The U.S. Coast Guard (USCG) has issued a Request for Information (RFI) for market research to identify mature technologies for quantitative "in-water" underwater hull scanning of its 154' Fast Response Cutters (FRC). This capability aims to determine hull plating thickness and identify defect areas prior to drydocking, thereby improving repair planning and avoiding unplanned drydock extensions. The RFI requests information on scan resolution, ability to scan through fouling/coating, hull thickness capabilities, equipment description, support for full and targeted hull scans, estimated duration, Technical Readiness Level (TRL), classification society recognition, and personnel requirements. Responses are due by November 21, 2025.
This government file outlines the detailed requirements for inspecting hull plating using automated crawler ultrasonic inspection (SIDESCAN) and handheld methods. The inspection aims to detect metal corrosion and deterioration on underwater hull plating and freeboard up to the main deck edge. Key requirements include performing scans in the presence of a Coast Guard Inspector or COR, specific technician qualifications (ASNT Level III/II certifications), and adherence to SIDESCAN standards like scanning resolution and coverage areas. The document prohibits "Echo-To-Echo Transducers." It also details guidelines for handheld scanning in areas not covered by automated methods, including calibration and resolution settings. Evaluation criteria for scan data categorize wastage into "RED" (≥25% wastage), "YELLOW" (10-24% wastage), and "DARK GREEN" (<10% wastage) repair areas. Reporting requirements are extensive, demanding electronic files with narrative summaries, plate summaries, composite mosaics, individual plate scan images, and photos of repair areas. All data generated becomes the sole property of the US Coast Guard.
The Department of Defense (DoD) "Technology Readiness Assessment Guidebook" (February 2025) outlines the process for conducting high-quality Technology Readiness Assessments (TRAs) for acquisition programs. This guide, which supersedes previous editions and incorporates recommendations from the 2020 GAO Technology Readiness Assessment Guide, emphasizes the importance of TRAs in evaluating the technical maturity of critical technologies (CTEs) using Technology Readiness Levels (TRLs) from 1 to 9. The guidebook details TRL concepts for both hardware and software, provides specific assessment considerations for various systems (e.g., aircraft, missiles, space systems), and highlights the characteristics of a high-quality TRA: credibility, objectivity, reliability, and usefulness. It also defines key roles and responsibilities for TRA participants and outlines a five-step process for planning, assessing, and reporting TRAs, ensuring they inform decision-makers and mitigate risks in acquisition programs.
