The Vancouver City Council of Canada confirmed on April 9 that a fuel leak occurred in Vancouver's English Bay. The city government issued an alert at 6 am on the 9th to call on people to stay away from the accident waters.

The emergency response department of the City of Vancouver said that the leak was from the fuel of the ship, which was poisonous. The local police said that when they discovered it, they could already see a large piece of oil on the water surface with the naked eye, and now the oil is being washed along the waves to the shore.

The Coast Guard said that a grain carrier named MARATHASSA in the accident waters was thought to be related to the fuel leak, which was surrounded by oil. According to the relevant investigators, if the ship regularly uses the thermal imaging camera to detect oil leakage on the ship's oil pipeline, the infrared camera can provide accurate leakage regardless of the harsh sea conditions, dazzling sunlight or all-black environment. Oil real-time video and image analysis. The advantage of doing this is that it will find hidden dangers as early as possible to avoid the accident of large-scale fuel leakage, and the damage caused by such accidents to the marine environment and underwater organisms is also huge.

Small science:

The oil leak detection principle is based on the difference between oil and water in temperature, heat reflection and thermal emissivity. Due to the difference in thermal conductivity, the oil usually absorbs heat very quickly during the day, so it is warmer than the surrounding sea water and appears as a hot spot on the thermal image. At night, the situation is just the opposite: the heat release rate of the oil body is faster than the surrounding sea water, so the oil shows a low temperature zone on the thermal image.
