ExxonMobil - U.S. Non-Road Diesel Underground Project

This project won a 2009 ABC National Eagle Award for Excellence In Construction and an ABC Bayou Chapter Award of Excellence.

In early 2008, ExxonMobil broke ground on a new Non-Road Diesel Facility at the Baton Rouge Refinery.  The intent of this project was to meet new Low Sulfur Federal mandates on diesel while increasing the second largest U.S. ExxonMobil Refinery’s Non-Road Diesel production by 35%.  Through an extensive, competitive bid process, ISC was awarded the $4.4 million contract for all Underground Electrical and Instrumentation work, as well as all Temporary power for the project which spanned throughout the 2,100 acre Refinery facility.

ISC was contracted through Jacobs Field Services of North America and coordinated work activities for eleven months, concurrently with Mechanical, Civil, and other Specialty contractors to install a new Vent Stack Derrick, underground duct-banks, and temporary power services in both the ISBL (Inside Battery Limits) and OSBL (Outside Battery Limits or Offsites). ISC self-performed 100% of the scope and earned over 80,000 manhours in the process of completing this monumental undertaking.

Conduit, Wire, Lightning Protection, and FAA Aviation Lighting had to be installed on three (3) individual Sections of the over 210 foot tall Vent Stack Derrick prior to being erected. Once standing, all sections had to be connected, cables installed, and Aviation lighting operational within a 48 hour timeframe to ensure compliance with the FAA and to adequately warn air traffic in the area.

In an effort to increase reliability and minimize project congestion, ISC installed Medium Voltage, Low Voltage, and Instrument duct-banks throughout the project site. These duct-banks were as much as sixty feet wide and eighteen feet deep and had to be installed throughout the work site, around other contractors, and routed under and around existing facility piping and obstructions. As many as 200 Conduits were routed in each duct-bank. Each conduit had to be individually supported, consistently spaced and maintained at a specific elevation per the engineered specifications. Upon completion of conduit installations, each duct-bank required reinforced steel both perpendicular and parallel to the conduits, before being encased in red-dye concrete.

Temporary Power was an extensive and ongoing requirement for the project. ISC installed and maintained all of the power needs for all contractors on the project. This included power distribution from 480V to 120V service to all Office trailers, field trailers, as well as remote power to offsite work locations and even air conditioning to the contractors’ lunch facilities. With the project working both a day and night shift, ISC provided support installing temporary lighting for night work. ISC also installed new power, lighting, controls, card readers, and gate operators thereby providing a project specific entry and exit gate location. This minimized the impact of project traffic and congestion on routine facility work.

The project’s extensive Safety, Quality, and Performance requirements were a challenge for any contractor, but ISC was more than prepared to meet and exceed all expectations of the project while maintaining a zero recordables, zero lost time injuries safety record.
