Table 2 Main field trials completed on oil or gas sub-sea releases (Guyomarch 2002)
From: Dispersants as marine oil spill treating agents: a review on mesoscale tests and field trials
Date | Field test name | Objective | Description | Observations |
|---|---|---|---|---|
1975 | Topham | Check-up of OILMAP model predictions | Release of air from 60Â m deep | Â |
1983 | Milgram | – | Gas release from 50 m deep |  |
1995 | Norwegian sea trials (Brandvik et al. 1996) | Pipeline rupture Simulation | Low pressure oil release from 100Â m deep | Large oil droplets which reached the sea surface quickly |
1996 | Norwegian sea trials (Rye and Brandvik 1997) | Sub-sea blowout simulation | High pressure oil (60m3) with air release from 102 m deep | Small oil droplets Natural dispersion (only 10–20% of oil reached the sea surface) |
2000 | Deep Spill (Johansen et al. 2001) | Sub-sea blowout simulation | 4 releases (oil, seawater, gas) from 850Â m deep | Total dissolution of gas in the water column Oil reaches the surface in one hour |
