Structural monitoring of subsea structures is widely used subsea in the oil and gas industry. Monitoring may be performed to keep track on position, movements, loads and fatigue accumulation. BOPs may have motions sensors installed to monitor the lower flex joint angle and the movements of the BOP itself. Installing subsea equipment like templates or conductors may also require monitoring to ensure the installation is within the set requirements. Motion sensors containing accelerometers and gyroscopes are commonly used for these applications. These sensors are well suited for accurately determining inclination, but the sensors estimate displacements poorly. An alternative approach for such measurements is to use machine vision. The machine vision tracks selected features from a video feed and calculates position, displacement and inclination directly. A benefit of this monitoring technique is that it does not require any hardware on the actual structure, only a camera and a tracking software. Two video tracking algorithms are proposed for tracking. One marker based algorithm that require a pre-installed visual marker, and a markerless algorithm that uses natural features on the structure. The article presents the accuracy and project examples of in-field use of these algorithms.

Indigenous Land

In the settler colonial context of so-called Canada, oil and gas projects are contemporary infrastructures of invasion. This article tracks how the state discourse of “critical infrastructure” naturalizes the environmental destruction wrought by the oil and gas industry while criminalizing Indigenous resistance. I review anthropological work to analyze the applicability of the concept of infrastructure to Indigenous struggles against resource extraction. Drawing on fieldwork conducted in Indigenous land defense movements against pipeline construction, I argue for an alternative approach to infrastructure that strengthens and supports the networks of human and other-than-human relations that continue to make survival possible for Indigenous peoples.

Long Term Impact

The traditional planning for decommissioning oil and gas projects has included the option to remove platforms from the project area leaving the site clear for other uses. However, decommissioning presents a number of opportunities for alternative uses for facilities that are relatively close to the coast and in developing areas.This paper examines the potential for the alternative use of facilities on the North West Shelf using the WMC operated Airlie Project as an example.Airlie Island presents an opportunity to conduct a number of research activities which would have the capability to enhance the understanding of the natural environment in the region and to gain better understanding of the long-term impact of the oil and gas industries impact on the natural environment. There is also the supplementary opportunity to conduct engineering research applicable to the oil and gas industry without the distraction and hazards of an operating field to interfere with the research projects. Allied to these possibilities is the potential to conduct research applicable to tourism and fishing related activities which are beginning to exert more pressure and the North West Shelf environment than has been the case in the recent past.In addition to the research opportunities, there exists the potential to manage Airlie Island as a support base for tourism activities on a commercial basis. The example presented could easily be applied to other projects nearing decommissioning.

The Waves

About 70% of the earth’s surface area is covered with water. Due to the sea level rise and increasing population in coastal areas we need to use our oceans more for energy production, food production, working and living. In the present paper we discuss the results of a model test for a floating mega island in large waves up to 15.5 m significant wave height. The objective of this study is to investigate the motion response and loads on the island. These results may then be used to support further innovation of these islands. The proposed island comprises 87 large floating triangles that are connected to one another. Together they form a flexible floating island of 1.5 by 2 km in cross-section at scale 1:250. The results are presented for the motion response of the island as well as the forces between the islands triangular modules and the mooring loads. These were measured using forces transducers and motion sensors. The present work is part of a conceptual test carried out at MARIN. The island modules are interconnected with springs and fenders. This method is much similar to what is used in side by side offshore operations in the oil and gas industry. Due to the flexibility in the connections the island will follow the waves in high seas. The forward two rows of the island will move in phase with the sea and therefore the amount of green water is much smaller than for a rigid island.

The Government

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.

Geopolitical Risks

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest
