2006-2631: Practical Design of Wharf Extension in South Carolina

Abstract Criterion 3 of ABET 2004-2005 Criteria for Accrediting Engineering Programs requires that all engineering programs seeking accreditation manifest that their graduates have an ability to “function on multidisciplinary teams.” Students should be able to serve as both a team leader and a contributing member of a design team. This paper presents a case study of one heavy marine structure in the Georgetown, South Carolina. Heavy marine structures typically involve large and unusual loads from cranes, ships, and cargo; generally are supported upon weak and sloped soils; and usually require significant design considerations for marine and coastal environments including corrosive conditions. Marine structures provide for excellent classroom case studies because they inherently require multidisciplinary evaluation and site specific engineering solutions.

Introduction This paper discusses practical design considerations for a heavy marine structure in South Carolina. As an example, it uses one project from the South Carolina State Ports Authority. The project is the extension of a commercial break bulk cargo wharf at the Georgetown Terminal in Georgetown, SC,

The South Carolina State Ports Authority (Ports Authority) operates six waterfront sites that handle containerized cargo, bulk cargo and break-bulk cargo. As a container port, Charleston generally ranks fourth in the U.S. in terms of containerized cargo volume. This is done through four terminal sites located in the Charleston, South Carolina area. The South Carolina State Ports Authority also operates two smaller bulk and break-bulk ports located in Port Royal, South Carolina and Georgetown, South Carolina.

Wharf Extension of the Georgetown Terminal The Georgetown Terminal is a dedicated breakbulk and bulk cargo facility. The top commodities are steel, salt, cement, aggregates and forest products. Pier 31 C at the Georgetown Terminal is a 500-foot wharf. Ships calling on this facility were routinely exceeding this 500 foot length and often required moving the ship to allow full access for unloading and loading cargo. These multiple ship moves increased the cost of unloading due to additional tug assist time during the multiple moves and additional time in-port to unload. To accommodate these larger ship sizes, the Ports Authority desired to extend the existing wharf from 500-feet to 600- feet.
