Yes, an LNG tanker can potentially explode if there is a significant leak of the liquefied natural gas and it comes into contact with an ignition source. LNG is highly flammable and can ignite if it reaches its flammable range in the air. However, LNG tankers are designed with safety measures such as double-hull construction, insulation, and pressure relief systems to minimize the risk of explosion. Additionally, strict regulations and safety protocols are in place to prevent and mitigate the risk of LNG tanker explosions. **

Oil tankers typically travel at speeds between 12 to 20 knots, which is equivalent to approximately 14 to 23 miles per hour. The speed of an oil tanker can vary depending on factors such as the size of the vessel, weather conditions, and the distance it needs to travel. Despite their large size and weight, oil tankers are designed to be efficient and capable of reaching their destinations in a timely manner. **

The world's largest tanker is the ULCC (Ultra Large Crude Carrier) known as the Seawise Giant, later renamed the Jahre Viking. It had a length of 1,504 feet (458.46 meters), a width of 226 feet (68.86 meters), and a depth of 81 feet (24.72 meters). The ship had a deadweight tonnage of over 564,000 tons, making it the largest ship ever built. **

A tanker typically has multiple cylinders, with the exact number depending on the size and design of the tanker. Large tankers used for transporting liquids such as oil or chemicals may have multiple cylindrical compartments, each with its own cylinder, to separate and store different types of cargo. These cylinders are designed to safely contain and transport the liquids while the tanker is in motion. **

Yes, a milk tanker driver does need an ADR (Accord européen relatif au transport international des marchandises Dangereuses par Route) certificate if they are transporting hazardous materials such as chemicals or gases along with the milk. The ADR certificate is required for drivers who transport dangerous goods by road in Europe, ensuring they have the necessary training and knowledge to handle and transport hazardous materials safely. If the milk tanker driver is only transporting milk and no hazardous materials, then an ADR certificate may not be necessary. **

Yes, a milk tanker driver does need an ADR (Accord européen relatif au transport international des marchandises Dangereuses par Route) license if they are transporting milk in bulk quantities that exceed the threshold for hazardous materials. Milk itself is not considered a hazardous material, but if the quantity being transported exceeds the threshold, the driver would need an ADR license to comply with regulations for transporting dangerous goods. **

The capacity of an oil tanker can vary widely depending on its size and design. However, a typical large oil tanker can carry anywhere from 1 million to 2 million barrels of oil, which is equivalent to 159 to 318 million liters. Some of the largest oil tankers in the world can even carry up to 3 million barrels, or around 477 million liters of oil. **

A fuel tanker is never completely filled with gasoline because there needs to be space left for the gasoline to expand. When gasoline is heated, it expands and can create pressure inside the tanker. If the tanker is completely filled, there is no room for the gasoline to expand, which can lead to potential safety hazards such as the risk of the tanker bursting or leaking. Therefore, leaving space for expansion is a safety measure to prevent accidents and ensure the safe transportation of gasoline. **
