Compared to HFO, LNG reduces emissions of sulphur by >99%, NOx by 80%, carbon dioxide by 20% and eliminates particulates in ship exhausts. In January 2021 the International Maritime Organisation (IMO) implemented its Global Sulphur Cap reducing allowable emissions from 3.5% to 0.5%. LNG can be used for many vessels including ferries, barges, cruisers and tugs.
Chart onboard LNG fuel gas supply systems comprise all elements for storage and delivery of natural gas to the ships engines:
Chart has provided LNG fueling systems for a variety of marine vessels including ships operating on China's inland waterways and high seas through to the world's fastest and cleanest high speed ferry.
Full service scope including delivery and commissioning according to applicable codes (DNV, LRS, BV, ABS, USCG).
Solutions for coastal, inland water boats and ships.
Systems can be incorporated into newly built and/or converted LNG fueled vessels.
River traffic can be intensive, moving goods and passengers on our main fluvial arteries. The associated emissions are a source of not only high local particulate emissions, but also of atmosphere warming CO2. Chart’s small scale LNG FGSS and upcoming liquid hydrogen FGSS allow existing vessels, as well as new builds, to be adapted to run safely and cleaner.
Chart's Changzhou, China facility engineered and built the LNG fuel tanks on Donsotank's Prospero vessel, which was named tanker of the Year 2021 for its environmental credentials.
Hydrogen has been identified as a potential marine propulsion fuel and Chart is already working with multiple stakeholders solving the challenges of onboard storage and developing the bunkering network.
Chart has provided a number of systems that enable LNG to be used in ports for power instead of diesel, including Hummel, a power barge that provides natural gas energy to cruise ships during layovers in Hamburg.
The small-scale LNG to Power terminal in Gibraltar is resupplied by sea and has been given approval to add a loading facility so it can indirectly refuel local sea going vessels by truck.
The small-scale import terminal in Lithuania incorporates bunkering and is a complete LNG import, distribution and fueling hub for the Baltic region.
Coastal receiving, storage and distribution terminals with jetty fueling module
Chart complete shore to ship bunkering terminals include cryogenic storage tanks, vacuum insulated piping, vaporization and loading arms.
Cryogenic storage tanks are shop built and other components typically supplied as modules, often skid mounted. This reduces construction time at site and allows future capacity expansions to be incorporated into the initial plant design.
Chart cryogenic tanks provide high thermal performance with extended hold times to deliver significantly lower lifecycle costs versus standard tanks.
Chart vacuum insulated pipe decreases heat leakage by 90% and offers a functional life 10x longer than mechanically insulated pipe.
Chart can always be relied upon for innovation to deliver the optimum solution. For example, this bunkering terminal in Norway fuels a fleet of feeder vessels serving offshore fish farms. An integral evaporation plant vaporizes LNG to provide natural gas for the boilers at the adjacent fish feed production factory.
