Green ammonia FPSO could possibly be constructed both via conversion of an present VLCC or as a devoted newbuild vessel.
With inexperienced ammonia eyed as key to the power transition, DNV has granted its approval to an modern floating answer. An industrial scale idea, being developed by Netherland-based SwitchH2 B.V. and Norway-based BW Offshore, facilities on an NH3 FPSO powered primarily from a wind farm. It will produce hydrogen by electrolysis of seawater and nitrogen via using an air separation unit, combining these in an ammonia synthesis unit.
The FPSO could possibly be constructed both via conversion of an present Very Large Crude Carrier (VLCC) or as a devoted newbuild vessel.
The ammonia fuel produced by the unit will probably be condensed, and the liquid ammonia will probably be saved within the hull with a purpose to be subsequently offloaded to an ammonia service. The NH3 FPSO will probably be completely moored however may be relocated as needed via deliberate disconnect. The offloading of the inexperienced ammonia will probably be finished via a floating hose, reeled from the aft ship to the shuttle ammonia service midship manifold.
The AiP covers all points of the built-in vessel idea together with structural integrity, mooring, ammonia manufacturing, ammonia storage and cargo dealing with,” says Conn Fagan.” DNV’s vp, enterprise improvement for floating manufacturing. “We are pleased to see such developments both with regard to use of renewable energy and as a contribution to emission reduction across many potential applications in different industry sectors.”
With the granting of the AIP, the inexperienced ammonia venture is now able to enter the essential design section.
“We are delighted we have been awarded the AiP from DNV for our concept and we look forward to working with DNV in the next stages of the project,” says Bob Rietveldt, a member of the administration board at SwitcH2.
“At BW Offshore, we leverage our offshore experience to support and expedite the energy transition by engineering next-generation floating production solutions. Achieving this AiP is an important milestone and an encouraging step towards a cleaner energy mix,” says Fredrik Savio, SVP venture improvement at BW Offshore.
