Wärtsilä Offering Onboard CCS Feasibility Studies

Wärtsilä is now offering carbon capture and storage (CCS) feasibility studies to shipowners and operators. Studies have already been conducted on a range of vessel types including ro-ro and ro-pax vessels, a drill ship, a container vessel and a gas carrier.

The process takes four to six months of study and design work. Wärtsilä Exhaust Treatment’s experts are involved in ship design at an early stage to conduct engineering work to understand how CCS can be smoothly integrated once the technology is launched to market.

Wärtsilä is conducting the feasibility studies across both newbuild and existing vessels. Retrofit CCS installations will be significantly smoothed by the presence of a scrubber onboard. Wärtsilä Exhaust Treatment is already offering CCS-Ready scrubbers to the market, which are integrated onboard in a way that enables a CCS system to be added easily in the future once the technology is commercialised.

Once completed, the CCS feasibility study work enables Wärtsilä to provide customers with a fully rounded commercial offer that can be shared with shipyards to get an exact quote for installation. During the feasibility studies, Wärtsilä’s experts closely examine the existing naval architecture of the ship and work to understand how the power, space and exhaust demands of CCS can be accommodated onboard. Owners will receive a qualified analysis of the costs of CCS integration, and a clear list of considerations on how a potential retrofit would be conducted in the least intrusive way.

Conducting the studies today enables Wärtsilä to bring forward the early stages of CCS integration and, in doing so, lower the barrier to entry once the technology is commercialised in the near future. The studies also serve to educate customers on the upsides and particular considerations associated with installing CCS onboard their vessels. Finally, as the studies will run in parallel with the implementation of new environmental regulations for shipping, owners who conduct them today will be ‘ahead of the curve’ versus their peers.

When a customer opts for a Wärtsilä CCS-Ready scrubber, the company takes measures during the scrubber installation process to ensure adequate space for the future installation of CCS system. CCS-Ready scrubbers are also designed to enable smooth integration with a Particulate Matter filter.

Wärtsilä’s CCS technology is already achieving a 70% capture rate.
