COURSE OVERVIEW:

While the shell and floor of a storage tank are primary structural concerns, the integrity of appurtenances is vital for the functional safety and environmental compliance of the asset. This course provides a specialized technical focus on the inspection and maintenance of tank nozzles, manways, and roof systems. Participants will learn how these critical penetrations and attachments can become focal points for localized corrosion and stress, often leading to leaks or structural failure if not properly managed.

The scope of this training addresses the mechanical design and reinforcement requirements of nozzles and manways according to API 650 and API 653 standards. We will examine the unique challenges associated with roof systems, including fixed-cone roofs, dome roofs, and the structural supports that hold them. The curriculum emphasizes the identification of degradation in often-overlooked components such as gauging systems, vents, and emergency pressure relief devices, which are essential for preventing tank overpressure or vacuum collapse.

Coverage includes the practical application of non-destructive testing (NDT) to appurtenance welds and the assessment of gasket integrity for manways and clean-out openings. Attendees will investigate the maintenance of roof drainage systems and the replacement of worn-out seals and covers. By the end of this course, participants will be equipped to develop a comprehensive inspection and maintenance program for tank appurtenances, ensuring that these secondary components do not become primary points of failure.

COURSE OBJECTIVES:

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

• Identify the various types of nozzles, manways, and appurtenances on atmospheric storage tanks.
• Analyze the design and reinforcement requirements for shell penetrations per API 650.
• Evaluate the condition of nozzle-to-shell welds using appropriate NDT methods.
• Inspect manway covers, gaskets, and bolting for signs of leakage and fatigue.
• Assess the structural integrity of fixed-roof systems and their supporting rafters.
• Identify corrosion patterns unique to the vapor space and roof underside.
• Inspect and maintain tank venting systems and pressure-vacuum (PV) valves.
• Evaluate the functionality of gauging systems, sample hatches, and stilling wells.
• Analyze the risk of "small-bore" connection failures on tank shells and roofs.
• Develop maintenance procedures for roof drainage systems and emergency overflows.
• Perform settlement assessments specifically focused on nozzle strain and misalignment.
• Document appurtenance findings in accordance with API 653 inspection reporting.

TARGET AUDIENCE:

This course is designed for Tank Inspectors, Maintenance Engineers, Asset Integrity Managers, Terminal Operators, and QA/QC Technicians involved in the lifecycle management of liquid storage tanks.

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:

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