NewZealand's KiwiRail says that the Interislander ferry Arahura has left Wellington for her scheduled bi-annual dry-docking in Devonport, having last visited Auckland in July 2012. Docking is being undertaken at the Devonport Dockyard under the management of Babcock’s New Zealand. The principal work relates to the vessel’s regulatory compliance regime, which requires machinery and propulsion equipment to be inspected and if necessary, repaired. Work to be carried out while the vessel is in dry dock includes tail shaft removal, an overhaul of the propeller hub, and crack testing of all propeller blades and securing bolts. Arahura’s rail deck will undergo routine track maintenance which will be completed by the KiwiRail track maintenance team.
