WinCAT is catenary analysis software for hanging cable systems including offshore moorings, umbilicals and flexible risers. Developed by Pisys and available on a day, month or year subscription, WinCAT is used for design analysis, installation studies, anchor laying, rig moves and subsea operations. The system has been developed by experts in the field to bring sophisticated and complex catenary analysis to any offshore practitioner.

  • Line Sections

    Model multiple line sections with different properties, so realistic mooring or cable arrangements can be represented clearly.

  • Buoys

    Add support buoys at any point along the line to reflect real-world offshore configurations.

  • Workboat

    Workboat option to handle line installation and laying

  • Modelling

    Account for sloping seabed and ground friction when site-specific seabed conditions matter.

  • Database

    In-built database of line properties including chain, wire, etc.

  • Customise

    User additions to database for lines, buoys and anchors

  • Switchable units

    Switchable units (Metric & Imperial) for input and results

  • Results

    Comprehensive results presented in tabular format

  • Graphic Plots

    Graphic catenary plots with multiple cases per plot allows comparison of operating scenarios.

  • Interact

    Interaction with plots for line details and measurements

  • Export

    Easy to export usable reports in Excel and PDF format

  • Collaborate

    Collaborate with others via email from within the website

WinCAT Software In Detail

New Data Creation

Set up critical data quickly and easily - Catenary Setup, Line Composition, Section Details, Line Deployment, Catenary Lines etc.

Dashboard

The Dashboard shows all existing projects within the system. Selecting a project will load the project edit screen with the Catenary Lines summary allowing the data to be modified, or the catenary results to be computed. From here a user can create a new project which leads into the sequence of data entry windows which allows new catenary lines to be set up, or import a file which will create a new project with information and Catenary Line setup extracted from the file.

Catenary Setup

WinCAT can handle any number of catenary lines. All lines are enabled by default. If the enabled check is cleared, then the catenary line becomes dormant. The data is retained, but no results are computed or available for printing.

Line Composition

A line is composed of one or more sections which are identified by their number. Every line must have a section which is attached to the vessel at the surface. All the sections defined for a line are shown in WinCAT under the Line Composition tab where the Line Type, Nominal Size, Length and Node Type are summarised.

Catenary Plot Tabs

The Catenary Plot tabs display the output from the computations in a series of tabs, one for each catenary line. The WinCAT catenary plots are accurately drawn and can be included in the printed output. Line Details provides a quick way to access the Catenary Setup for modifying the data of the selected catenary.

Results

The Results Table located under the Catenary Plots shows the numeric output from the computations for one catenary line in an easily understood tabular format. The results table can be included in the printed output, and the content and order of the results table can be customised so that only the information relevant to a particular analysis is given. Where there are several catenary lines in the dataset the Results Table relates to the selected Catenary Plot.

Cyber Essentials Plus Certified

Cyber Essentials Plus helps us guard our organisation against cyber attacks. This is important because vulnerability to basic attacks can mark us out as a target for more in-depth unwanted attention from cyber criminals and others. Certification gives us and our customers peace of mind that our defences will protect against the vast majority of common cyber attacks simply because these attacks are exploiting targets which do not have the Cyber Essentials Plus technical controls in place.

ISO 27001 Certified
