Nauticus Machinery v14.4.0 (August 2021) Nauticus Machinery August 2021-release contains the following modules (all v14.4.0): · Nauticus Shaft Alignment with whirling and axial vibration extension · Nauticus Torsional Vibration with ice impacting simulation extension · Nauticus Gear Rating with ice-class extension · Nauticus Shaft Fatigue with ice-class extension · Nauticus Gear Faceload · Nauticus Crankshaft Fatigue · Nauticus Propeller Blade · Nauticus Controllable Pitch Mechanism The following main improvements are included in the release (see Release Note for more details - download link below): Nauticus Torsional Vibration o Calculate power margin at barred speed range (BSR) for steady state calculation according to DNV rule. o Find barred speed range automatically for steady state calculation. o Shows damping torque, elastic torque and resultant torque separately and combined for all types of coupling. o Supports the non-linear coupling in the ice impacting simulation calculation. o Improve the display of chart result. - Nauticus Shaft Alignment o Provide the function to calculate the tail shaft bearing clearance. o Provide option to model the aft stern tube bearing with effective length. - Nauticus Gear Rating o Support ISO6336 2019 Edition. o Introduce rule version control for the ISO 6336 standard. - Nauticus Propeller Blade o Update the blade strength calculation with stress from CFD&FEM according to DNV rule 2021-07 edition. o Introduce rule version control. o Update the simplified criterion for propeller blade fatigue calculation of Baltic ice class according to the DNV Rule Part 6 Chapter 6 Cold climate 2021-07 edition. - Nauticus Crankshaft Fatigue o Provide option to use the tested fatigue strengths for the criteria evaluation. o Update the oil bore angle drawing. - Nauticus Shaft Fatigue, Nauticus Gear Faceload and Nauticus Controllable Pitch Mechanism. o Minor improvements and known issues are fixed - Nauticus Machinery Workflow Manager o Improve the storage capacity and loading performance for the portable local database . The installation consists of a Client installer and a Server installer. Client installer: When the client is installed, a local database (using SQLite) will also be installed in the local computer. Thus users can utilize the software by the client installation only. Server installer: Use the server installer to install the SQL database on a server. This is a more powerful database and can be shared by several clients.
