Hanson Maritime Co.

Contracting Service

Hanson Maritime Company, a marine contractor specializing in salvage, towing and  commercial diving.  Also offering pollution response, and light marine construction.


Hanson Maritime Company started in 1993 as Underwater Services, specializing in commercial diving and salvage.  In 2000 we started towing and changed our name.  We have successfully salvaged over 100 vessels, and changed well over 100 propellers underwater.  We practice an almost forgotten method of salvage where we respond immediately to vessels in peril, often resulting in rescue rather than salvage, and always using our best endeavors to minimize further damage, and to preserve vessel and cargo value.
