Marine Services Division (MSD)

Our Marine Services Division has more than 30 years of experience in providing full-service ship repair capabilities for U.S. Naval vessels including submarines, surface ships and craft, and deep submergence systems.

Operating from state-of-the-art facilities in Chesapeake, Virginia, we are certified in Submarine Safety (SUBSAFE) and Deep Submergence System Scope of Certification (DSS-SOC) repair activities, and specialize in the design, repair, maintenance, modification, and installation of hull, mechanical, and electrical (HM&E) systems.

We perform high-consequence maintenance on assets that operate in demanding environments. Global locations and certifications enable us to meet even the most time-sensitive and critical schedule deadlines.
