COURSE OVERVIEW:

Floating roof tanks are critical assets for the storage of volatile petroleum products, designed primarily to minimize vapor loss and ensure safety. This course provides a technical exploration of the design, operation, and maintenance of both Internal Floating Roofs (IFR) and External Floating Roofs (EFR). Participants will learn how the floating roof system functions as an integrated unit, focusing on the critical interface between the roof, the tank shell, and the sealing mechanism.

The scope of this training addresses the vital issues of seal integrity and emission control, which are regulated by stringent environmental and safety standards. We will examine the various types of primary and secondary seal designs, including mechanical shoe seals, liquid-filled seals, and foam-log seals. The curriculum emphasizes the identification of common failure modes, such as seal gaps, rim fires, roof sinking, and drainage system failures, providing attendees with the knowledge to maintain these systems in peak condition.

Coverage includes specialized inspection techniques required for floating roofs, both in-service and out-of-service. Attendees will investigate the impact of shell out-of-roundness on seal performance and the technical requirements for roof support legs, vents, and gauging systems. By the end of this course, participants will be equipped to manage floating roof tank integrity, ensuring compliance with environmental regulations while maximizing operational safety and product quality.

COURSE OBJECTIVES:

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

• Identify the design differences between External (EFR) and Internal (IFR) floating roof systems.
• Explain the role of floating roofs in vapor suppression and fire prevention.
• Analyze the mechanical components of primary and secondary seal systems.
• Evaluate the performance of mechanical shoe seals versus resilient foam seals.
• Conduct seal gap measurements in accordance with environmental regulatory requirements.
• Calculate vapor emissions from floating roof tanks using industry-standard formulas.
• Inspect roof drainage systems, including drains, sumps, and flexible hoses.
• Identify the causes of floating roof instability and "sinking" events.
• Assess the impact of shell distortions and weld peaking on seal integrity.
• Perform in-service visual inspections of floating roofs using drones and cameras.
• Implement maintenance strategies for rim seals, weather shields, and wipers.
• Develop safety procedures for personnel working on or around floating roofs.

TARGET AUDIENCE:

This course is designed for Tank Farm Managers, Maintenance Engineers, Inspection Engineers, Environmental Compliance Officers, Plant Operators, and HSE Professionals involved in the operation and maintenance of large-scale 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:

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.
