Abstract:
Smoke measurements were taken during the 1993
Newfoundland Offshore Oil Burn Experiment using a helium
filled miniblimp tethered to a vessel operated
approximately 300 m downwind of the fire. The smoke
sampling package suspended from the miniblimp consisted
of sampling pumps which drew smoke through either a
cascade impactor or filter and discharged gas samples
into collection bags. The smoke yield and smoke
particle size distribution were found to be similar to
previous measurements made for crude oil. The smoke
yields of 14.8 to 15.5% of the mass of the fuel burned
were measured and 83% of the particulate mass was below
9.8 mum in diameter as measured with a cascade impactor.
Measurements of temperature, wind speed, and wind
direction taken before and after the burns from the
ocean surface to an altitude of 300 m using the tethered
miniblimp and a radio telemetry weather station are
reported.
