SELECTED PERSONAL ACHIEVEMENTS




Reduced out-of-service pumps by 60%, rework by 80%, increased Mean Time Between Failure 20%,
reduced lost production opportunity (due to rotating equipment failures) by $1,800,000 per year.
Initiated and led Failure Modes & Effects Analysis on an entire production unit that was experiencing
unusually low on-stream time of 55% for 2-3 months. My team’s analysis was completed in 10 days;
our 155 recommendations restored on-stream time to 94% within 2 mos.
Planned and directed a month long turnaround, completed 6 days early despite a 25% change in scope
due to discovery work. I also monitored daily progress of the critical path refurbishment of a copper
distillation tower at a 3rd party shop and wrote a 30 page technical report on this.
Developed a grass roots vibration monitoring program, performed analysis. Data driven
recommendations on a 700 hp and a 1000 hp motor avoided $2,000,000 in lost production.

LYONDELLBASELL
Oct 2005 – August 2009
Principal Machinery Engineer, Channelview, Texas
Oct 2008 to August 2009
Responsible for performing root cause failure analysis, recommending improvements, and providing technical
support for repairs of 700 pieces of machinery for an MTBE unit (32K barrels/day), Butanediol unit (134MM
lbs/year), Polyols unit (565MM lb/yr) and Utilities unit (1.8 MM lbs/hr steam).
 Lead Pump Improvement Team, identified $502K/yr in improvement opportunities.
 Eliminated $400K in seal failures on production critical pump by correcting mechanical run outs in the
pump, modifying the seal face profiles, eliminating contaminants in the seal support system, and
addressing quality control problems at the seal vendor’s repair facility.
 Led Utilities PM Optimization effort on rotating equipment and boiler instrumentation. Consolidated
700 separate PM tasks into one event, improving manpower utilization by 50%. This effort also
ensured that all safety critical PM’s (turbine overspeed tests) on forced draft fans were completed
without requiring additional boiler outages.
 Developed overhaul procedure for diaphragm metering pump. This solved a 5 year old reliability
problem on an environmentally critical pump, MTBF improved from 1 week to 1 year running.
Senior Mechanical Maintenance Engineer, Channelview, Texas
Oct 2005 – Oct 2008
Responsible for support of rotating/stationary equipment repairs, including 1,400 pieces of rotating equipment
in two 600MM lb/yr propylene oxide/styrene monomer plants. Responsible for mentoring co-op and new
graduate engineers.
 Performed root cause investigation of failure of 5,100 hp steam turbine. This included overseeing a 3rd
party fluid dynamics analysis and finite element analysis of the turbine nozzles and blades. This
failure cost the company $4MM. Presented the findings to the Senior Vice President of Lyondell.
 Reduced out-of-service pumps by 60%, rework by 80%, increased MTBF 20% by leading spare parts
reviews, conducting root cause analyses, and promoting best maintenance practices for pump repairs.
 Implemented steam trap maintenance program including workflow procedures, saving $1MM/yr in
steam losses and turbine damage.
 Eliminated repeat seal failures of 600 hp pump in 430 degree benzene service. This had resulted in
$300K in maintenance costs, 4 reportable environmental incidents, and 2 emergency responses.
 Developed Maintenance Engineer Toolbox – this is a website developed for the LyondellBasell
intranet to help maintenance engineers identify technical tools and resources to help them carry out
their daily duties.

