Overfill Prevention &
SIS (API 2350)
Advanced engineering solutions for safety-critical tank terminal operations. We align your infrastructure with the latest API 2350 and IEC 61511 standards to eliminate spill risks.
Core Safety Components
Our AOPS strategy integrates hardware redundancy with rigorous risk modeling to ensure your facility maintains a robust safety lifecycle.
Safety Instrumented Systems (SIS)
Implementation of independent protection layers (IPL) specifically designed to take the process to a safe state when predetermined conditions are violated. Our SIS designs utilize high-reliability logic solvers and certified sensors.
Risk Assessment & SIL Selection
Comprehensive LOPA and SIL (Safety Integrity Level) determination for overfill scenarios. We evaluate reaction times, proof-test intervals, and architectural constraints to meet API 2350 Level 1, 2, and 3 requirements.
Periodic System Testing
Full functional proof testing of the AOPS loop, from the sensing element to the final control element (automated valves/pumps). We document bypass management and response times to ensure continuous compliance.

What is the required reaction time for an AOPS?
API 2350 requires the reaction time to be calculated based on the maximum flow rate and the available surge volume of the tank.
How do Independent Protection Layers (IPL) work?
An IPL is a device, system, or action capable of preventing a scenario from proceeding to its undesired consequence regardless of the initiating event.
Can the SIS share sensors with the basic control system?
Separation is highly recommended. A Safety Instrumented System should ideally utilize dedicated, independent sensors.
