Ohio Northern University’s T.J. Smull College of Engineering honored Craig O. Pierson, president of Marathon Pipe Line LLC, and Timothy Quellhorst, senior vice president of Crown Equipment Corporation, with Distinguished Alumni Awards on Feb. 22.

Pierson, who graduated with a Bachelor of Science in mechanical engineering in 1978, joined Marathon Pipe Line Company in June 1978 as a pipeline engineer in Martinsville, Ill. He next moved to Findlay, Ohio, as an internal control auditor for Marathon Oil Company and then back to a number of pipeline engineering and pipeline operations positions in Wyoming, Alaska, West Texas and Houston. In 1989, he rejoined Marathon Oil Company to help develop a gas pipeline project in Syria. In 1991, Pierson was named manager of engineering and construction services with responsibilities in the retail-marketing sector.

He then held operations manager positions for Marathon Pipe Line in Casper, Wyo., and Martinsville, Ill., until 1997, when he joined Marathon Oil Company on its upstream development project on Sakhalin Island, Russia. In 1999, Pierson was named facilities design manager for the Phase 2 development of the Sakhalin Project, which included the offshore and onshore production facilities and pipeline, and the oil export terminal. In 2000, Pierson returned to operations manager positions for Marathon Ashland Pipe Line LLC, with responsibilities over Gulf Coast operations. In January 2005, he was named vice president of operations for Marathon Pipe Line LLC.

In May 2011, Pierson assumed his current position as president of Marathon Pipe Line LLC. He also is vice president of operations for MPLX GP LLC. Pierson serves on the board of the Louisiana Offshore Oil Port, and he is an owner representative for Marathon’s interest in Capline; both entities are significant parts of the nation’s crude oil infrastructure.

In 2007, Pierson was appointed as industry representative on the Technical Hazardous Liquid Pipeline Safety Standards Committee, which advises the Pipeline and Hazardous Materials Safety Administration on regulatory matters. He also serves on the Pipeline Safety Excellence Steering Committee, which helps to improve the industry’s safety performance. Pierson is the current chair of the American Petroleum Institute’s Pipeline Subcommittee.

In this role, he oversees research and development, current product support, and technology business development activities for all Crown products, both in the United States and overseas. The engineering and design offices in New Bremen, Ohio, and Munich, Germany, report to him, and he oversees the mechatronics research being conducted at Crown’s research center in Auckland, New Zealand. His responsibilities require extensive international travel, and he has visited customers, suppliers and other business-related operations in 13 different countries.

Quellhorst first joined Crown in 1988 as a mechanical engineer and since then has held a number of positions, including vice president of engineering, director of engineering, and engineering manager. During his 27-year career with Crown, he’s either been a contributing member of the new-product design team or overseen the engineering effort for every product that Crown manufactures today.
