General Repair and Maintenance Services Electrical, Welding & Sheet Metal


Because we perform such a wide range of repair and maintenance services — either with our own labor or with a close network of subcontractors — we take the hassle out of marine repair and maintenance. It’s easy to work with us.


For work on U.S. Navy and other military ships, we maintain company and personnel security clearances required for work in secure spaces on surface ships and submarines. We are a secret-cleared facility with cleared personnel. The highly technical nature of our work demands specific expertise, so we hold numerous technical certifications including 30 approved welding procedures.


HVAC Maintenance & Repair Services


Regular HVAC maintenance is essential to maintaining a comfortable and safe onboard environment. Proactive, planned maintenance programs also reduce operating costs and minimize the risk of downtime.

Trident’s planned maintenance services include preventive, reliability-centered (RCM), and condition-based (CBM) maintenance as well as vibration analysis. Trident also helps customers develop a tailored HVAC maintenance strategy that includes lifecycle cost management and spare parts management.
