Tanker safety slogan

Iran claimed responsibility for the detention of an oil tanker carrying petroleum products and chemicals after entering Iranian waters. The Iranian Revolutionary Guards said in a statement that due to repeated violations of marine environmental laws, the Iranian Revolutionary Guards seized the Korean oil tanker marked Hankuk chemi on 10, Iran time. Previously, a series of security incidents occurred in the Persian Gulf region. In recent years, with the increasing tension between Saudi Arabia and Iran, some ships have been attacked here. Iran's Revolutionary Guards said that when Iran intercepted the oil tanker, it had just left the port of Jubail in Saudi Arabia with 7,200 tons of petrochemical products. The semi-official farce news agency reported that the Revolutionary Guards had sailed to bandar abbas.

Earlier, Tasneem News Agency quoted people familiar with the matter as saying that Iran detained the ship because of environmental and chemical pollution in the Persian Gulf. According to reports, the arrested crew members came from South Korea, Indonesia, Vietnam and Myanmar. According to the ship tracking data compiled by Peng Bo, the tanker Hanku Chemical No.65438+was loaded at Jubail Port on12 October, and then sailed to Fujila Port in the United Arab Emirates. After entering the Strait of Hormuz, they turned to bandar abbas.

Once the oil tanker sinks, the disaster is irreversible, and the most striking thing is the ecological disaster caused by fuel leakage to the marine environment and surrounding wildlife. Tens of thousands of tons of fuel leaked from the Prestige oil tanker polluted a large area on the northwest coast of Spain. This coast is an important place for seabirds and other marine life to stay and migrate. A large number of seabirds live in the ocean and rarely fly to the shore. These birds, including puffins, three-toed gulls, long-nosed cormorants, black gulls with yellow legs and the critically endangered Barry Ali gull, are all fighting oil.

There are no more than three forms of fuel in the marine environment: floating oil film at sea, dissolved and dispersed state and concentrated residue. The oil film floating on the sea surface is the first killer of marine life and surrounding wildlife. Oil film is the initial state of fuel entering the ocean. A large amount of fuel leaks on the sea surface, which is difficult to volatilize and dissolve for a while. When it is blown to the shore by strong wind, it will form an oil film with a thickness of half a meter or even one meter. The opaque oil film reduces the light transmittance, affects the air-sea material exchange in the sea area, reduces the generation of oxygen in the ocean, and suffocates most marine life. At the same time, the oil film is destructive to the surrounding marine fisheries, especially shellfish and aquaculture. Not only ecological fisheries, but also marine tourism, marine mining and marine transportation will be seriously damaged.
