Description:

Augusta Engineering & Design, Inc. and MEC Construction partnered in this design/ build turn-key project at Dominion Transmission’s Cove Point facility to design and install two 5,000 HP air separation units and a gas turbine generator.

Also included in the project were a main turbine building design, two substation designs, a 770 kw emergency generator, duct bank system, and a DCS control system.

The installation will double Cove Point’s storage capacity. Augusta’s scope of work included the engineering, design, commissioning and installation oversight of instrumentation and controls for the two nitrogen plants and electrical support facilities.

The 20, 000 HP Solar Titan Turbine Generator set will supply 13 megawatt, 13,800 volts to the two new 12 MMscfd Air Separation Units.

The gas turbine fuel gas preparation portion of the project includes (1) a filtration-coalescing step to remove particulates and liquids, (2) gas pre-heating, and (3) pressure regulation to meet the turbine’s fuel specifications.

Commissioning and start-up is September 2007, with an in service date of January 2008.
