What does a tank farm operator do?

As a tank farm operator, you receive and discharge industrial chemicals or jet fuel from tanker truck shipments or a pipeline. Your duties include taking a sample within a specified period to analyze product quality using various tests, such as to measure acidity and composition. You also inspect product based on compliance and standards set by your company, the industry, and government. Additional responsibilities include the transfer of product to storage tanks and ensuring all equipment is up to code to avoid spills and contamination. You are expected to maintain an organized log with all product transactions, quality control actions, and any maintenance performed. Each shift, you inspect the hydrant system, tanks, and pipelines, and report anything unusual or outside your expertise to your supervisor including leaks or temperature and pressure abnormalities.

Job description

An exciting career awaits you

At MPC, we're committed to being a great place to work - one that welcomes new ideas, encourages diverse perspectives, develops our people, and fosters a collaborative team environment.

Responsibilities:

As a Chemical Engineer at a Marathon refinery, you can expect to become familiar with process equipment fundamentals and best practices, build critical thinking skills, and gain an understanding of how all engineering disciplines work together as a cohesive team. You will also gain knowledge of various aspects of a refinery by working with a team of professionals who run a specific portion of the refining process. Most often, Chemical Engineers will have an opportunity to work on more than one area of the refinery, leading to a broad understanding of how the plant operates. Finally, you will have the opportunity to expand your written and verbal presentation skills in a professional work environment.

Most Chemical Engineering co-ops and interns enter into the following positions:

Process / Technical Service Engineersmay work on a variety of projects in the Technical Services Department together with your mentor that put your classroom experience as a Chemical Engineer into practice. The vast majority of our Chemical Engineering interns/co-ops work in this area. The experience will expand your understanding of the refining environment and technical aspects of the refinery. Past projects/duties include: develop and lead test runs to optimize refinery operations; perform process engineering calculations concerning the various process technology (or equipment) in the refinery; monitor and make recommendations in regards to catalyst and adsorbents; complete projects and provide recommendations for improvements to the refinery process and equipment.

Operations Research Engineersmay help develop planning, blending, scheduling, and process models for refinery engineers. The models are used to optimize crude oil purchasing, refinery production, blending and finished product scheduling, and optimization of refinery production. Typical college co-op assignments include: validation of production data and mass balancing, process modeling, and development of graphical interfaces of refinery process units.

Environmental Engineerswork on projects that involve the compliance of the entire refinery, and you will be exposed to the majority of process units in the refinery. You will be applying the engineering principles and calculations to various environmental projects and will also give you a broad knowledge of the various environmental laws that are applicable to refineries and what it takes to maintain compliance with those laws. Past projects/duties include: perform process calculations for the Risk Management Plan, including taking physical surveys of refinery process units; work on various process engineering projects within a Wastewater Treatment Plant; participate in inspections and/or testing that is conducted by federal, state, or local officials.

Products Control / Economics Engineersmay work on a wide array of projects including operations, blending, and refinery economics. You will gain an understanding of how a tank farm is operated and how gasoline and other products are prepared and shipped to customers. In addition, you will gain some exposure to the overall economics of the refinery and how operating decisions are made based upon these economics. Past projects/duties include: analyze refinery process flow data and compare to recommended optimum levels, this will help in identifying equipment failures which cause variances in capacity from the optimum levels; update information on gasoline blends and tank samples in preparation for an annual blender waiver audit; develop applications to better present process data for refinery operating decisions.

Qualifications:

  • Candidates must be majoring in Chemical Engineering
  • Strong academic performance
  • Candidates must be authorized to work in the US on a full-time indefinite basis without the need for employment visa sponsorship now or in the future.
