SIL Compliance Dr. W. Kolb Netherlands B.V.


Recently the local governments have demanded BRZO enlisted companies, to quickly and explicitly, demonstrate and confirm, compliance to the strictest of regulations. This came as an unexpected challenge to Dr. W. Kolb Netherlands B.V. During that time the engineering team was occupied with a production expansion project and SIL knowledge was not present within Kolb. Kolb asked Stork Asset Management Consultancy to help in "dotting the i's" and support in effectively and efficiently demonstrate compliance.


Stork’s SIL experts assisted in double checking installations, procedures, documents and traceability of SIL measures. Stork’s experts in combination with the local technical team used a structured process to:

  • identify and classify safety critical issues,
  • allocate and verify equipment,
  • test, inspect and sustain measures.

Kolb has trusted Stork’s experts with support in this important task as Stork brought indepth SIL knowledge which enabled Kolb staff to focus to their core activities of maintaining production and increasing production capacity. Kolb appreciated the critical and supportive outside-in perspective of Stork in this important matter and integrated SIL in their engineering standards.
