Response Strategy Hard to deploy oil boom and skimmer owing to bad weather condition ою Strong S wind i d & hi high h wave were biggest obstacles
Protection of Environmentally Sensitive Areas was a top priority ою Most Sensitive Areas ( i hi (Fishing ffarms, Marshes, h Power Plant) l ) were protected by oil booms of 3-5 fold.
Dispersants was used to prevent oil-spreading over the off-sea
Initial Response Actions Oil Boom Deployed near the Tanker - OSRVs arrived at the tanker in 4 hours - 800 m Oil booms were deployed, but destroyed immediately
Patching g the p punctures of the tanker - At early stage, the patching was failure by not accessible to the tanker under bad sea condition - Majority of the oil escaped for 4 ~ 5hours at the beginning
Oil Transferring operation from the damaged tanks to Another Tanks - Coast Guard staffs arrived on board by y aircraft and took appropriate early actions
Response Actions at Sea Daily aerial surveillance had been carried out for the monitoring of oil spreading status for offshore response. Dispersants were used based upon those aerial surveillances. surveillances As the oil was emulsified and harden, operations were focus on the removal of tar tar--shaped oil using response vessels, fishing boats, skimmers,, nets and etc.
‹ Oil affected to the land 70km of shoreline and 101 islands were heavily polluted ‹ Relevant government arranged response activities - Normal beaches: volunteers - Dangerous areas (islands and cliffs): police, army, response agency Thick oil were collected by hands with buckets Shoreline equipment like beach cleaner and small skimmers were utilized in collecting g thick oil on the sand beach

1.
Insufficient Initial Response Actions
他
It was not able to implement immediate patching operations p against g p punctures of the tanker
他
It was not carried out to take earlier oil transferring operation of the tanker
2. 他
Ineffective Command Control System On--scene Command post HQ in Coast Guard and On Central HQ in Ministry (2 HQs)
3. Lack of Effective Management for Volunteers 他
Sudden huge no. of volunteers gathered as the incident reported via media
他
There were no regulations ready for volunteers management and problem of training, safety, material distribution raised.
他
It was settled ttl d as system t off registration, i t ti guidance id and d other th volunteers managements provided by local authorities
4. Endpoint and compensation Issues caused conflicts 他
Disputes were made between experts and local peoples (experts prefer natural cleanup while local peoples want more complete cleanup)
5. Issues related to Response Techniques 他
Failed to predict the spreading direction of spilt oil?
他
Appropriate use of dispersants?
他
Excessive shoreline cleanup?
IV. Improvements after the spill
Prevention System reinforcement Appropriate Role Sharing in VTS control Coast Areas VTS : Coast Guard, Port VTS : Ministry (Joint with Coast Guards)
Earlier Phasing out of Single Hull Tanker Timeline of Single hull prohibited : 2015→ 2015→2010
Unified Command System (Role of Each body) Korea Coast Guard – Commander and Controller in Response Ministry – Environment Restoration Local government – In chare of Shoreline Cleanup, Volunteers management
IV. Improvements after the spill
Amendment of NCP and Regional Action Plan More Practical Manual for Large oil spill incident Detailed Role of Each Government Body Management of Volunteers and System of Emergency Resource Deployment Preparedness of HNS Incidents
Revised National Response Function and Capability Restructure of Oil Spill Response - 3 National Strike Teams were established
Building up Big Response Vessels - G/T3000 Multi Multi--purpose vessels
Response Stockpile – 3 areas
