About

Founded in 1964 by J. Arnold Witte, Donjon Marine’s principal business activities were marine salvage, marine transportation, and related services.

Today, Donjon Marine Co., LLC offers the marine community full-service solutions to meet every need in marine salvage, dredging, material recycling, and related services.

Donjon’s controlled expansion into related businesses such as dredging, ferrous and non-ferrous recycling, and heavy lift services is a natural progression, paralleling our record of solid technical and cost-effective performance.

Since our founding, Donjon Marine has continued to diversify in response to the ever-changing marine market while building on its original focus on marine services.
