Variable buoyancy technology is advancing autonomous underwater vehicle performance by reducing reliance on energy intensive thrusters. Integrating a pump driven buoyancy system with advanced control algorithms, researchers demonstrated efficient depth keeping, improved manoeuvrability and extended endurance. The approach offers a promising pathway for longer, more capable underwater missions today ahead.

Autonomous shipping trials are driving regulatory evolution across international maritime governance frameworks. Examining MASS, flag-state responsibilities, safety conventions, alternative design provisions, and unmanned bridge operations, the analysis highlights key legal, operational, and certification challenges. The findings support safer, scalable, autonomous vessel deployment while maintaining compliance with established maritime regulations worldwide.

Autonomous underwater transportation using multiple AUVs faces significant challenges from sea-current effects. Through nonlinear dynamic modelling and time-domain simulations researchers evaluated payload limits and control-system performance under opposing and cross-current conditions. Results showed effective PID-controlled operation against head currents while transverse currents induced instability and undesirable pitch oscillations at sea.

Coordinated underwater transport using multiple autonomous vehicles demands precise dynamic modelling and control optimisation. Researchers developed a nonlinear coupled system and demonstrated successful payload guidance through PID controlled trajectory tracking. Increasing controller gains improved responsiveness reduced lag and enabled reliable mission execution highlighting practical advances in cooperative AUV transportation systems
