Mermaid Release Notes v1.3.0.7

We’ve made a number of small improvements to Mermaid, check them out below and if you’re interested in Mermaid please get in touch.

  • Gantt chart scheduler now uses the vessel port departure instead of the vessel site departure duration when the vessel leaves port.
  • Metocean time series chart will clearly indicate the AM/PM when you hover over it with your mouse pointer.
  • Undoing task operation happens correctly and the group inheritance button remains available in the flow diagram.
  • Results vessel summary table has been corrected to include missed transits.

Mermaid Release Notes v1.3.0.5

We’ve taken customer feedback on board and have made some exciting updates to Mermaid! Check them out below and if you’re interested in Mermaid please get in touch.

New Features

User-defined Percentile (P-values) in the results summary table.

Whilst Mermaid reports multiple default P-values in the results summary tables, users suggested they would find it beneficial to report bespoke values. As a result, we have added an optional column to the summary table where the user can set any statistically valid P-value they like. Read more >

Mermaid Release Notes v1.3.0.4

The latest release of Mermaid is now available.  We’ve added some new features, most of which have been requested by our users. If you’re interested in Mermaid please get in touch.

New Features

MM-2346: Unit Conversion

We’ve made changes to allow speed units to be shown in metre per second (default) or knots and for duration units to be shown in hours (default) or days.  Use the settings cog in the top right corner to set your preference.

MM-2342: Increase maximum task duration

The allowable maximum task duration has been increased from 170 hours (approximately 1 week) to 8760 hours (1 year). Read more >

Floating Wind Installation Sensitivity Study


This article presents a high-level study that uses Mermaid to look at the impact of metocean conditions on installing an array of floating wind turbines at three different sites in European waters.  The aim is to demonstrate both how useful and powerful Mermaid is and to inform the reader of how sensitive to wave height the tow and installation phase can be and how this varies significantly both seasonally and geographically.

We have used Mermaid to simulate the tow out and connection to three anchors of ten turbines at a site offshore of Wales, western France and in the Mediterranean.  Read more >

Subsea cable installation providers, Prysmian Group takes Mermaid® to reduce weather risk and optimise offshore operations.

  • Prysmian using Mermaid® to accurately model and plan worldwide cable installation jobs.
  • Mermaid® is the foundation of enhanced decision-making in the early planning stages that will lead to long-term cost savings.
  • Designed by JFMS, the software is in constant development and is vital to reducing the weather risk on marine operations.

Cable installation experts Prysmian has become the latest offshore operator to adopt Mermaid® to assess weather risk and accurately plan its various worldwide installation projects, supporting enhanced decision-making in the early planning stages that will lead to significant long-term cost savings.

Floating wind O&M case study: Comparing vessel access limitations for fixed and floating platforms

This is the first in a series of articles where we take a look at some of the challenges facing the development of floating wind and how Mermaid can be used to provide some answers and actionable intelligence.


copyright Morek Engineering 2020

As the development of Floating Offshore Wind Farms (FLOW) gathers pace from pilot projects to the planning of whole arrays there are a range of new technical challenges that need to be met.  One of these is the assessment of how vessels can access a floating turbine during O&M activities.  Read more >

Modelling wind farm installation in US waters

As the offshore wind industry gathers pace in US waters, we thought it would be a good time to illustrate the importance of simulating complex installation schedules to support efficient offshore planning.

It is common knowledge to the industry that US regulations mean that the installation of wind farms in US waters are restricted in their use of foreign vessels.  In particular, the ‘Jones Act’ dictates that vessels transporting goods between two US locations need to be US built, flagged and owned.  Read more >

Mermaid Release Notes v1.3.0.1

The latest release of Mermaid is now available. In this release we’ve made some changes to the metocean tab to improve its useability.

If you’re interested in Mermaid please get in touch.

New Features

MM-2333: Metocean Tab Redesign

We’ve redesigned the metocean tab to improve importing and data viewing experience.  This is particularly useful in files with a large number of metocean points (for example, if a user keeps a library type file of data).

Bug Fixes

We’ve fixed a few small bugs in this release:

MM-2272: Undo/redo reorders items in the map side bar. Read more >

Mermaid 2019 Upgrades

The past month has seen two significant software updates to Mermaid.  This article introduces these updates and explains what benefits they bring the user. If you’re not a current user and would like to know more, then try a free trial –  Get in touch!

Metocean Climatology Statistics Module

This significant upgrade of Mermaid sees the introduction of the Metocean Climatology Module and makes Mermaid one of the most diverse and comprehensive weather planning tools available.

It provides the options to generate both simple climatology statistics and complex simulations of marine operations together with a free metocean database. Read more >

Mermaid Release Notes v1.3.0.0

The latest release of Mermaid is now available. In this release there is only one new feature, but it is a big one which we have been working on for a long time.

If you’re interested in Mermaid please get in touch.

New Features

MM-2286: Metocean Statistics

It is now possible to generate overview metocean statistics, including probability of exceedance, persistence and occurrence stats and metocean distribution tables.  This is a large update to Mermaid and it, and some of our other recent developments, are discussed more fully here. Read more >
