Seaeye Surveyor Plus ROV Systems are rated for 600 metre depths of operation and replace the earlier model Seaeye Surveyor ROVs. This up rated edition is fitted with ten Seaeye SM4 brushless DC thrusters, two of which are provided for vertical thrust and eight in vectored pairs for horizontal propulsion. The result is an incredibly powerful and agile vehicle with 125 kgf of forward thrust and 108 kgf of lateral power.

The Seaeye Surveyor Plus is ideally suited for survey applications as well as general observation and inspection duties.

GB Diving's Surveyor Plus fitted with VT TSS 440 Pipe Tracker working for Deep Ocean A/S in the Black Sea.

This ROV has ample payload to accommodate a full survey suite including a VT TSS 440 Pipe Tracker.

A basic ROV system comprises the Vehicle, a Surface Control Unit with a Hand Controller and a Power Supply Unit. The surface unit and PSU can be supplied free standing or as a containerised system. The Control Container can be Zone II rated or rated for safe area operations and is air conditioned as standard.

Free swimming operations are possible with up to 600 metres of polyurethane sheathed lifting umbilical. Alternatively, the Seaeye Surveyor Plus can be operated from a Seaeye Bale Arm or Type 5 winch and slip ring Tether Management System (TMS). For TMS operations it will be necessary to use an armoured lift umbilical for deployment of the garaged ROV.

A SUBCO owned Seaeye Surveyor Plus on hire to Stolt Offshore in Egypt with a TSS Pipe Tracker installed on the front of the vehicle and dual head profiling sonars fitted at the stern. A bathymetric system, ROV tracking system and obstacle avoidance sonar is also installed.

A skid mounted 'A' frame and lifting winch with 600 metres of armoured lift umbilical or 600 metres of polyurethane umbilical is offered as a compact combined unit to launch and recover a TMS garaged Seaeye Surveyor Plus or free swimming vehicle. Alternatively you may prefer the gravity based, marine knuckle boom crane and winch system illustrated. Either 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 appropriate umbilical with an umbilical sheave and a lock-latch release mechanism and vehicle bullet for launch and recovery.

Upgrade Kits are available to convert earlier Seaeye Surveyors to the current Surveyor Plus standard.

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.

Ten Seaeye SM4M thrusters are used to power the Seaeye Surveyor Plus in a configuration of eight vectored horizontal units and two vertical units. SURVEYOR PLUS is an extremely powerful and stable survey platform with full three dimensional control of the vehicle.

A particular benefit of the 'Plus' configuration of pairs of vectored thrusters and two vertical thrusters is the level of redundancy available. The power for the thrusters is split into two channels with each channel providing DC to one vertical thruster and 4 of the 8 horizontal thrusters. If a fault should develop on one channel it can be isolated allowing operations to continue at half power. If there is a failure in only one horizontal thruster the effect on vehicle performance and control will be barely noticeable.

The ROV chassis is manufactured in Polypropylene with hard anodised aluminium cross trays and a stainless steel lift frame. The extremely rugged chassis is totally maintenance free, non-corroding and self supporting in seawater. Additional equipment may be bolted directly to chassis members. Seaeye Marine was the first company to introduce polypropylene for the construction of ROV frames.

Pressure Housings
All pressure housings are machined from 6082 marine grade aluminium and hard anodised in black. A water ingress alarm system is fitted in the electronics pod.

The SEAEYE range of 316 stainless steel connectors are generally used throughout.

Two hydro-dynamically shaped blocks of closed cell polyurethane foam provide the vehicle's buoyancy. Additional buoyancy can be added if greater payload is required.

Control System
16 bit digital system provides easy interfacing of ancillary equipment by the operator. The comprehensive SEAEYE 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 the client's Survey or Navigation computer systems via the SEAEYE Telemetry Interface Unit in conjunction with a PC.

Typical Control Cabin Layout

Sensitive flux-gate compass unit with enhanced azimuth stability from a solid state rate sensor system:

Accuracy 1
Resolution 0.351
Up-date rate 80 mS

Depth Sensor
Separately housed electronic unit. Accuracy 0.1% of full scale deflection.

Automatic pilot is provided for heading and depth.

Tilt System
Tilt platform providing 90 of tilt from the horizontal. The camera platform is designed to accommodate most commercial TV cameras. The tilt is provided with positional feedback with the tilt angle is displayed on the video overlay.

Two separately controlled lighting channels. Each channel has two fused SEAEYE 150W lamp units. Lamp units can be moved individually to suit local operating conditions.
