MJW to Perform Electrical Installation for Sunoco Fuel Blending System // May 2017

Sunoco LP has chosen MJW Consolidated to install electrical systems and instrumentation for a proprietary liquefied petroleum gas (LPG) blending system at an existing Phillips 66 fuel storage terminal in Mount Vernon, MO.

Work on the project will begin in late June and is expected to be completed in about three months, said MJW project manager Mike Greene. “This is the fourth project of this type we have been awarded by Sunoco, which owns the technology,” Greene said.

The Sunoco system adds butane to stored LPG before the fuel is loaded onto tanker trucks. Butane is a standard additive in gasoline, but it dissipates over time and must be brought up to target levels before the fuel is transported for commercial sale. In addition to injecting butane into the LPG, the blending system measures, samples and tests the fuel.

Understanding the fuel storage terminal environment and providing outstanding service are essential requirements for working safely and efficiently at major fuel storage facilities. The MJW electrical installations team has successfully performed similar projects for Sunoco at terminals in Florida, Texas and Georgia.

HVAC Upgrades Ensure Greater Efficiency for Savannah Post Office // April 2017

Energy efficiency is an important priority at U.S. government facilities, but so is serving the public.  MJW Consolidated recently helped the main U.S. Post Office in Savannah, GA accomplish both objectives by completing a major upgrade of the facility’s heating, ventilation and air conditioning (HVAC) systems without disrupting operations.

The 10-month project completed in early 2017 involved replacement of outdated equipment with high-efficiency systems, including two boilers, two chillers, five air handlers and all of the associated pumps and controls. MJW self-performed most of the work and subcontracted with Johnson Controls on system controllers.


The modern boilers save energy through greatly reduced environmental heat loss, the chillers are driven by compressors that use magnetic fields to reduce motor friction, and the new pumps are equipped with variable frequency drives that adjust automatically to demand loads. These advanced features and many others will result in significant energy savings for the 1950s-era facility.

In addition to serving as the main mail distribution center for Savannah, the facility provides lobby service to postal customers.

“Completing the project while allowing the facility to continue performing its vital role in sorting and distributing mail, as well as serving the public, was vital to the client and to us,” said MJW project manager Ralph Harrison. “Our project supervisor, Wade Douglas, myself and the entire team worked closely with the post office staff to ensure safety and continuity of operations."
