Project Overview
The Challenge
The main objective of this terminal is to receive aggregates from Vancouver Island, British Columbia via handymax and panamax-sized self-unloading ships. Aggregate-delivering ships berth at Berth 22, where they unload aggregate into a ship-unloading hopper.
A series of conveyors then transport the aggregates from the hopper to stockpiles located on the project site, with three distinct stockpiles. Reclaim conveyance was added to transport aggregate from the stockpiles to the dock, where barges can be loaded to distribute aggregates to customers. Aggregate in the stockpiles can also be shipped to customers via trucks that are loaded using ground equipment.
Our Approach
The Solution
The electrical and control system design included replacement of onsite PG&E electrical service equipment with new customer-owned transformers and switchgears. The motor control and automation systems are designed into mobile electrical structures that will be fully assembled and tested offsite prior to commissioning.
The site lighting design utilizes Port standard lighting equipment that will be controlled by the facility owner's SCADA system via wireless communications. All sensitive electrical equipment will be housed inside one of the modular electrical enclosures.
Each product transfer site is monitored by the site CCTV system, as are the incoming and outgoing truck scales. The site is covered with Wi-Fi, allowing mobile equipment operators to control all operations from the cab of their loaders.
Results
Project Outcomes
The Oakland Aggregate Terminal delivers a fully integrated electrical and controls solution for the efficient receiving, stockpiling, and distribution of aggregates at the Port of Oakland. The system combines SCADA-controlled conveyors, wireless communications, CCTV monitoring, and Wi-Fi-enabled mobile operations into a cohesive, modern terminal operation.
