Feature 7 | NAVAL VESSEL REPAIRS AND REFITS
pre-compressed to facilitate installation, thereby saving considerable amounts of working time at the shipyard. Metalastik Super-D mounts are rubber/metal bonded assemblies specially developed for arduous marine applications. Tey are capable of nominal static deflection of 23mm and up to 50mm shock excursions in any direction. During the refits various configuration
changes were made to the two vessels, including a major stability and compartment modification according to a design provided by Australian Marine Technologies (AMT). Amongst other features, these changes extend the damage sustainment capability of the ships, while also making better use of the quarterdeck area. To this end the forward part of the quarterdeck has been fully plated in, adding to buoyancy, and new compartments created for a laundry and crew gymnasium. As a result there was a significant relocation of equipment on the quarter deck and internal structural changes to support the new bulkheads and relocated equipment.
One of the Super-D mounts of the type that Trelleborg has supplied to the New Zealand Navy. AMT was also involved in the upgrade
of the diesel engines. The company provided the design integration for systems external to the diesel enclosure including the ship systems and systems
interfaces. Part of this involved the conversion of the engine control system from electro mechanical to a solid state system interfaced to the existing Siemens C+M system. SCRT

Periods (AMPs) managed by Cammell Laird have also been carried out in 2010, both in the UK and overseas, as part of the ‘global reach’ element of the contract, which was originally signed in 2008 and which is renewed every five years. Vessels worked on
