OFFSHORE APPLICATIONS
“The process of checking the location that a pipe or
cable first touches on the seabed during construction
operations.”
“The process of surveying a subsea pipeline to check
its location and condition.”
TOUCHDOWN
MONITORING
PIPELINE
SURVEY
The Ubiquitous OCTANS
OCTANS 3000 Gyroscope and motion sensor has been
used for touch down monitoring since its introduction
to the market in the late 90’s. OCTANS NANO now offers
the same reliability for half the volume and at affordable
cost. With the introduction of INS and USBL solutions
iXBlue now delivers even higher levels of performance.
Smooth Accurate Navigation
By fitting the ROV with a ROVINS or PHINS, all the
benefits of inertial navigation become available: a more
accurate and smoother ROV position translates to a
more accurate assessment of the final pipeline position.
And now, ROVINS NANO offers the same benefits as
survey-grade products but at a much more afforable
price for less demanding requirements.
From Shallow to Deep
GAPS USBL includes an Inertial Navigation System in
its acoustic head which allows it to be pre-calibrated
and extremely accurate.
• 200Hz position update
• 3X smoother than acoustic positioning
• post-processed quality in real time
The 3-D hydrophone head combined with robust signal
processing result in the widest antenna aperture
allowing the tracking of targets horizontally even in the
shallowest water.
The latest generation of GAPS is bringing compatibility
with third party beacons (WB1) to facilitate subsea work.
It is no longer required to deploy additional transponders
in an already existing field of operation. The system
can be deployed on any kind or size of vessel, including
barges and pipelay vessel, and a separate survey vessel
can often be eliminated from the operation.
The high power low frequency nature of POSIDONIA
means reliable positioning is available even at long
laybacks through the extremely difficult acoustic environment
of a pipe lay vessel.
As-Laid and Out of Straightness
Pipeline survey operations may be conducted for a
number of reasons. iXBlue sensors and solutions
are key success factors. As-laid surveys are used to
confirm the final location of the pipe, checking that:
• the pipe has been laid to the correct tolerance
• the pipe has not been damaged during lay
• there is a need for remedial work
• a baseline for later inspection surveys is provided
Positioning is vital to ensure the pipe has been laid in
the correct position, and for future baseline surveys.
Good ROV heading and attitude data is necessary for
these operations. OCTANS 3000 is the industry standard
gyro, and is perfect for these surveys.
Save time with INS
If real time data is required, ROVINS features the same
form factor as the ubiquitous OCTANS 3000 and allows
the ROV to be easily upgraded to full inertial capability.
The high update rate and smooth position obtained in
real time mean there is generally no need to post process
the positioning data prior to final chart production.
Extreme Accuracy
The move to deeper water and higher temperature
products combined with tighter pipeline design tolerances
has led to a greater need for out-of-straightness
surveys. Where the ultimate in accuracy is required,
iXBlue produces the PHINS 6000 INS, the ideal tool for
3D out of straightness surveys. The data acquired with
a ROVINS or PHINS 6000 in real time is suitable for
as-laid chart production.
DELPH INS is the iXBlue software tool for INS data
re-processing. It offers:
• a complete set of dedicated tools available for
navigation improvement and QA/QC analysis
• quick and easy integration in processing workflow
• an intuitive and user-friendly Man Machine Interface (MMI)
• cost effective and scalable solutions for all
applications.

