P2S was selected to serve as electrical engineer for the strategic redevelopment, expansion, and modernization of the terminals that comprise the “Middle Harbor” area at the Port of Long Beach in California. P2S is responsible for the engineering, design and construction administration for the project, which will span 14 years.
The Port’s middle harbor container shipping terminals were old and outdated—designed for a past era of containerized shipping. To improve efficiency and meet current 21st century environmental standards, they had to be updated. This would allow the Port of Long Beach not only the opportunity to utilize new technologies, it would also allow for infrastructure upgrades that would improve the environment. As a result, once completed, the power infrastructure will have the capacity to fully support not only typical terminal needs (medium voltage quay cranes, site lighting, and building distribution), but also “greener” port technologies such as shore-to-ship power and electrified rail-mounted gantry cranes in the container yard.
P2S designed a reliable distribution system to serve present and future needs for the Middle Harbor. The completed mega-terminal will be served by a 112 MVA, 66-12 kV substation that will be constructed in stages over the next ten years.
The terminal also includes:
- 12kV intermodal yard substation
- (3) 6.6kV shore power substations
- (10) 480V reefer substations
- Site distribution to facilitate power and communications to medium voltage quay and stacker -cranes, shore power outlets, reefer outlets, terminal site lighting and buildings
- State-of-the-art energy and power management solution for managing the increased demands of the electrified terminal
P2S is also advancing and standardizing shore-to-ship power solutions by leading the development of an international IEC/ISO/IEEE standard for shore-to-ship power. This ensures that the shore-to-ship power system at the Middle Harbor is state-of-the-art. It will also serve as an example for other terminals nationwide to follow.
The mega-terminal will be served by a distribution system designed for a minimum 40-year life and will meet the anticipated needs of an automated, electrified terminal while allowing flexibility for future reconfiguration of loads.
The redevelopment project will reduce air pollution significantly from port-related operations at the terminals. The aggressive environmental measures contained in the Green Port Policy and San Pedro Bay Ports Clean Air Action Plan are designed to reduce air pollution by 50 percent or more and cut associated health risks even with the maximum projected growth in trade.