BASELL POLYOLEFINS
July 2001 – Oct 2005
Senior Mechanical Reliability Engineer, Bayport, Texas
Responsible for support of rotating/stationary equipment repairs in 170Klbs/hr polypropylene manufacturing
facility.
 Chaired Predictive Maintenance Committee, back-up to Maintenance Manager.
 Led Failure Modes & Effects Analysis on an entire production unit. This unit was experiencing
unusually low on-stream time of 50-55% for 2-3 months. Our emergency analysis was completed in
10 days and the team’s 155 findings and recommendations restored on-stream time to 94% within 1-2
months.
 Led Root Cause Analysis of catalyst metering cylinder failures. Changes to the piston seal design and
a system flushing procedure increased MTBF from 10 days to 1 year.
 Led Root Cause Failure Analysis of Aerzen screw compressor failures on pellet conveyor system.
Previously there had been 155 trips of the conveying system over 5 years and several shutdowns of a
100K lbs/hr extruder. By identifying several malfunctioning control valves and limit switches, we
eliminated this and $400K in repair expense and rental equipment costs.
 Analysis of Sundyne and Sunflo pump failures reduced maintenance costs and downtime by 75%.
Problems included gearbox foaming, seal leaks, shaft failures, and chronic vibration.
 Reduced trips of Ingersoll Rand Centac instrument air compressors, from once/week to once/year.
Identified intercooler fouling and condensate trap failures as the source of impeller damage,
compressor surge, and shutdowns from high temperature.

capital project management and development and management of vibration monitoring programs.
 Expanded the vibration monitoring program by 300% and gained approval to obtain a dedicated hand
held analyzer for the site.
 Designed and installed a $200K hazardous powdered additive handling project. This eliminated
exposure of employees to hazardous phosphorous pentaoxide dust.

EVAL COMPANY OF AMERICA
April 1994 – April 2000
Maintenance Engineer, Pasadena, Texas
Responsible for support of mechanical maintenance of 3 barrier resins units, small project management.


This was a sold-out specialty resin unit, of which we were 1 of 2 manufacturers in the world. We were
able to keep the plant running at 99% reliability & deliver product when our competitor couldn't.
Responsible for turnaround planning, scheduling, and execution. Planned and directed 2 major
turnarounds, injury free. The largest turnaround, 1 month in duration, included tie-ins for a new
production line that we were building. By building contingencies into the plan, it was completed 6
days early despite a 25% change in scope due to discovery work. During this turnaround, I monitored
daily progress at a 3rd party shop of refurbishment of a 135 ft copper distillation tower and wrote a 30
page summary report of this work.

I was responsible for implementation of an in-line optical pellet sorter to guarantee defect-free product
to critical customers. I originated the idea, researched the available technologies, conducted controlled
tests with a pilot unit to prove the technology and fine tune the specifications for the equipment,
scoped/estimated/obtained funding for the project, supervised installation, and commissioned the unit.
This had previously required 12 people to manually sort a fraction of the product; now we were able
to automatically inspect 100% and guarantee quality for all of it.
Developed grass roots vibration monitoring program and performed routine analysis. Data driven
recommendations on a 700 hp and 1000 hp motor avoided $2MM in lost production.
Supervised rotating equipment check-out/commission in new unit, established spare parts inventory
for 300 pieces of equipment.
Developed grass roots maintenance and inspection policies & procedures for vessels, tanks, piping.
Filled in for Maintenance Manager for 3 months while he was on an overseas assignment. We
remained within budget and equipment on-stream time remained at 99.7%.
Hands on support, including literally assisting craftsmen with tools on emergency overhauls of
diaphragm metering pumps, gear product pumps, and fluid bed dryer fans.
QUANTUM CHEMICAL
May 1991 to April 1994
Project Engineer, Deer Park, Texas
Responsible for scope/estimate development, equipment specification, construction of projects up to $5MM

Managed a $300K cyanide wastewater discharge reduction project. We were under an enforcement
deadline from the EPA and faced $6MM in fines. Worked with a chemist to develop a unique process
design, obtained expedited approval of funds from the divisional vice president, and worked 90
hrs/week to complete this project successfully.

Managed a $1MM air emissions reduction project in a slurry HDPE unit. We were also under an
enforcement design from the EPA. A similar plant had installed a $7MM incinerator to destroy this
waste. Came up with a successful alternative solution for $1MM. The preliminary scope/estimate
inherited was off by over 100%. Detailed scope documents and control estimate, which eventually
became a department standard, resulted in a project that was completed within 0.5% of budget.
