Metocean consultancy

Our team of experts has a  profound knowledge of the regional ocean processes and have well-established methodologies for metocean data analysis for offshore operations and engineering.

Our capability is based on a broad range of project experience, coupled with a thorough understanding of the metocean data requirements and analysis techniques required for coastal and offshore developments.

Metocean data Analysis

Using data mining techniques on our long-term hindcast, statistics can be examined at monthly, seasonally or yearly scale within the entire model domain. Additionally, anomalies can also be quantified. 

Extracted site specific data can be used for time-series analysis techniques such as joint probability or extreme value analysis. These data can also be used for time-domain analysis for analytical techniques such as persistence and Sequenced Downtime Analysis (SDA). We have the expertise to provide the right kind of data analysis for your project.

Some of the standard analysis outputs we produce for waves, winds and currents are:

  • Metocean design criteria - return period values and extremes

  • Persistence exceedence and non-exceedence matrices

  • Joint probability distributions

  • Tidal analysis and predictions

  • Time domain and zero-down-crossing analyses

  • Spectral and frequency domain analyses

Optimisation of offshore operations

For downtime assessment / workability analyses of installation and maintenance operations we use analytical techniques including Sequenced Downtime Analysis and persistence analysis, giving information on expected job completion times and/or persistence non-exceedence chances (% of time good weather windows) based on the operational criteria (e.g. limiting wind and wave conditions).

Sequenced Downtime Analysis is a powerful analytical tool which uses our long-term hindcast data to examine operability and weather downtime on complex offshore projects.

Graphical and tabular outputs enable the user to understand project duration at differing levels of certainty, increase awareness of key milestones to minimize “knock on” slippage and compare annual and inter-annual results.

Analysis of operations

Analysing operations and evaluating processes allows companies to further optimise their future operations. Access to accurate metocean data is key to get a better grip on the effects of weather on operations / vessel performance.

Data APIs are provided which allow easy access to our metocean datasets. It allows clients to retrieve the historical nowcast / hindcast information for a specified location or along a ship track. The API will return the metocean conditions for the specified location or ship track for further in-house analysis.

When required we can also perform vessel performance and/or behaviour analyses.
