Equipment and Piping failures present the greatest risk to the integrity of metallic components in down-stream petroleum sector. The implementation of Mechanical Integrity (MI) systems in the downstream petroleum sector differs based on the interpretation of various Industry standards, etc. Despite implementation of MI system, failures leading to loss of containment (LOC) are ubiquitous in aging plants. Robust and effective corrosion assessment requires focused effort from many disciplines within the organization to ensure that threats and monitoring regime are fully, identified, understood, and managed.

Corrosion risk assessment is an effective tool for screening, assessing, and managing threat at the segment and sub-segment level. Consequently, effective equipment and piping segmentation based on fluid corrosivity is paramount towards initiating corrosion-risk assessment or risk-based inspection (RBA/RBI) program. Corrosion assessment allows a review of inspection and operation data to review barriers and mitigations to ensure safe operations in accordance with the design intent. Corrosion risk management is undertaken through the following key steps; threat identification, risk assessment, risk response and risk review. This continuous, cyclical process is required to ensure that all risks are appropriately mitigated or managed.

In 1950s, as an important measure to improve the corrosion resistance of base metal, internal coating pipes was first applied to sour crude oil and natural gas pipelines [1]. Among the coating systems, FBE coating has good impact resistance, bending resistance, high bonding strength, good resistance for acid, alkali, salt, oil and water fluid. The coating can reduce the internal surface roughness friction resistance of piping & pipeline to reduce project investment.

Pipelines have been the main transportation pattern of oil and gas because of their safety and economy, which are considered as the lifeline of offshore oil and gas transportation. With the booming development of offshore oil industry, the frequency of pipeline leakage is also increasing. Corrosion is one of the important factors due to some characteristics such as operating environment, service life and transportation medium, etc., which damages the integrity of the pipeline and damage the normal operation of pipelines. Furthermore, leakage accidents caused by pipeline corrosion have occurred all over the world, accounting for 70~90% of total accidents, which has caused huge economy losses and catastrophic environmental damage.

At present, there were ten common crossing modes in long-distance oil and gas pipelines[1,2]. There were six ways of tunneling, such as large excavation, horizontal directional drilling, shield tunnel, drilling and blasting tunnel, ramming pipe and pipe jacking. There were four ways of spanning methods, such as truss crossing, arch bridge crossing, suspension cable crossing and cable-stayed bridge crossing. Crossing by shield tunneling, as a pipeline laying method with high mechanization and automation, extensive applicable strata and high safety, has been widely used in recent years.
