On the last decades the research of design solutions for wind energy generation systems have been growing and former barriers such as the sea have been broken. Design alternatives such as offshore wind turbines that until the end of last century were not known, today prov...

The offshore oil and gas industry has been confronted with the issue of armor wire lateral instability in unbonded flexible pipes for over two decades. The objective of the present thesis is by theoretical as well as experimental means to investigate the underlying mechanism o...

Estuarine systems are dynamic environments that are under constant anthropic influence. The uses of its margins are potential polluters when in disagreement with quality standards. The climatic, hydro biological and geographical conditions make the Paraíba do Norte river estuary and the Nort...

This work presents a qualitative and quantitative approach to introduce human factors aspects in the reliability and risk assessment of offshore rig operations. The qualitative part covers the task analysis and searching for potential causes of failures based on a cognitive framework. I...

Since the added resistance in waves is associated with ocean navigation, it has a great economic, environmental and strategic importance. Hulls are usually designed according to resistance data in calm seas and therefore, they lose efficiency when encounter adverse environmental conditions. ...
