SeisWind® offers a seismic solution built upon three key components: acquisition, positioning and processing.
Innovative acquisition techniques and hardware include a tuned multilevel sparker source designed to meet the demands of penetration with the highest quality of resolution by providing a broadband spectrum at ultrafast repetition rates.
Our streamer cables are customised to offer single hydrophone per group to maximise frequency response, with group intervals available from 1 m spacing. Utilising state-of-the-art seismic recorders with the capability to sample up to 16 kHz, allows us to offer resolution of > 20 cm in the shallow section. Source and streamer tow depths are optimised for efficient weather tolerant acquisition.
Navigation and accurate timing are key to the SeisWind® offering where our solution is derived from an integrated system based on Fugro's proprietary differential global navigation satellite system Fugro Starfix and the Fugro RTKPod tailbuoy tracking system that utilise an innovative moving base algorithm. High frequency navigation data is cross corelated with the direct arrival from the seismic source to determine arrival time from source to receivers. The data feeds an augmented process that computes a complex least squares adjustment to guarantee a robust, reliable and accurate solution.
Quality control is paramount to seismic acquisition and ensures you have the highest quality data you need. Our experts deliver reports that are generated after each survey line to analyse the quality of both the seismic and the navigation data independently.
Access to high resolution seismic datasets is key to derisking your project. Our dedicated global seismic data processing team develops and integrates proprietary processing flows, tailored to extract maximum bandwidth and resolution from the acquired seismic data set. Innovative modules within the software are used by our experienced team to create accurate results.
Data acquisition services across the full bandwidth of geophysical sub-bottom imaging services, include:
- Shallow Sub Bottom Profiling
- Single Channel UUHR Seismic
- Multichannel 2D UUHR Seismic
- Multichannel 3D UUHR Seismic
Understanding near surface geology and derisking shallow hazards for offshore wind farms and offshore developments is critical. Innovative and integrated seismic offerings focus on near surface resolution, delivering superior sub-surface imaging in all geological settings.
Offshore Wind Farms: The development of offshore wind farms requires a detailed assessment and understanding of shallow geohazards such as shallow faults and buried channels.
Offshore Developments: Integrity and management of offshore infrastructure requires a complete understanding of the near-surface geology.
Boulder Detection: Identifying and derisking shallow hazards like boulders is key to a wide range of offshore activities, ranging from wind farm foundations to pipeline and cable route surveys, where coring, piling and dredging activities take place.
Shallow Gas Detection: Presence of shallow gas can pose heavy constraints and risks for all offshore foundation and engineering activities. Derisking through delineation of sub-surface hazardous is crucial.
Pipeline and Cable Route Surveys: Accurate understanding of very shallow sub-surface geology is critical to all successful pipeline and cable route surveys. Identification of shallow stratigraphy and potential geohazards can mitigate risks at a very early stage of projects.
