Solutions

Site Characterisation

Eliminating uncertainty about offshore subsea site conditions, we help our clients mitigate risk and ensure the long-term performance of their assets. Our technical studies and surveys deliver insights that provide a thorough understanding of offshore wind development areas and cable routes, guiding layout and design. Through state-of-the-art data collection and in-house analysis, we enable informed decisions and the de-risking of complex projects. Furthermore, our comprehensive range of solutions also support the conservation of the marine environment and the sustainable development of large marine assets.

  • Hydrographic survey (MBES, SSS)
  • Geophysical (SBI, SBP, Sparker, Mag)
  • Marine archaeology
  • Benthic and marine
  • Shallow geotechnics
  • Shallow geotechnics
  • Dimensional control
  • Magnetic anomaly
  • ALARP extensions (JUP support for nacelle/blade replacement, pUXO survey to extend JUP footprint at WTG locations)

Construction Support

Utilising our exceptional subsea positioning and monitoring tools, our  team are experienced in providing light construction support across offshore wind developments, including cable-lay support, touchdown monitoring, and cable burial assessments.

Delivering superior data quality and efficient construction data management, in addition to project management  and  communication with stakeholders both offshore and onshore, we provide unrivalled insights and improve outcomes in a safe, efficient and schedule-driven setting.

  • Monopile/jacket/anchor foundation installation support
  • Infield vessel-based support solutions (dropped object recovery, anode cage hook-up, pre-grout pile cleaning and inspection, mattress placement, scour survey)
  • Cable lay support (pre-lay and post-lay survey)
  • Touch down monitoring, pull-in monitoring, winch wire hook up

UXO Identification & Disposal

Unexploded ordnance (UXO) continue to pose a real risk to site developers, contractors and asset owners, even after decades of inactivity.

We are experienced in identifying, investigating and mitigating hazards with precision and expediency.

Fusing our expertise together with the SubSLAM X2 intelligent data collection system and sub-bottom imaging technology, we can accurately detect ferrous and non-ferrous items of UXO both above and below the seabed, generating full 3D models of UXO and other artifacts of historical importance in situ and in real-time.

In doing so, we substantially reduce the amount of vessel time required to investigate false positives, delivering considerable cost savings and a significant reduction in emissions.

Additionally, we provide the expertise and assets to precisely identify and remove boulders and other obstructions from the seabed safely and efficiently.

Subsea Asset Integrity

Marine growth on offshore wind structures can have adverse  consequences for the integrity, hydrodynamic efficiency, and longevity of assets, and may also encourage the establishment and growth of non-native or invasive species. Components that are exposed to marine growth may be subject to additional weight and stress, leading to damage and potential risks to watertightness.

Harnessing the power of SubSLAM X2, detailed information about marine growth on a structure can be delivered in real-time, as well as providing highly accurate year-on-year comparisons to monitor the rate and volume of accumulation. By accurately monitoring marine growth over time, asset owners can ensure that it does not exceed operational limits, as well as identifying when preventative maintenance is necessary.

  • Difference modelling to precisely identify areas where marine growth intervention and removal is required
  • Year-on-year comparisons provide an accurate understanding of marine growth accumulation, enabling cost and risk reduction for both existing and future projects in similar regions

Cable Route Survey &
Depth of Burial

Precise and accurate depth of burial information is essential for cable security and for reducing cable maintenance costs.

We provide efficient cable depth of burial surveys, together with accurate plotting of route position logs, through the combined use of our positioning survey solutions. Our team is experienced in deploying an extensive suite of leading-edge tools, including acoustic sub-bottom imaging technology, and integrated cable and pipe tracking systems.

  • Accurate and repeatable depth of burial data that identifies where remedial engineering is required
  • Precise location and size estimates of boulders and other objects adjacent to cables
  • Assess level of scour protection
  • Identify any areas of exposure or freespan
  • Assess the surrounding seabed to track changes to the environment
  • Surveys can be performed on energized cables, using acoustic technology

CPS Integrity Studies & Remediation

  • Pre-lay and post-lay surveys
  • J-tube entry (internal and external)
  • Cable Protection Systems (external)
  • Cable Protection Systems (into burial)

  • Vessel-based survey solutions for initial site assessment and contact identification
  • High definition 3D reconstructions of contacts in real-time, providing highly accurate measurable site plans for initial assessment
  • Experienced  in handling and recovering artifacts of historical importance to shore for safe storage

Marine Archeology

Offshore wind farm developments can occupy a significant area in the oceans, and turbine foundations pose the risk of impacting archaeology. We recognize the importance of subsea archeology; there are far fewer sites in comparison to land, and these may contain artefacts of historical significance that are not found elsewhere.

We understand how critical it is to ensure that archeological methods are efficient and executed with precision and care, to protect these valuable assets for future generations.

  • Vessel-based survey solutions for initial site assessment and contact identification
  • High definition 3D reconstructions of contacts in real-time, providing highly accurate measurable site plans for initial assessment
  • Experienced  in handling and recovering artifacts of historical importance to shore for safe storage

Digitalising offshore survey and inspection

We apply machine learning and artificial intelligence technologies to improve the efficiency of subsea surveys and asset management. The SubSLAM® X2 System forms the basis of a suite of powerful tools that can extract more information from atypical subsea inspection. Through the automatic detection of key features or anomalies, the Vaarst Machine Learning Platform provides Engineers and O&M teams with a more focused approach to asset monitoring and reporting. By leveraging ever more powerful artificial intelligence, personnel can spend more time on critical analysis and management, rather than watching hours of video.

Benefits

  • Better strategy for managing subsea assets• Increases
  • Increases speed of data collection and analysis
  • Reduced human intervention and person-hours
  • Improved safety offshore
  • Inspect more rapidly, less time offshore
  • Repeatable and reliable quantitative reporting

Reducing human effort in data analysis

Machine learning and artificial intelligence technology automate high-cost, error-prone tasks such as detecting defects or monitoring changes in corrosion. By removing the human element, potential inconsistencies can be avoided, and true values of certainty applied to measurements. Repeatable and reliable measures can be obtained to provide owners and operators much higher confidence in their asset condition report.
