The new Shark G2R from Rovotics is a reliable and cost-efficient Remotely Operated Vehicle (ROV) designed for surveying various subsea assets.
In order to achieve the professional finish needed for the vehicles, DIAB says it provided Rovotics with complete, 5 axis CNC processed and painted kit just to bolt-in-place.
DIAB explains that a Remotely Operated Vehicle (ROV) is an underwater vehicle controlled from the surface. Being highly manoeuvrable and able to provide video and still camera imagery along with information from various other sensors it allows observing, inspecting, mapping and measuring the condition of subsea assets. ROVs were first developed for industrial purposes, such as inspection of pipelines and testing the structure of offshore platforms. However, today ROVs are used for many applications, many of them scientific.
ROVs are usually designed to have positive buoyancy, i.e. to float on the surface, to ensure they will return to the surface if a power failure occurs. DIAB explains that the desired buoyancy and stability are achieved using syntactic foam and an accurate prediction of net buoyancy is invaluable in the design process. Without it, the designer risks making guesses that may require time-consuming and expensive alterations or complete rebuilds.
According to DIAB, the Shark G2R is a brand new ROV designed and manufactured by Rovotics. Headquartered in the United Arab Emirates, Rovotics specialise in cutting edge, highly dependable ROVs and components including cameras, lights, junction boxes, subsea housings and CP equipment. With a length of 1.1 meters and weighing 160 kg, the Shark G2R is a reliable seahorse. It can carry up to 35 kg payload and operate down to 500 meters depth. Equipped with six thrusters, it can reach speeds up to 3 knots.
DIAB says it was supplied with a 2D drawing, which was converted into a 3D-model in order to develop the programming for the 5-axis CNC machine. DIAB also helped provide all the necessary buoyancy calculations to ensure that the ROV performed to design expectations.
"We received the desired buoyancy on time and we are currently exhibiting the ROV in Dubai. We are very happy with the finish of the buoyancy. It looks very good,” says Javier Gonzalez at Rovotics.
