Crow Engineering, Inc. was contracted to perform a structural assessment of the California Redwood Company chip loading facility adjacent to the Evergreen Pulp Mill in Samoa, California.
The dock structure consists of the combination of a timber pile finger dock which extends approximately 700 feet over the water, a timber pile supported central platform, and a steel pipe pile supported concrete deck and pile caps which support the main town structure.
The conveyor is supported on four timber bents utilizing full height timber piles and four steel bents that are supported by concrete pile caps on steel pipe piles. Additionally, a series of steel pipe pile dolphins with concrete caps, connected by a timber walkway extend both directions from the main dock structure, including one timber dolphin on the south extension.
Crow Engineering provided the project engineering and conveyor system design on chip plant modifications and a new ship loading facility installation. The goal was to increase the chip-loading rate from 400 TPH to 1200 TPH without causing any additional chip discharge to the waterway.
The capacity of the existing reclaim conveyor was increased by threefold. A new 60″ wide conveyor (86 feet tall and 430 feet long) was installed to convert the system from a “long-blow” system to a “short-blow” system. A new tower with a ship-loading boom was installed on a new marine foundation.
During Phase 2, Crow Engineering was hired to design a state-of-the-art barge unloading system including the “Slave Barge,” onboard chip reclaim conveyor and transition conveyor, new articulating conveyor to dock, 250 feet long dock-supported chip conveyor, and rotary stacker for pile creation.