OFFSHORE APPLICATIONS
“Cut to length operations are vital to the correct
positioning of pipeline lay down points.”
“Pipeline Crossings: Laying a pipe over the top
of an existing object, usually over some kind of
pre‐installed protection.”
CUT TO LENGTH
PIPELINE
CROSSINGS
If no ROV is available, an USBL beacon may be installed
on the pipe, as well, the seabed position of the transponder
may be used to calculate the remaining pipe length.
High performance in shallow water
iXBlue offers a number of systems for cut-to-length operations
in shallow water, GAPS is the ideal tool for these
operations thanks to its pre-calibrated characteristics
and simplicity of deployment, together with its
excellent horizontal tracking performance. It does not
exclude a robust performance in deep water (> 4000m
depth).
Extreme range in deep water
In deeper water, the POSIDONIA is capable of performing
cut-to-length operations directly from the pipelay
vessel, with no need for a separate survey vessel.
Ultimate accuracy
For ultimate accuracy, iXBlue offers the RAMSES synthetic
acoustic positioning system.
With a beacon placed on the lay down point and another
one attached to the pipe, as soon as the beacon on the
pipe reaches the seabed, the ROV is able to perform a
metrology operation between the two beacons measuring
the remaining length down to a few centimeters.
Compatibility
The latest generations of RAMSES and GAPS are
bringing compatibility with third party beacons (WB1) to
facilitate subsea work. It is no longer required to deploy
additional transponders in an already existing field of
operation.
A new approach with RAMSES, for higher productivity
When it comes to pipeline crossings, accuracy is
vital. In order to minimize risk it is necessary to
navigate relative to the pre-laid mattress. RAMSES is
the latest building block in the iXBlue range of subsea
positioning systems. Along with features such as
sparse array and automatic calibration of beacons
(SLAM*), RAMSES introduces relative navigation at
LBL accuracies, giving even more performance and
a high-update rate with ROVINS NANO.
*Simultaneous Localization and Mapping
No lengthy calibration of the subsea beacons is
required. The RAMSES in combination with INS SLAM,
automatically calibrates the positions of the beacons
as the ROV deploys them and moves back to its
monitoring position. Within a very short time, the INS
(ROVINS NANO, ROVINS, PHINS) switches to navigating
with the RAMSES aiding feature, resulting in position
accuracy relative to the crossing better than 10cm.
Compatibility
The latest generation of RAMSES is bringing compatibility
with third party beacons (WB1) to facilitate subsea
work. It is no longer required to deploy additional transponders
in an already existing field of operation.

OFFSHORE APPLICATIONS
“The process of positioning a mobile rig on a
pre‐selected location.”
“Placing structures on the seabed.”
RIG MOVE
STRUCTURE
PLACEMENT
Conventional Rig Move
For a conventional rig move, reliable lightweight
equipment is desirable. QUADRANS is iXBlue’s latest
fiber-optic gyrocompass aimed at IMO grade navigation
requirements.
Acoustic Rig Moves
Often rigs need to be positioned relative to existing
seabed structures, the precise position of which are
not known. Current techniques rely on installing LBL
positioning equipment on the legs of a jackup rig. This
dangerous procedure results in very accurate positioning
but is slow and often leads to the loss of the
equipment installed on the legs. Conventional USBL
equipment cannot be used on a rig due to the required
calibration which is impractical.
With its internal INS, GAPS is pre-calibrated and
therefore can be installed without the need for a separate
UBSL calibration. The GAPS can be installed on
a temporary over-the-side pole, or even installed on
the drill string. A single transponder is installed on the
subsea structure. The GAPS is configured to output the
relative position of the transponder.
Compatibility
The latest generation of GAPS is bringing compatibility
with third party beacons (WB1) to facilitate subsea
work. It is no longer required to deploy additional transponders
in an already existing field of operation.
All kinds of marine construction require the placement
of objects on the seabed at defined locations. iXBlue
solutions can be combined in many ways to achieve the
required positioning accuracy.
For instance, a simple mattress placement may be
achieved through the use of a GAPS USBL beacon on
each end of the deployment frame.
For ultimate accuracy, an INS on the structure
combined with RAMSES will give attitude, orientation
and position throughout the deployment.
Releasing the structure from its deployment rigging
can be achieved without ROV intervention through the
use of the iXBlue range of heavy duty acoustic releases.
iXBlue Solutions
GAPS: the pre-calibration and the excellent performance
in shallow water combined with horizontal tracking
capability, makes GAPS the ideal solution for deployment
from barges, even in extremely shallow water. The latest
generation of GAPS is now compatible with iXBlue
releasable transponders for limited load handling
(up to 5t) and with third party transponders if they are
already installed.
ROVINS and PHINS: when it comes to high accuracy,
INS will improve acoustic positioning and provide full
attitude of the structure during the deployment process.
POSIDONIA: the solution for deep/ultra deep water
positioning.
RAMSES: LBL grade accuracy without the usual disadvantage.
OCEANO: heavy duty acoustic releases to handle the
release of the heaviest loads with no external ROV or
diver intervention.
OCTANS NANO: heading and attitude data ideal for
structure monitoring.

