Floater motion components

The Floater motion tab defines a list of individual Floater Motions that may be used to define combined environments from the Combination matrix tab.

Warning

Floater motion components apply to Floater components only.

The Floater motion tab includes the following items:

  • Number of motions: The number of Floater Motion components must be set with the spin box located in the upper right corner of the tab. You may either use the up/down arrows to setup the number of Floater Motions, or input any value using your keyboard and then pressing the ENTER key. Pressing the ENTER key confirms the number of individual components to be included and generates the main Floater Motion data table with appropriate number of rows.

  • Insert new motions: Pressing this button inserts a new row in the Floater Motion data table.

  • Remove selected motions: Pressing this button deletes the selected rows from the Floater Motion data table.

  • Floater Motion data table: This table is used to define the Floater Motion data. This table includes 3 columns, as follows:

    • Name: This assigns names that will be used to refer to the Floater Motion components in the Combination matrix tab.

      Note

      Be careful to name Floater Motions uniquely to avoid confusion with Floater Motion Types. An example of names that could be used is "Floater component name" + "Floater Motion Type", e.g. "FPSO_RAO_Ballast", or "FPSO_RAO_Fully_Loaded", etc.

    • Object: Used to select the Floater included in the Floater Motion component. Each cell in this column contains a drop-down list filled in with the names of all Floaters components available in the model.

      Note

      Several Floater components may be used in the Object column. This is useful in case the model includes several vessels such as FPSO and CALM buoy, each of these being associated with an appropriate Floater Motion Type.

    • Floater Motion: This selects the Floater Motion Type that is to be assigned to the Floater. Each cell in this column contains a drop-down list filled in with the names of all Floater Motion Types available in the model.

      Hint

      Several Floater Motion Types may be associated to the same Floater component in separate Floater Motion components. To this purpose, you should set the number of Floater Motion components equal to the number of Floater Motion Types applicable for the Floater, and then assign the different Floater Motion Types to the Floater in these Floater Motion components. This allows for example to easily set combined load cases featuring different dynamic motion properties with the same Floater (e.g. FPSO with fully loaded draft, mid-laden draft, and ballasted draft).

Each Floater motion component is defined through a Floater component and associated Floater Motion Type which allows determining the dynamic response of the Floater to environmental loads.
