SUMMARY
Crash in high speed vessels has more in common with automotive accidents that those of slower larger vessels. A computer simulation model was developed to predict the structural damage and the injuries to ship crew and passengers, in the event of a 40knot crash of the CLF with a harbour structure. The work involved reviewing and implementing established crash modelling and occupant simulation methodologies from the automotive sector. In terms of an injury prediction model, standing occupant models were used to simulated injuries and trauma at selected positions in the ship. The results will be used to inform a GA development process to improve evacuation and propose innovative active safety technology, to mitigate the risk of fatalities.
1. INTRODUCTION
The EU Trans-European network “motorways of the sea” (MoS) concept aims at introducing new intermodal maritime -based logistics chains in Europe, which should bring about a structural change in transport organisation. These chains will be more sustainable, and should be commercially more efficient, than road-only transport. Motorways of the sea will thus improve access to markets throughout Europe, and bring relief to the over- stretched European road system [1]. Informed by the MoS proposal EBDIG-IRC have developed the CLF (Cruise-Logistics-Ferry) concept [2]. The CLF is a high speed vessel to compete with road transport and air transport, supported by specialised infrastructure to optimise the vessel loading and unloading process for cars and HGVs. The
vessel design combines the
following functions: high speed ferry as an alternative to HGV road transport; passenger ferry as a alternative to flights; luxury cruising cabins. It
is based on a 120m
trimaran platform designed to operate at 40 knots as a coastal cruiser in the Mediterranean, connecting the coast of Spain, France and Italy. The structural design and non- linear crash analysis of a new CLF design are presented in this paper.
The CLF concept is an engagement in Design-Driven Innovation (DDI), with the objective of changing the design meaning of what a multi- purpose commercial vessel can be. It is a new market sector for the commercial marine industry. The key driver is sustainable luxury, as the vessel is multifunctional, providing a high speed alternative to less sustainable modes of transport. This addresses the growing European definition of green luxury and could create a new market sector between cruise ships and high end passenger ferries, reducing motorway traffic and hence logistics carbon footprint.
1.1 DESIGN-DRIVEN INNOVATION
The process of Design-Driven Innovation is an exploratory research project, which aims to create an
entirely new market sector for a given product through changing the
design meaning the user has for the
product. It occurs before product development and is not the fast creative brainstorming sessions that are typical of concept generation but a design investigation similar to technological research [3]. In essence, it is the development of a design scenario through engaging with a range
of interpreters in technology or and cultural
production. Knowledge is generated from immersion with the design discourse of the interpreter's groups. The process can be structured
unstructured and is
dependent upon the nature of the relationship of the client with the interpreters. In this project there was unstructured design discourse between researchers within the EBDIG-IRC group at Coventry University and DITEN at Genoa University. It also included input from their industry networks. This resulted in the design scenario of the design brief, which was executed by a group of Coventry University 3rd year Boat Design student as a professional internship project within the EBDIG-IRC. It involved implementing the emotional design framework developed for superyacht design [4]. The key issues of the design proposal were:
Need for a high speed platform to compete with truck motorway delivery times Determine the key truck logistics routes around the Mediterranean that could be replaced by MOS and identify the volume.
Identify the potential to replace air freight in the coastal Mediterranean areas.
Identify the potential to replace air travel in costal Mediterranean.
Building on the ultra-luxury cruise market with the USP of low carbon as vessel has logistics as a primary role with speeds that are closer to road transport. Boote et al [5] identified the motorways of the sea potential market for a fast ferry trimaran in the medium and small size segment. Specifying a medium size fast ferries, carrying up to about 800 passenger and 250 cars, with a displacement of 800-2000 tons and length 70-120m, operating at a service speed 35-55 knots. The trimaran platform was recommended as it has better seakeeping
