CONTRIBUTION TO THE DETERMINATION OF THE SILs REQUIRED FOR THE SAFETY OF PETROLEUM INSTALLATIONS: CASE STUDY OF THE PROPANE STORAGE TANK (BALLOON)

Sidali BACHA, Rachid CHAIB, Ahmed BELLAOUAR

Abstract


Petroleum thermohydraulic systems are high-risk facilities whose analytical methods such as HAZOP can be applied as a risk analysis tool. However, this type of method is used to qualitatively indicate the existence of security barriers or to treat them in a dependent manner without taking into account the notion of independence between safety barriers. In this article, the semi-quantitative LOPA (Layer of Protection Analysis) method was applied to a propane storage tank (V306) in order to identify the scenarios that present a high risk by clearly indicating the level of safety integrity (SIL) required to ensure tolerable safety. The SIL will also be assessed by the "Risk Graph" method, which allows us to exploit expert opinions and compare its results with those obtained by the LOPA method. The independent protection layers (IPLs) evaluated as well as the Safety Instrumented System (SIS) proposed for the propane storage tank refer to the functional safety standards IEC 61508 and IEC 61511.
