Risk Awareness – Key to a Sustainable Design Approach for Breakwater Armouring
In prosperous periods people tend to overestimate their capabilities and to accept significant risks. This is a widespread tendency, which led to the financial crisis in 2008. It can be seen back also in the variation in time of investments for flood protection schemes and affects last but not least the designing of breakwaters. A number of major breakwater damages occurred in the late 1970th and early 1980th (a.o. Sines, 1978; Arzew, 1980; Tripoli, 1981). In the period thereafter designers applied larger safety margins. However after more than 25 years without any spectacular failure of a major breakwater; often we see that many of the intuitively applied safety margins are disappearing. This tendency is supported by the new role of consulting engineers in EPC contracts and PPP's. Designers are working more closely with contractors; there is more focus on efficiency. This results in breakwater designs that are close to or right on the edge.
