OCEAN BOTICS - This compact unit is light enough to manhandle onboard and small enough to stow away without too much additional designing of vessels like the Elizabeth Swann. John Storm would like this unit.

 

 

 

 

Unlike submersibles, ROVs are unmanned, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform above the area of operation, or on proximate land.

 

Smaller ROVs are perfect survey tools for amateur or professional treasure hunters, like Safiya Sabuka in the fictional search for Cleopatra's mummy.

 

ROVs or UUVs (Unmanned Underwater Vessels) are common in deepwater industries such as offshore hydrocarbon extraction oil rigs. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a Tether Management System (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minimized.

The umbilical cable is an armored cable that contains a group of electrical conductors and fiber optics that carry electric power, video, and data signals between the operator and the TMS. Where used, the TMS then relays the signals and power for the ROV down the tether cable. Once at the ROV, the electric power is distributed between the components of the ROV. However, in high-power applications, most of the electric power drives a high-power electric motor which drives a hydraulic pump. The pump is then used for propulsion and to power equipment such as torque tools and manipulator arms where electric motors would be too difficult to implement subsea. Most ROVs are equipped with at least a video camera and lights.

Additional equipment is commonly added to expand the vehicle's capabilities. These may include sonars, magnetometers, a still camera, a manipulator or cutting arm, water samplers, and instruments that measure water clarity, water temperature, water density, sound velocity, and light penetration.

ROVs range in size from that of a small computer to being as large as a small truck. Larger ROVs are very heavy and need other equipment such as a winch to put them over the side of a ship and into the water.

While using ROVs eliminates the “human presence” in the water, in most cases, ROV operations are simpler and safer to conduct than any type of occupied-submersible or diving operation because operators can stay dry and warm, or safely on ship decks. ROVs allow underwater investigation in areas that are too deep for humans to safely dive themselves. And ROVs can stay underwater much longer than a human diver, without decompression, making more time for exploration.

 

 

 

 

ROVs are used extensively by the scientific community to study the ocean. A number of deep sea animals and plants have been discovered or studied in their natural environment through the use of ROVs; examples include the jellyfish Stellamedusa ventana and the eel-like halosaurs. In the US, cutting edge work is done at several public and private oceanographic institutions, including the Monterey Bay Aquarium Research Institute (MBARI), the Woods Hole Oceanographic Institution (WHOI) (with Nereus), and the University of Rhode Island / Institute for Exploration (URI/IFE).

Science ROVs take many shapes and sizes. Since good video footage is a core component of most deep-sea scientific research, research ROVs tend to be outfitted with high-output lighting systems and broadcast quality cameras. Depending on the research being conducted, a science ROV will be equipped with various sampling devices and sensors. Many of these devices are one-of-a-kind, state-of-the-art experimental components that have been configured to work in the extreme environment of the deep ocean. Science ROVs also incorporate a good deal of technology that has been developed for the commercial ROV sector, such as hydraulic manipulators and highly accurate subsea navigation systems. They are also used for underwater archaeology projects such as the Mardi Gras Shipwreck Project in the Gulf of Mexico and the CoMAS project in the Mediterranean Sea.

While there are many interesting and unique science ROVs, there are a few larger high-end systems that are worth taking a look at. MBARI's Tiburon vehicle cost over $6 million US dollars to develop and is used primarily for midwater and hydrothermal research on the West Coast of the US. WHOI's Jason system has made many significant contributions to deep-sea oceanographic research and continues to work all over the globe. URI/IFE's Hercules ROV is one of the first science ROVs to fully incorporate a hydraulic propulsion system and is uniquely outfitted to survey and excavate ancient and modern shipwrecks. The Canadian Scientific Submersible Facility ROPOS system is continually used by several leading ocean sciences institutions and universities for challenging tasks such as deep-sea vents recovery and exploration to the maintenance and deployment of ocean observatories.

 

 

 

 

 

 

1953 POODLE - The first ROV ever built was the Poodle made in 1953 by Dimitri Rebikoff, a French pioneer in dive equipment and photography. The Poodle was an unmanned adaptation of Dimitri's dive scooter with a tether and surface controls.

THE MAIN COMPONENTS OF AN ROV

Frame. The frame provides a structure to attach the thrusters, camera, lights, tether, and other components of the ROV. It is the most important part of any ROV design. Most ROVs are built with an open rectangular frame that makes it easy to build and modify, but some ROVs are built with highly specialized frames to reduce drag, improve appearance, or perform a special mission.

 

Thrusters. The thrusters are electrically or hydraulically powered propellers used to maneuver the vehicle. There are almost always multiple thrusters to provide movement in multiple directions.

Tether. Nearly all ROVs have a tether that carries electrical power and/or signals to the surface so that the pilot can control the vehicle and see the camera. Radio waves don’t travel far through water, so it’s not possible to operate an ROV with modern wireless technology. There are acoustic and optical modem technologies that may someday enable wireless operation.

Pilot Controls. The surface controls can range from something that looks like the control room for a spaceship to something as simple as a smartphone, or and Xbox game controller. The surface controls provide a physical interface for the pilot to control the vehicle and a display of feedback from the vehicle including the camera view.

Camera. Since the vehicle travels deep underwater, the only view that the drone pilot has is through the onboard camera, which must be able to provide an image with low-latency.

Lights. The lights provide illumination for the camera (hence operator) to see underwater. Sunlight disappears rapidly underwater and many ROV missions occur at depths that are normally in complete darkness.
