The Selection, Installation, and Operation of a Modern Chemical Based Technology for the DISSUB CO ₂ Removal System in Royal Navy Submarines

Having identified a deficiency in the Royal Navy's present DIStressed SUBmarine (DISSUB) Carbon Dioxide (CO₂) removal system the Marine Environment Sustainability and Habitability (MESH) IPT has run a project to assess a number of candidate technologies for use as a replacement system. Three technologies were examined initially, and a competitive procurement activity has been completed. From this a CO₂ removal system was selected for installation and operation in current and future classes of RN Submarines. This paper reports the results of this procurement activity.
