Positioning Services
Offshore positioning uses high-precision satellite-based technology to identify the exact location of vessels,
equipment and infrastructure.
A ‘precise position’ is the fundamental parameter for all survey and engineering operations at sea.
Such operations rely on a global infrastructure and expertise to deliver high accuracy positioning,
globally, at any point in time.
Fugro’s innovative positioning infrastructure and expert staff have ensured a quality-controlled and
cost-effective positioning service to the offshore industry for nearly 30 years. Based on Fugro
proprietary infrastructure, hardware and software.
Rig Move Services
Drilling rig operations and similar high-cost activities call for quick response times and minimal downtime.
That’s why Fugro’s extensive range of drill rig positioning services include specially
designed hardware, positioning systems, vessel spread and tug management systems,
GPS kinematic solutions and vertical seismic profiling (VSP) services. Together, these
support tow-outs, inter-field moves, alongside positioning, anchor drop control, positioning
confirmation and attitude monitoring.
Subsea Acoustic Positioning
If you’re looking for the most accurate subsea navigation and positioning system
available, look no further than Fugro.
Our long baseline (LBL), ultra short baseline (SBL) and combined techniques (LUSBL)
provide readily-configurable systems to suit your exact underwater positioning or
tracking requirements with guaranteed precision.
Additional support in the form of Starfix.Acoustics and Starfix. USBL software modules
provides enhanced integration, calibration and processing potential.
Dredging and Coastal Operations
Dredging activities, aggregate collection, coastal and harbour works - these are
ideal operations to benefit from Fugro’s Starfix DGPS system and portable receiver
packages.
Fugro assists in the correct positioning and monitoring of dredging vessels and equipment.
Infrastructure Positioning
All the major barge contractors have, at some stage over the last three decades,
depended on Fugro’s specialist skills to support their marine infrastructure
positioning operations.
From templates and jackets, deep-water moorings and suction piles to wellheads,
manifolds, pipelines and umbilicals, our specialised application software integrates
acoustic and visual sensors to provide real-time guidance and control information for
safe and efficient operations.
Fleet Management
Fugro’s diverse experience in fleet-tracking and positioning allows it to provide
turnkey solutions, tailored to the specific monitoring and tracking requirements
of marine vessels.
Fugro’s Vessel Tracking System provides visual tools - based on GIS and web
technologies - to analyse vessel movement and provide a comprehensive reporting
mechanism. The system is a unique blend of GIS, GPS, Communication and Reporting
technologies providing customers with continuous access to essential management
information.
Exploration Seismic Solutions
Our DGPS systems are used extensively by the offshore seismic industry to
locate source ‘guns’ and streamer tail buoys.
Fugro has developed a range of specialised positioning solutions to support seismic
surveys, including Starfix.OBC for ocean bottom cable and 4D seismic survey
operations. Our proven software suites comprise First Break Picking algorithms plus
telemetry and control systems, helping to provide comprehensive, cost-effective
solutions in support of multi-vessel OBC spreads during laying and positioning of
subsea cables.
Inertial Navigation System (INS)
Fugro has pioneered the development of INS (Inertial Navigation System)
solutions to address subsea positioning for deep and ultra deep-water oil
and gas projects.
This innovative technology enables Fugro to combine the latest advances in
Inertial Navigation with proven sensors, offering a time saving subsea positioning
tool to suit the demands of the drilling and construction markets.
Fugro Starfix Software
All Fugro positioning and construction services are brought together in the 4Starfix integrated survey and positioning
software, which supports the widest possible scope of positioning and survey activities.
Dedicated modules in the software cover rig move operations, barge operations,
marine survey data collection, underwater positioning and much more.
Differential Positioning Systems
Fugro’s state-of-the-art differential GNSS augmentation systems were
developed specifically to meet the offshore community’s demand for robust
and accurate positioning solutions worldwide.
Using differential GNSS algorithms, Fugro removes any errors from data
monitored from over a hundred Fugro land-based monitoring stations. A double
redundant network of L band communication satellites delivers the correction data
in real-time to vessels and other mobile users the world over.
Fugro positioning systems are delivered to an ever increasing client base
comprising:
- Offshore oil and gas companies
- Offshore renewable energy companies
- Offshore contractors
- Offshore drill rig operators
- Survey and research vessels
- Cruise vessels
- Offshore cable installation companies
Advanced Solutions
Fugro positioning systems are completely scalable to meet a broad range of
requirements from robust L1 differential GPS to fully redundant dual frequency,
orbit and clock correction of multiple navigation satellites constellations.
Fugro Offshore Positioning Services are based on the Starfix range of positioning
systems which includes:
- Starfix.G2 - the Fugro flagship, dual frequency orbit and clock positioning system seamlessly incorporates GPS and GLONASS satellites with 10 cm accuracy worldwide
- Starfix.HP - a dual frequency, multi reference station carrier phase computation with less than 10 cm accuracy worldwide
- Starfix.XP - a dual frequency, orbit and clock computation, based on NASA/JPL reference stations with less than 15 cm accuracy
- Starfix.L1 - the single frequency differential GPS service provides worldwide differential accuracy and coverage
All Fugro dual frequency systems are designed to mitigate problems of increased
ionospheric activity worldwide that have an adverse effect on the satellite signals
used to derive a positioning solution.
Fugro’s augmented infrastructure is designed to provide the highest level of
redundancy for the most demanding safety critical operations. Differential GNSS
solutions are based on at least three fully independent positioning calculations,
three separate groups of independent reference stations, two independent network
control centres and various hardware platforms. All services are broadcast by at
least two different communication satellites anywhere on earth.
