James Fisher Marine Services, part of James Fisher and Sons plc, is proud to announce that Vattenfall, one of Europe’s leading -wind park operators, has ordered a full Mermaid® system license for the strategic planning of its offshore wind farm operations. Read more >

Mermaid Release Notes v1.1.1.3

We are pleased to announce that the latest version of Mermaid is now available. In this release we’ve made a number of changes to improve the user experience, particularly when working with the map.

New Features and Functionality

MM-1869: Improvements to map side bar.

After adding support for Shapefiles in version 1.1.1.1 we decided to make a number of changes to how items on the map are added and edited. These changes should make it much easier to add and items and to edit them. Read more >

Mermaid Release Notes v1.1.1.2

The newest release of Mermaid is now live.  Over the past couple of weeks developed a new utility to assist our European users called Treylya. We’ve also performed a number of small bug fixes and usability improvements for Mermaid.

New Features and Functionality

MM-1502: Tool to convert ZIPS from UK-CSV to Euro-CSV.

Some of our European users wanted to access the contents of the raw ZIP files that the Mermaid simulator kicks out (details here). Unforunately because Mermaid works in UK/US CSV format, it’s not easy to open these CSVs in Excel when running in a European culture. Read more >

Mermaid Release Notes: v1.1.1.1

The latest release of Mermaid is now live. We are pleased to have added importing of ESRI Shapefiles to your map, and added further ways to analyse the progress of your operations. Please see below for details of the new features and fixes.

If you’re not already a Mermaid user, you can get a free two-week trial and see for yourself just how effectively Mermaid can control weather risk on your operations. We are holding online training webinars over the 27th and 28th of July, so do get in touch and we can add you to the course. Read more >

Mermaid Release Notes: v1.1.1.0

We’re thrilled to be announcing a new release of Mermaid with a whole slew of new features and improvements. You’ll find all the details below, but as there are so many improvements, we thought that we’d produce a couple of videos to show off the biggest ones – enjoy!

Remember that if you’re not already a Mermaid user, you can get a free two-week trial and see for yourself just how effectively Mermaid can control weather risk on your operations.

Vessel Utilisation – Part 5: The analysis of results outside Mermaid

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 take a look at the results we generated by running this script on our cases, considering only simulations starting in June.  We’ll also consider the process we have undertaken and the impact that this type of analysis can have on the success of a project. Read more >

Vessel Utilisation – Part 4: An overview of bespoke post processing

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) is a fairly good position, however, we think there might be opportunity to improve on this.  The issue we have is that our post-processing requirement is outside the type of charts and tables offered by Mermaid.  Read more >

Vessel Utilisation – Part 3: The analysis of results using Mermaid

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 generated and will consider the impact these can have on our decision making.  Finally, we’ll make some decisions regarding the next steps we should take.

Box Whisker Charts

In this post we are going to analyse our results using Mermaid’s “Duration Box Whisker Charts”, here’s a quick overview of the data represented by different elements of these. Read more >

Vessel Utilisation – Part 2: The simulation of cable lay operations

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 installation vessel?”

In addition we sketched out our operations, at quite a high level, ahead of putting them in to Mermaid, this sketch is shown below:

Overview Flow Diagram

In this post we are going to look at how we can model these operations in Mermaid and consider, in a little more detail, how we vary the length of the lay and trench operations. Read more >
