About Nelosca

Our mission is to create and execute innovative solutions to the world's most complex maritime, environmental, and infrastructure challenges. 

We are a fourth-generation, family-owned, marine construction firm that specializes in environmental remediation, dam construction, commercial dive, harbor management, and submarine cable services. Working closely with public and private owners of water-based infrastructure since 1919, Nelosca operates throughout coastal and inland waterways nationwide, while maintaining a large fleet of marine equipment.

For more than a century, we've worked with clients and engineering firms with high levels of integrity and professionalism. We understand that success is not only measured by our outcome, but also through the process by which our outcome is achieved.
