Marvin J. Migura will step down as executive vice president of Oceaneering International Inc., effective Dec. 31, the company said Oct. 5.

Migura will remain a senior vice president, reporting to CEO M. Kevin McEvoy, and remain a part of the executive management team at least through the end of 2016, the company added.

Alan R. Curtis, senior vice president and CFO, and Eric A. Silva, senior vice president-operations support, will report directly to McEvoy, the company said.

Migura joined Oceaneering in 1995 as senior vice president and CFO and was appointed as executive vice president in 2011.

"Marvin has been an integral member of the executive leadership team at Oceaneering since he joined the company. I truly enjoy working with him and look forward to his continued involvement in the company's strategic decision making process and in investor relations. Furthermore, Marvin's gradual move toward retirement will help assure a smooth transition to our recently announced senior-level management changes," said McEvoy.

Oceaneering International Inc. is based in Houston.
