Influência do atrito das defensas no comportamento de um navio amarrado para diferentes níveis de pré-tensão nos traveses

Abstract

Nesta comunicação analisa-se a influência do coeficiente de atrito na interface do casco do navio com as defensas, no comportamento de um navio petroleiro amarrado, para duas condições de pré-tensão nos cabos de amarração. A análise é efectuada com base nos resultados de testes em modelo físico do comportamento de um navio amarrado no Posto "A" do Terminal de Petroleiros do Porto de Leixões. Esses testes foram realizados com dois modelos físicos construídos à escala geométrica 1/100. O primeiro corresponde a uma reprodução simplificada do Posto "A" e área envolvente, com o modelo do navio a ser ensaiado, exclusivamente, para ondas de vante. O segundo procura reproduzir as características do protótipo com maior rigor, e inclui o quebramar Norte (ou exterior), o molhe Sul, o antigo quebramar Norte (estrutura centenária), e uma extensão significativa da praia de Matosinhos.
