An ROV is an unmanned underwater vehicle that is tethered and operated remotely, using sensors and tools to collect data, powered through an umbilical cable connecting it to the operator. ROVs come in different classes based on their tasks and capabilities, and are used widely for inspection, sampling, testing and mechanical work but face challenges from restrictions of movement and visualization as well as potential environmental impacts. Major ROV service companies operate large fleets of ROVs across the world on ongoing offshore and subsea projects.

3. ● A remotely operated underwater vehicle also
referred to as an ROV, is an underwater
vehicle that is unmanned and usually
tethered to the operator.
● The unmanned vehicle is similar to a robot,
which is fitted out with sensors and sampling
tools to collect various types of data.
About The ROV

4. ● A network of cables (umbilical) is utilized to
for power transfer to the vehicle and for
communication between it and its pilot.
● ROVs are incredibly complex and serve a
wide variety of purposes. From exploration
and unmanned expeditions to research and
sporting events, they can be found in a
diverse set of fields.
About The ROV

5. Intervenes faster, keep

effectively, reduces your
carbon footprint
Resident
Categorization of ROVs
General
These are specially built
to aid in light survey
tasks as these usually
bear a sonar unit.
Heavy Work Class
From deep water depths to
extreme lifting requirements,
increase efficiency and
decrease downtime
Trenching-Burial
Offers a 200-500 HP
range and can be utilized
till 6000 meters
Light Work Class
Reduces the
environmental impact of
work class ROVs
Observation
Enables reliable
completion of subsea
survey operations

6. Electrical systems
Mechanical structures
Mechanical systems is
propulsion, which is in the form
of miniature and specialized
marine propellers.
The electrical systems refer
to the wiring and circuitry
that make up the heart of
the ROV.
Components of ROV mechanism
Sensors and appendages
The most common equipment that
is fitted include cameras, depth
gauges, temperature sensors, and
internal system sensors.
Task-specific structures
Task-specific modifications
are what makes an ROV
customizable and usable in
a wide variety of fields.

9. ROV Operational goals
1. Visual inspection
• Inspection of underwater structures
• Observation of ongoing work tasks on subsea structures
• Biological observation
2. Different types of mechanical inspection
3. Non-destructive testing
4. Mechanical work
5. Biological sampling, water column and bottom

11. Flow characteristics for normal operations
1.Non-streamlined body
2.Low speed
3.Mostly turbulent flow due to separation on edges
4.Umbilical drag for operations at large depths
5.Complex flow due to interacting thrusters

13. Shortcomings
A restriction of free
movement.
Restriction
Difficult Visualization
It lacks human presence
which makes for executing
the visual surveying down in
the underwater difficult.
A high-power signal that can
be used to control ROVs
across a large distance is the
preferred design. However,
high power and frequency may
affect marine life.
