CHALLENGING THE
DESIGN FOR X – PERSPECTIVES…
“One”-dimensional ship design
approaches can, typically, be
described by the Design for Xconcepts - X being, for
example:
– The Design for Safety
– Design for Sustainability
– Design for Environmental
Friendliness
– Design for Reliability
– Design for Energy
Efficiency
– Design for Life Cycle or
Design for Production
– …
All vessels have a purpose!

TYPES OF MEASURES OF MERIT
The choice of a solution from many
alternatives must be made on the basis of one
or more criteria.
Traditionally, in the marine industry, the
criteria are generally based on economic
considerations and called measures of merit
Criteria based on cost (1960-1970) H. Benford
– Cost of investments (CAPEX)
– Cost of operation (OPEX)
– Cost of voyaging (VOYEX)
Criteria based on cost and income
(1970-1990) I. Buxton, S. Erichsen
– Net present value
– Annual rate of return
– The payback period
– Internal rate of return
– Project cash stream/value
– Vessel cash stream/value
Critria based on expectations (1990- …)

CASE STUDY – WHAT SOLUTION MEETS BEST THE
PRE-SET EXPECTATIONS OF THE STAKEHOLDERS
AHP-model of the Smarter, Safer, and
Greener effectiveness perspective
Importance ratios:
– Expert judgment & statistical
analysis
– Smarter: 60%
– Safer: 23%
– Greener: 17%
Target point is equal to importance
ratios
– Solution 4 is a Smarter solution
– Solution 2 is a Greener solution
– Solution 6 is a Safer solution
Solution 4 achieves higher overall score
applying the importance ratios

TURNING VISIONS INTO REALITY
Technical and operational challenges?
The ships:
Improved turnaround time
More space and capacity for payload
Better sea keeping and manoeuvring capabilities
Multipurpose capacity
Minimal repair and maintenance needs
The designs:
More simplistic and cost-effective ship designs
”Smarter” ships
“Smarter” shipbuilding
“Smarter” functionality
The operation:
Integrated transport services (door to door)
Professionalized commercial operations
More efficient ports and hinterland connections
Port facilities:
Ports with shorter entrance
New port developments and upgrades of old ones
New and alternative solutions for cargo handling and further
hinterland distribution
Are we willing to change the approach?
