Presentation – ISA Process Control & Safety Symposium 2015 Houston

“Automation Infrastructure Upgrades at an Oil Storage Terminal”

This paper discusses the approach taken to upgrade the automation infrastructure at an existing oil storage terminal comprising pipeline reception as well as truck and tank car loading bays. The project aimed at replacing obsolete components and subsystems with newer technology equipment, while improving site safety and security. A description of the various control subsystems involved and their interaction with the process equipment is provided. The project included the relocation of the main control room as well as upgrades of the power distribution and control systems. Compliance review with various standards and regulations is also discussed. The HMI software and PLC hardware were both obsolete. The article describes their modernization and implementation based on a Programmable Automation Controller (PAC) combined with a standard library of faceplates and standard routines for pumps, valves and process instruments. In addition, the paper discusses the implementation of a redundant overfill protection system as per API-2350, as well as a Safety Instrumented System (SIS) as per ISA-84/IEC 61511, integrated with the basic process control system (BPCS PLC) and HMI. The paper discusses the various measures taken by the team to reduce downtime associated with the project execution, taking into account the dynamic product demand and equipment availability. This included planning and communication on multiple fronts throughout the project. The conclusion summarizes what made the project a success.
