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
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
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.
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.
|Maximum working depth
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
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.
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.
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:
Separately housed electronic unit. Accuracy ± 0.1% of full
Automatic pilot is provided for heading and depth.
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.
|Viewed from ahead
||Viewed from the stern
Two simultaneous TV channels are provided for simultaneous
viewing and recording from two video cameras. Video transmission
to the surface is via a dual balanced line driver and two
screened twisted pairs.
Surface Control Unit
This unit contains all of the surface vehicle control electronics
and surface outlets for ancillary equipment. This unit is
19" rack mountable. It is supplied in a transport case.
|Hand Controller and Surface Control Unit
A small remote hand control unit provides all of
the vehicle controls. The unit is supplied with a 5 metre
Surface Power Supply Unit
This unit supplies all of the power requirements for the vehicle
system. Line Insulation Monitors (LIM) are fitted to the AC
& DC power components for system safety and monitoring
purposes. The system power requirements are a 3 phase AC input
of between 380vac and 480vac at 15kva.
