Master's thesis in Offshore technology : subsea technology Energy is one of the basic requirements of sustainable development of civilizations. Mankind is moving further to harsher environments, e.g. marine and arctic environments, to sustain energy production. Technology evolution is continuously opening new frontiers, potentials and of course more challenges to overcome. Alike onshore operations, offshore developments require a certain safety level to be maintained. A safety level that limits the risks related to health, environment and assets. One basic requirement for achieving that safety level may be simplified as: understanding the environment actions caused by waves, winds and currents, and building marine structures that can handle the worst conditions.
