THE SEAEYE 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 Seaeye Tiger can be operated free swimming with up to 450 metres of umbilical or from a Type 2 TMS system to its full working depth.

Seaeye 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 Seaeye Tether Management System (TMS). This is achieved thanks to a TMS Type 2 bale arm system providing an excursion range of 140 metres.

Seaeye Tiger and its TMS Type 2

A skid mounted 'A' frame and lifting winch with 1100 metres of armoured lift umbilical is offered as a compact combined unit to launch and recover a TMS garaged Seaeye Tiger. Alternatively an articulated crane and winch unit can be offered mounted on a gravity base.

Articulated crane, winch and gravity base

These options can be offered rated for hazardous area Zone II operations or for 'safe area' operations and are known as a 'LARS' or Launch And Recovery System. Alternatively you may have your own crane available and may only require the lifting winch and armoured umbilical with an umbilical sheave and a lock-latch release mechanism and vehicle bullet for launch and recovery.

Propulsion
All Seaeye 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 Saab Seaeye to provide superior control and response from their powerful ROVs and set them apart from the competition.

Four vectored horizontal and one vertical Seaeye 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
Seaeye'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 Seaeye 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 Seaeye Telemetry Monitor Unit that is provided as part of the standard Seaeye Tiger spares kit..

Navigation Compass
A sensitive flux-gate compass unit with solid state rate sensor is incorporated for enhanced azimuth stability.

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 Seaeye 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.

LED lights providing exceptional illumination and durability are available.

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.
