A Marine Oil Terminal Trestle Repair and Replacement Project

This paper discusses the repair and replacement of an existing 90-yr old timber berth and trestle to meet the operational and seismic demands mandated by the marine oil terminal engineering and maintenance standards (MOTEMS). Many older marine oil terminals in California have been required to meet the MOTEMS regulations. However, many operators are looking for innovative ways to achieve the regulation requirements with restricted capital budgets. This terminal meets the MOTEMS requirements and capital constraints by replacing and repairing portions of the trestle. The strengthened structures meet the present demands for operational and seismic conditions as well as climate change issues. The author and his colleagues have recently completed the design and permitting of the first timber structure in the San Francisco bay area that includes operational, seismic, and sea level impact design requirements. The paper discusses the geotechnical and operational constraints, design criteria, permitting coordination, climate change adaptive measures, instrumentation requirements, early construction issues, and path forward for future waterfront structures. This paper also discusses the various alternative replacement and repair designs, the selection of the most cost effective options, lessons learned and some pitfalls to avoid for future rehabilitation projects.
