ROV Is Widely Used In Marine Science Investigation
Oct 11, 2017

ROV is a convenient, lightweight and stable underwater operating system that is easy to operate according to intuitive navigational controls. The steelhead can be placed very lightly on the dock and on the ship without even needing a hoist or crane.

The ROV is widely used in marine science survey in the world.

Compared with other deep-sea submersibles, ROV has the advantages of long working time, strong working ability, large load capacity, no personal danger accident of workers, ROV and the development of optical fiber technology, which can transmit information and control instructions in real time through the ROV of the umbilical cord cable. The operator can control the movement of the ROV body in the underwater operation in a real-time, ROV lightweight and flexible manner in the Master Ship Deck control room, and has an irreplaceable role in the deep-sea operations, and has a ROV footprint in different sea depths.

According to Unols's report, the current international commercial ROV basic work in 3000 meters shallow, but to complete the ocean exploration and scientific research, ROV need to work more than 3500 meters in depth, and has a deep sea support for the professional design, so the test with ROV is a large depth ROV. At present, the use of deep-sea ROV detection platform, it can realize the marine science investigation of the Sea of all seas, ROV and with the function of ROV in the Ocean Department is more and more remarkable, both the domestic and the world's main marine research institutions are equipped with ROV for scientific investigation, and ROV is the most mature and widely used technology at present, The most economical and practical type of submersible. Table 1 shows the ROV of the major marine research institutions in the world.

The general structure of the ROV is generally supported by the parent ship (deck control room), the power distribution system, the umbilical cord and the retractable system, the ROV body and other components. ROV tend to meet different functional needs depending on the mission and purpose of the oceanographic survey, thus maintaining a flexible design, in particular the need to retain the future upgrade capabilities, ROV so most ROV are developed by the marine research institutions on their own requirements to achieve flexible and versatile functional requirements, But there are also some marine research institutions to buy commercial ROV to third-party manufacturers, but such ROV generally retain a wealth of mechanical, electrical and hydraulic power and other interfaces to meet the user expansion of energy requirements. Therefore, each set of ROV in the ROV ontology according to functional requirements will be different and have their own characteristics.

One of the most important functions of ROV in marine science investigation is to observe the seabed, so video and illumination as ROV's "eyes" are very important, ROV is generally to be configured from Multi-angle, to meet the ROV of near-Sea observation and ROV State Monitoring, And ROV is basically configured with one or more high-definition cameras, and is installed on the cloud platform. ROV In order to get a clear picture of the seabed, ROV has a camera with camera function and a flashlight for photographic purposes.

ROV, as a platform for scientific research and detection tools, has a wealth of hydraulic and electrical expansion interfaces for equipment and instrumentation in the ocean section, such as Rosub $number ROV configuration with Reson 7,125 multi-beam systems, CTD sensors, dissolved oxygen sensors 3180, water intake, Methane sensors, etc. Victor $number ROV is also equipped with Reson 7,125 multi-beam system, ROV but also with Otus wide-angle camera, sea bird SBE-CTD sensor and water receiver, magnetometer, Simrad EK60 echo detector and shallow profiler, such as expansion and equipment.

ROV has been an important tool and ocean research Platform for exploring the mysteries of the ocean, which can be observed, tested, sampled, scientifically instrumented, laid and recycled, ROV and under various seabed missions such as submarine cables, for marine science, Marine Geology, Scientific research on marine physics and Marine chemistry and resource exploration plays an increasingly important role.

One of the most important functions of ROV in marine science investigation is to be able to observe the objects of the seabed at close range, the general ROV configuration of the video flexible and diverse, compared to the manned Submersible observation window can obtain a greater view, and provide high-definition video and images, so that researchers on the seabed of the bottom of the characteristics of the environment, The biological condition and so on have the more intuitive impression, facilitates carries on the correlation research to the sea area.
