About Talaria.

Talaria is a smart data and sensor technology company focused on providing services to clients whose engineers require an understanding of seabed properties. Ultimately what Talaria offers is the highest integrity 3D anisotropic model data, at scale and at the lowest cost in the market.

We support companies which are designing, installing and operating offshore infrastructure, such as wind farm and other foundations, cables for electricity and telecommunications, and subsea storage sites for carbon dioxide. We offer advanced, cost effective, geophysical sensing of the seabed enhanced by our proprietary technology. The aim is to deliver a paradigm shift in seabed and subsurface ground models for engineers to use in designing infrastructure emplacement following the current design model workflows, such as PISA, and the next generation of workflow models such as PICASO. We aim to do this principally by using geophysical methods to determine, among other properties:

• shear modulus
• bulk modulus
• porosity & permeability
• pore pressure and intra-layer pressure differentials
• layer integrity via conglomerate/gravel/boulder analysis
• thermal capacity (conductive and convective)

Although it is clear that this can preclude some of the need for certain data acquired by seismic CPT, these detailed datasets of course do not replace the principal q_c profiles delivered by CPT and extensive laboratory sample testing demanded by PISA and PICASO workflows. What they do though is give accurate inital physical paramaters at high resolution and scale accross the wind farm site. This enables the engineer to:

• deal much better with the variability in the design outputs and give a higher confidence to the final engineering design.
• make finite element modelling runs more applicable and menaingful to a larger area and enable faster and better model initialisation.
  

These datasets can produce models which are a signficiant uplift on any geophsycially derived models to date since:

• the models are in true 3D (not just interpolated 2D).
• the models offer true anisotropy measurements (yes, including shear modulus).
• the models are offered at scale (not just on localised sites already defined).
• the models are at a resolution needed for the client.
• the cost per square km can be an order of magnitude better than current datasets.

How can we offer these advantages?

Among other technologies, Talaria has developed a new semi-autonomous seabed tool which is compact, quick to deploy and recover without umbilical or ROV and cost-effective to use requiring no specialist vessel or handling equipment. It is the first time that accurate anisotropic seabed geophysical data can be collected on a scale and at a cost-base which is accommodated within the tightest of budgets alongside the core geotechncial input requirements.

Taking the best and making it better.

Other technologies you may be more familiar with such as 3DUHR (or UUHR) streamer seismic data is also used in the production of the large scale models. We have all seen great imaging from these datasets but trying to acquire 1m bin data at a pass larger than 25m wide has proved difficult to date. The subsequent cost due simply to the time taken to acquire the data makes this technique not viable at scale. However Talaria has new streamer implementations with wide-tow systems but with unique geometries which require modest towing hardware and can be used from the smallest PSVs. The new configurations are designed to be used with holographic imaging techniques which naturally support compressive sensing and allows much better spatial sampling than regular reflection seismic geometries and methodologies would allow using the same equipment. The key thing here is the integrated nature of the optimised acquisition configuration, towing methdology with the imaging technique.

Ultimately what Talaria offers is the highest integrity 3D anisotropic model data, providing superior and the most cost effective inputs at scale to your engineering design workflow.
