The various program options for modelling the ambient ocean environment and its associated loading are discussed in the following sections:
•Environmental Parameters introduces some fundamental parameters such as water depth, density of seawater, the gravitational constant, and the kinematic viscosity of seawater.
•Buoyancy Forces outlines some basic theory relating to buoyancy loads.
•Buoyancy Formulations discusses two distinct options for specifying how buoyancy forces generated by elements are determined, Default and Distributed.
•Hydrodynamic Loading discusses how the various hydrodynamic forces are computed based on Morison’s Equation, including the three distinct components of drag, add mass and added inertia.
•Partially Submerged Elements outlines how the buoyancy and hydrodynamic load computations are adjusted to reflect the reduced areas and volumes associated with partially submerged elements.
•*OCEAN is used to specify general parameters defining the ocean environment.
