| Remote Positioning & Monitoring Services |
|
Fugro offers a range of cost-efficient remote services based on FANS® technology, for remote connection to offshore systems from an office.
The Fugro Remote Monitoring system monitors the movement of floating assets, such as FPSOs, FSOs and TLPs, remotely. Using decimeter accuracy, it can show the actual position at a point in time or movement over a period of time. For nearshore and offshore navigation, the Fugro Stand Alone Navigation solution requires no onboard survey crew, ideally suited for navigation support on jack-up work barges and rigs, tug boats and support and construction vessels.

Infrastructure Positioning & Monitoring
|
|
|
|
|
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.
Fugro has developed a monitoring system for long-term real-time monitoring of the dynamic behaviour of offshore structures related to oil and gas extraction from existing and future reservoirs. Precise GPS data gathering augmented with inter-platform precision levelling, sea level measurement and field wide geophysical data provides vital information on how to best mitigate and undertake remedial action. The results of the subsidence monitoring also aids local offshore structure design development.

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.
Seabed scans can be a useful source of information for Pre and Post Site Investigations and can be acquired relatively quickly from a vessel or a rig.
- Anchor Placement
- Site Clearances
- Debris Removal
- Artificial Reefing
- Structure Installation
