Control of vibration levels in propulsion systems and generator sets is essential to have machinery that operates safely and reliably.

The wrong combination of individually satisfactory components may lead to an inappropriate system. Nauticus Torsional Vibration is a software tool that analyses the torsional vibration levels in the propulsion system and identifies critical components.

The new Nauticus Torsional Vibration tool gives you the following new features:

• New graphical user interface with fast and efficient modelling options
• Component libraries
• Acceptance criteria check (IACS M68 and more)
• Advanced viewing and reporting facilities
• The software is not limited to only diesel engine plants, as it can be applied on various kinds of systems such as gas turbine or electric motor systems
• New equation solver based on LAPACK library
• No practical limitation with regards to number of masses or shafts
• Developed in close cooperation with DNV Maritime, with its know-how and experience on marine propulsion systems.

The general scope of each release includes:

• 1st release: Direct driven propulsion plants with propeller
• 2nd release: Generator sets with or without elastic couplings
• 3rd release: Single stage geared propulsion plants.
  This release will be available in January
  2006.

The application will be enhanced with analysis of multi-branched propulsion systems during 1st quarter 2006 and will gradually replace DNV’s PILOT nV5235 application.
