For this set of loads:


1) W (OPE)

"W" will be the usual (air) weight of the system.

For this set of loads:

1) W (OPE) ---------- W will be the buoyant weight of the system (W+BUOY)
2) WAV1 (OPE) ------- WAV1 will be the effects of only the 1st wave vector
3) W + WAV1 (OPE) --- will be the combined effects of (W+BUOY+WAV1)
