Completed in 2013


The Shell Refinery and Petrochemical Plant in Deer Park, Texas began the Hazards and Effects Management Process (HEMP) Tank Overfill and Reliability Project to update technology and increase the safety of its product holding tanks throughout the facility. HEMP is a systematic method used by Shell to identify hazards, assess and mitigate risk, and establish recovery measures.

As an electrical and instrumentation (E&I) leader in the industry, Shell Deer Park turned to ISC and entrusted them with 100% of the E&I construction. ISC was able to assist Shell Deer Park in the first phase of its tank level monitoring upgrades by bringing the confidence and experience needed to safely and accurately install them. ISC worked with Shell operators to design a method to analyze the accuracy of the new readings by aligning old and new instruments so that readings could be read in parallel.
