“Docking of vessels for scrubber retrofits means that the vessel has no income in the period, so every minute and hour we can reduce our installation time means increased revenues for the shipowner,” says Svein Ole Strømmen, chief operating officer of Clean Marine.

A 140k compact hybrid scrubber from Clean Marine was recently installed onboard the VLGC “Cratis”, a very large gas carrier. This hybrid scrubber installation for the Dorian LGP eco-design VLGC Cratis took only 30 days to complete, including the vessel’s special survey work carried out both in drydock and alongside a berth at Keppel Shipyard in Singapore.

Clean Marine has so far installed hybrid scrubbers onboard six of Dorian LPG’s VLGCs with the seventh scrubber installation expected next month.

“The excellent planning work by Keppel Shipyard, combined with Clean Marine’s strong project management and Dorian LPG’s proactive and solution-oriented approach, allowed us to achieve an efficient and successful installation. During the hybrid scrubber retrofit installation, the vessel underwent a five-year Classification survey cycle and all typical maintenance works, including full hull painting, ensuring the most cost-efficient result for all project stakeholders,” says Svein Ole Strømmen.

“We are very pleased with our collaboration and close partnerships with Keppel Shipyard and Clean Marine in our projects. The execution of a hybrid scrubber installation, including special survey and maintenance work for our vessels within 30 days, surpasses our expectations. We highly recommend Clean Marine for their professionalism and for the efficient execution in installing scrubbers on our ships” says Dorian LPG (USA) chief executive John Lycouris.


Dorian LPG is a liquefied petroleum gas shipping company and a leading owner and operator of modern VLGCs. The company currently own and operates a fleet of 22 modern VLGCs, including 19 new fuel-efficient eco-design 84,000cbm and three modern 82,000cbm VLGCs.
