During the cleaning and repair period, we maintained telephone contact with the workers and crew, and provided corresponding suggestions for the cleaning measures. According to the crew's message, after cleaning the cargo tank top, they opened the cover of the bilge well and found that it was filled with fuel. We advised the workers to first remove the fuel, then used a mixture of oil dispersant to soak the pipes, constantly replaced the contaminated dispersant until there were no more oil traces inside, and then rinsed with clean water. All oily water was sent ashore for treatment. During the boarding inspection on July 27th, we found that the bilge well was clean and there were no obvious oil traces. At the same time, the crew opened the pipes to check the condition of the internal filters and found no contamination. However, there were still a small amount of oil stains on the surrounding part of the hatch. The workers continued to clean using a mobile platform. The cleaning work finally ended at 0800 on July 28th.
