an example of a low probability-high catastrophe event than an instance of socially produced risks and insecurities associated with deepwater oil and gas production during the neoliberal period after 1980. The disaster exposes the deadly intersection of the aggressive enclosure of a new technologically risky resource frontier (the deepwater continental shelf) with what I call a frontier of neoliberalized risk, a lethal product of cut-throat corporate cost-cutting, the collapse of government oversight and regulatory authority and the deepening financialization and securitization of the oil market. These two local pockets of socially produced risk and wrecklessness have come to exceed the capabilities of what passes as risk management and energy security. In this sense, the Deepwater Horizon disaster was produced by a set of structural conditions, a sort of rogue capitalism, not unlike those which precipitated the financial meltdown of 2008. The forms of accumulation unleashed in the Gulf of Mexico over three decades rendered a high-risk enterprise yet more risky, all the while accumulating insecurities and radical uncertainties which made the likelihood of a Deepwater Horizon type disaster highly overdetermined.

Highlights Norwegian regulatory framework with its employee participation tradition. Posits a response of the UK government was the introduction of new offshore regulations with a required need for safety meetings and elected safety representatives. Recognizes, in Canada, that moving into the production phase of the offshore oil industry triggered a renewed interest in offshore safety. Concludes Norway’s amended offshore oil and gas regulations of 1998 placed heavy emphasis on workers’ input to enable all the changes to take place in a correct manner.

The purpose of this research paper is to contribute to strategy theory by differentiating different types of top management narratives and trying to understand the interplay between them as well as the dynamics over time.

The study was designed from an interpretative narrative approach. Narratives were produced from deep interviews and organisational documents covering a period of more than 25 years.

Two kinds of narratives were detected – builders and cleaners. The builders' narratives illustrate how personal life‐stories are embedded in the strategic development processes but the cleaners' narratives are organisational stories without personal life‐stories and cover no actual development. The concept meta‐narrative helped to understand strategic changes over time and was embedded in the myth‐periods involved. The meta‐narrative identified was built on an idea of a going concern and on the role to produce physical large objects for long‐term use.

Owing to the longitudinal design of the study a cyclical pattern with related managerial narratives were produced. The dichotomy builders and cleaners could be developed studying other longitudinal business strategies and also by connections to meta‐narratives derived from more general economic theories.

Builders and cleaners focus on either business or organisational/financial aspects but neither of both. Awareness of this, learning strategic management requires co‐operation between different actors.

The longitudinal design describes and analyzes a cyclical pattern of managerial patterns, while other studies based on narratives cover more limited organisational events in time and space.

There was a time when the inspection of static plant was not a serious consideration. Once erected, it could be expected to give trouble‐free service. Modern plant however, runs to such extremes of efficiency and under such extreme working conditions, that this attitude has had to change.

A method for non‐linear static and dynamic analysis of flexible systems submerged in water is outlined. The systems considered here include cable and beam elements, as well as buoys and clump weights. Contact and lift‐off between members and the sea floor is also accounted for. The formulation used allows for very large deformations and material non‐linearities. Hydrostatic buoyancy and hydrodynamic drag forces are considered throughout the analyses. These capabilities have been implemented in the general purpose non‐linear finite element program FENRIS. Aspects concerning efficient solution of the non‐linear static and dynamic equations are discussed. In particular, an efficient start‐up procedure for analysis of highly flexible systems is described. The paper shows applications involving static and dynamic analysis of a floating structure kept in place by six mooring lines and a flexible riser system.

The chapter considers the significance of the oil and gas industry for the Russian economy. The authors analyze the current state of the oil and gas industry, their specific weight in the structure of Russian GDP, and tax revenues from this industry to the Russian budget that was estimated. We give scenario analysis that considers the problems that the Russian economy may face because of the sanctions, the price fluctuations at the commodity market, and the crisis phenomena in the world economy. The chapter points out that localization of technology production and development of technologies for offshore oil and gas production in the Arctic zone may become an incentive to further ensure import substitution for Russia. At present, the experience of Arctic defense enterprises in the production of equipment for oil and gas production and processing is becoming increasingly popular. The chapter elaborates the most significant examples of the creation of new industries in the Arctic zone, the prospects of seismic exploration on the Arctic shelf, and that localization of production capacities and service bases will allow obtaining a multiplicative incentive for a qualitatively new industrial and infrastructure development of the northern territories. Also, we provide an assessment of the development of liquefied natural gas (LNG) industry, which makes economically attractive use of natural gas on a regional level as LNG opens the way to fuel high-power needs and to long-distance transport.

The purpose of this paper is to propose a practical method of performing maintenance in the offshore industry where engineers have to manage problems such as the high cost of operations, assuring an high availability of the plant, safety on board and environmental protection. Indeed an efficient maintenance method it is necessary in order to offer methods and criteria to select the rights maintenance strategies keeping in to account the environmental, safety and production constrains.

The paper provides an overview of reliability centered maintenance (RCM) and reliability, availability, maintainability methodologies and an integration of the two methodologies in a particular case study in the oil and gas sector.

This paper suggests an improvement of the well-established RCM methodology applicable to industries with high priority level. It is proposed an integration between a reliability analysis and an availability analysis and an application on the offshore oil and gas industry.

The methodology provides an excellent tool that can be utilized in industries, where safety, regulations and the availability of the plant play a fundamental role.

The proposed methodology provides a practical method for selecting the best maintenance strategy considering the equipment redundancy and sparing, the asset’s performance over long time scales, and the system uptime, downtime and slowdowns.
