1 INTRODUCTION

The purpose of this document is to inform the users about new features and changes in the Nauticus

Machinery October 2014 release (v12.0). This release is fully backward compatible with the December

2013 release (v11.5).

Nauticus Machinery October 2014 release (v12.0) is a major release and a lot of enhancements and

changes has been done. The main features can be summarized as:

- General

o A portable local database is introduced by using SQLite and user can use either this light

database or use previous server database (use Microsoft SQL Server Express). Refer to

Nauticus Machinery Workflow Manager user manual for more information.

o The installer is improved and it is split into Client and Server. The older users or users

who want only use SQLite as database can only install Client. Read the Installation Guide

for more information

o Direct-X is removed and graphic model like the Shaft Alignment view model is updated

by new method. Thus the installation supports windows 8, 64 bit OS.

- Nauticus Controllable Pitch Mechanism

o It is a new calculation tool which is developed in close cooperation with DNV GL Approval

Center and the calculation methodologies are based on DNV GL’s long term experience

and knowledge from damage cases. The software calculates the static and fatigue

strength capacity for the components in pitch control mechanism and propeller hub. Both

main class and ice class requirements are implemented. As these methodologies are still

in the process of being updated and not officially published in DNV GL rule, we consider

this release as a beta version.

- Nauticus Shaft Alignment

o The calculation efficiency is highly improved

o The method to consider the shear deformation in FEA-solver is improved

o The report generator and result viewer are renewed to be more user friendly

o The result of Input data – all data is revised to show complete information of all

conditions

o The buoyancy correction setting is improved and user is able to specify the water/oil

density

o Jack stiffness is considered in the jacking calculation

o New chart result Bearing loads seen from aftward is introduced to show the bearing

resultant force

- Nauticus Torsional Vibration

o Implement the steady state approach to handle the ice impacting on the propeller

Notice: The steady state approach to handle the ice impacting is not officially recognized in

the DNV rules. As far as this release it is unknown if DNV GL will accept this method in

future common rule sets. Consequently, the time domain analysis is the only approach that

is currently accepted by DNV Class. Until the release of the common DNV GL rule set, it is

not advisable to use the steady-state approach in the final design of ice class projects

| RELEASE NOTE | Nauticus Machinery version 12.0 Page 3

under DNV Class.

o Introduce the partial firing condition for engine excitation to simulate the gas engine’s or

dual fuel engine’s imbalanced combustion.

o Implement the electric motor and generator-set excitation

- Nauticus Crankshaft Fatigue

o Support digitized cylinder pressure curves

- Nauticus Shaft Fatigue, Nauticus Propeller Blade and Nauticus Gear Rating&Faceload

o Small improvement and known issue fixed

Your feedback is important to us and the above improvements are a result of such. We thank you for your

continuous support to Nauticus Machinery. If you have any suggestions, questions or problems please

send an email to: [email protected] or contact one of our local DNV GL Software offices.

2 HIGHLIGHT OF NEW RELEASE

There are five important issues in the 12.0 release.

- A new portable local database (SQLite) is introduced. This database can be copied and reused in

different users. User can sync the projects and calculations between this local database and the

server database (Microsoft SQL Server Express). For the standalone users or users do not need

to remote a database can only install the Client installer and use this local database.

- A new calculation tool, Nauticus Controllable Pitch Mechanism, is implemented.

- The Shaft Alignment solver is improved from two points: A new methodology of considering

shear deformation is introduced to improve the calculation accuracy; the method to form the

stiffness matrix and the numerical calculation method are changed to improve the calculation

efficiency.

- The steady state approach to handle the ice impacting on the propeller is implemented in

Nauticus Torsional Vibration

- Nauticus Crankshaft Fatigue supports digitized cylinder pressure curves

3 HOW TO UPGRADE

The new version of Nauticus Machinery can be downloaded from the Customer Portal. Browse to

Customer Portal web-site: http://dnvs.force.com/ and log in with your account and find the relevant

installer.

You will need a user name and password to access the Customer Portal. To request a username and

password, enter your email address to apply. Once you have accessed our Customer Portal, you will find

the latest version of the applications by navigating to the Software Downloads tab and selecting Nauticus

from the drop down menu.

More details about the installation and upgrade process can be found in the Installation Guide on the Doc

folder on the installation CD or download.

Nauticus Machinery consists of one client and one server setup. The server setup will install Microsoft

SQL Server Express and the corresponding database schemes. The client setup will install all the

calculation tools and local portal SQLite database.

