New legislation prompts growing interest in retrofit

With the recent introduction of stringent environmental regulations, such as those from the IMO, shipowners and operators are increasingly obliged to operate their MAN B&W two-stroke main engines on ultra-low sulphur fuels in defined marine zones. CARB (the Californian Air Resource Board) has enforced the use of diesel oils (MDO) or gas oils (MGO) in Californian waters since July 1, 2009, while European harbours introduced similar requirements at the start of 2010.
