Remotely Operated Vehicle (ROV)

Deepvision ROV-Services


Deepvisions Remotely Operated Vehicle (ROV) system has been specifically configured to quickly and effectively perform advanced underwater imaging tasks. Our ROV system is a portable and cost effective advanced solution that can be deployed in minutes and operated by one person if necessary.

INFRASTRUCTURE:

Much of the world's crucial public infrastructure involves water. Potable water tanks, reservoirs, locks, dams, bridges, and culverts are aging everywhere, and scarce funding must be allocated carefully and efficiently to the most critical problems. In order to do this, regular detailed inspections are needed. Until the arrival of underwater robotics solutions such as our ROV, these inspections were often either done with expensive, dangerous solutions involving divers, or they weren't done at all. In many cases a ROV inspection can be done rapidly, safely, and very cost-effectively. The results – video and still images of specific problem areas – can be transmitted and presented to experts who can decide whether the asset is okay for now, whether further study is needed, or whether immediate action is necessary to protect the public.

Using the Deepvision ROV eliminates potential safety risks, and eliminates exposing divers to unsafe conditions. The agile and simple-to-pilot submersible can be equipped with up to 600 meters (2,000 ft) of tether. It captures high quality video and still images directly to the ROV computer’s hard drive - easy to access, edit, and deliver in popular video and image formats.

OFFSHORE OVERVIEW:

The offshore industry is one of the primary beneficiaries of small ROV evolution. In this market, there is a considerable history of ROVs that handle underwater work in deep water (greater than 300 meters) depth ratings, or the ability to carry heavy payload or tools. Larger "Work Class" ROVs that perform these feats are a multi-billion dollar industry that had developed to meet oil and gas exploration, production, and handling tasks.

However, many of the tasks assigned to work class ROVs – or human divers – is shallow (less than 300 meters) and involves searching, inspecting, or surveying underwater. These tasks are ideally suited to our ROV technology. Because our ROV is smaller, lighter, and consume very little power, it can be deployed from many different areas on rigs and ships. Since they have very little mass, it can be safely used on comparatively delicate machinery without fear of damage. Since deployment involves simply heaving the submersible by hand into the water, they can be deployed in sea states where using larger machines is too dangerous. And their smaller size means they can penetrate areas where other machines are too small.

You might think that the smaller size would mean less current handling. However, the thrust to weight ratio of the ROV is so large, the tether so small, and the design so hydrodynamic that this is not the case. In reality, our system can handle more current than most work class ROVs in the shallow areas in which they are deployed.

ROV MANIPULATOR ARM

The Manipulator Arm is one of the most useful tools in our toolbox. Its uses are unlimited - anything from untangling tether snags to collecting samples to recovering objects up to 45 kg (100 lb). As soon as you use it, you'll wonder how you ever got by without it.

The manipulator arm easily attaches to the ROV and lifts objects underwater by using the tether of the ROV. From the hand controller or control panel, you can open and close the jaws to a two-inch distance to retrieve items in confined or hazardous locations. The ROV's camera focuses in on the manipulator arm to provide a close view of the operation. When not needed, the manipulator arm can be easily removed in seconds.

ROV SONAR

Deevision’s ROV Sonar has been developed exclusively for our ROV.

Ideal for underwater detection and identification tasks in low or zero visibility conditions, the sonar provide both midrange detection and close-range identification capabilities from moving or stationary platforms.The sonar has a field-of-view (FOV) of 130° for high-performance, forward looking imaging.

ROV Metal Thickness Gauge

The Metal Thickness Gauge has been specifically designed to be mounted onto small observation ROVs. The gauge will allow the operator to carry out thickness measurements in areas that have previously been inaccessible using large ROVs or divers.

Dedicated software displays and logs the time, date and thickness readings on the basestation.
