The results show that under the same jet conditions, adding a DRA significantly reduces nodule collection time, and a DRA concentration of 1000 mg/L is a suitable choice based on overall considerations. Under the coupled effect of jet velocity and travel velocity, DRA enhances jet energy to improve nodule detachment efficiency and effectively reduces nodule aggregation caused by vortices, facilitating collection.

The framework integrates stay region identification, behavior-oriented segmentation, and multi-feature adaptive compression, enabling differentiated compression across various navigation phases. Stay regions are identified using motion features and spatial density. Navigational behavior patterns are constructed from course sequences, and segmentation is performed using a combination of discrete wavelet transform and entropy-based techniques. Furthermore, introduce multi-dimensional deviation factors and trajectory bending factors, while dynamically setting the compression threshold through a baseline scale adjustment mechanism. In experiments across three representative maritime regions, our method achieves an average compression rate of 78.4 % with a mean spatial error of only 57.8 m, while also maintaining low speed error (0.154 kn) and course error (26.9°).

Different from conventional swipe method, a truss element is used to simulate the rope, with one end connecting to the foundation and the other end for loading, resulting in the same direction of displacement and load. Validation across various types of foundations, including circular surface footings, suction caissons, tripod buckets, and composite pile-bucket foundations, covering a range of shallow to deep foundation categories, under diverse cohesive soil conditions, highlights its robustness.

Based on this framework, the preference interval multiobjective particle swarm optimization algorithm (P-IMO-PSO) is proposed. The proposed algorithm integrates the decisionmaker’s preference information to guide the optimization process. This approach balances navigation time, path safety, and energy consumption while improving iteration efficiency. The results of MATLAB simulation experiments validate the performance of the proposed algorithm under different ocean current models and uncertain environmental conditions. The results show that, compared with the traditional IMO-PSO algorithm, the proposed P-IMO-PSO significantly enhances path-planning efficiency by reducing the mean navigation time interval by 20.85 %, while also optimizing navigation time, mitigating randomness, and accelerating convergence In addition, the paths generated by the proposed algorithm align better with decision-maker (DM) preferences, leveraging ocean currents advantageously while ensuring safety, thereby enhancing AUV navigation efficiency.
