 Press Releases

  • Partrac GeoMarine’s Dr. Kevin Black, Technical Director, and Dr. Patrick Friend, Business Development (Americas), would like to meet with you at the Scottish Pavilion (Booth 1161) during OTC 2019 in Houston. Partrac GeoMarine is a marine and coastal geoscience company with a global reach and reputation in seabed scour risk assessment and modeling, sediment transport studies, model verification, sediment mobility analysis, and metocean data collection and analysis. Our core skills combine oceanographic, environmental and geoscience/geophysical survey expertize. We work on solutions to problems involving sediment interactions with seabed assets and foundations, pipelines and cables, and free spanning issues. Our key sectors include offshore energy (oil, gas, LNG, Offshore Wind) and decommissioning. Through promoting a number of innovative technologies such as benthic flumes (devices to measure in situ sediment stability) and granular tracers (to quantitatively assess the movement of ocean sediments), the company has gained a strong reputation for quality, consistency and delivery. Our clients include ENI, EQUINOR, REPSOL, EDF, BOSKALIS, VATTENFALL, U.S. NAVY, USGS, US Army Corps of Engineers. Come and talk to us on Booth 1161 about your seabed-sediment interactions/metocean data requirements - or email Dr. Patrick Friend at pfriend@partrac.com

    An In Situ Flume for Seabed Sediment Transport Assessments

    Sediment transport occurs at the seabed due to frictional drag created by tidal- and wave-induced currents. It plays a vital role in many aspects of coastal, estuarine and offshore engineering. Sediment mobilization and sediment transport influence the necessity to dredge in harbors, ports and waterways, scour around offshore structures and buried pipelines and cables, and many other near-and offshore situations. Sediment transport can also give rise to significant nutrient exchange at the seabed, as well as resuspension of seabed contamination. Accurate, site-specific knowledge of sediment transport is essential to understanding these issues and reducing associated risks.

    The Voyager II Benthic Annular Flume is a novel, commercially available marine instrument designed to collect data on specific sediment transport parameters. It is deployed onto the seabed, cast off, and left to collect data (typically 1-2 hours). Water is recirculated over exposed bottom sediments and sensors monitor sediment erosion (and deposition). A reversible drive train can impose oscillatory stress onto the sediments. An on board water sampler can automatically collect samples of the flume waters. A submarine video records a vertical photographic profile of the upper 0.05 m (akin to SPI technology) and the erosion process. A sediment core (0.5 m) can be collected concurrent with deployment.

    Maximum shear stresses up to ~3 Pa can be imposed on bottom sediments. Depth rated to 200 m.

  • Metocean Services to Offshore Energy sector
    Partrac provides a full range of Metocean data services to the Offshore Energy Oil and Gas and Renewables sector. Here we show a Waverider Datawell Mk 3 buoy being deployed at Statoil's Hywind floating wind farm, UK....

  • Partrac is experienced in the Offshore Oil and Gas/ Renewables sector, with the provision of metocean and seabed data and surveys for new wellhead sites, proposed pipeline routes, LNG developments, offshore wind farms, and decommissioning operations in the UK and worldwide.

    The offshore wind industry in the US is poised to make a growing contribution to US energy markets, with continued growth expected in the coming years. Partrac has a strong track record in offshore renewables gained from over a decade of experience in more than 26 offshore wind installations in the UK and European North Sea. We support clients throughout the development and life cycle of their projects from oceanographic surveys, licensing, environmental baseline surveys through to geo-technical investigations, operation real-time metocean data collection and post-installation monitoring.

    Partrac shares the health, safety and welfare ethos of the Energy industry, and works to clients’ policies and management systems.

    Partrac can provide the following services to the Offshore Oil, Gas and Renewables industry in US coastal and continental shelf waters:

    • Metocean services
    • Baseline environmental survey
    • Benthic survey
    • Sediment mobility & scour risk assessment (including freespanning issues)
    • Cable and pipeline route surveys
  • Seabed Processes and Scour
    Partrac has extensive experience in seabed processes related to sediment transport and scour. Here we show a scanning sonar of the type used to monitor scour around jack up legs, foundations and in free-spanning studies....

  • Scour Monitoring for Jackup Operations, Teesside Offshore Wind Farm (EDF)

    Geotechnical investigations form a central element of site investigations for offshore developments, including offshore windfarms. Jack-up barges, which stand on legs penetrating the seabed to conduct operations, are commonly used at shallow (< 40 m) sites. However, in these shallow zones where the seabed is predominantly sandy, the legs are at risk from scour due to either current action or waves, or a combination of both. At the Teesside Offshore Windfarm scour was identified as a risk and Partrac were commissioned to provide a system for monitoring scour in real-time. We deployed a scanning sonar system, strapped to one of the legs and connected via a cable to power and a surface computer, to monitor the evolution of scour in real-time and in high resolution beneath the rig and around multiple legs. The system provided a useful tool for monitoring scour, and the influence of short term, but energetic squalls could be seen in the data.

    Pipeline Free Span Vulnerability Assessment (ENI)

    Free-spanning can develop in both cables and pipelines where the surrounding sediment matrix has been removed by scour processes. Where this becomes excessive then the free-span can exceed the design parameters, and the situation can become critical. ENI (UK) contacted Partrac when a buried fuel pipeline, which brings gas ashore at Point of Ayr on the northeast Wales coastline, developed an excessive free-span due to scouring. Partrac were charged with conducting a high level study to assess how the situation had developed, what type of immediate mitigation may de-risk the situation and whether the situation was likely to get worse in the foreseeable future. We collated site specific oceanographic, geological, geotechnical and bathymetric datasets, and undertook analysis of some collected sediment samples, to inform these areas. This project is ongoing and we continue to develop our analysis and advise the Client on the collection of new datasets which would be of use.
