And then, six aspects of sheet-piled wharf construction are discussed： sheet pile, anchorage structure, guiding girder, anchor rod, backfilling behind sheet pile wall, superstructure of sheet-piled wharf etc. The construction of sheet pile involves piling on the land or piling？on？the sea, piling methods, piling patterns, guide frame, embedding sheet piles etc.展开更多

This paper initially introduces risk assessment approaches within the emerging role of ports Thereafter, it qualitatively assesses their potential for ports by discussing issues challenging every safety and security approach within the maritime industry such as proactiveness, organization, transparency, cost-effectiveness and, when possible, calibration to specific experiences. Moreover, an empirical study was conducted in order to provide evidence for formal risk assessment for safety and security in the main Greek port container terminals of Piraeus and Thessaloniki. The empirical research is based on in-depth semi-structured interviews with the administrations of container terminals. The results include important findings, regarding the likelihood of appearance of certain risks and their perceived severity in Greek container terminals. The collected answers and their analysis are also important for confirming the suggested theoretical formal risk assessment framework for ports.展开更多
