Demystifying ROV's: The Pioneers of Underwater Exploration

In the realm of maritime exploration and offshore work, the term ROV often comes up. But what does ROV stand for, what are ROV's used for, whats the ROV logo, isn't it an ROV submarine, well these are just some of the questions we have been receiving recently in our live chats?
 
Well this stands for Remotely Operated Vehicle. These devices are like submarines controlled by trained and certified vehicle pilots from a ship, made to handle the tough conditions of the deep sea. They have transformed the way we explore and understand our oceans, proving to be a cost-effective and safe solution for various maritime tasks​​.
 
There are a broad range of remotely operated underwater vehicles. These can be classified into different types of ROVs, including work-class, observation-class, and more. Work-class ROV's are robust and heavy-duty, often used for intense underwater tasks such as drilling support, construction, and salvage operations. On the other hand, smaller vehicles like underwater drones or ROV’s, like the observation class, are used for less demanding tasks such as inspection and surveying.
 
An ROV system typically consists of the vehicle itself, a tether management system, and an operator control unit stationed on the surface vessel. The underwater remote operated vehicle is connected to the surface control unit by a tether, which allows for data and power transmission between the two.
 
A typical vehicle, consists of a frame that houses the components, thrusters for mobility, a HD video camera for visual feedback, and often additional sensors for data collection. Some of the more sophisticated underwater vehicles might even include a manipulator arm for interacting with the underwater environment. There are also Doppler Velocity Log (DVL), which are amazing at accurately estimating the speed and direction of movement. There can be multibeam sonars and also an underwater GPS system known as a ultra-short baseline, USBL. All these components are designed to withstand the water conditions that they will be exposed to during their operation.
 
The technological development of ROV’s has been quite impressive. One of the key areas of innovation is the battery life of these devices. Enhanced battery life allows underwater vehicles to undertake longer missions and reach greater depths. This is particularly important for deep water vehicle’s, which need to navigate through the challenging water column and reach the ocean floor.
ROV technology has been instrumental in a variety of applications, from marine research to offshore oil and gas operations. For instance, marine ROV’s have been at the forefront of the NOAA Ocean Exploration program, with the NOAA ship Okeanos Explorer using ROV’s for deep-sea exploration. The use of underwater vehicles has revolutionized our understanding of the marine ecosystem and has contributed to the discovery of new marine species and underwater geological formations.
 
In offshore operations, these vehicles play a pivotal role. They assist in drilling, construction, and maintenance work. Underwater vehicles have an excellent track record in performing delicate tasks, from turning valves and operating tools to connecting pipelines in the challenging offshore environment. This has made them an integral part of ROV-work in the offshore industry.
​
The future of ROV’s is also quite promising. New advancements in manufacturing and ROV technology are continuously being developed. For instance, some ROV’s are being equipped with advanced AI capabilities to perform autonomous operations. This not only increases the efficiency of the operations but also reduces the risk to human operators.
​
That being said, ROV’s, or remotely operated vehicles, have revolutionized the way we explore and operate in our oceans. From marine research to offshore operations, these underwater vehicles have proven their worth time and time again. They represent a shining example of how technological development can push the boundaries of what is possible, opening new frontiers for exploration and making the ocean's depths more accessible and comprehensible than ever before.
