The contribution of this thesis is threefold. First, it provides a thorough example of an engineering designer's approach to solving a complex open-ended design problem. Second, it presents a compendium of requirements and respective key strategic drivers to fulfill those requirements when designing a machine for a marine environment. Third, it presents a two-axis gimbal system design for marine applications. The scope of the design includes requirements through a preliminary design review with focus on methods to generating solutions, analyzing and evaluating those solutions, and selecting the best option. Analysis aspects cover design methods for resistance to the effects of greenwater loading, wind loading, vibration loading, shock loading, icing/freezing rain, temperature, humidity, corrosion, and foreign object ingress in a marine environment. The deterministic design methodology and design tools are applied from Slocum's Fundamentals of Design in which the design generation and selection steps are iterated from a strategic level down to individual components. The resulting two-axis gimbal system design is a compact, environmentally rugged, side-table, split-payload style gimbal that fulfills the desired requirements. This gimbal system differs from most commercially available systems with enhanced design features for severe operational loading environments, severe environment resistance, and increased system accuracy, repeatability, and maintainability.
