Time series variability blog

How do different aspects of the input metocean data affect Mermaid results?

There are a range of sources of variability when it comes to putting together a Mermaid analysis, and they can all affect the output statistics to various degrees.  It could be subtle changes such as weather thresholds, task durations or the level of suspendability; or more strategic changes such as vessel and port choice.  But that’s what Mermaid is designed for, for you to be able to tweak and optimise your operation to minimise the weather risk.

Comparison of using Mermaid metocean data against a higher quality dataset

With the recent addition of access to a 10-year hindcast dataset within Mermaid we thought it would be a good idea to provide some handy guidance and advice on how it should be used.

The general aim of this dataset is to allow users to generate some ‘headline’ average duration statistics that will be useful for things such as writing or reviewing bids and operation overviews.

The key things to be aware of with this dataset are threefold:

  1. The duration of the dataset is ten years (January 2006 to December 2015)
  2. The time step of the wind data is three hours whereas it is six hours for the wave data
  3. The horizontal grid resolution is 0.25°, i.e.
