    Damen Marine Components completes supply of unique rudder and steering gear system to ice breaker

    In an important milestone in the build of the Antarctic Supply Research Vessel (ASRV) Nuyina for the Australian government’s Antarctic Division, Damen Marine Components (DMC) has completed the supply and installation of a number of critical systems, the company said in its release. These had to be fabricated to exceptionally high standards to cope with the ice that the vessel will encounter in the Southern Ocean. DMC, under its Van der Velden Marine Systems brand, is responsible for the detail engineering and manufacturing of the rudder and steering gear system.

    The rudders in particular are unique. They have been designed and engineered by project-lead Damen Schelde Naval Shipbuilding as free-hanging, full-spade rudders. These deliver optimum hydrodynamic properties but until now were unheard-of for an icebreaking vessel of this class, given the forces involved. Other innovative features include the integrated mechanical rudder stoppers, which are located between the rudder blade and (hull) skeg structure rather than on the outside hull due to the latter’s radical design.

    To deliver all the necessary steering system components from the bridge to the rudder, including hydraulics, control and power systems, while meeting the unprecedent performance requirements, DMC pooled its expertise in this field with that of MacGregor Hatlapa (MacGregor). Working to DMC’s specifications, MacGregor manufactured and supplied the steering gear assemblies and the hydraulic systems that power them based on a highly-customized version of its proven Poseidon series. DMC delivered the rudder system, neck and carrier bearing systems steering gear foundations, electrical system, and the primary steering control system.

    With so many of the systems breaking the boundaries of normal icebreaker design and build, DMC worked closely with Lloyds Register’s polar division throughout the process to ensure that the required standards were established and achieved. The results of this cooperation include rudders that are by far the heaviest per square metre that DMC has ever built and rudder stocks with a diameter of over a 1000 mm. This together with the materials used made them very challenging to manufacture and install.

    These premium specification components are vital to the safe and reliable operation of the vessel. Its combination of icebreaker classification and high polar class notation creates the need to enhance its structural integrity such that, while the maximum design speed of the vessel is actually around 16 knots, most of the components have had to be designed to cope with theoretical speeds in excess of 31 knots.

    This joint-venture approach was chosen due to DSNS requiring proven technology and a single supplier, yet the specifications were such that no standard products available from DMC and its leading competitors came close to being able to withstand the expected forces.

    While being only 160-metres in length, the stresses imposed on the hull and its components are equivalent to those found on a normal vessel of 300 metres or more. MacGregor, with an existing product that would deliver the necessary performance after some modifications and a head office just 20 minutes from the DMC engineering department in Hamburg, was the ideal partner.

    The ASRV is being built at Damen Shipyards Galati and is due to be delivered in April 2020.

    Damen Shipyards Group
    Damen Shipyards Group operates 36 shipbuilding and repair yards, employing 12,000 people worldwide. Damen has delivered more than 6,500 vessels in more than 100 countries and delivers around 175 vessels annually to customers worldwide. Based on its unique, standardised ship-design concept Damen is able to guarantee consistent quality.

    Damen’s focus on standardisation, modular construction and keeping vessels in stock leads to short delivery times, low ‘total cost of ownership’, high resale values and reliable performance. Furthermore, Damen vessels are based on thorough R&D and proven technology.

    Damen offers a wide range of products, including tugs, workboats, naval and patrol vessels, high speed craft, cargo vessels, dredgers, vessels for the offshore industry, ferries, pontoons and superyachts.

    For nearly all vessel types Damen offers a broad range of services, including maintenance, spare parts delivery, training and the transfer of (shipbuilding) know-how. Damen also offers a variety of marine components, such as nozzles, rudders, winches, anchors, anchor chains and steel works.

    Damen Shiprepair & Conversion (DSC) has a worldwide network of eighteen repair and conversion yards of which twelve are located in North West Europe. Facilities at the yards include more than 50 floating (and covered) drydocks, including the longest, 420 x 80 metres, and the widest, 405 x 90 metres, as well as slopes, ship lifts and indoor halls. Projects range from the smallest simple repairs through Class’ maintenance to complex refits and the complete conversion of large offshore structures. DSC completes around 1,300 repair and maintenance jobs annually, both at yards as well as in ports and during voyage.
