Description

Added Mass Coefficients:

The name of the external data file which contains the added mass data. Refer to Added Mass Coefficients for further information on the file format. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should leave this entry blank.

Radiation Damping Coefficients:

The name of the external data file which contains the radiation damping data. Refer to Radiation Damping Coefficients for further information on the file format. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should leave this entry blank.

Reference Frequency:

The reference frequency to be used in determining the added mass of the floating platform. Refer to floating body Hydrodynamic Theory for further information on the convolution integral technique employed by Flexcom to model frequency dependent added mass and radiation damping terms in a time domain simulation.  

Normal Added Mass Coefficient for All Members:

The added mass coefficient in the direction normal to each structural member. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should specify a realistic added mass coefficient here. If you are using the more detailed Radiation-Damping approach, you should leave this entry blank.

Tangential Added Mass Coefficient for Outer Columns' Base:

The added mass coefficient in the direction tangential to the base of each outer column.  Flexcom does not model hydrodynamic loads on element end faces directly, so the tangential component of Morison’s Equation may be used to simulate loads on the relatively large circular area at the base of the outer columns. If you are using the more detailed Radiation-Damping approach, you should leave this entry blank.

Normal Inertia Coefficient for All Members:

The inertia coefficient in the direction normal to each structural member. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should specify a realistic added mass coefficient here. If you are using the more detailed Radiation-Damping approach, you should leave this entry blank.

Description

Force RAOs:

The name of the external data file which contains the force RAO data. Refer to Force RAOs for further information on the file format. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should leave this entry blank.

QTF Coefficients:

The name of the external data file which contains the QTF data. Refer to QTF Coefficients for further information on the file format. If you are modelling the floater hydrodynamics via the simplified Morison’s Equation approach, you should leave this entry blank.

Description

Normal Drag Coefficient for Main Column:

The drag coefficient in the direction normal to the central column.

Normal Drag Coefficient for Outer Columns' Upper Section:

The drag coefficient in the direction normal to the upper section of the outer columns.

Normal Drag Coefficient for Outer Columns' Base Section:

The drag coefficient in the direction normal to the base section of the outer columns.

Normal Drag Coefficient for Cross Braces:

The drag coefficient in the direction normal to the cross braces.

Tangential Drag Coefficient for Outer Columns' Base Section:

The drag coefficient in the direction tangential to the base section of the outer columns. Flexcom does not model hydrodynamic loads on element end faces directly, so the tangential component of Morison’s Equation may be used to simulate loads on the relatively large circular area at the base of the outer columns.

Tangential Drag Coefficient for All Other Members:

The drag coefficient in the direction tangential to each structural member.
