Seacor Holdings filed papers to spin off its offshore marine business. 

The spin-off is a first step toward rolling up peer companies during the industry downturn. Private equity fund Carlyle Group may end up with a big chunk of the new company through a 2015 debt deal. 

Seacor Marine Holdings, as the new company will be named, will be a tax-free spin off to Seacor Holdings shareholders, according to the registration statement.
