Design for Structural Safety under Extreme Loads

Objective



Objectives and content
The future of European shipyards depends on their ability
to produce new generation ships at competitive costs.
With ever increasing traffic density, safety is
increasingly becoming key for competitiveness. DEXTREMEL
is submitted to respond to the industrial need for design
methods to ensure structural safety and subsequently
passenger safety of ships in adverse environments.
The prevention of accidents as well as the management of
accidents if they occur is considered a key issue in the
future development of safe ships. To meet these
requirements, the master plan of the Maritime Industry
Forum (MIF) identified "design for safety" and
"implementation of a risk assessment process in ship
design" as research needs. In particular, the need for
methods to assess "damage robust designs" was identified.
The safety of RoRo ferries was also identified as key
research area by the Maritime Systems of the Future task
force. DEXTREMEL will provide methods to predict the
residual structural strength of damaged RoRo ferries in
extreme conditions.
Based on the simulation of a ship's behaviour under
realistic operating conditions, these methods aim at the
rapid evaluation of new concepts and configurations. The
influence of systematic design parameter variation on the
structural integrity under extreme loads will be
investigated and safe structural designs will be
identified. The results of DEXTREMEL will enable the
quantification of risks associated with (total) loss of
structural integrity due to extreme and / or accidental
loads, such as collision and grounding loads, wave loads
acting on bow doors, and loads on deck structures caused
by green water shipping. In addition, the formulation of
prenormative guidelines will contribute to new rules
concerning RoRo passenger ferry safety in extreme
conditions.//ORLhttp://research.germanlloyd.de/Projects/DEXTREMEL/index.html
