Estruturas portuárias: distribuição de esforços na infraestrutura devidos à amarração e atracação de embarcações

Abstract

This work presents a study on the design loads due to mooring and berthing of vessels, regarding the design and analysis of port structures. A literature review was conducted, with emphasis on technical standards and codes, encompassing both national and international publications. More specifically, this study considered design recommendations of the Brazilian Standard NBR 9782/1987, the British Standard BS 6349 and the German Standard EAU 2004, in addition to the recommendations of the Permanent International Association of Navigation Congresses (PIANC 2002) and the analysis procedure proposed on the book “Port Works” by Jayme Mason (1982). The design procedures proposed by these different references regarding the computation of forces due to mooring and berthing of vessels where evaluated in this work. Later, a case study of a port’s substructure was carried on, and a comparative analysis of the results, obtained with each recommendation of the aforementioned publications, was performed. Results showed a remarkable dispersion, revealing a strong influence of the standard to be used in the design loads of port structures.
