Marathon Petroleum extended another opportunity to MJW Consolidated construction team to showcase our diversity, flexibility and capability to perform multi-craft scopes with 100% in-house staff, by awarding us the Jacksonville Terminal VCS Improvement project. This predominantly electrical system upgrade project includes new 480 volt 500 Amp feeder from the existing automatic transfer switch to the new, pre-fabricated building, containing the motor control centers, transformers, variable frequency drives, distribution and control panels.  The new VCS will include five new motors controlled by variable frequency drives and three new motors controlled by full voltage non-reversing motor starters.  Two vapor control cabinets, supplied by the owner, will be installed by MJW and will include a new fiber optic network that will interface with the existing network.  The project has over one mile of galvanized rigid conduit ranging from 3/4” to 4” and five miles of copper cabling.

The project begins in April and will be completed in August 2016. The project has a complex phasing schedule due to the requirements of maintaining the existing VCS in an operational state until the construction of the new VRU, VCU and bladder tank system is complete and operational.  The work will be performed by multiple disciplines within MJW Consolidated and coordinated carefully with our client, our suppliers, our manufacturers, the EPA and the City of Jacksonville.
