Another Dance of Death.
The USCG report does not mention a spill,
so apparently the penetration was aft of the cargo tanks,
but why no bunker spill?
This collision was studied by Brown et al in SSC Report SR-1426
using the SIMCOL model and finite element,
both of which came up with DOP's and LOP's
which were quite close to the reported values
using 9.5 knots for the Adventurer, 8 knots for the Tullahoma,
and a 90 degree angle.
