COURSE OVERVIEW:

Venting systems and overpressure protection are the primary safeguards for atmospheric and low-pressure storage tanks, preventing structural failure during product transfer and thermal changes. This course provides a detailed engineering analysis of the devices and systems used to manage internal pressure and vacuum conditions. Participants will examine the physics of "breathing" in storage tanks, focusing on the volumes of air and vapor that must be exchanged to maintain vessel integrity during filling, emptying, and temperature fluctuations.

The scope of this training encompasses the design and selection of Pressure/Vacuum Relief Valves (PVRVs), emergency vents, and flame arresters in accordance with API 2000 standards. We will investigate the mechanical operation of weighted-pallet and spring-loaded venting devices, analyzing how they respond to varying pressure setpoints. The curriculum covers the critical integration of nitrogen blanketing systems (padding) and vapor recovery units, ensuring that pressure protection is balanced with environmental compliance and product quality preservation.

Coverage also includes the rigorous maintenance and testing protocols required to ensure these safety devices function correctly in corrosive or freezing environments. By focusing on the causes of tank collapses and ruptures, the course provides essential knowledge for preventing catastrophic incidents in tank farms. Through this intensive study, attendants will gain the expertise necessary to size venting systems, troubleshoot valve malfunctions, and manage a comprehensive inspection program for overpressure protection assets.

COURSE OBJECTIVES:

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

1. Apply API 2000 standards for calculating tank venting requirements.
2. Differentiate between normal venting and emergency venting scenarios.
3. Select and size Pressure/Vacuum Relief Valves (PVRVs) for specific tank types.
4. Explain the operation and maintenance of flame and detonation arresters.
5. Design nitrogen blanketing (padding) systems for overpressure protection.
6. Identify the causes of tank "implosion" due to vacuum conditions.
7. Execute functional testing and calibration of venting devices.
8. Evaluate the impact of product vapor pressure on venting design.
9. Diagnose the root causes of valve sticking, leakage, and "chattering."
10. Implement a maintenance schedule for venting systems in corrosive environments.
11. Oversee the installation of emergency relief manhole covers.
12. Assess the risk of bird nests, ice, or debris obstructing vent paths.
13. Integrate venting systems with vapor recovery and emission control units.

TARGET AUDIENCE:

This course is designed for Tank Farm Engineers, Process Safety Managers, Maintenance Supervisors, HSE Professionals, and Terminal Operators.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise 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.
