Seacor Marine has acquired three new vessels in a ships-for-shares deal.

The Louisiana-based offshore company will receive three fast support vessels (FSV) from the McCall family — whose patriarch, Normal McCall, merged his company with Seacor in the 1990's.

Seacore is using 603,872 shares to fund the transaction. At the open, Friday, Seacor Marine shares were trading at $12.87.

"We are excited to expand our FSV fleet, a core asset segment for SEACOR Marine," said chief executive John Gellert.
