This increased its stability and made recovery more difficult because of 

 the greater volume. Furthermore, the viscosity of the emulsion remained 

 very low in a sea temperature of 8 C, so that it behaved like an un- 

 emulsified oil and remained difficult to contain. In addition to the 

 seven cargo tanks, the port and starboard bunker tanks were also damaged, 

 leaking an unknown quantity of Bunker C. 



Oil leakage began immediately after grounding, and the oil was 

 blown by westerly winds of 2 to 4 m/s (5 to 8 mph) . About \\ hours 

 after the accident, the Coast Guard and pilots arrived and deployed 

 containment booms. Within another four hours, special units from the 

 Coast Guard arrived and deployed high seas booms on the leeward side of 

 the ship. 



Early the next morning, October 27, crews began recovery of the 

 oil, using suction pumps, skimmers, and other clean-up equipment (see 

 footnote), but shortage of support tanks for the deposition of the re- 



Footnote: The Swedish Coast Guard reports that the following material was 

 used during the Tsesis clean-up operations: 



1. Containment booms: High seas booms, Sea-pact 3 (1500 m) 



Bravur (200 m) 

 Coastal booms Expandi (2500 m) 

 Addition booms were deployed by local agencies. 



2. Coast Guard ships: 7 oil combatting vessels 



7 Coast Guard cutters 

 2 motor boats 

 4 work boats 



3. Other ships 4 tugboats 



4 barges 



5 tankers 



4. Oil recovery equipment: 2 Vikoma skimmers 



8 Komara skimmers (hydraulic) 



3 Vacuum pumps 



1 Lockhead skimmer 



3 belt skimmers adjusted to combatting vessels 



1 Marco oil recovery unit 



1 Petrolina belt skimmer 



1 Oil recovery unit (screw type) 



1 Framo-unit for "lightering" on-top 



5. Other equipment: 8 containers 



6. Reserve supply (not used): Approx. 1700 m containment booms, 

 2 Vikoma skimmers, 1 Framo unit, dispersants.

 clean-up techniques employed can be obtained from Captain Sven Uhler,
