“…Furthermore, the combination of these factors, if not adequately considered in the design, will lead to an unplanned shutdown. (Vanaei, Eslami, & Egbewande, 2017) & (Xu, Wang, Li, Wang, & Su, 2016). As mentioned earlier, there are two significant challenges arise in pipelines, which is corrosion and joining, these two significant challenges are discussed in below sections.…”

Great thanking to almighty God for giving me the patience and ambitious and blessing me to complete this work. I would like to give my sincere thanks also to my supervisor, professor Dr. Elsadig Mahdi Saad for his supporting, encouraging and advising throughout the thesis preparation, and for his assisting and providing of all necessaries to carry out this work. Finally, yet importantly, I would like to express my thanks and appreciate to the workshop team at Qatar University, Mr. Sunith & Mr. Judith for their help in preparing the pipe samples, and to Eng. Mohamed Karim & Eng. Mohamed Gebril for their exceptional efforts and help in carrying out the experiments. vii TABLE OF CONTENTS

“…Also, submerged pipes external corrosion is determined by water chemistry. (Vanaei, Eslami, & Egbewande, 2017). On the other hand, internal corrosion is anticipated in oil and gas transportation, which involves a very high corrosive media like hydrogen sulfide (H 2 S) and carbon dioxide (CO 2 ).…”

“…Table 4 depicts the distributions of these categories where it can be noticed that general and pitting corrosion cover around 90% in both inspections and pipe walls, but there is still a relevant number of axial and circumferential grooving at the inner wall. The absence of pinholes and slotting defects (both axial and circumferential) may suggest that ultrasonic tools were implemented for both inspections [49]. However, MFL tools were used instead, and circumferential slotting defects are actually included in these ILI reports, but their corresponding dimensions do not fit into the POF boundaries for this defect type, so this classification was ignored.…”

A condition-based dynamic segmentation of large systems using a Changepoints algorithm: A corroding pipeline case

et al. 2020

Large structures are systems composed by a significant number of components with parallel or series distributions. How these components fail and interact, aggravate the complexity of the main structure reliability calculation. Some methods commonly proposed to reduce this complexity by dividing the system into segments of similar properties using dynamic or static approaches. Dynamic segmentations may depend on how aggressive is the structure's surrounding conditions (e.g., the soil properties). Static segmentations could be given by fixed distances. However, in a few cases, these divisions follow a condition-based approach. This paper proposes an alternative dynamic segmentation to identify preliminary critical segments based on a Changepoint approach and data obtained from inspections. Changepoints algorithms have been used to determine changes in spatial measurements for a further reliability evaluation with appropriate limit state functions. This work focuses on onshore pipelines subjected to corrosion defects based on information obtained from In-Line Inspections (ILI). Onshore pipelines cross through a variety of soils, water corridors, and densely populated areas promoting spatial-dependent degradation processes like corrosion. ILI inspections are commonly used to identify the condition of the pipeline in terms of the remaining wall and location of metal loss at the inner and outer walls by using magnetic or ultrasonic instruments. Based on a burst failure limit state, the segments obtained with the changepoints approach are compared with a soil and static segmentations. The results indicate that the proposed approach could identify the main critical points of the pipeline using segments with statistical significance.

“…Corrosion is seen in all areas of life and in all industries to some extent. For instance, air oxidation of hot steel results in formation of a film of red-brown ferric oxide [1]. Within the petroleum producing industry, electrochemical corrosion is responsible for billions of US dollars of costs associated with the breakdown of the Figure 1.…”

Corrosion Strategy in Oil Field System

Crude oil is the main economic supply in many countries. Corrosion has been considered as the first fatal factor destroying the crude oil plants such as crude oil equipment, oil wells, separation vessels, storage tanks, and pipelines. This is the main reason encouraging many companies and researchers to develop new technological methods to manipulate corrosion. In this review, we discuss the types of corrosion, corrosion control methods (chemical and non-chemical methods), corrosion removal methods and corrosion monitoring process (direct and indirect measurement of corrosion). In addition some perspectives on SRB bacteria, types of inhibitors and gases removal methods were provided.
