It was known that there were massive oillumps in advance, but…..
•The structure of recovery boats in our hand are notsuitable for highly viscous oil recovery operations.

•Further development of techniques of spilt oil recovery
with booms is necessary. (Structure of Booms / Training)•Since the efficiency of a bucket grab hopper barge was
not officially known, it was difficult to have an agreementon the increased usage of the barge.

•It took about 3 hours for an aircraft to convey theinformation to the MDPC regarding the location of the oillumps, but the information was no longer useful when it
was finally received.

Response to a Massive Oil Drift
Ashore on the Sand Beach•The usage of heavy machinery caused a massive
amount of sand to be mixed with the oil.

•The geographical features of the shore were changed
by being moved landward due to damage tovegetation by heavy machinery.

•A massive amount of the beach sand wascontaminated with oil, which was wasted anddisposed of. However, there were not enoughdisposal methods or facilities for the oily waste.

•Examination of the most suitable recovery methods--deployments--deployments of suction tanker trucks, beachcleaning machines, and etc.

From the Seaside
During calm sea conditions, the extraction operation was done
through the night, 3 times in total. A total of 2,800kl ofoiloil-water mixture was collected.

Construction of the Temporary Causeway
Soil and sand were washed out and eroded by waves, and it
took 26 days for the causeway to be completed.

Countermeasures to the Remaining Oil
Inside the Bow Section• Extraction is commonly conducted byconnecting a hose between thewrecked/grounded vessel and the ground,and pumping out the remaining oil inside thevessel.
• In the case of the other incidents that
require a construction of a causeway tocollect spilt oil in the future, objectives andproblems should be clearly stated.

Conclusion
1. We need to establish a system to obtain information
about the location and other details of massive oil lumps
in advance so that we can surely recover them.
２．Countermeasure systems to deal with a massive amountof oil to be washed up on the beach.
３．Extraction of the remaining oil in the grounded vessel…
vessel…
It should be considered whether to use the same
operational method. All these problems occurring due tothe construction of the temporary causeway must beclarified.
The above measures are to be taken in the early stagesof the incident, which could be in upset condition.
Therefore, they need to be written in a manual beforehand.
