Lisa Rodriguez, CFO of Hercules Offshore, has stepped down to take on the role of vice-president of human resources.

Vice-president of finance Stephen Butz will instead step up into the role, while keeping his position as treasurer. Butz will also become senior vice-president of the company.

Rodriquez has worked in human resources for the company since 2008 and took over the position of CFO in an interim role in January in 2007.

Butz has worked for the Houston-based company since February 2005 where he started as director of corporate development as it was going through an IPO.