METROLOGY
BEACH PULLS
Metrology operations are traditionally time consuming
and expensive to get right, involving the deployment of
many seabed acoustic beacons and a lengthy calibration
and data gathering procedure.
Traditional Method
when you want to perform a traditional metrology
operation, iXBlue is able to provide OCTANS for
measuring connector attitudes and headings.
COMMET, Acoustic Aided Inertial Method iXBlue’s
approach of Acoustic Aided Inertial Metrology uses a
Simultaneous Localization And Mapping (SLAM) technique.
Equipment inventory and time to complete are
drastically reduced with no compromise on accuracy.
• a ROV equipped with PHINS and RAMSES is used
in a two-stage process to measure:
1. the distance between two beacons installed
in the connectors
2. the heading and attitude of the connectors.
• using the SLAM technique means thousands of
acoustic measurements combined with the best
commercially available inertial measurements.
• metrologies no longer need to be line of sight in
order to be completed quickly.
• the SLAM approach can even conduct multiple
metrologies simultaneously, tying a number of
structures together in a single ROV dive.
• redundant processing using multiple techniques
leads to the most robust solution.
Beach pulls are particularly challenging environments
for acoustic positioning systems. The shallow water
makes for horizontal tracking and a high degree of
multi-path effects.
Challenging acoustic environment
The unique acoustic performance of the GAPS USBL,
with its 200 deg aperture and exceptional shallow water
performance, makes it the only choice for tracking
the pipe or cable right to the surf zone. The signal
processing within GAPS has been specifically designed
to minimize multi-path effects.
Best in class performance
As well as the best in class performance for shallow
water operations, the pre-calibrated nature of
the system is vital in these operations. GAPS can be
installed on a pipelay barge or cable lay vessel with no
further calibration required.
The attitude and heading sensor within the GAPS
system is an inertial navigation system (INS) that is
integral to the acoustic head.
GAPS is de facto the standard for shallow water
operations.
... up to 200°!

OFFSHORE APPLICATIONS
“The process of burying a subsea pipe or cable.”
“Automatic software control of ROV position,
heading and attitude.”
TRENCHING
ROV DP
OPERATIONS
Two distinct (or combined) problems have to be solved
when it comes to plough tracking:
• in shallow water the tracking system must be capable
of operating with a horizontal target (high elevation).
• in the case of a large plough, the power required to
tow the vehicle is immense and produces a high level
of noise as well as a great deal of disturbed water.
In some cases, acoustic signals between the plough
and towing vessel are blocked completely, meaning
an additional vessel is required to track the plough.
Remote USBL Deployment
iXBlue has two approaches to solve the problem of
tracking a trenching tool: either deploying GAPS
below the acoustic disturbance or behind the acoustic
disturbance.
Because GAPS includes an Inertial Navigation System
it does not need to be rigidly attached to a ship. By
deploying the GAPS below the towing vessel in quiet
undisturbed water, reliable tracking of the plough is
100m water depth
achieved. A second approach is to mount the GAPS on
a tail buoy and deploy it aft of the towing vessel. This
places the GAPS well away from any acoustic noise or
disturbed water. For the ultimate in positioning, the
plough may be equipped with an INS like the ROVINS.
OCTANS NANO is an economical choice providing basic
heading and attitude data impervious to magnetic fields
whilst being robust enough for the demanding environment.
It is now available with the INS benefits thanks to
the introduction of ROVINS NANO.
300m layback
Software and sensors detect the ROV position and
attitude to control the thrusters, automatically placing
the ROV at the desired location.
The best in positioning technology: survey-grade
For ultimate performance ROV DP needs position and
attitude data of high quality at a high data rate. ROVINS
is ideal, providing this data at up to 200 times per
second. By having the most accurate data at high speed,
the DP system can keep the ROV very stable, allowing
the pilot to concentrate on the job at hand.
For more day-to-day tasks requiring an enhanced DP
system, the ROVINS NANO is the most effective solution.
FEATURES:
• position attitude and heading stabilization
• auto speed and heading
• mid-water station keeping
• riser inspection
• point and click maneuvering
• pre-planned mission tracks
Whichever the product range, inertial velocity is always
available, even when DVL is not, as it will utilize acoustic
aiding like RAMSES.
ROVINS NANO and RAMSES is the best combination
possible to navigate within an LBL network (iXBlue
or third party) and are especially designed for Sparse
Array navigation.
With iXBlue inertial navigation systems and its latest
in-house algorithm ALIX, operations are seamless
thanks to automatic and autonomous aiding data
weighting which computes the highest quality navigation
solution.

