Metocean Statistics by Artelia - StArt

Metocean Analysis, anywhere in the Pacific ocean, including cyclonic activity

  • Quick

    StArt is a fully online service: we provide analysis at your request, in a matter of minutes.

  • Using simulations tailored for cyclonic events

    StArt performs corrections on its metocean models, making them specially fit for cyclonics events.

  • State of the art cyclonic extreme analysis

    StArt provides accurate extreme values analysis of wind and wave conditions, even over areas highly impacted by cyclones.

What is StArt?

StArt provides through an online platform an easy access to Metocean Conditions gathering several statistics bespoke for companies harvesting Natural ressources & Energy from the Pacific Ocean.

StArt achieves accurate extreme analyses of wind and wave conditions even in locations subject to frequent cyclones/typhoons. This makes it a perfect fit for environmental impact assessment of deep-sea mining (oil and gas) operations, offshore wind farm development.

StArt combines numerical simulations and ocean observations (mostly from the Copernicus Marine Service) using a complex set of procedures to benefit from high-spec features of both specialties: the huge spatial (and temporal) coverage of numerical simulations and the high accuracy of mesurements.

How does it work?

The StArt service works in 3 major steps:

StArt gathers both metocean model datasets and satellite measurements.
StArt inputs cyclonic observations in its specific models
StArt then execute a full featured statistical analysis of the metocean condition around the location you requested.
  • 1
    For its analysis, StArt relies on severals Copernicus data, such as:
  • 2
    StArt merges hurricanes wind fields -from the NOAA's international Best Track Archive For Climate Stewardship (IBTrACS) database- in its atmospheric forcing using the Holland's model, before running a tailored wave propagation model (Wave Watch III).
    Thanks to this process, StArt is able to precisely represent the metocean condition in the Pacific ocean (for the moment only two pilot sites in Japan and New Caledonia).
    In order to provide the best possible accuracy, StArt compares those simulations with satellite observation datasets, such as:
  • 3
    Finally, StArt realizes handy representations of the corrected datasets (10 years of wind, atmospheric pressure and wave) including:
    • Time series
    • Monthy and annual mean/maximum/minimum of the main metocean parameters
    • Roses
    • Joint probabilty distribution
    • Occurences frequency of parameters
    • Exceedances frequency of parameters
    • Correlograms
    • Non-cyclonic extreme value analyse (wind speed and wave height)
    • Cyclonic extreme value analyse (wind speed and wave height)

Access the service

StArt is available upon request at

StArt is generated using E.U. Copernicus Marine Service Information

The service is accessible at any time, by personal and confidential registration, and provide free of charge until the end of the required maintenance period fixed at the end of March 2021, after which its financial conditions may evolve.

The use of the Service for the study of conditions in other areas of the World than the ocean Pacific – Japan and New Caledonia coasts - will be charged as per quotations, delivered upon request by the Service Provider to the Client.

Key features:
