www.marinelink.com MN 13 Dutch shipbuilding company Damen has launched a new Compact Stan Tug Series. The three new tug types in the series, the Stan Launch 804, Stan Tug 1004 and Stan Tug 1205 are designed to be strong, high- ly maneuverable and easily manage- able for a one or two-man crew. The new vessels are suited for towing, pushing, mooring, line handling, pas- senger transport, surveying and pilotage. Over the past two years a Damen product group has focused on improving the smaller tugs. Many details, components and systems inherent in the Stan Tug 1606 have been introduced in the new range. During the design process much attention was paid to creating the optimum hull design. Damen’s own Research Department made recom- mendations based on full-scale tests, detailed calculations of structural strength, fatigue, frequencies and wave profiles. In addition, the propulsion system was improved, leading to lower noise levels, a faster speed and a higher bollard pull. During the trials, the Stan Launch 804, the Stan Tug 1004 and the Stan Tug 1205 exceeded the expectations of the design team. Like other Stan Tugs the new range can be complete- ly built from stock. The possibility to introduce optional extras such as a deck crane, flying bridge, radar and extra accommodation can be carried out quickly because these are all held as standard components on stock. The Stan Tug 1205 has a robust all- welded steel hull, with 10mm thick hull plating and a 15mm sheer strake. Even the smallest from the series has been built with a strong push bow and the hull has an optimum form to facilitate a smooth inflow of water around the propellers and rudder. Where the Stan Tug 1907, 1606 and 1205 are twin-screw vessels, the Stan Launch 804 and Stan Tug 1004 are single-screw tugs. Both the fore and aft decks in the new series have been developed to have as few obstacles as possible to obtain the maximum amount of space for safe working conditions. Mooring bits, the engine room hatch, ventilation equipment and the exhaust pipe outlets are built in to facilitate optimum ease of use, safety and simple maintenance. All the Compact Stan Tugs are pro- vided with lifting eyes and they are equipped with a single anchor, han- dled by an electrically driven wind- lass, with the exception of the Stan Launch 804. The new Stan Tugs have full, electronic-controlled Volvo D5 and D9 main engines. Damen’s propulsion system is incorporated which comprises two manganese bronze propellers in high perform- ance Van der Giessen Optima noz- zles. The nozzles are lined with stain- less steel. The vessels maneuvers well with two streamlined double-plate rudders with rudder angles of 2 x 55°. An electrically driven Sterling bilge and general service pump has a capac- ity of 14 cu/m of water per hour. A manual emergency pump is located in the engine room as well. Engine cooling is provided by a Damen system with a closed circuit keel cooling system so the vessel can operate in extremely shallow water. For the 1205 and upwards, electric power of 230V - 24V is supplied by an Onan 18kVA auxiliary generator. A double 24V battery pack, with a changeover possibility, is used for starting the engine and domestic use. The complete wheelhouse is mount- ed on rubber shock absorbers and together with the modern linings and insulating material, this ensures a low noise level of 55 dBA. www.damen.nl BOAT OF THE MONTH Damen’s Compact Stan Tug Photo courtesy Damen Shipyards Gorinchem
