The complex system of control, monitoring and improvement of power quality in power supply systems of oil production enterprises is designed, which also allows to decrease the negative influence on the environment. The main reasons for mismatch between the actual electricity quality in distribution network and the requirements for oil producing businesses, as set forth by reference documents, have been disclosed. Provided are recommendations in connection with the arrangement and the practical implementation of technical measures for controlling and improving the quality of electric power in oil producing enterprises power supply systems.

Goriva i maziva koja se upotrebljavaju u avijaciji zahtijevaju posebne standarde kvalitete i posebne karakteristike kako bi učinkovito zadovoljili potrebe modernih letjelica u pogledu postojanosti i učinkovite iskoristivosti, ali i kako bi kvalitetno odgovorila na izazove specifičnih atmosferskih i fizikalnih okolnosti vezanih za zračni promet. U ovome radu predstavljene su najčešće korištene vrste goriva i maziva, pri čemu se proučavaju njihove karakteristike te prednosti koje imaju pred drugim vrstama goriva i maziva kao i njihovu primjenu ovisno o modelima motora letjelica. Također se u sklopu rada prikazuje utjecaj na okoliš goriva i maziva u avijaciji te samim time utjecaj na okoliš općenito avijacije, a proučavaju se i troškovi održavanja zrakoplova koji su posebno važni stoga što se nastoji što manjim intervencijama u sami zrakoplov smanjiti trošak održavanja i samim time se pojavljuje potreba za dugotrajno postojanim mazivima. Aviation fuels and lubricants that require to meet special standards of quality and special features to effectively fulfil the needs of modern aircrafts in terms of stability and efficient utilization, but also to well respond on the challenges of specific atmospheric and physical conditions related to air transport. This study presents the most commonly used types of fuels and lubricants, where the focus is pointed to their characteristics and advantages over other types of fuels and lubricants as well as their application depending on the model of engine. Study also examines environmental impact of fuels and lubricants in aviation and therefore the impact on the environment in general aviation, as well as question of maintenance costs of aircraft which is particularly important because modern companies are seeking the lowest possible interventions in their own aircraft to reduce the cost of maintenance and thus there is a need for long-term stable lubricants.

The oil and gas sector in Ethiopia, currently at a very early stage of development, shows good potential for development on the long-run. The sector will benefit from strategies and policies to implement the broader vision for the sector. Development of the oil and gas sector in Ethiopia has the potential to transform the country’s economy. To this end, the Government of Ethiopia (GoE) has requested technical assistance and capacity building support from the World Bank as part of a wider package of support provided by the Bank (in coordination with other development partners) to develop the extractive industries (oil, gas, and mining) sector of Ethiopia. The main objective of the work to be undertaken, is to provide guidance and build capacity in GoE as it undertakes the wider update of its policy, legal, and regulatory framework of the oil and gas sector. Adam Smith International (ASI) was contracted to review the policy and regulatory framework for the oil and gas sector and provide recommendations. This final report on policy and regulatory options has been prepared at the conclusion of the analytical stage of the project, and was preceded by the initiation report submitted in July 2015. This report has two objectives. Firstly, to provide a comprehensive review of the current policy of the GoE towards the oil and natural gas sector. Secondly, to evaluate the regulatory framework in terms of good international practice.

The study represents a background study for the proposed Uganda Country Economic Memorandum (CEM), which seeks to address the issue of efficient use of oil resources and examine synergies between the oil industry and the rest of the economy, through growth poles or linkages. The oil industry can help Uganda to promote robust growth in the economy. However, it is important to keep in mind that it will take a number of years until oil revenues start flowing into Uganda s economy. After the Final Investment Decision (FID) is reached, it will take time to develop the oil fields and start oil production. In the meantime, there are immediate opportunities opening up for Uganda s businesses to supply the oil industry with goods and services. In most cases, Uganda s suppliers, especially micro, small and medium enterpises (MSMEs), are not expected to become first tier contractors to the International Oil Company (IOCs). The main objective of this study is to provide recommendations to the Government of Uganda (GoU) on policies and strategies of leveraging the oil discoveries for the development of the national economy in order to transform the oil resources into sustained growth. The study reviews the typology of policies for local sourcing used in the world. It includes ample examples of other countries experiences with developing their local content policies and providing support to priority sectors to boost local content which could be useful for Uganda from the standpoint of lessons learned. The study conducts a detailed analysis of the binding constraints faced by domestic oil and gas suppliers in Uganda, takes stock of existing national content support initiatives and identifies areas which are in urgent need of further support. The study examines how the oil sector can be used as a driver of agriculture and fisheries sectors in the Albertine Region and other regions of Uganda from the standpoint of food supply to the oil camps.

High volatility in the world prices of petroleum has been a characteristic feature of the global economy in the last decade. World petroleum prices increased four-fold between 2004 and 2008 and, and following a drop in prices in the second half of 2008, petroleum prices have been rising again, and they are several times higher than they were two decades ago. Since high and volatility of prices is likely to be a permanent feature of the global economy for the foreseeable future, they merit a reconsideration of the national transport and taxation policies that were put in place when fuel prices were not such a significant component of trade-related transactions costs in Sub-Saharan Africa (SSA) countries. Transport practices that were based on the assumption of low price of fuel are not sustainable, and policies neglect fuel efficiency considerations through lowering the fuel consumption of vehicles measures are no longer sustainable. Efficient and low transport cost is essential to achieve regional economic integration and strengthen Africa's competitiveness in external markets. Higher diesel prices also impact on the prices of all other goods which use diesel as an intermediate input. The most significant among them with implications for the poor in low-income developing countries is food, on which the poor spend a disproportionately high share of their total household expenditures. This report is in three parts in the first part, transport fuel prices in the countries of SSA are compared with those of other regions of the world. The comparison is not only in terms of the actual retail prices but also, but taking account of per capita incomes and truck revenues, also in terms of affordability. This Part also provides evidence of the make-up of transport fuel prices in SSA countries, as a first step in assessing how they can be dealt with. The second part provides new evidence of the impact of these high fuel prices on the export competiveness of a sample of six SSA countries. It also provides a shorter description of the results of a study of the impact of fuel prices on logistics costs in Central America, since so far there have not been any studies of the impact of high transport fuel prices on logistics and food costs in SSA countries. The third part deals with the ways in which the impact of high transport fuel prices can be addressed. Two main areas of action are described, those that would reduce the retail price of transport fuel and those that would increase fuel efficiency, so they impact of high prices would be reduced. This section focuses on diesel fuel, as this is by far the most used by the trucks that transport export products and are involved in domestic logistics. This section concludes with some ideas on what could be done next to make progress on implementing the most promising ideas for reducing the impact of high transport fuel prices.
