From an engineering point of view, tugs are small, powerful vessels designed to tow or push larger vessels in ports, harbors, and other waterways. They are typically between 20 and 40 meters in length, with a speed range of 8 to 16 knots. The deadweight tonnage (DWT) of tugs varies depending on their size and capacity, but they generally range from 100 to 500 tons.
The number of active vessels in the tug industry is difficult to estimate, as it varies by region and market demand. However, it is safe to say that there are thousands of tugs in operation worldwide, with many more under construction or in planning stages.
The maximum draft of tugs is typically shallow, as they are designed to operate in ports and harbors with limited water depth. The cargo capacity of tugs is also limited, as they are primarily used for towing and pushing operations rather than transporting goods.
Some of the main shipyards for building tugs include Damen Shipyards, Sanmar Shipyards, and Vard Group. These shipyards are located in countries such as the Netherlands, Turkey, and Norway, respectively. Other countries with a significant output of tugs include China, Japan, and South Korea.
