IPL Lifecycle Support

A Process Safety Management Company

We are Provenance Consulting

We remain true to the same principles on which our company was founded over ten years ago: providing superior service to our clients, putting safety first, creating opportunities for our people!

IPL Lifecycle Support

From the moment in a PHA when credit is taken for a safeguard as in Independent Protection Layer (IPL), throughout the documentation effort and during the ongoing visual inspection and proof testing process, Provenance Consulting provides support for IPL-related tasks that are required throughout the IPL lifecycle.

Our services are designed to ensure compliance with industry, corporate and facility requirements, ensuring that the work processes and project deliverables incorporated into our client’s systems are reflective of industry best practices, corporate standards, and site procedures.

The Process

Our Approach

Our success is due to our understanding of not only the IPL lifecycle, but of the contributing and dependent systems, processes, and decisions that influence each IPL.

This comprehensive approach ensures that our processes are efficient, deliverables are robust, and the resulting management systems are effective and easily maintained.


Managing the entire lifecycle of Independent Protection Layers will ensure effectiveness, auditability and independence.
