Ocean-going tugs are powerful boats designed to assist larger vessels, such as cargo ships and tankers, in navigating through open waters. They are equipped with strong engines and specialized towing equipment, allowing them to pull or push ships safely in harbors, through narrow channels, or during rough sea conditions. These tugs are built to withstand harsh marine environments and often have reinforced hulls for added durability. They play a crucial role in maritime operations, ensuring that vessels can dock, undock, and maneuver effectively, thereby enhancing overall shipping safety and efficiency in the shipping industry.
