So far, international shipping companies and cruise lines have been responding to these rules primarily by switching to marine gasoil (MGO), burning lower-sulfur fuel oil, or sticking with higher-sulfur fuel oil and adding “scrubbers” to capture most of the sulfur being emitted by their ships’ engines. More recently, though, some of the shipping sector’s biggest players have unveiled plans to boost the use of liquefied natural gas (LNG) as a bunker fuel, figuring that LNG bunkering will not only help them meet existing regulations but the tougher rules likely to be implemented over the next few years. Today, we begin a short series on the opportunities and challenges associated with shifting ships from fuel oil to LNG.
