Our Experience

Odfjell Terminals Charleston Site Development

GEL assisted Odfjell Terminals with the design, permitting and construction of their second marine terminal in the United States.

The Client

Odfjell Terminals (Charleston) LLC is a premier distribution terminal serving the bulk liquid and specialty chemical, vegetable oil and petroleum industry in the southeastern United States.

The Challenge

The facility will receive, store and transfer liquid products for Odfjell’s customers. These products will arrive at the terminal by ship, barge, tank truck, and rail car.  The products will be stored in aboveground tanks, and then transferred to outbound vessels and over the road carriers of the same type. The facility will consist of ship/barge/truck/rail car loading racks, approximately 34 aboveground storage tanks, a boiler, an enclosed flare, and other emission control equipment.  

Odfjell chose a 20 acre site on the Cooper River in North Charleston, SC as their new storage facility.  The site is relatively long and narrow and site layout was challenging.  In addition to the tanks containing 500,000 BBL of storage capacity, a truck scale building, wastewater treatment system and five (5) new rail sidings had to be placed on the site. These facilities, along with administrative and operational buildings were placed strategically while maintaining truck access through the entire site.  To add to the challenge, a one (1) acre +/- grove of large oak trees thrives on the site and the local community required the trees remain without damage.

GEL Engineering Services Provided
  • Obtained a Joint Permit from the United States Army Corps of Engineers (Corps) and South Carolina Department of Health and Environmental Control (SCDHEC) for the construction of new waterfront improvements, including dredging of the berth. A dredge sediment sampling and analysis plan was prepared, submitted, and executed in order to obtain approval for dredging and disposal of the dredged sediments in nearby dredge disposal facilities.
  • Obtained all applicable environmental permits for a marine facility adjacent to the Cooper River.
  • Performed industrial hygiene inspections to identify lead-based paint and asbestos containing materials associated with legacy landside structures slated for demolition and/or renovation.
  • On-going coordination with applicable regulatory agencies (county, state, and federal) to review operations and discuss required revisions to environmental permits, including expedited processing and approval of the permit applications.
  • Performed wetlands surveys and delineation for the site. Coordinated with the South Carolina Department of Health and Environmental Control (SCDHEC)  and the US Army Corps of Engineers (USACE) to obtain a critical area/Jurisdictional Determination for the site.
