Gerwick and Ocean and Ocean and Coastal Consultants, Inc. were retained to provide professional engineering services related to a MOTEMS audit. Services included an above-water inspection, mooring and berthing analysis, and a structural analysis of the wharf to determine its operational adequacy. Based on the results of the inspections and analyses, recommendations for repair programs were made.

The structural underwater inspections were conducted under the direction of a registered Professional Engineer-Diver who actively participated in the inspection by personally conducting a least 25 percent of the underwater examination. Each underwater team member was a commercially-trained diver or equivalent. Following the ASCE Underwater Investigations Standard Practice Manual, the underwater structural inspection included a Level I, Level II, and Level III inspection effort. A Level I effort, or visual examination, was completed on 100 percent of the structure to confirm the continuity of the full length of all members and to detect undermining or exposure of normally buried elements.

Following the inspection, a structural engineering analysis was performed, which incorporated the current condition of members. This included a mooring analysis of Panamax and Aframax oil tankers using OPTIMOOR. To determine the structural adequacy, a finite element model of the entire berth was created and demands were compared to calculated capacities based on the current California Building Code. The results of this analysis allowed Gerwick to provide our client with a recommended path forward for repairs.
