The majority of goods worldwide are transported by ships. In the next 5-10 years stricter regulations on the pollution from these vessels are coming into force. These include regulations for nitrogen oxides and carbon dioxide.

At the same time more stringent regulations on fuel sulfur content are introduced. A consequence is that the ship engines, for a large part designed by MAN Diesel & Turbo A/S in Copenhagen, and in particular the operation of the ship engines will be changed.

One of the major challenges in this context is to prevent "cold corrosion" in the engines, which has proven to be a bigger problem when “slow-steaming” (i.e. sailing at reduced speeds).

In this project, SULCOR, DTU, MAN Diesel & Turbo and the Danish strategic research council has teamed up with international universities in a challenging work to understand and articulate the mechanisms underlying the formation and condensation of sulfuric acid in the engines, in order to show ways to avoid the problems.

The project runs: 2015-2018
