The Gyeongnam Province announced that around 9:49 AM on the 11th, an accident occurred where 8,400 liters of diesel fuel were spilled into the sea near a naval vessel at the naval pier in Jinhae-gu, Changwon City. Accordingly, Gyeongnam Province dispatched fishery guidance vessels to the site to actively respond to the oil spill, including prevention work and on-site verification, as there are mussel aquaculture farms near the fuel spill area to prevent secondary damage to nearby aquaculture farms. Additionally, by establishing a close cooperation system with Changwon Coast Guard and actively cooperating in prevention work, it was confirmed that there is currently no secondary damage to the marine environment or aquaculture farms after the emergency prevention work was completed.
