An ROV is a remotely operated underwater vehicle that is tethered to another vessel. Since people are not on board ROVs, they are operated remotely by workers on the vessel. The benefits of using ROVs are that they can be used for exploring underwater that is very deep as underwater that contains harsh conditions such as strong currents. The United States Navy created the first ROV in the 1960s when it created the CURV, which was the name given to a Cable Controlled Underwater Recovery Vehicle. One of the main things this vehicle was used for was to pick up objects off of the ocean floor. In the 1980s the ROVs became even more useful, because they started being used in the by the oil industry to reach areas of offshore oil fields that could not be reached by human divers.
Today, the world's energy needs are higher than ever, so the need for ROVs are greater than ever. The benefits of an ROV, which is essentially an an oil field companies, are numerous for not only the oil and gas industry, but for other energy industries such as the wind and nuclear industries, which have much critical work that is conducted underwater. Whether it is for emergency repair work or just for routine maintenance and inspections, it is often safer as well as more economical to use ROVs than to try to send humans under the water to perform the work. Even during times when underwater human divers are needed to do work ROVs can still be vital because they can provide an extra measure of safety during a divers voyage under the water.
Currently, there are many different types of ROVs and several of them can be viewed at deeptrekker. There are some features that every good yet affordable ROV will contain. For example a great ROV will have a camera on it with the ability to rotate 270 degrees to do a thorough inspection of underwater items and infrastructures. In addition, an ROV will have a pitch system that will allow it to get into very tight spaces. This is critical because many small underwater spaces are far too dangerous for divers to access. In order to get underwater jobs done effectively, an ROV should have a long lasting battery life. Probably one of the most important aspect of an ROV is that it is built to last a long time. To withstand the harsh elements of water and especially salt water a quality ROV should be made of a strong aluminum and have a corrosion resistant coating on it.
