DNV GL launches upgraded Nauticus Hull

Feb 09 2018

DNV GL has upgraded its Nauticus Hull software to provide improved support for the new DNV GL rules and IACS requirements.

The software covers DNV GL rules for classification of ships and IACS Common Structural Rules (CSR) for bulkers and tankers with capabilities ranging from simplified rule-check and scantling calculations to advanced tools for finite element structural analysis.
“We are very pleased to see Nauticus Hull V20 go live,” said Geir Dugstad, Director of Classification at DNV GL – Maritime. “With this new version, we have a very efficient rule calculation tool on the market. Nauticus Hull V20 enables increased approval efficiency, quality and superior design support, and is another big step in making the DNV GL rules the industry’s preferred standard.”
With new ship rules and IACS requirements increasing the scope of hull design, efficient rule calculation tools are essential in the design development for documentation of rule compliance, the class society said, adding that Nauticus Hull Version 20 has a new modern user interface with powerful modelling and rule check capabilities. 
The hull scantling design program - ‘Section Scantlings’ - has been completely renewed with modelling, analysis and result viewer integrated into one user environment. In addition, new functionality for prescriptive cross section calculations has been added – including bow impact, ice class, and connection area requirements. 
The new software was developed in co-operation with major shipyards and ship design companies to gain a better understanding of user requirements. This has allowed DNV GL to work with designers and approval engineers to smooth out any barriers to efficient use of the tool, DNV GL said. Over the next development cycle, the class society will continue to expand the software’s functionality and streamline work process for the different ship types. 
Nauticus Hull V20 is available now to all customers with a valid support agreement. Training courses are offered worldwide to bring users up to speed on the latest software features. 
In addition, DNV GL has increased its investment in 3D printing for the marine and offshore sectors, by establishing what it terms a ‘global additive manufacturing centre of excellence’ in Singapore. 
The new centre will serve as an incubator and test bed for research and development of additive manufacturing technology for the oil & gas, offshore and marine (O&M) sector, the class society explained.
The centre, which is supported by the Singapore Economic Development Board (EDB), will focus on developing competence including qualification, certification and training for additive manufacturing (AM), also known as 3D printing.
While AM is raising more and more interest in various industries, as the benefits of speed and cost against traditional product manufacturing become apparent, the adoption level in the O&M sector is still low due to challenges in qualification and certification. 
DNV GL will invest in competence development and will be working with local research institutes and industry partners through joint collaborations to advance the use of AM.
