Seacor Marine Holdings Inc., Houston, announced today that Robert Clemons has stepped down as executive vice president and chief operating officer, effective immediately.

Clemons joined Seacor as executive vice president and COO in June 2017, and was previously the vice president and COO of Seacor Holdings’ Americas offshore division.

"Optimizing our executive team is part of an ongoing process to shape our organization and overhead costs to fit the evolving profile of our fleet, our operating activities, and the opportunities available to us.”

Clemons will provide consulting services to the company for a period of time following his departure in order to assist with the transition of his duties. Seacor did not name a replacement for Clemons as COO and has no current plans to fill the position.
