Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method of assembling and installing a device for exploiting an oil-field. Said device comprises an upper structure comprising two superposed platforms provided with vertically slidable column, a lover structure comprising at least two tanks connected to the upper structure by means of support legs. Such a device allows its elements i.e. each of the platforms and the tanks to be fabricated separately and, the assembly to be performed only in floating conditions and not in a dry dook. Furthermore the fabrication can therefore take place in a yard designed for constructions of small size compared with that of the completely assembled device.
