Global Coatings Manufacturer
Design, installation and commissioning of high-level protection systems for bulk solvent storage facilities
A global manufacturer of decorative coatings needed to upgrade existing high-level protection systems on a number of bulk storage facilities on one of its upper tier COMAH sites in the UK. The materials were classified as flammable and dangerous to the environment.
Safe and compliant design
The UK regulator places much emphasis on adherence to recognised standards and good practice guidance to demonstrate compliance with key process safety legislation such as COMAH and DSEAR.
Safety Instrumented Systems (SISs) used as Independent Protection Layers (IPLs) to avoid major accident hazards must be suitably designed, installed and tested to ensure that the required Safety Integrity Levels (SILs) are maintained.
The relevant standards (BS EN 61508 and BS EN 61511) refer to a Functional Safety Lifecycle approach that must be followed. The client would need to demonstrate compliance with these and other relevant standards for SISs in potentially explosive atmospheres.
Meeting the requirements of BS EN 61511 for compliance with COMAH
SIF definition, SIL determination and SIS design and installation
Providing a team comprising process safety professionals and TUV certified engineers, we could define the Safety Instrumented Functions (SIFs), determine target SILs, develop and validate SIS designs against the target SILs, and install and commission the new systems, preparing essential documentation for ongoing inspection, functional testing and maintenance.
COMAH and ATEX / DSEAR
Guidance and support in relation to Functional Safety and the relevant standards for compliance with COMAH and ATEX / DSEAR.
HAZID and LOPA / SIL Determination
Conducted a Hazard Identification Study and Layers of Protection Analysis (LOPA) to assess the risk reduction measures needed to prevent overfill and determine the required SILs for the high-level protection systems (SIS), all in accordance with the standards
In accordance with the Functional Safety Lifecycle specified in BS EN 61511, developed the Safety Requirements Specification (SRS), Functional Design Specification (FDS), and loop designs. The systems were then installed and commissioned, and assessed in accordance with the standard.
Providing a team comprising process safety professionals and TUV certified engineers, we could deliver:
Our understanding of process safety and environmental legislation, together with our knowledge of the relevant standards for specification, design, installation, commissioning and testing of Safety Instrumented Systems allowed our client to meet their obligations under COMAH without introducing unnecessary complexity or cost.
