solution utilises abrasion-resistant stainless steel to conserve the carefully designed shape of the stator blades in order to retain high levels of fuel efficiency. The impeller and shaft are also constructed from stainless steel. “Tis enhanced midsize waterjet series makes Wärtsilä
extremely competitive for a vast array of high-speed vessel applications. Te ease of installation, the reliabil- ity, and the overall attention to detail that these waterjets incorporate, puts them at the forefront of developments in this field,” said Aaron Bresnahan, vice-president, Special Vessels Segment, Wärtsilä Ship Power. Te waterjets come in a fast and easy ‘plug and play’
installation module that offers owners and shipyards lower installation costs and simplified build schedules. Te packaged delivery has inlet duct shapes optimized for different hullforms, thus freeing the yard from the responsibilities of inlet duct construction.

for Audacious BAE Systems (Submarine Solutions) has chosen iXSea MARINS inertial navigation systems for HMS Audacious, the fourth boat in the UK Royal Navy’s Astute class, nuclear-powered attack submarines.
CAD/CAM QinetiQ GRC introduces latest version of Paramarine
QinetiQ GRC, the developers of Paramarine, the marine design tool, has released its latest version of the software which includes many new capabilities and features. The new functionality in Paramarine V7 is intended to improve and enhance the design process, with a focus on reducing cost through reduce design cycle times and the mitigation of design risk due to the increased understanding of the design space.
The latest release introduces the ability for ship designers to work concurrently on the same vessel design which reduces the length of the ship design cycles further advantages include improved design configuration control. This functionality will allow users to significantly reduce their time to market or it will allow them to perform further analysis within the same timeframe, significantly reducing the design risk.
Paramarine V7 also includes the ability to integrate with Siemens NX software. The benefit to ship designers is that naval architectural analysis can be rapidly conducted using the master geometry dataset as defined within NX.
A major improvement in V7 is an overhaul of its reporting functionality. The completely new reporting tool is flexible, user friendly and will allow users to quickly create reports on any data held within Paramarine. This will allow users to quickly set up reports and export them to Microsoft Word, create PDFs or print directly from Paramarine.
The most important feature of the new reporting capability is its ability to automatically update its contents: the links to the data are ‘live’ and any changes in the underlying calculations will cause the report to automatically refresh itself. This means that changes to the underlying vessel geometry will automatically recreate the contents of the report with the updated calculations, requiring no further user input significantly reducing the cost and time to create professional reports as the design evolves.

HMS Audacious will be equipped with two MARINS units. iXBlue will also supply a third unit for preliminary test work at BAE Systems’ Astute shore integration facility and provide engineering and project management support for the installation of the units on board the submarine. BAE Systems has options on further MARINS units for Astute- class boats five, six and seven.
MARINS has been selected for installation on HMS Audacious.
