O transporte marítimo é a opção menos poluente e menos custosa para o transporte de mercadorias. Com o aumento da demanda neste segmento surge o interesse por alternativas ecológicas e economicamente mais atrativas. Como parte integrante do projeto de um terminal portuário, obras de abrigo são necessárias na grande maioria dos casos. Nesse contexto, foi resgatada a importância da pesquisa e inovação do quebra-mar flutuante. Além disso, o quebra-mar também pode promover proteção costeira, outra discussão muito atual. O quebra-mar desenvolvido e estudado nesse trabalho é uma inovação e possui vantagens dentre as concepções praticadas atualmente. O conceito ecológico de empregar garrafas PET descartadas, eliminando-as do ambiente, cria um interesse ímpar por parte dos ambientalistas. Economicamente esse quebra-mar é mais vantajoso, pois os materiais são de baixo custo e de fácil aquisição. E também pode ser construído em terra e rebocado para a posição, no corpo d'água, eliminando as dificuldades e custos de uma construção a partir de plataformas destacadas e flutuantes. Por último, ressalta-se a eficiência na redução da altura de onda, pois esta foi significativamente maior que a encontrada por pesquisadores que testaram concepções comparáveis a essa / Abstract: The growth of the Brazilian economy urges for improvement in transportation and logistics for products that move though the country. Seaways are the less pollutant and the most cost effective way to move ware. The increasing demand for this segment creates interest in more environmentally friendly and cheaper options and sheltering installations are part of a port's design. Within this scenario, the relevance of research and innovation for floating breakwater is recovered. Furthermore breakwater can as well provide coastal protection, which is an existent concern in modern time. The floating breakwater that is being discussed in this paper is an innovative and advantageous when compared to others that are in use have been designed and built. Due to the reuse of many plastic bottles and regarding the fact that they are being taken away from the waste environment, this floating breakwater creates a good impact on the ecologists. From the economic point of view it is less expensive due to the fact of the purchase of used plastic bottles to be cheap and easy. Also, the breakwater can be constructed on shore and dragged to position which eliminates the complexity and coast of building of a vessel. Its efficiency in wave height reduction goes significantly beyond the reduction ratio of other concepts that are comparable to this floating breakwater / Mestrado / Recursos Hidricos, Energeticos e Ambientais / Mestre em Engenharia Civil

This thesis describes the processing of 3D Laser measurements from Vestpynten, Svalbard to find out the erosion pattern at the site as a basis for the design of an appropriated shore protection suggestion and also to evaluate the applicability of 3D laser measurement systems in Arctic environments. 3D laser measurements would be interesting for the analysis of areas with limited  accessibility, since 3D laser measurement allows very precise recordings of the landscape/ surfaces without the need of accessing the investigation area. Based on the processed pictures and further erosion analysis the thesis suggests an erosion protection design for Vestpynten, based on geosynthetics. This was found to be necessary, since the road connecting Bjørndalen to Longyearbyen is at Vestpynten only a few meters away from the edge of the instable, eroding cliff. The suggested geosynthetic protection design is expected to be appropriate in terms of ecological and economical requirements of the site.
