Damen Marine Components (DMC) has completed the supply and installation of a number of critical systems for the Antarctic Supply Research Vessel (ASRV) Nuyina being built for the Australian government’s Antarctic Division.
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 have been designed and engineered by project-lead Damen Schelde Naval Shipbuilding as free-hanging, full-spade rudders.
To deliver all the necessary steering system components from the bridge to the rudder, including hydraulics, control and power systems, DMC partnered with 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 its Poseidon series.
DMC delivered the rudder system, neck and carrier bearing systems steering gear foundations, electrical system, and the primary steering control system.
DMC also worked with Lloyds Register’s polar division throughout the process to ensure that the required standards were established and achieved.
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, the company explained.
The ASRV is being built at Damen Shipyards Galati and is due to be delivered in April 2020.
