Abstract

Subsea chemical storage and injection system is an innovative all-electric technology that moves the chemical units from the topside to the mudline, close to wells. The objective is to replace the umbilical tubing with a power and communication link between the new chemical units located on the seabed and the topside facility. Saipem completed a unique industrialisation programme for an innovative solution. The system includes storage units, pumping system, valves electric actuator, flow metering equipment and control system equipment. Two different double barriers technologies that have been qualified for storage. The first solution uses a deformable bladder as the primary barrier while the second solution replaces the primary solid barrier with a liquid layer forming a liquid stacking tower. The paper will introduce the elements of technological novelty of the equipment and will describe the methodology, challenges, and main results of the programme. Finally, an overview of potential applications will be presented to convey the potential of this technology.
