Description

Platform Mass:

The mass of the floating platform.

Platform Ballast:

The total mass of the water ballast which is contained within the platform's columns.

Centre of Mass Location:

The platform's centre of mass location, measured vertically from the base of the central column. The total mass and rotational inertia of the floating platform is concentrated at this point.

Centre of Buoyancy Location:

The platform's centre of buoyancy location, measured vertically from the base of the central column. Buoyancy forces on the floating platform, which are modelled via linear hydrostatic stiffness terms, are concentrated at this point.

Roll Inertia:

The inertia about the local roll axis.

Pitch Inertia:

The inertia about the local pitch axis.

Yaw Inertia:

The inertia about the local yaw axis

Input:

Description

Heave:

The hydrostatic stiffness in the local heave direction.

Roll:

The hydrostatic stiffness in the local roll direction.

Pitch:

The hydrostatic stiffness in the local pitch direction.

Heave-Pitch:

The hydrostatic stiffness coupling term between heave and pitch.
