The
LBV1502 line of ROVs
brings a whole new meaning to high performance small ROVs.
Equipped with more standard features than any other small ROV
the LBV is in a class of its own. Designed from years of experience
and knowledge the LBV is a proven underwater inspection tool.
 Perfect Balance
The LBV1502 system
is the perfect balance between compact size, ideal mass, powerful thrusters
and small diameter umbilical. Understanding that the umbilical represents
the most significant impact on drag to a ROV, the LBV is supplied with
the incredibly small diameter umbilical of 7.6mm. Adding to the
impressive umbilical are the very powerful thrusters, able to pull the
umbilical with ease.
What
makes LBV even more exceptional is the ideal mass in relation
to the umbilical and thrusters. It is one thing to be able to
pull the umbilical, but once power is released the LBV is able
to maintain a stable position without excessive influence from
the umbilical. Other small ROVs have more umbilical drag and
less power, less power and lower mass or all of the above making
it very difficult to maintain a stable position in conditions
less than perfect. Often referred to as "Tail wagging the dog
syndrome".
LBV
- a small ROV controlled by the operator not the umbilical.
 Performance Driven
Taking small ROV
performance to the next level are the very powerful thrusters.
Not content with just three thrusters LBV is fitted with four.
Two forward, one vertical and one lateral. Movement
is possible forward, reverse, rotate, vertical and lateral. Adding
the fourth thruster (lateral) greatly improves control and inspection
capabilities. Imagine survey the hull of a vessel where you approach
the side of the hull. Now you wish to scan the hull from the bow
to the stern. Unless your ROV is fitted with a lateral thruster
or panning camera it will be difficult. With LBV you simply move
the joystick laterally and glide along the hull of the vessel carefully
capturing the important video footage.
Adding
to the practical thruster layout is the actual thruster performance
data. Each
thruster has an impressive Bollard thrust of 2.9kgf (6.4lbs).
The two forward thrusters provide a combined forward thrust of
5.5kgf (12.13lbs) propelling the vehicle along the surface at
2.75 knots. With an in air weight of 11kg the combination of
power and compact dimensions give an outstanding power to weight
ratio.
 Design Superiority
One of the most
important aspects of a small ROV is its umbilical. Often overlooked or
misunderstood the umbilical can represent the biggest obstacle in a ROV
system - until LBV. Where misunderstandings happen are in the impact
on drag of the umbilical versus the ROV itself.
When
LBV was originally designed it was understood that it had to
have the smallest possible umbilical diameter, to keep drag to
a minimum. The revolutionary design resulted in a nominal 7.6mm
diameter which is 24% less than LBV's nearest competitor and
if that is not enough LBV has 75% more power than the same competitor.
Reduced
drag is not the only benefit of the LBV umbilical, weight is
also a key factor. The LBV's umbilical is 55% lighter than its
10mm competitor. Add the weight of the LBV, umbilical and control
console and the system weight is less than smaller ROVs.
27 0¼ High Resolution Video
Each LBV1502 is fitted with a high resolution
color camera as standard. The super HAD chip has 570 lines of
resolution, only requires 0.3 lux of light, has a 3.6mm lens,
auto iris and manual focus. Total control with exceptional video
quality.
The
camera is mounted to a rotating chassis to provide 270¼ field
of vision. Simply pressing the tilt keys on the hand controller
enables the operator to adjust the camera angle.
Tracking
the camera is a 50 watt quartz halogen lamp that has a manually
variable intensity control. Fixed lights are not much good
if you want to look straight up or straight down.
Fitted
to the LBV150S2 and the LBV150L2 is
a secondary forward camera. The second camera is an ultra low
light Black & White camera. On the controller is a camera
button used to switch between the cameras. Use the B/W when
water conditions are turbid.
 Intuitive
Operation
The LBV150S2 and LBV150L2 systems
come complete with the convenient and rugged case fitted with
the surface power supply and hand controller. Simply open the
lid, plug into mains power and connect the umbilical. Fast and
efficient. The lower portion contains the surface power supply
and the hand controller. Using a coiled cable the hand controller
can be removed depending on preference.
The LBV150B2 system
utilizes the separate hand controller and surface power supply
system.
 All
the controls for LBV are via an ergonomically designed hand
controller. Whether the operator is new or experienced operating
LBV is simple and intuitive. With all
the controls at your finger tips you can focus on the capturing
of video and not the fumbling around with awkward controls.
Functions include: all thruster controls, variable thruster control,
auto functions, trim, camera controls, light controls, overlay,
accessories and all programming.
Surface Power Supply - Safe
LBV has minimal
power requirements. Depending on the system input power is from
650 to 1,000 watts. All systems have an international power supply
with acceptable inputs of 100-130VAC or 200-240VAC 50/60 Hz.
The question sometimes arises regarding safety. LBV is designed
with safety in mind. Protecting those around are safety features as outlined in the "Code
of Practice for Safe use of Electricity in Water" as published
by the Association of Diving Contractors. Such features include
isolated power supply, ground fault interrupter, line insulation
monitor, residual current monitor and leak detectors. LBV is
safe to operate.
 On
screen Information Overlay
Each LBV system
is supplied with an on screen information overlay. The critical
information displayed aids the operator in navigation, setup
and control. With the information displayed right on the video
screen there is no need to look away ensuring you don't lose
track of your position. Also, the overlay position can be changed
from bottom to top or even off completely.
 Highly Portable
The entire LBV1502 system
is easily transported in the included transit cases. In one
case the LBV, video cables and documentation are stored in
custom closed cell foam. The other case houses the umbilical,
surface power supply, control console, spares kit and spare
thruster assembly. Again the second case is fitted with closed
cell foam.
Each
case is fully waterproof when closed and even floats. There
is a retractable handle on each including wheels. The cases
can be carried on any commercial airplane and often without
excess baggage fees.
 Backup
As rugged as LBV
may be there are requirements for maintenance. Also, due
to the rugged conditions in which an ROV is operated there
will with out a doubt be times when minor repairs are necessary.
With each LBV system sold a spares and tool kit is supplied.
All the tools needed to
do virtually any repair are included.
The
spares consist of a lamp, props, fasteners, seals, gel
lube and more. Located on our website are extensive procedures
manuals walking you through each operation. Also, included
with the spares is a complete thruster assembly that can
be used in any of the four locations.
