This regression model accounted for both the first-order interactions between factors, and the competing design objectives discussed above. The results of the experiment were then used to optimize the system based on linear regression of the DoE results. Using the DoE methodology, an experiment was designed to identify the factors that drive mooring system performance and cost.

This approach satisfied the objectives above by applying computer simulations in a Design of Experiments (DoE) framework. MethodologyĪ simulation-based engineering approach was used to design an optimal single-point mooring for a subsea Acoustic Doppler Current Profiler (ADCP). A successful design approach must balance multiple competing criteria without requiring excessive simulation time, while resulting in a mooring system that meets the design criteria under all expected environmental conditions without overdesigning the system.

Increasing the buoyancy creates greater stress on the mooring line and increases the anchor weight requirement. For example, oversizing the mooring line adds weight to the system, which in turn increases the buoyancy requirement. An overdesigned system increases component costs and requirements for deployment assets. An under-designed system could allow excessive instrument motion or movement of the anchor. Furthermore, environmental conditions and seafloor characteristics must be accounted for properly. These criteria include the deployment depth range, acceptable pitch angles, and cost. Numerous competing criteria must be considered when designing mooring systems for oceanographic instruments. Keywords-Acoustic Doppler Current Profiler ADCP Mooring Design Design of Experiments This methodology limited expensive simulation time while resulting in a satisfactory mooring design. A design methodology based on Design of Experiments (DoE) theory was used to develop a mooring system that satisfied all the competing design objectives while minimizing cost. Design criteria included wire rope safety factor, chain load safety factor, ADCP pitch, ADCP knockover (set down), anchor sliding, and the recoverability of the Acoustic Release. Design variables included buoy shape, buoy volume, gravity anchor mass, chain size, acoustic release buoyancy, and wire rope diameter. Target deployment depth, environmental conditions, and seafloor characteristics were identified for the selected site in the Gulf of Maine. Numerous inputs and criteria were considered.
