Current and Future Developments in Ship Stability 
Regulations
by Pekka Ruponen and Markus Tompuri, NAPA

Recent changes and updates in the IMO regulations for intact and 
damage ship stability are reviewed. Main emphasis is on 
the SOLAS 2020 revision, and how these changes are handled 
in NAPA. In addition, the current status and schedule for 
the Second Generation Intact Stability Criteria development 
are presented.

Etteplan Speeds Up Early Design by Customizing 
NAPA Designer with C# Scripts
by Antti Pösö, Etteplan

As the change is the only constant in early design phases, 
designers need to be able make rapid changes to the model. This 
presentation is focusing how developing inhouse tools with C# can 
help to speed up modelling and to manage keeping the model 
up-to-date.

14:10 - 14:15 Short break
14:15 - 15:15

Two simultaneous general presentation streams:
NAPA Naval Architecture and NAPA Steel.

NAPA Naval Architecture Stream

Introduction to Improvements of Container Ship Design 
Manager Application
by Ho-Young Jeong, DSME

This presentation demonstrates how DSME has improved their 
Container Ship Design Manager application by minimizing user 
input and implementing input value checks by visualization. 
With these improvements, the container ship design can be 
simpler and more intuitive.

Harnessing Operational Data for Ship Design
by Teemu Manderbacka, NAPA

Assessment of requirements for installed engine power 
accounting for sea margin, as well as, wave loads on hull 
structure and seakeeping characteristics are dependent of 
the operational profile of the ship. The AIS data enhanced with 
the weather data can be utilized to help designing a ship for 
a better fit for future operational conditions. NAPA Fleet Intelligence 
can estimate the required power and fuel consumption of ships 
in operation based on the AIS and weather data without a need of 
onboard installation.

Introduction to the Tandem Method of Construction and 
How to Use NAPA for Applying the Method
by Bongjun Kim, Hyundai Heavy Industries

Hyundai Heavy Industries use often the tandem method of 
construction. It is a method to construct a part of another vessel, 
called as a tandem block, together with a vessel in a construction 
dock, by utilizing remained space.

The main advantage of this construction method is to maximize 
the turnover of the construction dock. When comparing the length of 
a tandem block to the overall length of a vessel under construction, 
the length ratio is generally around 30~50%.

To apply this construction method, the floating or non-floating 
condition of a tandem block has to be estimated and modified to 
have an even trim when a vessel with a tandem block is launched.

HHI would like to introduce the use NAPA for the tandem method of 
construction and their unusual cases.

NAPA Steel Stream

Advanced Structure Design Method with NAPA
by Hyundai Heavy Industries

Finite element (FE) modeling is one of the most time consuming
tasks in structural design procedure. Thus, Hyundai Heavy 
Industries adopted the auto-generation of FE model by using
NAPA Designer and NAPA Manager Application.

Notable examples of auto-generated FE model are an FE model of
an LNG carrier for the LR aft scarphing analysis, a very fine mesh
model of ore carrier (VLOC) and a re-gas module of an LNG Floating
 Storage Regasification Unit (FSRU).

Advanced FE modeling method using auto-meshing of NAPA is
more effective in the cases when the relative geometric
information has been provided or the modeling needs to be
implemented for accurate and complicated geometry. Further
application of auto-meshing will significantly reduce the time
spent for FE modeling.

NAPA Drafting to Produce Drawings from NAPA Steel Model
by Mika Jaatinen and Antti Kujala, NAPA

Frustrated creating classification drawings line by line? Generate 
sections, elevations and plan drawings directly from NAPA Steel 
model by using NAPA Drafting. Annotate drawings with smart 
annotation tools. View changes from NAPA Steel model 
interactively and update them to the drawings with just a few 
mouse clicks.

A general overview of the functionality and the recent new features, 
including styles, local edits management, editable cropping etc.

15:15 -15:45 Coffee break
15:45 - 17:00

New Reporting Tools in NAPA
by Lauri Glad and Marius Palade, NAPA

We are developing new user friendly reporting tools in NAPA. 
In this presentation we will give a brief overview of the reporting 
concepts and workflow, as well as, introduce the new tools currently 
under development. These developments include for example
the enhanced document description language (a.k.a documentation 
macros) with graphical user interface, faster document generator, 
"what you see is what you get" type of preview system as well as 
a Word-like editor for finalizing generated documents.

NAPA ServerDB
by Sherry Ummen, NAPA

This presentation will highlight the benefits of NAPA
ServerDB database solution with a real time demonstration
on how the solution works together with NAPA Designer.

Direct Interface from NAPA Steel to AVEVA
by Prostep and NAPA

Presentation will highlight the ongoing development project with
NAPA and Prostep for developing the next generation direct interface
from NAPA Steel to Aveva Hull. It will show and demonstrate
the benefits of using APIs of NAPA and Aveva combined with
Prostep specific technology solutions.

Design Loop for a Modern Submarine

by Francesco Oneto, NAPA

Submarine Design involves the usage of multiple NAPA task 
interacting in unconventional integrated way. New dedicated 
tools have been developed to help designers in handling the most 
common submarine design problems. NAPA Steel model has been 
used to both increase buoyant volume accuracy and direct strength 
calculation via finite element analysis (FEA).

DAY 3      

Meetings at NAPA Office - to be booked in advance.

Workshops

WS N1: Damage Stability Calculations

The focus in this workshop is on new development and possibilities in damage stability calculations using NAPA. For example, what are the available alternatives in PROB Manager for the calculation. The workshop will also provide some typical answers for the frequently asked questions.

WS N2: NAPA Designer Aided Stability Calculations

NAPA Designer has been a powerful tool for geometry modeling. Now it contains also some additional tools which are very useful for stability calculations. The workshop introduces different possibilities to use NAPA Designer for model verification, definitions and visualization, in order to speed up the stability calculations.

WS N3: Hull Form Optimization

This workshop introduces a NAPA tool set for design variation and optimization, complemented by external CFD. The main goal of the workshop is to present the general principles of setting up such an optimization tool in NAPA. An example of optimizing the main engine arrangement with NMRI CFD interface is demonstrated. The workshop is jointly hosted by NMRI, Sanoyas and NAPA.

WS N4: C# Scripting in NAPA

The workshop introduces the new C# scripting, in order to build custom tools to speed up the definitions and visualization in NAPA Designer.

WS N5: NAPA Basic and VSCode

With even more features available in our new VS Code Macro editor, the development and debugging of NAPA Basic macros is more efficient than ever. And with improvements in our macro execution engine and performance-profiling tools, you can make those macros run faster than ever.

WS S1: Concurrent Concept Design

This workshop will present how concept design can be done utilizing the latest tools in NAPA Designer in a multi-user environment. The workshop will consider both naval architecture and structural design point of view, focusing on cruise vessel design.

WS S2: Structure Modelling and Information Sharing

Learn to use structural modelling tools in NAPA Designer efficiently and get familiar with the available interfaces. This workshop introduces the new features and gives a few tips and tricks on how to boost your daily work. In addition, different options to share and export 3D model data are presented using some examples.

WS S3: New NAPA FEM

This workshop will demonstrate new NAPA FEM meshing capabilities included in NAPA Designer. It will show improved meshing speed, high quality graphics, interactive meshing tools and advanced update capabilities.
