T-VOS – is the first AI-based multi-objective voyage optimisation software for the shipping industry, capable of simultaneously optimising for time, fuels, TCE and emissions.

Combining Theyr’s high fidelity metocean data with a decade of academic research and development from the AI team at the University of Southampton and the Alan Turing Institute.

Rapid Data Access Service

Significantly reduce data transfer and handling requirements while increasing access to high-fidelity metocean forecast and hindcast global data sets.

  • RDAS provides the exact metocean parameter value for each specified location
  • Delivering ~1000 data points per millisecond.
  • Each data point provides multiple metocean parameters for historical or forecast route analysis.
  • Performs spatial and temporal bicubic interpolation between forecast grid points.
  • Ensures highly accurate route analysis.
  • Simple web-API access with comprehensive documentation.


An extensive operational metocean data portfolio ensuring maritime sectors access the most accurate information available. Theyr data processing, developed by our scientists, adds value and ensures unrivalled accuracy. Get the data you need, when you need it.

Theyr’s industry-leading RDAS data platform is built to manage high-fidelity, large scale, complex meteorological and oceanographic data-sets. Significantly reduce data transfer and data handling requirements while increasing access to the highest fidelity operational metocean forecast and hindcast global data-sets.


metocean Web Mapping Service – is a relatively simple and very efficient web-API/Web Mapping Service (WMS) producing on-the-fly map overlays for the exact area you require for each request. Producing an effective animation rate with lots of functionality and forecast parameters.

This is an extensively applied solution for our marine navigation app and fleet solution partners due to the simple integration and the highly visual and customisable nature of the API.


A comprehensive and fully customisable fifth-generation development suite for third-party navigation software and hardware applications that require GRIB data overlays.

Our GRIB-SDK efficiently requests, displays and analyses.

Modular design provides flexible integration choices.

SDK kernel for third party application integration.