If Nauticus Machinery 8.0 or later is already installed on the computer, it will only be

necessary to run the client setup. Different versions of the client part of Nauticus Machinery

can exist on the same computer, e.g. Nauticus Machinery 11.5 and 12.0 can be run in parallel.

There is full backward compatibility with regards to models made in previous versions, but

each model file will be upgraded to the new version when it is loaded. If a model is upgraded

to for instance version 12.0, it will not be possible to open it in previous versions anymore. In

such cases it would be better to duplicate the model (copy/paste) before it is upgraded to the

latest version.

For the old users who still want to use the existing database, select Connect SQL server

during the installing client.

4 DOCUMENTATION The “Getting started” task in Nauticus Machinery provides the following information:

- Release Note

- Installation Guide

- User manuals for each tool

- Quick guides for Nauticus Shaft Alignment and Nauticus Torsional Vibration

- Multiple example models for each tool

- Scripting examples for the tools that are supporting scripting

5 MAIN NEWS

Local portable database

The SQLite database will be automatically installed to your local folder e.g.

“C:\DNVGL\Machinery\MachineryData.db” during Client installation. User can copy this database to any

other computer and reuse by define the database file path in the software Settings => Database

connection

Switching between Server database and Portable local database is also supported. User can sync the

calculations in the projects between server database and local database by the following steps:

o Go to Projects and Calculations page.

o Select one or several calculations in one projects

o Press the button Copy to Local (or Copy to Server if you connected to the local database)


o A new dialogue will show up to let you import the selected calculations to the project in the target database

Improved calculation efficiency in Nauticus Shaft Alignment

The calculation efficiency has been highly improved by improving the method of forming the stiffness

matrix and the numerical calculation method. Additionally, one more calculation option is added in the

Calculate button:

- Calculate: calculate all the results

- Calculate without RIN: calculate all the results but reaction influence number. It will save more calculation

time.

Consider the shear deformation in Nauticus Shaft Alignment

Shear deformation will play an important role for the short and wide shaft (beam). Nauticus Shaft

Alignment v12.0 has improved the way to consider the shear deformation in FEA-solver. The deformation

factor is dependent on the geometry of shaft section. Thus the calculation results (e.g. bearing load,

reaction influence number and so on) will be bit different comparing with previous versions.

The steady state approach to handle the ice impacting in Nauticus TVC

As mentioned in chapter 1 time domain analysis is the only method accepted for ice impacting torsional

vibration calculation as far as now. It is not advisable to use the steady-state approach in the final design of

ice class projects. User could use this method to do some comparison with time domain analysis or do some

initial design.

According to the ice class rules (e.g. Legacy DNV Rule Part 5 Chapter 1 Section 3 and Section 8) the

propeller ice torque excitation for shaft line dynamic analysis can be described by a sequence of blade

impacts which are of half sine shape and occur at the blade. The torque due to a single blade ice impact is

a function of the propeller rotation angle. The ice torque excitation in time-domain could like the following

chart. There is ramp up at start of impacting and ramp down at the end of impacting. One ice milling

sequence will last limited time.

In Nauticus TVC, the steady state approach to handle the ice torque considers the ice milling sequence as

steady state and the ramping up part and ramping down part are neglected. The Fourier transform method

is used to convert the excitation from time domain to the frequency domain. Then such frequency domain

excitations (harmonics) are considered in steady state torsional vibration calculation.


In the software the first four blade frequencies’ excitation orders are considered in the calculation. They

detail information of converted harmonics are shown in the text result “Ice Excitation Harmonic

Component Data”.

The IceClass notation and other necessary parameters for ice impacting calculation are specified on the

propeller property grid. These parameters are mainly used to calculate the maximum propeller ice torque

Tmax. All the ice excitation patterns share these common settings.

In the load case setting window, different ice excitation patterns can be defined for the different load

cases.


Parameter Cq and αi can be overwrite by the user.

If Tmax is constant and equal to the value at bollard condition is selected, Tmax will be constant and

independent of the rotational speed. The constant Tmax will be calculated basing on the bollard condition

rotational speed SpeedBollardCondition.

If Tmax is corrected according to the actual rotational speed is selected, n in the calculation Tmax formula

(check the following formulas to calculate Tmax according to the ice class rule) will be changing with the

actual rotational speed during the speed range.

If Tmax is corrected according to propeller law (n^2) is selected, Tmax at rotational speed n will follows the

propeller law (n^2). 𝑇max_𝑛 = 𝑇max_𝑆𝑝𝑒𝑒𝑑𝐵𝑜𝑙𝑙𝑎𝑟𝑑𝐶𝑜𝑛𝑑𝑖𝑡𝑖𝑜𝑛 ∗ (𝑛
