• Estimated process fixed equipment (piping, pressure vessels, storage tanks) useful life used in refineries for depreciation accounting purposes • Proposed a mathematical model to estimate the useful lives per type of equipment, based on historical registries of the service life of equal or similar equipment installed in oil refineries • Formulated the model proposed in Microsoft Excel and populated the spreadsheet with the equipment database provided by the oil refinery personnel • Wrote the process static equipment section in the final report to the client explaining the mathematical model proposed, the technical and accounting considerations assumed, and the obtained results

• Delivered an RBI analysis under API 581 covering 703 assets (including pressure equipment and piping) in 3 facilities and developed an inspection plan to reduce the future risk of 25% of the assets to acceptable levels • Designed and implemented an algorithm in Excel to integrate the improvements on the Probability of Failure PoF calculations of API 581 (2016) into the client's risk-based inspection RBI procedure and present risk results in the client's Risk Prioritization Matrix • Identified a cost reduction opportunity in biocide injection for one of the two off-shore platforms by comparing their bacteria colony count´s trends during the potential damage mechanisms identification stage

• Led and delivered satisfactorily a baseline inspection (VT, UT thickness measurements, isometrics) covering 763 assets (706 process pipings, 23 tanks, and 34 pressure vessels) in 3 facilities, under API 510/653/570 • The execution of the baseline inspection and its final report was considered a successful case and adopted as the guideline for similar analyses for the client's facilities in Peru. Also, the Client's operations department adopted the RBI's process flow diagrams (PFDs) updated during this activity • Delivered an RBI analysis with software ORBIT (DNV) covering 740 assets (including pressure equipment and piping) in 2 facilities and developed an inspection plan that reduced inspection costs by 15% in 5 years • Performed certified API 510 internal and external inspection of 8 pressure vessels (flare KO drums, cementing silos, gas separators, and condensates drums)

• Used an RBI analysis with software ORBIT (DNV) for PSVs to issue an inspection and testing plan aligned to API 576 for 100 PSVs in 2 facilities, achieving a testing cost reduction of 46% in 6 years • Led the information and data gathering, facilitated RBI workshop, and issued an inspection and mitigation plan for 178 assets (18 tanks, 13 separators, 24 drums, 114 process pipings, 9 fin-fan coolers) in 2 facilities using the client's proprietary methodology aligned to API 580 • Led the information and data gathering, facilitated risk assessment workshop, and issued an inspection and mitigation plan for 28.6 km of oil pipelines and 204 km of flow lines (210 lines) using the client's proprietary methodology aligned to API 1160 and ASME B31S • Inspected, did mechanical integrity assessment, and issued an inspection report for 60 assets (27 pressure vessels, 4 tanks, 15 process pipings, 12 fin-fan coolers, 1 boiler) under API 510/653/570/661 • Performed certified API 510 internal and external inspection of 2 pressure vessels (3-phase separator, thermal electrostatic treater) • Performed the conceptual design of the mechanical integrity database and supervised the upload of 55,000 data belonging to 2,250 assets • Proposed and implemented a semi-quantitative methodology to estimate the probability of failure of 5,800 bolted flange joints (in 2 facilities) based on aspects such as process, environment, QA/QC compliance, joint assembly, and management • Diagnosed the corrective actions needed to ensure the client's inspection, testing, and reporting practices compliance to the corporate pressure vessel certification program, including HSE and mechanical calculations training • Developed and executed a corporate pneumatic test procedure successfully and safely according to the standard ASME PCC-2 • Determined for the first time the cost of a fatality for the client as part of the RBI analysis for 27 treaters (thermal, electrostatic, thermal-electrostatic) in 3 facilities

• Participated in projects valued at £16 million approximately that improved 350 streets within the borough • Supported the Capital Projects and Maintenance teams with producing high-quality and accurate drawings of designs involved in the planned maintenance and new developments on the Highways within the London Borough of Ealing. The drawings were part of the deliverables required for the feasibility and implementation stages of projects executed in footways and carriageways

• Increased the number of regular accounts, from 8 to 35, which represented the most important contribution to the sales quotas, due to a proactive customer service approach. • Made a reputation for the company in the product development and manufacture of sheet metal pieces for slot machines • Managed and developed new subcontractors to increase the range of services on offer, mainly to target the mining sector where thicker pieces were required, this action raised the sales locally and nationwide • Gave commercial and technical advice directly to customers on manufacturing processes (shearing, folding, and punching) for the production of sheet metal pieces made of plain carbon, stainless steel, and aluminum, ranging between 0.5-6.35mm in thickness and where high precision was the main requirement.
