The 7200 hp ASD tug is a compact but extremely powerful vessel designed for modern harbor towage, offshore support, and escort operations. Equipped with azimuth stern drive propulsion, it offers outstanding maneuverability, allowing it to turn within its own length and maintain precise control in confined waters and crowded ports. This high level of agility is especially important when working alongside large container ships, tankers, and bulk carriers during berthing and unberthing.With a total installed power of about 7200 horsepower, the tug delivers high bollard pull, typically in the range required for handling the latest generation of large vessels. The propulsion system usually consists of two medium-speed diesel engines, each driving an azimuthing thruster. These thrusters can rotate 360 degrees, providing thrust in any direction and enabling rapid changes in heading, sideways movement, and dynamic positioning close to the hull of assisted ships.The hull form is optimized for both escort performance and stability. A wide beam and low center of gravity ensure excellent transverse stability and predictable behavior under high towing loads. The bow is often shaped for indirect escort forces, allowing the tug to generate braking and steering forces when operating at higher speeds ahead or astern of a ship. Fenders of heavy-duty rubber are fitted around the bow and sides to protect both the tug and assisted vessels during pushing, pulling, and contact maneuvers.On deck, the tug is normally fitted with a high-capacity towing winch arranged either forward, aft, or both, depending on its primary role. The winch is equipped with tension control and emergency release functions to ensure safety during demanding towing and escort operations. A strong towing hook or staple guides the towline, and a robust deck layout allows the crew to work efficiently while minimizing exposure to hazards. Ample deck lighting supports 24-hour operations in all weather conditions.The wheelhouse is designed for all-round visibility, with large windows and an ergonomic console layout. Controls for engines, thrusters, winches, and navigation systems are integrated to permit single-operator handling when needed. Modern navigation and communication equipment, including radar, GPS, AIS, and VHF radio, support safe operations in busy harbor approaches and offshore fields. Vibration and noise reduction measures improve crew comfort and reduce fatigue on long shifts.Accommodation spaces typically include cabins, galley, mess room, sanitary facilities, and storage, allowing the tug to operate continuously with a rotating crew. Firefighting capabilities can be enhanced with a FIFI system, enabling the tug to assist in emergency response to shipboard or terminal fires. Overall, the 7200 hp ASD tug combines high power, precise maneuverability, and robust construction, making it a versatile workhorse for modern port and offshore operations.
