Market conditions, new emissions legislation and the relative prices of liquid and gaseous fuels have combined to multiply the number of propulsion and ship operating options open to owners purchasing large two and four-stroke engines. Power system engineering consultants FEV have analysed the range of choices and propose solutions according to ships and their applications.

Legislation and economics

After some uncertainties over the past few years, IMO has now released the guidelines for emissions reduction in the maritime sector for the medium-term period [ 1]:
  • — From 1st January 2016 onwards IMO Tier III limits oxides of nitrogen (NOx) in ECAs — countries adopting ECAs will set their own validity dates.

  • — The new limitations on oxides of sulphur (SOx) for ECAs will come in force on 1st January 2015.

  • — Stage I of the EEDI limits for carbon dioxide (CO2) is already in force and Stage II will follow on 1st January 2015.

Reduction in fuel consumption is a longstanding development aim in...
