During my internship at the Naval Surface Warfare Center Carderock Division (NSWCCD), I contributed to the development of next-generation autonomous systems for Unmanned Surface Vessels (USVs). This experience provided invaluable insight into the intersection of naval engineering, autonomous systems, and modern software development practices.

Project Overview

The project focused on developing autonomous capabilities for naval surface vessels, requiring:

  • Robust autonomous decision-making in dynamic maritime environments
  • Real-time system performance for safety-critical operations
  • Integration with existing naval systems and protocols
  • Extensive testing and validation for mission readiness

Agile Development in Naval Context

Methodology Implementation

Working with Agile methodologies in a defense context presented unique challenges:

  • Iterative development cycles to rapidly incorporate feedback
  • Stakeholder collaboration with naval operators and engineers
  • Incremental capability delivery to demonstrate progress
  • Sprint-based feature development with clear deliverables

Stakeholder Communication

I authored clear and concise BLUFs (Bottom Line Up Front) for stakeholders to:

  • Ensure alignment on project objectives and progress
  • Facilitate informed decision-making at all organizational levels
  • Communicate technical concepts to non-technical stakeholders
  • Maintain transparency in development progress

Technical Implementation

Large-Scale Simulation

Conducted extensive testing using large-scale simulation environments:

  • Dynamic environment modeling to simulate real-world conditions
  • System verification under various operational scenarios
  • Performance benchmarking against naval requirements
  • Risk assessment for autonomous decision-making algorithms

NEMA 2000 CAN Integration

Worked extensively with NEMA 2000 CAN bus systems for:

  • Marine electronics integration following industry standards
  • Real-time data exchange between vessel systems
  • Sensor data aggregation from multiple maritime sensors
  • Command and control communication with autonomous systems

Parker PLC Systems

Integrated with Parker Programmable Logic Controllers to:

  • Control vehicle actuators for steering and propulsion
  • Monitor system parameters for operational status
  • Implement safety interlocks for autonomous operations
  • Provide operator interfaces for manual override capabilities

System Architecture

Communication Systems

Implemented robust communication capabilities:

  • Status reporting to remote operators
  • Command reception for mission updates
  • Data logging for post-mission analysis
  • Emergency communication for critical situations

Challenges and Solutions

Maritime Environment Complexity

Naval autonomous systems must handle:

  • Variable weather conditions affecting sensor performance
  • Complex traffic patterns with multiple vessel types
  • Regulatory compliance with international maritime law
  • Security considerations for naval applications

Real-Time Performance Requirements

Critical system requirements included:

  • Low-latency response to environmental changes
  • Deterministic behavior for safety-critical decisions
  • Fault tolerance for mission-critical operations
  • Graceful degradation when systems fail

Skills Developed

This internship significantly enhanced my expertise in:

  • Maritime systems engineering and naval applications
  • Industrial communication protocols (NEMA 2000, CAN)
  • PLC programming and integration with autonomous systems
  • Agile project management in defense contexts
  • System simulation and testing methodologies
  • Working within multidisciplinary teams of engineers, operators, and contractors

Impact and Applications

The work on autonomous surface vessels has broad applications:

  • Naval operations for reconnaissance and patrol missions
  • Maritime security for port and harbor monitoring
  • Commercial shipping for automated cargo operations
  • Scientific research for oceanographic data collection

Future Implications

Autonomous surface vessels represent a significant advancement in:

  • Naval capability enhancement with reduced crew requirements
  • Maritime safety improvement through automated collision avoidance
  • Operational cost reduction for routine maritime tasks
  • Risk mitigation for dangerous maritime missions

This experience at NSWCCD provided deep insight into the complexities of developing autonomous systems for real-world naval applications, combining cutting-edge technology with the rigorous reliability requirements of naval operations.
