Engineer Mechanical

Profile

Mechanical Engineer (MBA) with over ten years experience engineering

solutions and improving the performance of Rotating Equipment in the oil

and gas industry, mainly working in Petr leos de Venezuela, S.A. (PDVSA).

As Rotating Equipment Engineering Superintendent - CRP, I am managing a

team of 34 Rotating Equipment Specialists, having the ultimate

responsibility for the selection, operation, maintenance, optimization,

trouble shooting, and failure analysis at the largest oil refinery in the

Western Hemisphere (Paraguana Refining Complex - CRP). The CRP complex

includes more than 4,000 pumps, 3,600 electric motors, 70 steam and gas

turbines, and 70 centrifugal and reciprocating compressors.

Equipped with a solid academic background and proven capability, I

successfully managed projects that included design specification, bid

package and purchase order preparation, vendor selection, fabrication,

performance testing, commissioning, start-up, operation, and maintenance of

large, complex rotating equipment. Among other duties, I acted as a

Special Adviser in rotating equipment factory acceptance tests (according

to ASME PTC-1, 6 and 10). Additionally, I have been directly involved in

the repair, upgrade, and replacement of high energy turbo-machinery.

Expertise

. Strong theoretical and applied engineering background in

thermodynamics and rotating machinery

. Demonstrated ability to analyze, diagnose, and improve gas

compression system overall performance.

. Highly capable at problem diagnostics, trouble-shooting, Root Cause

Failure Analysis, engineering solutions, and field service support.

. Significant knowledge in control systems, anti-surge systems,

lubrication and sealing systems, and all compressing and pumping

related systems.

. Knowledgeable of design standards and codes for rotating equipment

and plant design (API, ANSI, ASME).

. Extensive experience in field and project engineering, management,

leadership, mentoring, testing, and problem-solving.

Major Achievements

Increase of the MTBF for centrifugal pumps up to 80 months with 13 $MM

savings in two year, by the design and implementation of a failure

prevention strategy. An ambitious project implemented at the Paraguana

Refining Complex (900.000 BPD refinery), with the primary focus on the

risk and reliability management by the reduction of the failure

probability trough the definition of control and monitoring strategies at

three inspection levels, Level 1 - Asset Inspection, Level 2 - Process

Inspection, and Level 3 - Human Behavior Inspection.

Design and implementation of an In-line cleaning procedure for a 33000 HP

multistage steam turbine, achieving a 60 % reduction on the estimate

downtime for an offline conventional cleaning procedure. The economical

benefits was 15 $MM. This project was presented as a case study at the

Texas A&M University 42th Turbomachinery Symposium in October 2013 and was

highlighted in the November 2014 issue of Turbomachinery International.

Upgrade of the mechanical seals systems for the Alkylation, CCU and LNG

Complex at the Amuay Refinery. The upgrade was designed according to API

682 and the safety requirements of PDVSA. The sealing technology selection

was based on the service temperature, toxicity level, vapor pressure,

specific gravity and mechanical arrangement of each pump. After 2 years of

implementation, the mechanical seals failures were reduce by 40%.

Revamp of the hydrogen compression system of the Amuay Refinery. This

project included the mechanical upgrade according to API 618 of four large

reciprocating compressors and the specification, selection, factory test,

installations, commissioning and start up, of three full-condensation

10.000 HP steam turbines. The cost of this project was +20 $MM.

Modification of blades geometry on a 33.000 HP axial compressor rotor after

a casing thermal deformation. The design process included the rotor and

casing laser scanning, establishment of the new geometry based on the

required clearances and stress and efficiencies calculations. The

implementation of the new design resulted in a 45% reduction of the

estimated down time, equivalent to $7 MM savings, with a 3% compressor

efficiency decrease.
