ABSTRACT
Ports are facing to deal both with economical aspects of their investments as well as environmental aspects. The huge investments in port infrastructures like quay walls, jetties, slopes, reclamation all these activities have their impact. For ports it is essential like other business centres that they are or will be sustainable. It is therefore required to adopt a life cycle approach for their investments. This paper discusses the old fashioned method of port investment and proposes and discusses an alternative method to take into account the life cycle aspects such as material costs, construction costs and demolition cost related to the environmental aspects such as transport of material, reuse of material, production of material. Conclusions and recommendations are: i) build a structure based on an standard uniform design and do not let customer needs influence the design, ii) try to predict repair just in time, iii) adjustments to the quay are expensive in the first 20 years, and iv) demolition costs do not influence the business case.
