Introduction to Underwater Vehicles

Underwater vehicles are remarkable tools that allow scientists and researchers to explore the mysterious depths of the ocean. They play a crucial role in expanding our understanding of marine environments and assisting in numerous underwater tasks, from scientific research to commercial operations.

What Are Underwater Vehicles?

Underwater vehicles are specially designed machines used for underwater exploration and tasks. They are categorized primarily into two types: manned and unmanned.

Manned Submersibles: These vehicles are equipped to carry people and are used for short-duration expeditions. They often have a spherical cabin to withstand high pressure.
Unmanned Vehicles: These include both remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), which are piloted remotely or operated independently.

Remotely Operated Vehicles (ROVs): Vehicles controlled by operators via a tether (cable) that carries an electrical signal to the vehicle, used for a variety of underwater tasks.

Autonomous Underwater Vehicles (AUVs): These vehicles operate independently of direct human control using pre-set programming or decision-making software.

Imagine an AUV conducting a seabed survey to map the terrain. It navigates autonomously, gathering data using onboard sensors, which is later analyzed by scientists to understand marine geology.

Did you know? The deepest dive by a manned submersible, the Trieste, reached the bottom of the Challenger Deep in the Mariana Trench in 1960.

Significance of Underwater Vehicles

Underwater vehicles have expanded human capacity to inspect, survey, and interact with underwater environments, crucial for the following reasons:
