Work History
Superintendent, Maintenance Reliability, 09/2019 to Current Cargill, Inc. – New York, NY,
Responsible for re-establishing focus on refinery reliability efforts with emphasis on rotating equipment.
Led creation of vibration program for Wilmington and Carson refineries. Overhauled SKF Aptitude analyst software (vibration analysis software) to include all pumps. Routes were built with frequencies based on equipment criticality and failure history. Collaboration with Operations to ensure pump switching allowed for data collection on spared equipment. Compliance reports produced and circulated for visibility and accountability. Several machinery issues have been discovered on spared equipment as a result of this new approach.
Implemented Return to Service Policy and Procedure that requires maintenance standby for rotating equipment startup after repair. A tag is used as a visible reminder to contact maintenance on startup. A tag log shows compliance for accountability. This program has resulted in several shutdowns immediately on startup due to vibration concerns.
Led our site as the pilot in the implementation of APM (Asset Performance Management) reliability software. Led and coordinated with several departments and disciplines on deployment and training. Started renewing criticality for rotating equipment as a priority. I've advocated for improvements to APM and helped build and refine dashboards and queries for use throughout Phillips 66.
Responsible for successful closure of 3 CUPA (Certified Unified Program Agencies) action items associated with a crude unit fire in 2019. I updated our daily maintenance work flow process along with several actions we took for addressing high priority notifications. I was able to show compliance with a second action item using the data collected with the new vibration program on the pumps which were the source of the 2019 fire. And a third action item was closed by showing compliance with the newly implemented return to service procedure.
Renewed focus on site bad actors with emphasis on centrifugal and recip compressors. Successfully improved the reliability of our hydrogen plant feed compressors after finding the cause of several discharge valve failures was process gas condensing in 2nd stage cylinder. Jacket water temperature adjustments were made along with valve upgrades to allow for more tolerance to liquids. Currently working to implement solution to chronic bearing failure history on the recycle gas compressor at a reformer unit. Discovered poor vacuum in seal gland condenser leading to excessive moisture in oil due to turbine steam leaks. Currently building scope to address that and several potential causes to poor bearing life.
Bulk Utilities Engineer and Process Supervisor, 09/2017 to 06/2019 Phillip 66 – City, STATE,
Responsible for ensuring reliable operation of Buik Utilites areas with emphasis on Boiler Plant which was at reduced capacity.
I helped increase boiler plant capacity by reducing excess air, diagnosing and recommending repair of a forced draft fan and an air preheater. These actions improved the boiler plant steam capacity from 585 to 650 MPPH. Additional recommendations were made for burner replacement on another boiler due to high CO production limiting the capacity. This is being implemented in 2021.
Improved reliability of DAF (Dissolved Air Flotation) units and API separators by working with Nalco on optimizing chemical injection and improving our air diffusion. This along with better operator training allowed us to extend the turnaround cycle on each of these vessels by one year for a savings of $300K yearly.
Implemented monitoring tools and changes to logic to improve well water production which helped reduce the cost of city water by $500K in 2017 compared to 2016.
Added SCR catalyst replacement to Cogen turnaround scope after identifying that additional back-pressure in our existing catalyst was the cause of high heat at the exhaust bearing due to reversal of cooling air flow during shutdowns. Implemented a new procedure to ensure cleanup efforts inside the exhaust section and updated differential pressure alarms to mitigate future failures.
Reviewed our plant air quality after several unit upsets due to water in instrument air. Prepared scope of work and actions for our air dryers including desiccant replacement, valve servicing, heat exchanger leak repair, and addition of dew point as a key performance indicator for better future tracking of air quality. Dew point was reduced by ~50F after actions completed.
Bulk Transfer Engineer, 06/2014 to 09/2015 Phillips 66 – City, STATE,
Responsible for ensuring reliable operation of the Bulk Transfer units including product transfers within and outside the refinery.
Executed plans to deal with high Naphtha inventories during and unplanned reformer shutdown to prevent additional unit slowdowns including executing an H2S scavenger treatment plan for Naphtha to allow for shipping out through our marine terminal.
Implemented a process to track recovered oil produced by process units to better understand and resolve high volumes to tankage causing high inventory levels and upset to unit operations.
Was the operations lead to upgrade the DCS for Bulk Transfer including a FAT test offsite. This included revising all tank level alarms to mitigate the potential for overflows and tank damage.
Reliability Engineer, 06/2009 to 06/2014 Phillips 66 – City, STATE,
Responsible for the reliability of rotating equipment at the Wilmington Phillips 66 site.
I collaborated with Operations personnel to create bad actor lists and worked to implement solutions to recommendations.
Provided turnaround work scopes for critical rotating equipment including for a super major turnaround including the FCC and Alky units.
After high temperature and vibration issues caused an unplanned shutdown of the Cogen Gas Turbine I was responsible for overseeing the overhaul which included bidding work, expediting parts, and overseeing the field execution.
Improved the MTBF of the recip compressor fleet at Wilmington by working with OEMs and vendors to understand and resolve valve and piston failures on several critical equipment.
