China's Shanghai Bluesoul Environmental Technology has secured approval in principle (AiP) from global classification society DNV GL for the technical feasibility of its BlueSulf scrubber system.
The approval is the first of its kind for a scrubber under the new DNV GL rule.
DNV GL will provide advisory assistance to the project such as hardware-in-the-loop testing and simulations using its Complex Ship Systems Modeling and Simulation (COSMOSS) tool as part of the new AiP.
Other services to be contributed by DNV GL include analyses using computational fluid dynamics (CFD), and ultimately the final certification of the scrubber.
Shanghai Bluesoul’s BlueSulf is a hybrid scrubber system designed to switch between open and closed loop mode, and can easily adapt to changes in water salinity and requirements in different ports.
The system can operate on both seawater and freshwater, and can reduce the sulphur content in exhaust gas to 0.1% or less.
Shanghai Bluesoul Environmental Technology chief operating officer Jacky Chow said: “We are very pleased to be the first Chinese supplier to receive this AiP, and it demonstrates BlueSulf’s design complies with DNV GL class rules requirements by using the sodium alkali method to clean exhaust gases.
“We have signed three scrubber projects with Chinese and European owners and we are also in negotiations for several potential retrofit and new building projects.”
BlueSulf scrubber system users will also be able to comply with the requirements of the Chinese Emission Control Area that have been in force at 11 ports in China since 1 January, in addition to the upcoming global sulphur cap rule.
