MODU Wind Heeling Moments

Description

The IMO Mobile Offshore Drilling Unit method of calculating the wind force and moment on the structure has been implemented. To use this feature, all exposed above and under water elements, must be defined as compartments and assigned to a special category with an identifier, SL, and name, Sail. The program assumes that the specified Structural permeability is the Shape Factor for these elements. Also the wind moment must be set to the MODU wind moment, in the Criteria file.

Benefits

Allows stability assessment for MODU's.

Compatibility Constraints

None.
