Decommissioning subsea infrastructure

Abstract

Decommissioning subsea infrastructure Abstract A method of dewatering an elongate subsea structure comprises directing a flow of dewatering fluid within the structure to a venturi formation. The flow of dewatering fluid 5 is accelerated through the venturi formation to generate a region of low pressure within the structure. Water within the structure is drained towards a drainage outlet positioned within the region of low pressure, thus expelling the water from the structure through the drainage outlet.
