MAN 175D SCR System Wins IMO Tier III Certification

MAN Energy Solutions announced that its MAN 175D SCR system successfully completed its final Type Approval Test, and was awarded IMO Tier III certification by all major classification societies.

According to the power company, since the beginning of its development it has intensively tested the MAN 175D SCR system at its Frederikshavn, Denmark test center, and during the process the SCR technology has accrued more than 5,000 operating hours, both in Frederikshavn and aboard an operative offshore vessel.

“In order to deliver a very compact and cost-effective design, we have based the MAN 175D SCR system on our most cutting-edge technology," said Daniel Struckmeier, Head of Exhaust Aftertreatment, MAN Energy Solutions. "A great strength is its flexible arrangement and compactness that optimise the space typically available in confined engine-rooms.”

The MAN 175D SCR, due to its IMO NOx Scheme A certification procedure the system, can be installed directly without further on-board confirmation tests. The family concept of the MAN 175D SCR also allows the bundling of the full group of 175D engines into one parent-engine concept. MAN Energy Solutions reports accordingly that the type approval covers not only the 12V175D in all its released applications, but also the 16V and 20V versions, which will be launched in the near future employing identical SCR components as used in the 12V system.
