Problem identification


Ferries sink too often !!!

>  How many souls are lost ?

>  What ferries are sinking ?

>  Why ferries are sinking ?


Number of fatalities

>  Source: Lawson/Weisbrod (Journal of Public Transportation, Vol. 8, No. 4, 2005)

>  Between 01/2000-05/2004:

–  4000 people lost lives

–  in 18 large-scale incidents

•  5 in Bangladesh, 3 in Somalia, 2 in Indonesia, 1 in USA and Pakistan,

remaining 6 in Africa

–  Over 75/month on average

Fleet age profile (what ferries are sinking?)


>  Typical life of a ferry:

>  North Europe/Japan (0-10y)

>  South Europe/China (10-20/25y)

>  SE Asia/Africa (> 25y)

Causes of accidents (why ferries are sinking ?)

1.  Source: Worldwide Ferry Safety Association

2.  Four most common reasons: –  Vessel quality

–  Crew training

–  Hazardous weather

–  Overcrowding


Proposed solution


SAFE and AFFORDABLE new-built ferry

Obviously contradictory, but we need to know:

>  How to design a ferry that is instrictly safe ?

>  How to ensure a newbuilding is available for selected markets ?

>  How to best satisfy multiple stakeholders:

–  Shipyard

–  Owner/operator

–  Local community

–  Natural environment


Designing safe ferry (1)


Accident cause How Designers can help ?

Vessel quality •  Simple design (shapes, layouts)

•  Easy to maintain (detail design)

Crew training •  Layout of control stations

•  Crew accomodation

Over-crowding

(leading to loss of stability)

•  Main dimensions

•  Overall layout (General Arrangement)

•  Tank location/shape

•  Hullform (‚form’ stability)

Designing safe ferry (2)


Accident cause How Designers can help ?

Rough weather •  Main dimensions (resonant motions)

•  Hullform (dynamic stability, freeboard)

•  Redundant and adequate propulsion

Collision/grounding •  Proper subdivision (bulkheads, water-on-deck)

•  Protected openings (ramps/visors, vents)

•  Robust structure (high crashworthyness)

•  Easy evacuation (obvious evacuation ways)

Designing safe ferry - summary

List above suggest that:

–  Main dimensions are critical (capacity, stability)

–  Overall layout is very important („flows”, flooding)

–  Detail layout (control stations, accomod., tanks) is important

–  Several other aspects need to be addressed (e.g. passenger

comfort, available docks etc.)


How to ensure low price ? >  Simple shape (production-friendly)

>  „Basic” but robust equipment type

>  Fuel efficiency

>  Alternative approach to regulatory compliance (avoid

overdimensioning)

>  Interior standard in line with local market expectations (basic)

>  Modular layout

–  IMC (integrated, modular, customisable) approach (midway between standard

and fully custom-made)


How to ensure finansing ? >  Investigate national goverments willingness to support:

>  Approach international financing institutions:

–  International Monetary Fund

–  World Bank

–  Asian Developent Bank

–  Asian Infrastructure Investment Bank (not yet operational)


How to ensure finansing ? >  Major shipbuilding players might be willing to support:

–  From China (CSIC, CSSC, AVIC)

–  From S. Korea (SHI, HHI, DHI)

–  From Europe (Fincantieri, Meyer)

–  From Singapore/Australia (Austal, SembCorp, Keppel)

>  Industry groups (like INTERFERRY) to encourage/coordinate/support

the efforts to ensure finansing

>  Consortium of equipment and service suppliers may be the way

forward


Ballancing stakeholders

This project will aim at utilising Competitive Optimum methodology to

ensure that various stakeholders’ interests are accounted for:

–  Shipyard ship need to be easy to built

–  Owner /Operator ship need to be cheap to buy and

operate

–  Local population travel need to be cheap and safe

–  Environment ship need to have minimum impact (in

operations and in case of accident)


Selected technical issues


Key technical objective

>  A method is needed to find best main dimensions and overall layout

>  Such method need to address at least following aspects:

–  High initial stability

–  Preventing overcrowding (shortage of deck space)

–  Damage stability compliance

–  Seaworthiness and crashworthiness

–  Smooth evacuation and quick (un)loading (i.e. proper flow of passengers

and/or cars)


Features of selected approach

>  Selected approach should combine:

–  Competitive Optimum approach (for everyones

satisfaction)

–  Genetic Algorithm (for quick multicriteria selection)

–  Proven layout development method (for funcitonal

layout generation)


Genetic algorithm in optimisation


Layout development >  „Packing” approach:

–  developed by van Oers from TU Delft

–  Currently in use by Dutch Navy

>  Functional Building Blocks approach:

–  Developed by Andrews/Pawling from UCL

–  Integrated in Paramarine software

>  Inelligent Ship Arrangements:

–  Developed by Nick/Daniels from Univ. Michigan

–  Aims at supporting ship design in US Naval Sea System Command


Conclusions


Conclusions

1.  Problem is huge and needs solving

2.  Both technical and commercial aspects need addressing

3.  Best technical solutions need to be modified and applied

4.  Operational issues need to be better understood

5.  Various financial analysis are needed

6.  Industry-wide consortium is needed to effectively solve the

problem
