System for drilling and producing petroleum products from a shaft on the sea bed, comprising a floating structure (2) with at least one opening and a support structure (3), and several vertical pipes bringing the products from the shaft to the floating structure. These pipes each have a float on at least part of their upper end near the floating structure. The system has at least one means (12, 13, 17) allowing the distance between the different pipes to be maintained (10) whilst allowing each pipe to slide in a direction parallel to its longitudinal axis.
