[en] In the last years, offshore industry has become into one of the most innovative and profitable industries all over the world. Due to its high complexity requirements and the huge number of technologies involved, this industry is now a vast ocean where young engineers can dive in search of new knowledge and opportunities to contribute to the development of the engineering.

Some of those technologies involved in offshore industry are special portable devices designed to transport special equipment from the shore to offshore facilities. In addition, different international organizations have been developing design codes for steel structures in the last years. However, how similar are these codes? Are there significant differences between them?

A comparative analysis between five offshore design codes (API, DNV, Eurocode, ISO and Norsok) has been carried out for a portable offshore unit in this master thesis. DNV software and different codes and standards have been available to accomplish this task and try to get to a conclusion. To do this, several analysis in different scenarios were done to have a wide enough range of results and be able to do an accurate study of the situation.

Clear and solid conclusions have been got for these codes and a “pattern of behavior” has been determined for all of them. Results show that one of the codes is very conservative in it results, with differences from 40% up to 190% of it values. Furthermore, some ideas for future research in this topic have been proposed.
