COURSE OVERVIEW:

The protection of midstream and downstream assets requires a specialized engineering approach that accounts for complex geometries and varying environmental interfaces. This course focuses specifically on the design and implementation of cathodic protection systems for buried pipelines and the complex floor structures of aboveground storage tanks. Participants will explore the unique challenges associated with long-line current distribution, including the attenuation of protective potentials over vast distances and the shielding effects often encountered in tank foundations.

The scope of the curriculum covers the technical differentiation between localized protection for tank farms and the distributed systems required for cross-country pipeline networks. Detailed analysis is provided on the selection of anode configurations, such as linear anodes for pipelines and ribbon anodes for tank floors, to ensure uniform current spread. The course also addresses the integration of secondary containment liners in tank designs and how these dielectric barriers influence the path of the protective current and the placement of reference electrodes.

Coverage includes the application of industry-standard modeling for current distribution and the rigorous calculation of longitudinal resistance in pipeline steel. Participants will study the mitigation of stray currents at pipeline crossings and the management of interference in congested industrial corridors. By the conclusion of the training, attendees will be equipped to develop comprehensive corrosion control strategies that safeguard high-value infrastructure against the catastrophic failures associated with localized pitting and environmental stress cracking.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Design customized cathodic protection systems for the external surfaces of buried and submerged pipelines.
2. Develop specialized protection schemes for the undersides of aboveground storage tank (AST) floors.
3. Calculate current attenuation along a pipeline to determine the optimal spacing of transformer rectifiers.
4. Evaluate the impact of secondary containment liners on current distribution for tank bottom protection.
5. Specify the installation requirements for linear anodes and grid systems in congested pipeline corridors.
6. Determine the requirements for electrical isolation using monolithic joints and flange insulation kits.
7. Analyze the interference risks associated with pipeline crossings and parallel high-voltage AC lines.
8. Design effective grounding and surge protection for pipelines to manage lightning and fault currents.
9. Implement monitoring systems for tank floors, including the use of permanent reference electrodes and perforated conduits.
10. Assess the effectiveness of cathodic protection in the presence of pipeline "deadlegs" and stagnant zones.
11. Use specialized software or mathematical models to predict the spread of protection in complex tank farms.
12. Create detailed commissioning reports that verify compliance with API 651 and NACE SP0169 standards.

TARGET AUDIENCE:

This course is intended for pipeline engineers, tank farm managers, corrosion technicians, integrity specialists, and project engineers involved in the construction and maintenance of oil, gas, and water transportation and storage facilities.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
