This page is a showcase of professional work & personal projects, and a place to keep a record of those things. This is a living document and will be updated regularly.
During the fall of 2020 I occupied the position of Associate Electrical Engineer in the Systems Integration for Intelligent Transportation Systems (SIITS) Department supporting the San Francisco Municipal Transportation Agency (better known in San Francisco as MUNI). Primarily this role focused on Train Control Engineering in support of the Automatic Train Control System that supports operation of light rail vehicles through the Market St. and Central Subway tunnels. Additionally, the team soon absorbed the Radio & Computer Aided Dispatch systems for both rail and rubber tire (bus) and focused on supporting those systems as part of the Technical Program umbrella. The list below highlights some of the major projects I lead during my tenure:
Starting in July 2014 I assumed the role of Instrument & Electrical Engineer at Chevron Richmond Refinery. I worked throughout the refinery in a variety of functions including supporting daily plant operation, plant outage/shutdown activities, emergency break-in work, and capital and expense projects. This role primarily focused on the instrumentation and electrical infrastructure in the refinery and the work assignments varied in complexity from simple instrument replacement to complete equipment control and/or electrical distribution overhaul. All projects led by me included managing project budget and timeline. The list below highlights some of the major projects I championed:
For 18 months between 2019 & 2020 I supported the event scoping, planning, & construction package writing for the 2020 FCC Major Shutdown. I was the lead Instrument & Electrical engineer for this event. For this event I personally completed/designed 7 construction packages of various complexity to be executed during the event window. In addition I was the lead engineer, project manager, and construction representative on a 10 MVA temporary power system to supply construction power for various in plant loads during the event. This temporary power system utilized a permanent 12.47kV plant power source instead of on-site diesel generation. This voltage was routed throughout the plant and stepped down to 480V and 120V.
Design work and in-field installation of (2) 600HP common DC bus Variable Frequency Drives in existing cabinets. Project tasks and design work included: Component mounting design, cable selection and routing, protection sizing, drive selection, DC bridge component selection, and final drive programming and startup.
For 18 months between 2018 & 2019 I supported the event scoping, planning, construction package writing, and in field execution support for the 2019 TKC Major Shutdown. I was the lead Instrument & Electrical Engineer for this event. For this event I personally completed 8 design construction packages of various complexity to be executed during the event window.
For 6 months in 2018 I supported the event planning and in-field execution support for the 2018 TKN Major Shutdown. For this event I supported in field installation of roughly 34 design construction packages of various complexity and assisted with plant startup.
Design work and in-field installation of new panel mounted speed control, & overspeed protection controllers in seperate existing cabinets for 3 large steam turbines. Project tasks & design work included: modifying existing cabinet to mount new controllers, interfacing new controllers with existing PLC (and modifying PLC program, Field HMI graphics, and increasing modbus mapping size), ensuring redundant physical trip strings integrity after change, and final controller programming and startup.
Design work and in-field installation of new 13 section outdoor NEMA 3R Motor Control Center. Project tasks & design work included: Writing the specification package sent out for bid which included project required specifications for MCC layout, component selection (breakers, overloads, contactors, & relaying), bus sizing, bus material specification, connection styles, protective relaying (including all protection settings). Responsible for arc flash calculation re-validation, motor starting study, final issued for construction package review, and startup support.
For 12 months between 2017 & 2018 I supported the event scoping, planning, & construction package writing for the 2018 2SRU Major Shutdown. For this event I personally completed 6 design construction packages to be executed during the event window.
For 18 months between 2015 & 2016 I supported the event scoping, planning, construction package writing, and in field execution support for the 2016 Richmond Lube Oils Plant Shutdown. For this event I personally completed 42 design construction packages of various complexity to be executed during the event window.
Design work and in-field installation of new 460V 3-phase 200HP IEEE 841 induction motor. Project tasks & design work included: motor specified to meet IEEE 841 and local standards, motor starter selection, motor control scheme design (including interfacing with DCS & new logic creation), conduit/cable tray sizing & routing, & cabling specification.
Design work and in-field installation of two new API 53A pump seal plans on two existing pumps. Project tasks & design work included: specifying barrier fluid reservoirs, design height of reservoirs relative to pump seal chambers, tubing routing to pump seal chamber ports, specification of nitrogen booster skid & required instrumentation.
The list below highlights some of the equipment I have experience sizing, specifying, ordering and installing:
During the summer of 2012 I occupied the position of Summer Intern in Electrical Distribution Planning supporting the San Jose region. The list below highlights some of the major projects and responsibilities I was involved in and completed during my summer internship:
