covered oil delayed the work. Shortly after noon, the Soviet tanker 

 Talsy , a sister ship to Tsesis , arrived to assist in "lightering"; 

 however, this ship was refused permission to off-load Tsesis oil because 

 it had not been cleaned properly, and the danger of explosion was high. 

 Swedish authorities ordered barges, which arrived later that day, allow- 

 ing the recovery of oil inside the high seas boom to continue. 



Throughout the period, wherever floating oil was being transported, 

 trajectories were mainly dependent on wind and topography. This greatly 

 simplified tracking the surface oil, especially since the winds remained 

 steadily from the west until October 28. 



The part of the oil that had already escaped before any booms 

 arrived hit the shores of Toro, east of Svardsf jarden, during the after- 

 noon of October 27th (see map, Fig. 4.9). Periodically the wind became 

 strong enough to cause complete failure of containments, even when the 

 booms were in place. Additional booms were deployed along shorelines, 

 in sounds and in other areas where recovery of oil might be successful. 

 In some cases the oil was directed into bays where it could be collected 

 from the shores or from the sea. In all, about 6,600 m of containment 

 booms were used. 



In the early morning of October 28 a Swedish tanker arrived, pro- 

 viding greater storage capacity than the barges and, therefore, allowing 

 the recovery of oil to continue. The wind still complicated the work as 

 it turned southwest and increased in velocity to 4.5 to 5.8 m/s (10 to 

 13 mph) . This was responsible for complete failure of even the near- 

 shore booms, and the change in wind direction caused beach pollution 

 farther north along the shores of Liso Island (see photos, Appendix 2). 



During the following days, the recovery of oil continued both in 

 the proximity of the ship and in bays and sounds throughout the area. A 

 few hours after noon on October 31st, Tsesis was towed off the rock 

 where it had been firmly grounded for 5 days. She was then anchored in 

 Svardsf jarden (see Fig. 4.9 for map) until November 3, when she was 

 finally towed from the area for extensive repairs in Stockholm. The 

 winds remained steady from the south through November 1st.
