Project Scope The Fauna Fire Water System FEED study was completed to determine the design perimeters and equipment necessary to reduce the risk of multiple tank fires due to radiant heat from an adjacent tank fire if one was to occur. Excellence was tasked with determining which tanks are at risk and to prepare options…

Project Scope Excellence Engineering provides Facility GAP Analysis to clients in order to identify NFPA 70 (NEC), Article 501 (liquids and vapors) and Article 502 (dusts) code deficiencies in relation to the defined electrical area hazardous classification of petrochemical and oil & gas related facilities.  This type of analysis is beneficial in both new and…

Project Scope Excellence Engineering provides hazardous area classification studies for petrochemical, refinery, midstream and all other oil & gas related facilities.  The purpose of the Hazardous Area Classification Study is to define the hazardous area for the installation of mechanical, electrical and control system equipment.  The analysis is performed utilizing the facility material balance, process…

Project Scope Addition of two 70,000 BBL IFR crude oil storage tanks at the Hess Tioga Rail Loading facility.   Civil, mechanical, and electrical engineering design, programming, and commissioning.  Project included piping, electrical, instrumentation, automation, and fire water and foam systems. Notable Accomplishments & Challenges Upgraded existing fire systems and seamlessly integrated  upgraded  automation and control…

Project Scope The Hess Tioga NGL rail loading facility is a 16-spot rail loading rack on a spur of the Tioga crude rail loop.  It loads propane, butane, and natural gasoline produced and fractionated at the Tioga Gas Plant located 3 miles away.  Loading rack is connected to the plant outlet by 8” and 6”…

Project Scope HollyFrontier’s Truck Loading project in Tulsa, Oklahoma implemented an additional means of removing heavy gas oils (HVGO) from storage tank 188 in order to supplement the existing piping discharge. The project added a single truck loading spot with a 15HP/460V product transfer pump, truck grounding monitor, local pump control station and ESD, local…

Project Scope The objective of the J-50 Wet Gas Compressor Starter Replacement Project was to replace the obsolete and antiquated 13.8kV, 5600HP reduced voltage reactor starter used to start and run the wet gas compressor of HollyFrontier’s fluid catalytic cracking unit (FCCU).  Replacement components for the existing Westinghouse air-break circuit breakers and starting reactor that…

Project Scope The Substation 2 Mechanical Relay Replacement Project was initiated to replace two antiquated oil-immersed 2300V circuit breaker switchboard control panels at the HollyFrontier Refinery West Plant. The location of the switchboard panels inside the substation had become a concern due to the potential arc flash hazard to refinery personnel from the overhead open…

Project Scope The group of projects were executed to bring compressor station upgrade projects into compliance with NFPA 70E. Excellence provided a field survey to gather site information to analyze the installed electrical system which included circuit breakers, motor starters, panelboards, motor control centers, transformers, feeder and incoming line cables, and other wire and cable…

Project Scope Magellan Midstream’s Albany facility was upgraded to increase the storage capacity of gasoline, increase the throughput of the existing truck rack, and to provide blending capabilities to the terminal. A new 100,000 barrel tank was added to increase the storage capacity of the terminal. Three new pumps were added to the existing system…
