Services would be performed at PSNS&IMF, a naval shipyard location. Interested sources must demonstrate relevant capabilities, including experience with similar vessels, required certifications (e.g., NAVSEA MSRA/ABR, SSPC QP1), and security clearance access for management and non-management personnel. No budget amount is specified in the announcement.
