Development of LNG bunkering infrastructure critical to expanding interest in LNG-fueled vessels By John R. Snyder, Publisher & Editor in Chief

s the implementation of IMO’s 0.5% global sulfur cap draws closer—it goes into effect January 1, 2020—vessel operators will have to carefully weigh their compliance options and the potential cost implications of those strategies. The compliance choices aren’t vast: Switch from fuel oil to Marine Gas Oil, use exhaust gas scrubbers when you burn High Sulfur Fuel Oil or try an alternative fuel such as Liquefied Natural Gas (LNG) or methanol. While many ship operators are expected to switch to MGO, there could be limited availability of 0.5% sulfur fuel, perhaps initially only in major bunkering hubs such as Singapore, and the ports of Amsterdam, Rotterdam, and Antwerp. At Posidonia 2018 in Athens, Greece, early this month, DNV GL reported that there has been a dramatic rise in interest in emission reduction systems, especially scrubbers. As of May 2018, the total number of vessels either ordered or installed with scrubbers stood at 817—a jump of nearly 300 vessels in a space of only a few months, according to DNV GL. “This increase is due to several factors, but the trend is clear,” says Stine Mundal, Head

of Section for Environmental Certification at DNV GL – Maritime. “At the same time, we are seeing that bulk and container vessels are the segments with the most installations, overtaking cruise vessels which had been the early adopters. This indicates that owners are making their solution decisions now and many are choosing scrubbers to comply with emissions restrictions.” At the Marine Log Tugs & Barges 2018 Conference & Expo, this past May in Philadelphia, several presenters discussed the development of small scale LNG bunkering infrastructure—which will play into ship operators’ decisions to opt for LNG as a marine fuel to meet emission regulations. Speaking at Tugs & Barges 2018, Aziz Bamik, General Manager, GTT North America, Houston, TX, pointed out that there are currently 120 LNG-fueled ship and vessels in operation and another 134 on order or under construction—up from 100 in operation and another 101 on order or under construction in February 2017. Right now, there are 46 ports around the world that are supplying LNG and six bunker vessels supplying LNG as fuel. One of the newest will be the Clean Jacksonville, the first LNG transport barge in the U.S.—and first

of its type in the world—is nearing commissioning at Conrad Orange Shipyard in Orange, TX. Designed by Bristol Harbor Group, Bristol, RI, the 232 ft x 49 ft bunker barge has a single GTT Mark III Flex technology membrane tank with a capacity of 2,200 m3, with the ability to transfer LNG at 500 m3/hr. The Clean Jacksonville will support bunkering of TOTE Maritime’s two Marlin Class LNG-fueled containerships. LNG bunkering began at the Port of Jacksonville, FL, on January 9, 2016, with the fuelling of the first of those ships, Isla Bella. TOTE worked with its supply chain partners JAX LNG and Clean Marine Energy and other commercial partners and stakeholders in a phased approach to develop LNG bunkering. Prior to the commissioning of the Clean Jacksonville, The TOTE ships have been refueled using truck-to-ship LNG bunkering. The truck-to-ship bunkering operation uses ISO containers via a transfer skid. The skid system allows four chassis mounted ISO containers to be simultaneously offload LNG to the Marlin Class ships within 6 to 8 hours. The JAX LNG liquefaction plant under development is owned by JAX LNG, a partnership between Pivotal LNG, a wholly June 2018 // Marine Log 25
