Profilers AUVs: Equipped with sensors that allow them to collect comprehensive oceanographic data, profilers usually follow a pre-programmed path and operate autonomously. This makes them ideal for gathering data over large areas and depths and valuable for studying ocean conditions and climate change.
Mapper AUVs: Utilise advanced sonar systems to capture topographical data, including underwater features and bathymetric information, which are essential for charting underwater terrain, geological surveys, and resource exploration. The detailed maps mapper AUVs produce help understand seafloor structures and plan sub-sea operations.
Survey AUVs: Employed to conduct environmental surveys and collect samples from underwater environments with sensors and tools designed for scientific research, including measuring water quality and collecting biological samples. Survey AUVs are crucial in marine research, helping scientists monitor ecosystems, assess marine environment health, and study environmental changes' impacts.
Long-endurance AUVs: These are built for extended missions, often in deep-sea environments, and can operate for weeks or even months, gathering data over long periods. They are used for deep-sea exploration, long-term environmental monitoring, and data collection from remote locations. Their extended operational capability allows continuous data collection in challenging and inaccessible areas.
Search and Recovery AUVs: These vessels, designed to locate and recover objects from the ocean floor, are equipped with sensors and tools that help identify and retrieve lost or sunken items. They are used in various operations, including searching for shipwrecks, locating lost equipment, and conducting salvage operations.
Remotely Operated Vehicles (ROVs)
Observation ROVs: Equipped with high-resolution cameras and other imaging tools to provide real-time video and photographic data of underwater environments. They are primarily used for visual inspections and exploratory missions, offering detailed views of underwater conditions and structures.
Work ROVs: Designed for complex underwater maintenance, repair, and construction tasks, they are equipped with heavy-duty manipulators and specialised tools to perform intricate operations on sub-sea infrastructure. Their robust design allows them to handle demanding tasks in challenging environments.
Lightweight ROVs: These are designed for more straightforward, less demanding tasks to deploy in shallow waters and for basic inspection and exploration activities. Often employed by hobbyists, these ROVs offer a cost-effective solution for lighter operations. Their compact design makes them suitable for recreation and less critical underwater work.
Specialised ROVs: Tailored for specific applications like scientific research, underwater archaeology, or military operations. They are equipped with advanced tools and technologies to address unique mission needs. These ROVs offer enhanced capabilities and features for specialised tasks. Their design is optimised for complex or niche applications, making them essential for targeted operations.
Inspection ROVs: Equipped with high-resolution cameras and essential inspection tools to evaluate underwater structures. They are commonly used to inspect pipelines, cables, and other sub-sea infrastructure. These ROVs provide critical data on the condition and integrity of underwater assets. Their detailed visual data helps ensure the safety and reliability of sub-sea systems.
The emergence of AUVs and ROVs has transformed marine and offshore engineering. These underwater vehicles, each with its unique capabilities, offer innovative solutions for exploring, monitoring, and managing underwater environments. From scientific research to commercial applications, AUVs and ROVs have become indispensable tools in advancing our understanding of the oceans and supporting sustainable marine activities.
