Seaeye Falcon - Options and Accessories
At Seaeye we are constantly looking at new ways
to enhance the capability of our vehicles by developing useful
tools and accessory interfaces that can be added to the basic
systems. These are developed as much from customer input as
from our own operational experience.
The following accessories are currently available
for your Seaeye Falcon. Others are in development and will
be added to this list as they are proven in the field:
Running Lock Latch - for safe launch and recovery
The Falcon Running Lock Latch System comprises a Bullet Assembly, that replaces the vehicle's standard umbilical attachment point, and a Running Lock Latch Assembly that can be used in combination with a lifting winch to launch and recover Falcon ROVs without putting strain on the ROV umbilical. This is ideal for use on oil rigs or from other elevated launch sites!
Some operators leave the lock latch in the water following release of the ROV to act as a clump weight below the splash zone helping to keep the umbilical clear of the ship's propellers and thrusters.

Single Function, 3 Jaw Manipulator & Rope
Cutter - all in one useful tool!
|Closed with cutter blade covered
||Opening exposes the blade &
traps the rope..
|to make the cut
This clever single function manipulator has three,
100 mm stainless steel jaws enabling vertical or horizontal
objects to be grasped without the need of the rotate function
required with traditional two jaw manipulators.
Particularly useful for freeing trapped umbilicals,
light recovery tasks or attaching a line, we recommend this
device as the first choice of accessory to add to the vehicle.
This tool can also be used to cut 9 mm diameter
rope with the simple installation of a craft or 'Stanley Knife'
blade that remains fully protected while the jaws are closed.
Open and close of the jaws is controlled on the Falcon hand
5 Function Manipulator Skid
|5 Function manipulator skid...
||mounted under Seaeye Falcon
The Falcon 5 function manipulator skid contains
a small hydraulic power pack, a pressure compensation bladder
and valve pack fitted with 5 bi-directional solenoid valves
to operate each of the manipulator's 5 functions. Attachment
to and removal from the vehicle is very quick with power and
control supplied from the ROV to the skid via a single connector.
Additional buoyancy is built into the skid to compensate for
its additional weight.
functions are operated by a dedicated hand controller
and include 90 degree shoulder rotate and 180 degree jaw
rotate. The jaws incorporate a ¼ inch rope cutter
and the arm has a lift capacity of 10 kg at full reach.
Maximum torque is 8Nm with a system pressure of 80 bar.

Wire Rope Cutter Skid
|Falcon Wire Rope Cutter Skid
This hydraulically powered, skid mounted cutter
is capable of cutting up to 19 mm diameter polypropylene rope
or 12 mm stainless steel wire rope. It is a 3 function device
providing 180 degree shoulder rotate, an elbow function and
operation of the ram-type cutter blade.
Sonar is the underwater equivalent of radar and
is used to increase the detection range of subsea objects
far beyond the visual range of the ROV's camera. This significantly
adds to the operational capability of any ROV particularly
in search and survey operations as well as for obstacle avoidance.
It can also be a great help to the ROV pilot in orientating
himself and the ROV to its surroundings, particularly in poor
visibility. In extreme conditions it may be impossible to
usefully operate an ROV without sonar.
The detection range of sonar depends on ambient
water conditions, the type of seabed, the size of the object
and the frequency of the sonar head. Lower frequency sonars
provide greater detection range but at the expense of image
resolution. Higher frequency sonars have lower detection ranges
but greater resolution. Some sonars have a fixed frequency
while others are tuneable or have dual, selectable frequencies.
The sonar head is installed on the vehicle with
the transducer protected by a polypropylene guard. The sonar
data is transmitted to the surface processor through a spare
screened twisted pair in the ROV umbilical and the sonar image
is displayed on a monitor housed in a 19 inch racked transit
case with the sonar processor. Some manufacturers offer sonar
processing software that can be installed on the clients own
PC as an alternative to using their surface sonar processor.

||Sonar surface processor and monitor
Falcon accepts most manufacturers' 24 or 48 volt
DC sonars. We are happy to assist with the selection of the
most appropriate system for your requirements.
Falcon surface control unit, hand controller
and sonar surface unit
Falcon is provided with a high-resolution NTSC
or PAL colour CCD camera as standard. A second camera can
be added if required. A toggle switch is provided on the Falcon
hand controller to select between cameras A and B.
Alternative or additional camera options from various manufacturers
- Low light black and white cameras
- Pan and Tilt cameras
- Zoom cameras
CP probes are used to measure the cathodic potential of subsea
The Seaeye Falcon can accommodate either a 'contact'
or 'proximity' probe as the operation requires. A contact
probe is illustrated above.
The measured CP voltage is displayed on the Falcon Surface
Unit video overlay.
|Cleaning brush kit
||Cleaning brush installed
Powered by a Falcon thruster motor, this accessory
is ideal for spot cleaning before taking CP readings, wall
thickness measurements or the use of a flooded member detector
(FMD). It is not intended for cleaning large areas of subsea
structures for which a larger ROV like the Seaeye Lynx or
Seaeye Panther Plus fitted with a heavy duty cleaning brush
would be more appropriate.

results achieved by DNT Offshore in Italy who used their Falcon
to clean welds on an oil rig in preparation for non destructive

Ultra Sonic Thickness Gauge
Ultrasonic thickness gauges use acoustic echo
techniques to determine the thickness of structures and materials
underwater. This involves the generation of a sound wave,
and the measurement of time taken for a far side echo's to
pass through the material of the structure under test.
Measurement data is transferred from the ROV
mounted probe up to the surface via the Falcon's umbilical
cable. Dedicated software displays the measurements and logs
all test data.
Typical applications include deepwater pipeline
inspection, ship inspections, lock gate, pier and piling inspections.
Umbilical Hand Winch
In order to avoid twisting and kinking it is
usual to coil the ROV umbilical in a figure of 8 on deck or
over cow horns mounted on a bulkhead and then pay out and
recover the umbilical by hand.
The use of an umbilical winch is a more convenient and space
Falcon umbilical hand winch &
||600 mm excluding handle
||31 kg excluding umbilical
||450 m Falcon umbilical
The Series 5 umbilical hand winch has a capacity
of 450 metres of 13 mm umbilical. A slip ring is included
so that umbilical can be reeled in and out during ROV flying
operations. With a frame and drummed constructed of polypropylene
with aluminium spacer bars, this new IP68 rated hand winch
is 15 kilos lighter than previous units.
IP68 Waterproof Surface Control Equipment
IP68 rating is an internationally recognised
standard that certifies equipment against the ingress of dust
(solids) and water (liquids). The IP68 Falcon surface equipment
is totally protected from any ingress of water during prolonged
periods of immersion that can be encountered in hostile maritime
An additional benefit of the IP68 Surface Equipment is lower
weight and enhanced portability. By using the IP68 option
less space is required for the surface equipment, deployment
and transit is simplified, creating a more versatile package.
For example, in conjunction with a small generator, the entire
system can be deployed in an exposed RIB or a light launch.
|IP68 Surface Equipment
||IP68 Equipment Packed
The IP68 Seaeye Falcon surface equipment comprises
of the following two pieces of equipment:
IP68 Surface control unit:
This is built into a rugged case with an integral
daylight readable video display and overlay. All of the vehicle
controls normally fitted in the hand controller for a standard
Falcon are incorporated into this unit including the joystick.
IP68 Power supply unit:
This compact power supply saves space, yet retains
the full functionality of the standard power supply unit.
It is also fully water proofed to the IP68 standard.
