The newly developed SOx scrubber (naked scrubber) reduces total installed weight of infrastructure by more than two thirds, which means significant capex savings on the scrubber itself with no need to strengthen the ship structure prior to installation, the company said.

This simplified scrubber also reduces installation time from four to five weeks to three weeks, thereby also cutting docking costs. A pre-fabricated electric room is one of the solutions which will enable significantly shorter installation times. All critical components on the open deck scrubber will be protected from harsh sea conditions.

“In total, our new scrubber application is significantly more competitive than other scrubber applications on the market and compared to the alternative of using low sulfur fuels to meet the IMO2020 standards. This development is in response to many shipowners that have requested both lower capex and opex levels for marine scrubbers while being able to satisfy the IMO 2020 emission level requirements,” Nils Høy-Petersen, Clean Marine CEO, explained.

The compact “naked” scrubber is a hybrid than can run with both open and closed loop, thereby avoiding being stopped by ports that have prohibited the use of open loop scrubbers. It can easily be inspected and maintained by the vessel’s crew in order to maximise operational uptime.

It is made of high-grade stainless-steel material and can be easily incorporated with the ship’s boilers. It comes with a proven zero back pressure construction that has already in the past few years, has had more than 10,000 hours of operation with boilers. Favourable placement of electronics and simplified cable connections make it easy to install and maintain, which is often a time-consuming process during the installation, the company said.

“The big shipowners with a clear sustainability profile and plan seem largely unaffected by recent industry discussions. However, we believe this next-generation scrubber application could make it easier for other smaller shipowning companies to opt for a scrubber solution,” Høy-Petersen added.

Clean Marine’s revenues trebled from 2016 to 2018 and the company forecasts that 2019 revenues will be six to seven times higher than recorded last year. 

“It is fair to say that the scrubber market has slowed down in recent months, but we have invested in production capacity worldwide that allows us to handle large orders and shorten delivery times. Our current order backlog requires us to deliver eight to10 exhaust gas systems per month in the run-up to IMO2020. Instead of operating the vessels in the turmoil of January, 2020, it could be beneficial to install a scrubber during that difficult time. We still have available production slots for shipowners that require scrubbers for delivery in early 2020,” Høy-Petersen concluded.


Bureau Veritas company, TMC Marine, is to share scrubber insight and experience on 9th September at the beginning of London International Shipping Week (LISW).

Choosing the right system is vital, but operational and maintenance management are also vital to protect investment and ensure performance. TMC will advise on the exhaust gas cleaning (scrubber) projects – both from investment and operational perspectives.
