Abstract:

Bulk Dock 2 at the Port of Corpus Christi is an export terminal for dry bulk materials including petroleum coke. The bulk materials are loaded onto moored vessels using a radial ship loader that operates on a turntable. The primary structure of the ship loader is two structural steel plate girders, which are 11.5 feet deep and have an overall length of approximately 211 feet. A shuttle and boom assembly moves along rails on the girders to extend and retract the boom during vessel loading. During a rail replacement project in early 2022, corrosion-induced section loss was observed on the top flanges of both girders, raising questions regarding the possibility of increased stresses in the girders and reduced fatigue life. Due to a lack of documentation on girder loading due to shuttle/boom movement and bulk material during operations, an evaluation approach was developed involving instrumentation of the girders to measure the distribution of stress amplitudes and cycles during vessel loading events. The sensor data were compared to structural models and used to calculate the remaining fatigue life of the girders accounting for the corrosion section loss. The presentation will summarize investigation approach and present findings of the girder fatigue evaluation using the measured strain response.
