“ZEBNO LLC is awesome. They fulfilled
my project on time and under budget”
Client:
US Navy
Situation:
The U.S. Navy required critical design improvements and system upgrades for their shipboard electrical systems, which were based on microgrid architecture similar to facility distribution systems. The project needed to address multiple reliability issues, including the lack of redundancy in generator control, potential shorting in indicator systems, and incomplete shock qualification for components intended for future ship classes. Additionally, ship personnel required enhanced troubleshooting guidance to maintain and operate these systems effectively.
Action Plan:
Designed a backup, remote speed control system for the generator control at switchboards to improve operational flexibility and redundancy.
Redesigned the switchboard indicators, replacing LED lamps with incandescent lamps to mitigate the risk of shorting in the indication system.
Analyzed and extended shock qualification test results to include additional components for use on future U.S. Navy ships.
Reverse-engineered the Generator Voltage Regulator System (VRS) software to develop detailed technical manuals, improving ship crews’ troubleshooting and operational capabilities.
Conducted risk analyses and cost-benefit assessments to support each design improvement and provided thorough communication across all engineering, management, and stakeholder teams.
Results:
Enhanced system reliability and operational flexibility by adding a critical backup to the generator control system.
Improved safety and system durability by preventing shorting in the indication systems.
Reduced future testing costs and timelines by extending shock qualifications to additional components.
Delivered user-friendly technical manuals that significantly improved maintenance efficiency and troubleshooting for ship crews.
Ensured cross-functional alignment and informed decision-making through comprehensive risk and cost analyses.

time and money.”
Client:
US Navy
Situation:
The U.S. Navy was experiencing significant maintenance issues, including overdue electrical system preventive maintenance tasks, an expired machinery indication system that compromised operational accuracy, and an outdated maintenance management system that no longer supported efficient tracking or execution of maintenance activities.
Action Plan:
Completed all overdue electrical system preventive maintenance tasks to bring systems back to compliance and restore operational schedules.
Calibrated the expired machinery indication system to ensure accurate monitoring and system performance.
Executed a force revision to update, standardize, and streamline all maintenance procedures, improving future maintenance efficiency.
Results:
Restored system reliability and improved operational readiness, reducing the risk of unexpected failures.
Saved time and reduced maintenance costs through optimized processes and up-to-date maintenance protocols.
Secured favorable inspection and survey outcomes, demonstrating the effectiveness of the corrective actions and meeting Navy operational standards.
“We could not have had the success
we had without ZEBNO LLC”
Client:
US Navy
Situation:
Following the major overhaul of a Los Angeles-class nuclear-powered submarine, it was critical to perform comprehensive
testing of the nuclear instrumentation and control (I&C) systems to ensure operational safety, regulatory compliance, and
mission readiness. The complexity of the submarine’s systems and the precision required for nuclear operations
necessitated a meticulous and coordinated testing approach.
Action Plan:
Developed and executed a detailed testing plan aligned with naval nuclear safety protocols and OEM specifications.
Coordinated with shipyard engineers, shipyard technicians and shipforce to conduct functional and performance validation of I&C components, including reactor protection systems, monitoring sensors, and control interfaces.
Implemented rigorous step-by-step testing procedures to verify system integrity, signal accuracy, and fail-safe responses.
Documented all test results and worked collaboratively to resolve any discrepancies or performance deviations identified during the process.
Results:
Successfully validated the full operational capability of the nuclear I&C systems, ensuring compliance with all nuclear
safety standards and naval readiness requirements.
The submarine was cleared for sea trials without delay, contributing to the timely return to fleet service and mission deployment.
