Guidebook for Overfill Prevention
and Tank Gauging

The public, the regulatory community and the industry demand that tank overfills should be addressed in accordance with the current edition of API 2350. We aim to provide you with the expertise to address the concern for hazardous liquid overfill.

How to face the risks of overfill

One of the most significant risks at a facility that stores any large amount of hazardous liquid is an overfill event. E.g. a vapor cloud explosion can cause devastation and offend the company. Reacting to recent overfill events, the industry developed the API/ANSI Standard 2350 – a new requirement related to safety management systems.

Guidebook: best practices for overfill prevention

But how can companies implement API 2350? The purpose of this guidebook is to help you to establish a safety management system including the overfill prevention process. Learn from current best practices for overfill prevention by industry standards (like API/ANSI Standard 2350, Buncefield Report, IEC 61508 (Functional Safety) and IEC 61511 (Safety Instrumented Systems)).

Your return on investment by using an Overfill Prevention System

Tank spills happen every day generating costs of billions of dollars. Considering the benefits of an Overfill Prevention System the return of investment can be very fast even without considering the costs of damages or image that would pay off for a system immediately.

Remote, automated proof test

The remote automated Proof Tests dramatically saves time and reduces effort (from 60h down to 5min).
Instead of climbing tanks the required proof test can be performed from the control room.

Successful Tank Farm Management to increase your efficiency and safety with innovative instruments, solutions and services

Based on risk assessments and after defining the levels of concern an independent Overfill Prevention System will add the needed layer of protection to your tank farm, terminal or refinery. Beside airports, bulk storage depots and ports in the oil and gas industry also storage facilities for chemicals and hazardous fluids like ammonia in the chemical industry are equipped with systems to prevent tank spills.
Check out different use cases and learn what to consider when planning a system according API2350 and IEC61511.

Compliance and Safety Management

One main task of an Overspill Protection System is to ensure compliance to different international, national and local regulations and standards. Applying Functional Safety Management, categorizing the tanks, defining the layers of protection and calculating the levels of concern are only some steps to a compliant plant.

Increase flowrate with an Overfill Prevention System

By using an Automated Overfill Prevention System (AOPS) the reaction time is minimized. This not only allows to fill any tank to higher levels by setting the high-high level alarm (LAHH) nearer to the critical high (CH) but also enables higher flow rates for filling tanks. This safes time and money.
