Seacor Marine Holdings Inc.
A provider of offshore marine support, ferrying cargo and crews to oil, gas, and wind platforms aboard a global fleet of supply ships, fast support vessels, and liftboats. It grew out of SEACOR Holdings, founded in 1989 when attorney Charles Fabrikant bought NICOR Marine and named the firm "SEACOR" so workers could simply paint over two letters of the old "NICOR" signage and save on rebranding. The offshore arm was spun off as its own company in 2017.
