Method for manufacture, assembly and continuous construction of pipe sections in a spoolbase with gradual movement

A process for continuous manufacturing, assembling and constructing with progressive displacement of pipe sections in a spoolbase, the process comprising the following steps:

• manufacturing of pipe strings in a first production line upon welding of several pipe sections;
• displacement of the string through a first roller line extending from a final portion of the first production line transporting the string from the first production line to a central area of storage of pipes disposed under the lifting ports, the first roller line disposed in part of its travel under the lifting ports;
• lifting of pipe from the first driving roller line disposed under the lifting ports to a central area of storage of pipes through the lifting systema that comprises several fixed ports equipped with electrical rolling bridges operating in synchronism for lifting the string from the first driving roller line and disposing said string in the central area of pipe storage;
• lifting of the string from the central area of storage of pipes to a second driving roller line disposed under the lifting ports, parallel to the central area of storage of pipes and opposed to the first driving roller line for transporting the string;
• displacement of said string disposed in the second driving roller line for transporting pipes, the string being displaced towards a second secondary fireline for welding the string by one of the ends thereof with other strings already disposed in the fireline or to be disposed, and after said welding, in a concomitant way, it is performed the checking of integrity of welding, of the site joint lining and the strings themselves, said displacement occurring towards the embarkation point of the coiled section disposed in the vessel, said continuous and uninterrupted displacement being directed to a storage loop of maximum total capacity between 4.0 and 7.0 kilometers;
• not limited only to these lengths;
• and
• storage of conduct lines in a storage loop.
