● Participated in Inspection Data Management System gap analysis to anticipate and mitigate issues that may threaten the integrity of fixed equipment asset strategy (FEAS) program. ● Facilitated Light Detection and Ranging (LIDAR) program under FEAS project. Estimated $2MM saving from the traditional FEAS workflow. ● Coordinated laser scan activities with Capital Project and Light Tight Oil (LTO) groups in Pasadena, reduced duplicate scanning work in the field with estimated saving of $250M.● Supported refinery Digital Twin effort utilizing the laser scan deliverable from FEAS project, cooperated with ETC to pilot a laser scan viewer on site with an estimated future saving of $1MM associated with improved work efficiency. ● Executed MPT calculation for (25) critical equipment in DHT, NHT and LPG unit per Chevron guidance. Collaborated with Process and Materials group to address MPT violating issues by updating the operating procedures.● Assisted in 2020 Design Engineering group during Reformer Turnaround by answering more than 10 RFIs within desired response time.● Conducted technical review on capital project heat exchanger purchase and approved a nozzle size increase following Chevron standards to address dissimilar metal weld joint concern.

● Piloted new coating system in Pasadena on a storage tank adjacent to cooling tower where a full enclosure would be required for conventional coating system. Estimated $30K saving from eliminating the scaffold needs. ● Performed Caesar II model analysis to resolve the overstress issue with FCC Catalyst yield line revision project, which improved the operator safety where they can operate the valves away from a hot and confined area. ● Led collaborative effort between ETC refractory SME and site contractor during FCC 3rd stage separator inlet line repair, and facilitated the repair to meet Chevron standard based on operating condition. ● Provided torque calculation and gasket selection using Chevron tool for (10+) equipment for maintenance job packages.● Developed technical specification for equipment requisitions, minimized cost increase from change orders. Aligned with the latest industry and Chevron standards.Fixed equipment integrity improvement
