What is a Work Class ROV?

Underwater ROVs have become a valuable resource in various fields relating to the marine industry. The ROVs are used to perform a multitude of tasks, and thus there are different classifications in them depending on the work they perform. Work class ROVs are one of the significant underwater ROVs classes widely used in the marine industry.

What is a work class ROV?

Work class underwater ROVs are used for explorations and inspections in depths of the ocean that aren’t safe for the divers. Work class ROVs are primarily used by offshore energy organizations and other industries that require deep-sea diving.

The work class ROVs are usually large compared to the observation class ROVs since the former includes space that carries cameras, sonars, sensors, manipulators, and other equipment needed to perform the particular job. Work class ROVs usually have a multiplexing capability which means that you can operate the additional sensors and tools without hardwiring them to the umbilical system.

The observation class ROVs are usually used to explore small spaces with shallow depths like lakes, rivers, etc. On the other hand, the work class ROVs are powered electrically and hydraulically, making it possible to carry out severe sub sea work at deeper depths. The manipulators present in the ROVs air the drilling and related works and thus are primarily used in the offshore construction and pipeline inspection sector.

Heavy Work class underwater ROVs are the advanced version of the work class ROVs, and these can perform tasks at an impressive depth of up to 10,000 feet underwater. These heavy work class ROVs' payload and lift capacities are much higher than the usual work class ROVs.

Components used in the ROVs

Underwater ROVs can be viewed as miniature submarines but without an operator inside. The ROVs are operated through a wired or wireless connection from a distance. Here are the components that make an ROV.

1. Frame

The frame supports all the systems of the ROV, and work class ROVs usually come with larger frames. These frames are generally lightweight materials to prevent excessive weight and lag during movement. The structure is also designed to withstand impacts during operation and avoid damage to the internal components.

2. Motherboard and processing unit

This is the primary operating unit where the commands from the operator are converted into physical outfits. Depending on the type of task, wired or wireless ROVs are used. For example, wired ROVs might be best for explorations at sea surface levels, while wireless ROVs might be best for wreckage inspection and such. The electrical systems are usually encased in insulated coatings and waterproof containers to avoid corrosion and electrical issues underwater.

3. Sensors

Sensors are the major components needed for the ROV to work correctly. The ROVs might be fitted with cameras, temperature sensors, system sensors, and more, depending on their type.

Cameras are one of the basic needs for underwater ROVs and collecting data. Most work class ROVs come with HD cameras that help the operator navigate better and understand the surroundings. The missions are often recorded and are used as case studies.

Depth gauges in the ROVs help determine the depth until the ROV can explore and ensure that it does not descend into zones that it cannot handle.

Temperature sensors are used to gauge the temperature at a particular area, temperature changes at various subsea regions, and detect subsea thermal vents.

Additional provisions are added as per requests like a thermal imagery camera, RADAR, navigational software, and more.
