The 7300 hp large power ASD tug is a modern, high‑performance vessel designed for demanding harbour, escort, and coastal towing operations. Equipped with azimuth stern drive propulsion, it offers outstanding manoeuvrability, rapid response, and precise control in confined waters, making it ideally suited for assisting large container ships, tankers, bulk carriers, and LNG/LPG vessels.Powered by twin medium‑speed diesel engines developing a total output of approximately 7300 horsepower, the tug delivers high bollard pull and excellent free‑running speed. This power enables it to perform ship‑handling tasks in adverse weather and strong current conditions, as well as escort duties in exposed coastal approaches and port channels. The propulsion system typically drives two azimuthing thrusters with fixed or controllable pitch propellers, providing 360‑degree thrust and exceptional steering capability at both low and high speeds.The hull form is optimized for stability, seakeeping, and low resistance, with a high bow and flared lines to reduce spray and green water on deck. A strong fendering system is installed around the bow and sides to protect both the tug and assisted vessels during push‑pull operations. The deck layout is arranged for safe and efficient line handling, with clear working spaces and anti‑slip surfaces to support the crew in all weather.On the fore deck, a high‑capacity towing winch with escort capability is typically installed, fitted with synthetic or steel wire rope suitable for heavy‑duty ship handling. The winch is usually equipped with automatic tension control and emergency release functions to enhance safety during high‑load operations. At the aft, a towing hook or towing winch can be fitted to support coastal towing, barge handling, and additional harbour tasks. A sturdy towing staple and fairleads guide the lines and ensure safe working angles.The wheelhouse is arranged with almost 360‑degree visibility, providing the operator with clear sightlines to the bow, sides, and aft working areas. All major controls, including engines, thrusters, winches, and navigation equipment, are ergonomically grouped to allow one‑person operation when required. Modern navigation and communication systems, such as radar, electronic chart display, AIS, GPS, and VHF radios, support safe operation in busy ports and coastal routes.Accommodation is designed for a small crew, typically including cabins, galley, mess room, sanitary facilities, and storage spaces to support multi‑day operations if needed. Noise and vibration levels are minimized through resilient mounting and insulation, improving comfort and reducing fatigue.Overall, the 7300 hp large power ASD tug combines high bollard pull, excellent manoeuvrability, and advanced equipment to perform a wide range of towing and escort duties safely and efficiently in modern port and terminal environments.
