TIGER
ROV - Compact and affordable
Authorized
sales agents for Tiger ROVS
THE
TIGER is widely regarded internationally as the standard observation
and inspection ROV for operations to depths of 1000 metres in the offshore
oil and gas industry. Its performance in strong currents, excellent
handling and manoeuvrability are unsurpassed.
A
Tiger can be operated free swimming with up to 450 metres of
umbilical or from a Type 2 or Type 5 TMS system to its full working
depth

Tigers are open frame construction providing greater
scope to fit additional accessories and more capable manipulators than
'eyeball' ROVs. This open frame construction also allows the horizontal
thrusters to be mounted in the most efficient vectored arrangement providing
far greater thrust in both forward and lateral directions than earlier
axial and lateral thruster combinations.
A basic ROV system
comprises the Vehicle, a Surface Control Unit a Hand Control Unit and
a Power Supply Unit.
The
surface Control unit and PSU can be supplied free standing or as a containerised
system. This Control Container can be Zone II rated or rated for safe
area operations. It is air conditioned as standard.
Free
swimming operations are possible with up to 450 metres of tether. For
operations with umbilical lengths greater than 450 metres it is necessary
to use a Tether Management System (TMS). This can either be the economical
Type 2 bale arm system providing an excursion range of 140 metres or
the superior Type 5 TMS which is a winch and slip ring arrangement.
The Type 5 TMS with its variable garage opening height provides ROV
excursions from the TMS of up to 240 metres.

Propulsion
All Tiger ROVs feature brushless DC thrusters which, apart from having
the greatest power density, have integrated drive electronics with velocity
feedback for precise and rapid thrust control. These thrusters are interfaced
to a fast PID control system and a solid-state rate gyro for enhanced
azimuth stability. These essential building blocks enable provide superior
control and response from their powerful ROVs and set them apart from
the competition.
Four
vectored horizontal and one vertical SM4M brushless DC thrusters propel
Tiger and provide full three-dimensional control.
Chassis
The 100% modular chassis is manufactured in polypropylene. This extremely
rugged material is totally maintenance free, non corroding and self
supporting in seawater. Additional equipment can be bolted directly
to chassis members.
Pressure
Housings
All housings are machined from 6082 marine grade aluminium and hard
anodised black. The main electronics pod is fitted with a water ingress
alarm that displays on the video overlay if activated.
Connectors
Tiger's range of 316 stainless steel connectors are generally used throughout.
Buoyancy
Is provided by a single moulded syntactic foam buoyancy block with apertures
provided for a sonar head and a transponder or responder.
Control
System & Video Overlay
A 16 bit digital control system provides easy interfacing of ancillary
equipment by the operator. The comprehensive video overlay is fitted
as standard providing digital and analogue compass rose, tilt icon,
date time group, depth (metric or imperial), CP value, pre-titled and
free text pages. Vehicle data may be exported to a client's Survey or
Navigation computer via a PC using the Telemetry Monitor Unit that is
provided as part of the standard Tiger spares kit..
Navigation
Compass
A sensitive flux-gate compass unit with solid state rate sensor is incorporated
for enhanced azimuth stability.
Accuracy: ± 1°
Resolution: 0.351°
Up-date rate: 98mS
Depth
Sensor
Electronic unit in its own separate housing. Accuracy ± 0.1%
of full scale deflection.
Auto-pilot and Thruster Trim Functions
Full automatic pilot is provided for depth and heading. Thruster trims
are provided on the hand control unit.
Tilt
System
The cameras are mounted on a tilt platform providing ±90°
of tilt. The tilt mechanism is fitted with a positional feedback potentiometer
and camera tilt angle is displayed on the video overlay.
Lighting
Two individually fused 150W lamps are provided with remote brilliance
control. Both lamps are positioned on the camera tilt unit to follow
the camera tilt angle for optimum scene illumination.
Video
System
Two simultaneous video channels are provided. Video transmission is
via screened twisted pairs from the vehicle to the TMS and a single
fibre-optic from the TMS to the surface. A 14" colour monitor PAL/NTSC
is supplied as standard.
Surface
Control Unit
This unit contains all of the vehicle system surface control electronics,
TMS control and surface outlets for ancillary equipment. It is 19"
rack mountable and is supplied in its own case
