Energy Consumption Modeling and Sensitivity Analysis for Deep-Argo Otarriinae Profiling Float

الملخص EN

Deep-Argo Otarriinae profiling float is a new type of Argo profiling float that has a maximum diving depth of more than 4,000 m.

It can collect ocean scientific data all-weather and uninterruptedly, which provides reliable data support for the global ocean scientific research.

The working time of Deep-Argo profiling float is an important indicator of its practicality and economy, and it is clear that the energy consumption is a key factor in determining its working time.

In this paper, the single profile energy consumption model with 19 parameters of Deep-Argo Otarriinae is established and the main effect indices and total effect indices of the energy consumption parameters to energy consumption are calculated using Sobol’ sensitivity analysis method, aiming to find the parameters that have the greatest impact on energy consumption.

The results show that the gliding angle, the diving depth, and the gliding speed have a significant impact on energy consumption of Deep-Argo Otarriinae.

The results of simulation have a good match with the actual application and have certain reference significance for the determination of the design parameters and the selection of the navigation parameters.

This paper also provides a new idea of multiparameter energy consumption modeling for underwater equipment using buoyancy regulation.
