Pile & Deep Foundations
Packer Avenue Marine Terminal (PAMT) – Crane Rail Extension
Location: Philadelphia, Pennsylvania • Delaware River
S. T. Hudson Engineers performed field surveys, and developed the structural design, drawings, specifications and cost estimates for approximately 600 L.F. of heavy-lift crane rail foundation. The massive reinforced concrete, pile-supported structures were engineered using state-of-the-art computer-aided design analysis and drafting software.
The work included crane and freight car rails, new water piping, and underground conduit and feeder systems for 480 volt crane parking receptacles and other electrical services.
A dust free conveyor system—also designed by Hudson—to transport fertilizer from a ship unloader to storage domes, is visible in the background.
Development of Port Crane Facilities
Location: Camden, New Jersey • Delaware River
S. T. Hudson Engineers identified client requirements and developed the performance criteria and purchase specifications for two rail mounted gantry cranes pictured above. The Kock Krane pictured above in the bottom photograph was erected at Pier 1A, a new bulk cargo unloading pier at SJPC Broadway Terminal and is a multi-purpose crane currently utilized for ship unloading of dry bulk cargoes at a maximum rate of 1,200 metric tons per hour. The crane is equipped with a clam-shell bucket, a hopper, and a belt feeder discharging to an independent belt conveyor. The crane is also capable of container handling, general cargo, and heavy lift operations.
Hudson also designed both crane rail systems including foundations and tie-downs.
Additionally, Hudson supported the acquisition of the used PACECO crane on the left of the below photograph, including the modifications to adapt it to the existing crane rail system at the Beckett Street Terminal.
Rehabilitation of the Ship Dock
Location: Marcus Hook, Pennsylvania
S. T. Hudson Engineers performed underwater inspection of the ship dock and found the ship dock required extensive repairs. A feasibility study was prepared to determine the most economical means of rehabilitating the dock while keeping the crude oil dock in service. The scope of service included federal and state permit applications, construction documents for a new approachway, mooring and breasting dolphins, walkways, loading platform and demolition of existing structures. Hudson is ensuring that the installation of temporary walkways and product piping supports, construction of a new steel pipe pile-supported concrete approachway, and partial demolition of the existing timber low deck structure was in accordance with specifications. Construction is ongoing—four (4) new steel pile-supported reinforced concrete mooring dolphins have been completed in August 2007. The complete rehabilitation of the ship dock is anticipated to be the end of 2008.
