Representative Projects: Marine Structures :

Cemex Redwood City Marine Terminal - The project included a cement marine off-loading terminal, and an electrical distribution station. The project also included dredging the berth area to Elevation –37 feet (MLLW), cutting back the existing shoreline slopes to accommodate the planned dredge depths; providing shore protection against wave act; providing breasting dolphins consisting of 60-inch diameter monopiles; and several concrete-pile-supported mooring dolphins.

A pile-supported conveyance system is used to transport cement materials from the off loading platform to the on-shore facilities.  The unloading equipment is installed on a fixed platform and during unloading operations the vessel is moved axially along the berth to position the bulk cargo holds.

For the marine terminal, Hultgren – Tillis Engineers reviewed existing data and explored subsurface conditions using barge-mounted drilling equipment and cone penetration testing. Hultgren – Tillis Engineers provided geotechnical design criteria for each of the project elements, including assessing safe cut slope inclinations along the shoreline and axial and lateral capacities of concrete and steel piles for foundations and mooring systems
