Infinity was the prime consultant responsible for all structural, civil, mechanical, and electrical designs associated with the design and construction of a new ship and barge dock at IMTT’s Geismar Terminal. IMTT sought to expand the dock capacity on the river for a new liquid terminal by establishing a new ship and barge dock immediately upstream of an existing dock.
Infinity designed the new dock, located on the Mississippi River, in line with the current dock such that the two will have one common fenderline. The dock itself is a small rectangular deck area with a hose tower on top. Flanking the dock are independent breasting and mooring dolphins for both barges and ships. The dock is fed by a new pipe rack and walkway that tie into the existing rack just behind the existing dock.
The electrical designs included new electrical power and control systems to tie into existing electrical power and SCADA systems at the previous terminal facility. The project included the extension of the existing 480 Volt, 3 Phase power distribution system to a new Motor Control Center in a new dock house building, extension of existing single-mode and multi-mode fiber optic DCS, SIS, and plant data systems to the new dock house, power for new telemetry controlled hose tower crane, power and controls for safety shut down systems, site lighting, control stations, grounding, wastewater level control systems, navigation lighting, instrumentation for pumping operations and safety systems.
The dock services ships up to perhaps 650 feet in length with no more than 45 feet of draft, as well as river barges. The project has been permitted by the U.S. Army Corps of Engineers for this purpose.
