To achieve a good distribution in the machine room began with the single-line design of all on-board systems. With this information it was possible to visualize the quantity of pipes and diameters that should reach the machine room systems. Once all the elements have been raised and numbered, several options have been analyzed in 3D, thinking about the possibility of construction and its future maintenance. After 2 months of work a distribution of the pipes and the systems that could work and that would be the best option of the possible was obtained. With this information in 3D we started to make 2D constructive plans. Then the shipyard with these planes was able to build and test all the systems.
