WESP – cutting 95 % of particle mass
In 2024, Solvang completed the installation of wet electrostatic precipitators (WESPs) on five vessels; Clipper Eris, Clipper Eirene, Clipper Enyo, Clipper Eos, and Clipper Wilma.
After installing WESP filters on Clipper Eris, Clipper Eirene, Clipper Enyo, Clipper Eos, and Clipper Wilma, particle emissions from Solvang's fleet has been drastically reduced.
«In spite of some initial adjustment needs for the WESP to be able to tackle high sea conditions, as well as some challenges in processing the particle sludge and flush water, we are very satisfied with the concept,» says Mr. Tor Øyvind Ask, fleet director of Solvang.
The WESP technology is manufactured by Wärtsilä and it plays an important role in pre-treating the exhaust stream for onboard carbon capture and storage (OCCS), which is already installed on Clipper Eris. The setup provides enough technical data to prove for operation very soon.
«I expect the final design and final operation decision to be concluded by mid-2025», Mr. Ask says.

Since 2008, Solvang has invested materially in developing new knowledge, making science and technology an integral part of our portfolio. Access to operations and data has been granted to research institutions and research fellows. Together we have published peerreviewed findings. Being an active part in technology collaboration has paid off. Among several achievements, our onboard carbon capture and storage project was spun into a full-scale pilot on board Clipper Eris in 2024. Another landmark this year was the 3rd-party scientific verification of our open-loop mode exhaust gas cleaning system, the scrubber which runs on four ethylene carriers and four VLGCs.
