2. Discerning the Fatigue Crack Growth Behavior of API X65 Steels Under Sequence Loading
Abstract This paper presents the effect of sequence loading on fatigue crack growth of API X65 steel tested in room temperature. Most of pipeline steels are subjected to wide spectrum of loading during the length of service. Influence of load history effect can cause a trickier assessment to the fatigue behaviour. The objective of this study is to determine

3. Guide for Recommended Practices to Perform Crack Tip Opening Displacement Tests in High Strength Low Alloy Steels
Abstract: Fracture mechanics approach is important for all mechanical and civil projects that might involve cracks in metallic materials, and especially for those using welding as a structural joining process. This methodology can enhance not only the design but also the service life of the structures being constructed. This paper includes detailed considera

4. Influence of Hydrogenation on Residual Stresses of Pipeline Steel Welded Joints
Hydrogen embrittlement is a phenomenon that affects the performance of steel used for oil and gas pipelines. This paper presents a study of the effect of hydrogenation on the residual stresses of an API 5L X65 steel pipe. Residual stresses were analyzed by X-ray diffraction technique using the sin2Ψ method. The hydrogenation of base metal and welded joint s

5. Study of Pipeline Steels with Acicular Ferrite Microstructure and Ferrite-bainite Dual-phase Microstructure
Three kinds of X70 steels with the same chemical composition and different microstructures fabricated by varying processes were compared in aspect of the microstructures and mechanical properties using SEM, TEM and tensile testing machine. The experimental results showed that the steel 1 with acicular ferritic microstructure fabricated by thermal-mechanical

6. An overview of heavy oil properties and its recovery and transportation methods
Unconventional oils - mainly heavy oils, extra heavy oils and bitumens - represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to

7. Microstructure and wear resistance of spray-formed supermartensitic stainless steel
Since the early 90's the oil industry has been encouraging the development of corrosion and wear resistant alloys for onshore and offshore pipeline applications. In this context supermartensitic stainless steel was introduced to replace the more expensive duplex stainless steel for tubing applications. Despite the outstanding corrosion resistance of stainles

8. REAL OPTIONS IN PROJECT FINANCE: AN OIL INDUSTRY APPLICATION / OPÇÕES REAIS EM PROJECT FINANCE: UMA APLICAÇÃO NA INDÚSTRIA PETROLÍFERA
The Project Finance structures are increasingly being used to finance investment projects, especially for infrastructural projects. Therefore, a complex legal structure is used to ensure an appropriate allocation of risks to the project stakeholders. This project risk management is very important to ensure the financial viability and success of a structured

9. Modelos e algoritmos para um problema de bombeamento de múltiplos combustíveis em uma rede com um único duto unidirecional / Models and algorithms for a multiple product pipeline on a network with a single unidirectional pipe
One of the most economical and, with respect to the environment, safest ways to transport fuel is to pump them through pipeline networks. However, the several operational constraints that have to be considered turn the planning of these activities into a major challenge. Among the several cenarios in which the problem arises, in this dissertation we investig

10. Alternativas técnico produtivas para o aproveitamento do gás natural da camada pré-sal / Technical productive alternatives to the use of natural gas in pre-salt layer
The Brazilian reserves of oil and natural gas will present a significant growth from the development of the reserves of the pre-salt layer. According to estimates prepared by the EPE and the EIA, the next twenty years, the supply of natural gas will exceed demand. As the transportation sector natural gas has great importance in the formation of the cost of e

11. Estudo de viabilidade do sistema de ancoragem de uma unidade flutuante de produção e armazenamento \"FPSO\" acoplada a um sistema de completação seca \"TLWP\". / Mooring system feasibility study of a floating production and storage unit \"FPSO\" coupled to a dry tree system \"TLWP\".
The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also l

12. RESTARTABILITY OF VISCOPLASTIC MATERIALS IN PIPES / REINÍCIO DE ESCOAMENTO DE MATERIAIS VISCOPLÁSTICOS EM UM TUBO
On of the main problems in the operation of subsea pipelines that convey paraffin oils is the flow startup after long stoppages. Along the path from the reservoir to the platform, the oil experiences significant heat losses, especially to the low-temperature water at the sea bottom. When there is no flow, the oil may reach very low temperatures. Cooling indu
