New Resources For API 2350 Compliance and Tank Overfill Prevention Measures

Many refinery and storage terminal operators are preparing their facilities for API RP 2350compliance. This recent guideline, published by the American Petroleum Institute, outlines recommended practices for the prevention of tank overfill incidents. While the API 2350 standards have been out since May 2012, many operations are still managing compliance initiatives, since changes to recommended practices are complex and often affect numerous tanks and vessels throughout a facility.

Magnetrol® has been at the forefront of efforts to provide the oil and gas industry with detailed information about effective API 2350 compliance and tank overfill prevention measures. Our latest resource – the API RP 2350 compliance podcast series – makes it easy for operators to access comprehensive data to help manage their compliance programs. The series of four podcasts breaks down the new tank overfill prevention standards into four topics.

Topic 1 – Summary of Changes: The fourth edition of API 2350 updates standards associated with liquid and tank types. It also recommends the development of an overfill prevention process (or OPP), as well as an overfill prevention system (OPS), a component of the OPP that addresses equipment and personnel guidelines. Our first podcast details the scope of these changes.

Topic 2 – Overfill Prevention Process: The OPP, a comprehensive system of parameters, procedures and documentation for overfill prevention, is a new recommended practice under API 2350’s fourth edition. The OPP consists of five categories: a management system; a risk assessment system; operational parameters (defining levels of concern and tank categories); documented procedures; and equipment system requirements. Each category is discussed in the second podcast.

Topic 3 – Levels of Concern and Tank Categories: Our third podcast outlines the updates made to the definition of and parameters for levels of concern. At a minimum, three levels of concern – Critical High level, High-High level and Maximum Working level – must be identified for each tank. Response times are part of the operating parameters for levels of concern. Additionally, tank categories are identified by levels of staffing and include: Category 1, a fully attended tank; Category 2, a semi-attended tank; and Category 3, an unattended tank. The API 2350 standards identify the scope of acceptable automatic tank gauging (ATG) and alarms in relation to tank categories.

Topic 4 – Action Steps for Terminal Preparedness: Podcast 4 provides operators with a recommendation for action steps to take to prepare refineries and terminals for API 2350 compliance. The steps include:
• Identifying applicable tanks
• Assessing overfill risk for each tank
• Defining category, response time and levels of concern for each tank
• Selecting required instrumentation
• Defining a management system
