Nauticus Machinery Brochure

Nauticus Machineryfor marine propulsion design and analysis DNV SoftwareSafe and reliable operations at sea Bridging the gap between shaft theory and realityDNV has a strong tradition of involvement in the development of design-verification methodology and acceptance criteria for shafting systems for ship propulsion. This activity is a consequence of DNV’s main objectives: to assure safe and reliable operation at sea. DNV has done extensive research bridging the gap between shaft design theory and reality.Technical expertise makes better softwareNauticus Machinery is developed in close cooperation with DNV technical experts and with other major users with exten-sive knowledge of marine propulsion systems. The software package benefits from continuous improvements based on the latest results from R&D projects and damage experience.Hull flexibility Shaft alignment has in recent years become more of a chal-lenge due to increased power, lower shaft speeds and heavier propellers in combination with a shorter propulsion shaft. Con-sequently, these effects should be carefully considered when designing an optimal shaft line in order to avoid problems in operation.Shaft alignment challenges Proper shaft alignment analyses during the design phase help to avoid both delays in delivery and alignment problems in operation, thereby reducing expensive off-hire. DNV has expe-rience from several research projects studying the interaction between hull deflections and the shaft line. DNV has in-house multidisciplinary technical knowledge and experience and is therefore a preferred active partner for finding the underlying reason for damage caused by shaft alignment and for providing assistance in shaft design.Shaft AlignmentShaft Alignment provides efficient methods to build a shaft model and analyze bearing loads, bending moments, deflec-tions and more. It also provides customised verification results such as hydraulic jacking curves and gap/sag values in flanged connections. Whirling and axial vibration analysis is also covered.Torsional Vibration Torsional Vibration is a state-of-the art tool for analysis of steady-state vibratory levels in all kinds of marine propulsion sys-tems (diesel, electric, gas or steam powered). It contains a pow-erful mass-elastic modeller, scripting functions and advanced charting and reporting.“The Nauticus Machinery Shaft Alignment software was an easy choice for us. We have found it the most user-friendly and effective analysing tool for alignment and natural whirling on the market.” Andreas Malmkvist, Contract Management, Shaft Analysis, Kamewa Products, Rolls-Royce ABPropulsion design and analysis For fatigue, strength and vibration analysis in marine propulsion systemsShaft FatigueShaft Fatigue is a rule based calculation tool for validation of fatigue life and safety factors in steel shafts according to IACS and DNV Rules, The tool calculates the maximum stress limits for high, low and transient cycle fatigue which can be applied as acceptance criteria check in Nauticus Torsional Vibration.Gear Faceload and Gear Rating Gear Faceload evaluates the face load factor for parallel axis spur and helical gears based on the graphical method (iterative analytical method) outlined in DNV Classification Note 41.2. The face load factor takes into account the effects of the non-uniform load distribution across the gear face width on the surface stress. Nauticus Gear Rating is intended for cylindrical and bevel gears. The calculation procedures cover gear rating as limited by contact stresses, tooth root stresses and scuffing resistance.Crankshaft Fatigue Crankshaft Fatigue is a rule based calculation tool for calcula-tion of safety against fatigue failure in pin and journal fillets and in oil bores, as well as safety against slippage for semi built crankshafts. The calculations methods are according to IACS and DNV Rules.Project Manager and collaborationNauticus Machinery contains an easy-to-use Project Manager which acts as the common entry point to all the available calcu-lation tools in the package. It provides a scalable deployment model where users can install the calculation tools and database on the same physical computer, or work towards a central/re-mote database. With the Project Manager in Nauticus Machin-ery, it is easy to organise calculations, notes, spreadsheets and attachments in one common user interface. In-house spread-sheets and tools can easily be integrated in the Tool Library which provides a simple role-authentication and revision control for your calculation tools.User conferences and seminarsDNV Software offers numerous software conferences and seminars worldwide. Users and potential users can gain insight, not only in the applications we offer, but also into future trends. The conferences and seminars provide us with a unique oppor-tunity to communicate with other users, and to receive valuable feedback. Our goal is to make sure that the participants learn about efficient use of our products and develop competence. The conferences and seminars will typically include presenta-tions of new releases, case sharings, customer studies, and hands-on workshops.“The Nauticus Machinery Shaft Alignment software was an easy choice for us.
