Aveva has responded to customer demand for more intricate, specialist modelling of specific vessel areas.


C


AD has come a fair way since the days when it was treated primarily as a set of building blocks for


new vessels. Since the technology and soſtware have become more widespread, the marine industry has learned to adapt these systems for a whole host of niche and specialist tasks, and is coming to demand software packages that enable them to hone in on specific areas of interest. Speaking to Ship & Boat International,


Stéphane Neuvéglise, product strategy manager at CAD/CAM software developer Aveva, identifies a number of recent marine user trends. “We’re seeing a lot more demand for integrated systems, particularly when it comes to integrating with 3D modelling soſtware”, he says. “Modules are becoming more complex. Management of onboard space has also become a big issue, with users wanting to define sections of the ship and break them down into zones – so, for instance, labelling certain ship sections as ‘Safety of Life At Sea [SOLAS] zones’ and working purely on these, or determining ‘painting areas’ for future maintenance or repair projects.”


The Aveva Space Management module allows users to subdivide vessels into distinct zones.


Management module As a result, the group has incorporated a new module, Aveva Space Management, into its recently released Aveva 12.1 tool, whose wider features include upgraded reporting options - enabling users to create report templates and incorporate charts and images into their presentations, for a more professional look - as well as multi-language options and new modules such as Aveva Design Reuse, developed to make the transfer of ship’s data between projects a


Laser-enhanced retrofits


Laser scanning and 3D modelling may save time for ship owners when it comes to retrofitting ballast water treatment systems across applicable vessels in their fleets.


Te entry into force of the International Maritime Organization’s (IMO) International Convention for the Control and Management of Ships’ Ballast Water is set to reduce the transfer of alien organisms between international locations – and could lead to a mad scramble, as ship and boat owners race to retrofit adequate ballast water treatment (BWT) systems aboard their vessels. According to class society Lloyd’s Register, at least 7000


28


different species are transported across the globe in ballast tanks every day, and the IMO’s guidelines – namely that each tonne of ballast water should contain less than 10 living organisms larger than 50 microns (μm), and that each tonne must contain less than 10 such organisms of between 10-50μm per millilitre of ballast water – are set to lead to significant demand for approved BWT systems, to cut this number significantly.


Technically, the convention will come


into force 12 months aſter 30 flag states, representing 35% of the world’s tonnage, have ratified. At time of going to press, the number of states stood at 31, although this did not account for 35% of global tonnage. Needless to say, it will just take one large flag state, or two medium-sized flags, to sign up to set the process in motion. Of course, installing a brand new BWT system, as part of a vessel retrofit, is far

more seamless process, and Aveva Surface Manager, enabling users to transfer surfaces to and from external systems. Aveva Space Management fulfils the


aforementioned demand for the automatic subdivision of the ship into defined spaces. For instance, when finalising general arrangement-based drawings, users can generate fire insulation plans as an automatic output, as well as calculate, at an early stage of the project, how much said insulation materials will cost. Similarly, users can work out the heat and


power outputs of electronic items installed in each onboard space or room, and determine weights and centres of gravity for objects within each separate ship / boat section, as well as taking into account factors such as heat dissipation. Should multiple subcontractors be involved in the project, they will be able to access their respective onboard spaces, via the soſtware’s Common Reference Model. Neuvéglise claims that Aveva 12.1 also


speeds up the entire process, recorded in trials as being up to 50% faster for the user compared to some conventional systems, and 10% faster than the group’s previously used Tribon architecture. SBI
