  • Partrac's consultants provide data-led insights into the seabed and quantify the risks associated with mobile sediments and metocean processes during marine installation and operations.

    The last 12 months have seen the evolution and growth of Partrac’s geo consulting services, led by their Technical Director, Dr Kevin Black, and their team of modellers, geoscientists and oceanographers.

    Combining expertise in marine GIS, data mining and literature review, coastal processes / EIA, and numerical and CFD modelling, the company has  delivered successfully on a range of local and national projects in the coastal and offshore marine environment. Partrac’s expertise has enabled clients to de-risk the potential for scour during landfall cable installation activities, to meet marine warranty expectations, to optimise and plan more effectively for offshore cable burial, and to address impacts on sensitive seabed areas of construction phase operations.

    Currently the group is working with various agencies on a large scale project in Europe to improve the understanding of the dynamics of coastal mega sediment nourishments.

    Partrac’s consultants provide data-led insights into the seabed and quantify the risks associated with mobile sediments and metocean processes during marine installation and operations.

    Please call (+1) 713-730-3024 or email Dr Patrick Friend (pfriend@partrac.com) in our Houston offices to discuss your project.

  • Leading marine survey company Partrac recently provided key sea bed erosion data to the Scottish Association for Marine Science (SAMS), for a project funded by the Scottish Government since 2013, aimed at upgrading a fish waste dispersion model (NEWDEPOMOD) used by the Regulator to underpin the consenting process for the domestic aquaculture industry. The NEWDEPOMOD model will contribute to the industry’s growth strategy for aquaculture in Scotland to 2030, an ambitious, industry-led plan for sustainable growth across the entire aquaculture value chain.

    Partrac worked in conjunction with scientists from SAMS, Oban, and led a series of offshore data collection programmes at 11 commercial marine aquaculture sites off the Scottish west coast. The work involved the use of benthic flume technology to measure seabed erosion parameters, which the model needs in order to compute waste erosion, settling and dispersion. Benthic flumes are devices that are deployed to rest on the seabed and can be used to apply a controlled flow stress onto the surface of submerged sediments, and thereby determine the stability directly. Two flumes of the Voyager series were deployed at fish farm sites collecting data on seabed erosion parameters at organically impacted locations.

    Dr Kevin Black, Technical Director at Partrac said, “All models require input data to work properly, and it is key that data inputs from the real world are used in the model where possible so that they are as accurate as we can make them. The deployments of the flumes, in waters up to 40 m depth, has never been undertaken before at fish farm sites and the new data collected will now help us to improve the seabed erosion module within the NEWDEPOMOD model. Seabed erosion parameters for materials such as fish waste need to be measured as they cannot be derived any other way; this project, in particular, serves to illustrate our commitment to bringing innovation and technology to develop solutions for Clients”.

    Aquaculture is an industry of growing importance in Scotland supporting around 8000 jobs and worth an estimated £650 million to the economy. Scotland’s National Marine Plan (NMP) sets out a national strategy to increase Marine finfish production (whole wet salmon, rainbow trout, halibut, brown/sea trout) from 179,755 tonnes (2015) to 210,000 tonnes, by 2020, while taking into account environmental protection.  The Scottish Government consider that upgrading the DEPOMOD model will help developers and Regulators better understand the impact of fish farms on the sea bed, particularly as they develop further in higher energy locations – and the data provided by Partac is integral to the new model.

    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 mobilisation and transport influences dredge necessity in harbours and ports, scour around offshore structures, seasonal beach development and many other applications. 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 at rest 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.

  • 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 my 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.