OFFSHORE APPLICATIONS
“A computer-controlled system to automatically
maintain a vessel’s position and heading by using its
own propellers and thrusters.”
“Combining inertial and acoustic positioning
technologies: the best way for subsea positioning with
less beacons and no compromised performance.”
VESSEL DP
SPARSE ARRAY
NAVIGATION
Vessels operating in deep water need an alternative
to GPS for positioning. In shallow water Taught wire,
Fanbeam, or Radar systems are often used, but in deep
water and away from fixed structures. These systems
are not viable. Standard acoustic positioning systems
become too noisy for DP operations beyond around
1500m.
DP PHINS has been specifically designed as an add-on
to an existing acoustic DP system. By smoothing the
data from the existing USBL system, applying L/USBL
principals. DP operations can be conducted in much
deeper water than was previously possible, all without
major changes to the DP or acoustic systems on the
vessel.
POSIDONIA is iXBlue deep water acoustic system. When
coupled with a ROVINS or a PHINS, the inertially aided
L/USBL mode becomes available, bringing the possibility
of using acoustics for DP positioning, even in the
world’s deepest oceans.
For shallow water operations Taut wire can be a problem
as the range of movement is a function of the water
depth: the shallower the water, the less movement is
possible.
The excellent horizontal performance of GAPS
combined with the new L/USBL/INS mode allows world
class positioning using only one or two beacons in very
shallow water. New releasable iXBlue beacons can be
used (activated from GAPS itself) or third party already
existing beacons.
For shallow water pipe or cable lay operations, PHINS
DVL is a viable DP reference system. With a station
keeping performance of around 0.5m/hour or 0.1%
distance traveled, even the longest GPS outages can
be dealt with. By adding RAMSES with seabed beacons
widely spaced along a route (greater than 1km spacing)
better than 40cm positioning accuracy is achievable
along the whole route.
The tight coupling of acoustic systems with inertial
navigation systems offers new modes of operation for
underwater positioning. Sparse array navigation is one
of them. By fusing acoustic ranges to transponders with
the intimate knowledge of the vehicle motion provided
by the INS, it is possible to reach or exceed conventional
LBL performance. Navigation is now possible with
only one or two beacons, where previously many were
mandatory, including new releasable iXBlue beacons
or third party already existing ones.
PHINS and RAMSES are stand alone devices, but when
connected together with a single cable, they make a
complete sparse array navigation system without
requiring additional topside equipment.
LBL array installation and calibration procedure:
Typical subsea field developments can require more
than 100 seabed deployed transponders. The time taken
to deploy and calibrate such a large array represents
a significant cost. With the sparse array techniques
made possible by RAMSES, far fewer transponders are
required. Rather than requiring at least 4 transponders
in range to calculate a position, navigation is possible
with only one single beacon in range.
ROV robust positioning:
RAMSES + PHINS/DVL on the ROV only requires one or
two acoustic transponders in range in order to maintain
accuracy. A robust position solution is still available even
with ROV operating in shadow zones or within acoustically
challenging conditions.
Acoustic array propagation:
With the SLAM (Simultaneous Localization and
Mapping) algorithm running in RAMSES it is possible
to dynamically extend the acoustic array by adding
additional transponders. On the fly, RAMSES will use
the additional data to calibrate the position of the
new transponders before using them in the sparse
array solution.

IXBLUE APPLICATIONS
FIBER-OPTIC

ACOUSTIC
TECHNOLOGY
At the heart of an iXBlue INS lies a fiber-optic
gyroscope (FOG), an extremely high performance
rotation sensing device based on the Sagnac effect,
which is a relativistic effect discovered at the beginning
of the 20 th century.
A FOG uses optical waves propagating in a fiber-optic
coil to measure a rotational rate accurately. This
apparently simple design takes full advantage of the
reciprocity principle in the propagation of light, which
enables a perfect device to be created from imperfect
components.
iXBlue FOGs are the result of more than 30 years of
research and development, and they address the most
demanding navigation applications and performance
requirements from 0.1°/h to 0.001°/h. Thanks to
in-house mastery of all FOG’s key components
(optical fiber, coil winding, modulator and source)
in combination with advanced modeling of potential
environmental sensitivities, iXBlue FOGs are
insensitive to temperature changes and magnetic
perturbations, as well as resistant to extreme
shocks and vibrations.
As of the end of 2014, iXBlue has delivered more than
10,000 high-performance FOGs.
iXBlue has developed its own technology, from transducers
to power amplifiers, thanks to its expertise in
engineering and signal processing. iXBlue delivers the
full spectrum of underwater acoustic solutions, from
the very low to the very high frequency range, in order
to meet all the challenges of underwater operations:
• medium and long-range acoustic positioning systems
(GAPS)
• high-resolution acoustic imagery and mapping (FLS
product line)
• synthetic LBL positioning systems (RAMSES)
• acoustic transponders (OCEANO)
iXBlue products offer:
• subsea positioning
• acoustic tracking
• metrology and DP solutions
• sparse array operations
• pipeline survey
As a FOG is a completely passive device with no
mechanical dithering, sealed cavity or high-voltage
discharge, it has an unrivaled longevity and reliability
as well as very low power consumption.
