The ships of the Don Inda class , also known internationally as the Neptun Class and Ulstein Zamakona Neptun Series, are Spanish ocean salvage tugs designed as multipurpose ships belonging to the Sociedad de Salvamento y Seguridad Marítima . The ships sail with their home port Santa Cruz de Tenerife under the flag of Spain . They serve to ward off danger in the event of an average.
The Don Inda is the lead ship of the class. She is responsible for the Galicia operational area and is stationed in Corcubión . The sister ship Clara Campoamor is responsible for the operational area of the Strait of Gibraltar and is stationed in Algeciras .
The ships are part of the Spanish emergency towing concept . In addition to the possibility of using the ships as tugs ( emergency and rescue tugs), they can also be used in the event of oil accidents and fires at sea, and as a rescue ship.
Technology and equipment
The ships are based on a design concept for 80 m anchor -handling tugs from Rolls-Royce (UT 722), which was slightly modified for emergency towing, and were built on the Zamakona Yards near Bilbao. It is powered by four eight-cylinder - diesel engine with a power of each of 4000 kW . Two motors each act on a controllable pitch propeller , whereby the ships can be operated with all four or only two motors. To increase efficiency, the propellers are equipped with a Kort nozzle . In addition, the ships have a bow and two stern thrusters, each equipped with adjustable propellers, and a propeller pod in the bow area.
The ships are equipped with a dynamic positioning system. They have a range of around 9,000 nautical miles . They have a bollard pull of 228 tons , making them one of the strongest tugs in Europe. The 300 t towing winch acts on 83 mm towing cables and is equipped with a 550 t braking device. Another 45 t winch is installed on the foredeck.
The ships have several extinguishing monitors for fire fighting . To combat oil spills at sea, they are equipped with oil skimmers on both sides . The tank capacity for extracted oil is 1749.8 m³, whereby thanks to the available separators the oil can be separated for the most part from the water initially absorbed. There is only up to 5% water in the tanks.
The deck superstructures are arranged in the front area of the ship. Behind it is an open working deck. There are two working cranes with a capacity of 20 tons each. At the stern of the ships there is a stern boom with a capacity of 50 tons.
With a bow reinforcement the tugs can also maneuver damaged ships, i.e. H. push. This is particularly important for establishing a suitable alignment against wind and swell.
