The maritime industry’s elusive quest to achieve so-called ‘zero’ emissions continues. Where it ends is not a one-size-fits-all discussion.The year-end maritime industry discussions tend to move away from global influence and back drift to national and domestic debates. As this happens, a positioning of a relatively small group of American owners and operators prepare for the upcoming business year and markets. The propulsion debate continues to be future fuels based upon sustainability and climate change.

Ships trials reportedly confirmed that CM Technologies’ new scuffing sensor can detect early onset cylinder wear in marine diesel engines. Trials onboard a number of large containerships and a two-stroke engine Baltic ferry showed it was possible to measure the friction in the cylinder when the engine is running.CMT noted a trend in cylinder liner scuffing following the widespread use of 0-0.50% low sulphur fuel (LSF). These fuels together with insufficient or over lubrication
