Matthew Cenac has stepped down as the chief financial officer of Seacor Marine Holdings, the Louisiana-based spin-off of Seacor Holdings announced today.

The company said Cenac, whose departure was effective yesterday, "played a key role" in its transition after spinning off from Seacor Holdings.

Seacor Marine Holdings declined to say why Cenac left his post but said he will provide consulting services for six months to help the company with the transition of his duties.
