Ships & Submarines

CTRL began working with the US Navy in the early 2000’s. NAVSEA 04RM and the Maintenance Engineering Technology Team (METT) funded shipboard testing aboard the USS Gunston Hall in order to identify an inexpensive technology to significantly improve maintenance practices, reduction in man-hours, and improvement in fleet readiness.

CTRL in the US Navy

The test evaluated the UL101 in the areas of watertight door integrity, fluid systems leakage, valve leak-by identification, compartment integrity inspections, gear train and bearing inspections, faulty electrical component identification, and rotating machinery integrity. The UL101 performed well in all areas as determined by test engineers and sailors. The report recommended fleet-wide deployment within a 2 year period. In addition, the UL101 has been evaluated and authorized by specific departments such as the Vacuum Wastewater System that were not included in the original review. Most recently, the UL101 was evaluated by the Navy and Penn State University Applied Research Lab (PSU ARL) to determine its capability to detect electrical problems and mechanical looseness in panels with closed doors whereas current infrared technologies require direct line of sight. The successful findings were reported to the Tech Warrant Holder and recommendations were made for fleet wide use of the UL101 for electric panel and switchgear inspection.

Military Naval Surface & Subsurface Applications

CTRL has worked closely with the U.S. military for the testing and approval of its ultrasound technology to several applications onboard both surface and subsurface ships. The following chart demonstrate just a few of the applications for which CTRL ultrasound technology has been tested and approved.

CTRL UL101 Selected by Canadian & Australian Navies

Other navies have tested and adopted the use of CTRL technology due to its demonstration of success in the United States navy. Information has been shared with allies on the technology benefits for fleet readiness and costs savings. The UL101 is procured through the Foreign Military Sales (FMS) program. Other allied militaries benefit from this program as well, indicating a greater adoption than those for which CTRL has worked directly.
