As per the exercise legend, as a result of partial damage of the hull oil products spilt from Vilsand tanker (cargo carrying capacity – 35,000 tons) loaded at berth № POT-3. As per the exercises legend, 1,500 tons of oil products leaked out of the tanker. Consequently, an oil patch of 50mx80m is adrift towards the Krasnen’kaya river estuary.
A diving ship Vodolaz-15 was deployed in the exercise. A group of divers was carrying out works on special patch fixing onto the damaged vessel hull. Two motor-boats booms-fixers Aliot and Arneb installed the second line of booms from berth № POT-1 to the west end of berths POT-3 and 4.
Upon booms fixing the two motor-boats and Vyborg vessel proceeded with oil collecting using skimming systems. The collected oil-water mixture was pumped into Viking (owned by shipping line Delta) tanker for temporal storage.
Main efforts in OSR works were focused on stoppage of oil products spill from Vilsand, oil spill containment, oil-contaminated waters collection, prevention of oil patches transfer into the coastline.
