Overview on Sandwich
This presentation will focus on the research done in the field
of laser welded metal sandwich panels from the perspective
of a shipyard. Application cases for SANDWICH panels will
be given.

Guidelines for laser welded Sandwich panels
Novel structural solutions such as metal-composite sandwich
panels are a continuous challenge for regulating bodies and
engineering offices. In the absence of specific requirements,
designers and surveyors faced difficult tasks. Today the Guidelines
provide a unified basis for design and approval. The Guidelines
specify a comprehensive set of general requirements and acceptance
criteria. The Guidelines are intended to serve as a standard
and to form the basis of DNV's official documents for more
streamlined and transparent verification process. The Guidelines
reflect the basic philosophy of rules, codes and standards
used in the marine, rail and automotive industry and are intended
to supplement these normative documents.

Practical design solutions for laser welded Sandwich panels
This presentation will deal with stiffness and strength prediction
of
laser-welded foam filled steel sandwich panels. The strength
issues
studied are focused on localised buckling and the effect of
foam
filling. Finally, an example will be shown on how this can
be used for
optimal design.

Design challenges and demand for future research
The major design issues for practical applications of steel
sandwich panels are summarised. The presentation includes
topics such as: elastic response and strength formulations,
fire safety, corrosion and joints design. The current state-of-art
is reviewed and finally future research needs are shortly
discussed.

Sandwich testing procedure (DoE)
Presentation of test planning for global bending tests of
i-core and corrugated laser welded sandwich panels. The tests
are carried under varying of load cases and boundary conditions.
On the base of very extensive tests materials are presented
the evaluation steps and the derivation of approximate equations
for calculation of panel deflection.

Overview and outlook
Coating is an increasingly important area for ship owners
and operators. The regulations being imposed in Europe on
Health and Safety and environmental control place an extra
burden on ship yards. This presentations gives an overview
of the research performed in the ECOPAINT project covering
the improvement of health and safety performance, reduction
of environmental impact, and the development of guidelines
for best practice coating processes. A software tool for the
monitoring of VOC emissions will be introduced. Finally, an
outlook to the project "Environmentally friendly coatings
for ship building and ships in operation - ECODOCK" will
be given.

Environment friendly coating processes
This presentation gives an overview of the investigations
to improve surface preparation and application technologies
for marine coatings. The different methods were evaluated
according to economy, environmental impact, health and safety
conditions and technical performance. The presentation introduces
how six different surface preparation methods were compared
through large-scale tests and target tests at test panels.
Five different application methods were compared through large-scale
tests at Jos. L. Meyer yard and at the premises of Wagner
Systems Technology Centre in Markdorf. A main focus of the
presentation will be on the technologies dry ice cleaning
and electrostatic spraying.

Production of Sandwich X-core structure
This presentation will focus on production aspects of laser
welded metal sandwich panels with respect to crashworthy structures.

Crashworthiness of the SANDWICH X-core structure
There are three tasks to be accomplished in this project.
The first task is to establish a method for taking into account
the effect of crashworthy side structures on the survivability
of ships with respect to flooding through a collision damage
hole. The second task is to design two side structures with
an exceptional crashworthiness which performs at least two
times better than conventional structures. The third task
is to introduce crashworthiness into design practice. The
work consists of both desk studies and full scale experiments.
The presentation will give an overview of the main outcomes
of these tasks.

Approval Procedure
Concept for Alternative Arrangement in Relation to SOLAS Ch
II-1, Part B-1, Reg. 25-1.3. The basic idea of the approval
procedure is to compare the critical deformation energy in
case of side collision of a strengthened double hull structural
design to that of a reference one complying with the damage
stability requirement of SOLAS Ch. II-1, Part B-1, Reg. 25-2,3,4.

The BONDSHIP project: outline, key results and future developments
In this talk the BONDSHIP project will be presented; its aims
and partnership and the approach taken in the project. Next
some of the key results and achievements will be discussed
with focus on the project guidelines. Finally future developments
regarding the guidelines and possible new applications for
adhesive bonding will be outlined.

Design and testing of adhesive joints in ship-building
Examples from the BONDSHIP mock-up Application cases for adhesive
bonding will be discussed with respect to the
design process, manufacturing and testing. The design process
has to consider a variety of requirements according to structural
loading, ageing at maritime environments, fatigue behaviour
and manufacturing.
