Introduction In the last part we looked at how we can use Mermaid outputs to perform a bespoke analysis and discussed the process of writing a script to extract additional information.  This example is reasonably simple, but the timestep by timestep nature of the results allows substantial detail to be considered. In this post we’ll[…]

Introduction So far in this series we have prepared and run a number of simulations and considered the results in Mermaid, all with the aim of answering the question: “When should we take the trenching vessel on hire, relative to the installation vessel?” We saw in the last post that our base case offset (32 days)[…]

Introduction Last time we finished the setup of the analysis by preparing the flow diagram.  We considered a number of options for modelling these tasks, ultimately selecting a clean, simple and easy to maintain approach.  We also performed a number of simulations. In this post we will take a look at the results we have[…]

Introduction Last time we outlined the analysis of cable installation operations for a hypothetical operation at WaveHub.  We looked at the map and the shelter characteristics of the vessels we intend to use and outlined the main objective of the analysis, which is: “When should we take the trenching vessel on hire, relative to the[…]

Introduction Marine operations often require multiple vessels which are assigned specific tasks to perform.  Often the tasks performed by the vessels are independent of each other (i.e. the vessels work alone) but are linked in such a way that one vessel is dependent on the other completing work.  In this series of posts we are[…]
