Evaluation and Optimization of the Life Cycle in Maritime Works

Abstract

The 2030 Agenda and the Sustainable Development Goals are a necessity. A large number of public actions and activities in many countries go in this direction. Various indicators are used to quantitatively assess the impacts, all of which are included within product life cycle assessment. It is essential to study and assess infrastructure, as it is an important factor in emissions, as well as environmental and sustainable construction. In maritime works, the aggressiveness of seawater is an important factor that reduces the life of reinforced concrete structures, and it is necessary to search for solutions that reduce or eliminate maintenance. In this research paper, the aim is to quantitatively verify that the composite materials are viable from an environmental and resistant point of view. Concrete caissons and/or breakwater crowns for vertical breakwaters were constructed as the fundamental elements, calculating the life cycle in comparison with several contrasting examples. The first is the case of a conventional breakwater crown, built in Escombreras, southeast Spain, at the Mediterranean Sea, later simulating the impact with one reinforced with fiberglass bars. The results are encouraging and call for additional measures to further reduce maritime infrastructure indicators with much less polluting, more durable, and more sustainable solutions.
