I am fairly new to OpenFOAM, so please bear with me. I am looking to set up an atmospheric flow around an offshore platform. The inlet wind conditions can be set by using the atmBoundaryLayerInletVelocity BC. I am wondering about the other BCs, however. What are the best BCs for the sides, top, outlet and bottom of the domain? The bottom of the domain is assumed to be water (flat). Also, what are the best BCs for the structure itself? My physical variables are velocity, pressure, k and epsilon.

So far I am thinking the following, please correct me where I am wrong and fill in where I am wondering:

Velocity:
- Inlet: atmBoundaryLayerInletVelocity
- Outlet: ???
- Sides: ???
- Top: slip ???
- Water: fixedValue 0
- Walls: fixedValue 0

Pressure:
- Inlet: inletOutlet
- Outlet: outletInlet
- Sides: ???
- Top: ???
- Water: zeroGradient
- Walls: zeroGradient

k and epsilon:
- Same as for velocity?

Any comments are highly appreciated! Are there any good references for descriptions of the BCs other than Doxygen?
