Unloading system for direct CO₂ injection

Nemo Maritime AS has developed a ship concept for transport of CO₂, equipped to be able to inject CO₂ directly from the ship into the reservoir for permanent storage. Through the CLIMIT program, support has been granted to develop a concept for connecting ships to the injection wells, in other words an unloading system for CO₂. The solutions will cover both shallow and deep water and will be suitable for ship solutions in all waters where storage at sea is planned.

The project will develop connection solutions for direct injection of CO₂ from ship to well, based on Nemo’s concept. This includes unloading hoses, flexible risers, control cables and an anchoring system for connection to the well frame. The delivery will also describe the operational aspects of using the system. The goal is for the project to develop a complete unloading concept from vessel to well as a basis for further design and fabrication of a concrete facility as part of NEMO’s ship concept for the transport and storage of CO₂.

This project will develop technological solutions for efficient CO₂ transport and injection for the storage of CO₂ and thereby promote the competitiveness of Norwegian companies within CCS and contribute to this being developed as a commercially profitable industry both on the Norwegian continental shelf and internationally.

The project group consists of Nemo Maritime (Project responsible) OneSubsea (unloading system and connection solutions), Brevik Engineering (ship design) OMV Norge (AS) (subsea equipment and well design) and TotalEnergies (technical advisor and financial contributor).
