Making the Case for LPG as a Marine Fuel
The sulfur emission control areas (SECAs) in place in North-America and Northern Europe, in combination with the upcoming global 0.5% limit on sulfur in 2020 (or 2025) and similar EU limits in 2020, call for alternative fuels as a means for compliance. Several alternative fuels are available and, at the same time, new fuel oil products with very low sulfur content have been introduced.In this respect, the ability of the new MAN ME-LGIP engine to run on LPG, which is a sulfur-free fuel…
Wärtsilä 34DF Engine Awarded EPA Tier III Certification
Wärtsilä marks another milestone for its Wärtsilä 34DF dual-fuel engine.The 34DF engine has been awarded the U.S. Environmental Protection Agency’s (EPA) Tier III certification for diesel mode operation when installed together with the Wärtsilä NOx Reducer (NOR) system, a selective catalytic reduction (SCR) system that converts nitrogen oxides (NOx) with the aid of a catalyst into diatomic nitrogen (N2) and water.Wärtsilä said it is the first engine manufacturer to be awarded…
WinGD Celebrates Milestone Order for 100th X-DF Engine
Only five years after the launch of the X-DF engine, WinGD has announced they have secured an order for their 100th X-DF engine. The award-winning technology developed by WinGD has demonstrated, on tests and engines currently in operation, that it offers stable combustion, inherently low NOx and greenhouse gas emissions and high overall system efficiencies as well as reliable and safe gas operation. GasLog LTD, one of the early supporters of the X-DF technology, has eight LNG carriers, each with 2x 5X72DF main engines in its fleet with three new builds recently entering commercial operations.
Dual-Fuel Engine Hits 10,000 Hours on Ethane
Hartmann Reederei, the German ship-management company, has confirmed that two of its vessels – the 36,000 m3 LEG (liquefied ethylene gas) carriers Gaschem Beluga and Gaschem Orca – powered by the world’s first ME-GIE (-Gas Injection Ethane) two-stroke engines have collectively accumulated 10,000 hours of operations since entering operation at the end of 2017.The carriers were ordered by Hartmann and Ocean Yield of Norway, and constructed at Sinopacific Offshore Engineering (SOE)…
HHI to Build First LPG-Powered Dual-Fuel Engine VLGC
Hanjin Heavy Industries (HHI) has announced that it will construct two Very Large Gas Carriers (VLGCs) in their Philippines Facilities for EXMAR, the Belgian integrated gas shipping company. The 80,000 m3 newbuildings will each be powered by an individual MAN B&W 6G60ME-LGIP Mk9.5 engine. MAN Diesel & Turbo reports that the VLGCs have chosen LPG as a fuel option so they can comply with the new IMO sulphur-emission legislation due to enter force in 2020. Engine delivery to the yard has been scheduled for December 2019. Upon construction, the carriers will be chartered by Statoil.

A New Breed of Tug
When markets expand niches are created, goes the logic. For builders of tugs, that market is “floating gas” and the expanding use of liquefied natural gas, or LNG, as a fuel. In support of LNG, there’ll be more oceangoing tug duty — the new floating storage and regasification units, or FSRUs, mean busier LNG carriers, and LNG cargo owners have an interest in tug escorts that share their “carbon footprint”. Still, new emissions rules offer ways to keep using refinery products, and the work of master tug designers suggests the new breeds of tugs are about more than fuel.
Engines Selected for CMA CGM’s LNG Mega Ships
WinGD X-DF engines will power CMA CGM’s record setting containerships. French shipping line CMA CGM has chosen WinGD’s largest, 92 cm bore, dual-fuel low-speed engine to power its series of groundbreaking box ships – presently the largest on order globally, and the first ultra large container vessels with capable of running on liquefied natural gas (LNG). The series of nine ultra-large 22,000 TEU capacity containerships will be built at Hudong-Zhonghua Shipbuilding (Group) Co., Ltd.
LNG: Maritime's 'Fuel of the Future'
As the maritime world increasingly mulls alternative fuel and propulsion solutions, Maritime Reporter & Engineering News discusses the path ahead for (liquefied natural gas (LNG) with Timo Koponen, VP, Flow & Gas Solutions, Gas and LNG, Wärtsilä. The road toward acceptance of LNG as marine fuel has neither been short nor straight, but anyone who knows this market could not reasonably expect anything different. “Even though it (LNG) is very well proven both from the technology side and its benefit to the environment, nevertheless there are too many people who still doubt,” said Koponen.
Germany Orders LNG Fueled Research Ship
The Fassmer shipyard in Germany is currently cinstructing a new research vessel to be owned by Bundesamt für Seeschifffahrt und Hydrographie (BSH), the Federal Maritime and Hydrographic Agency. The new 75-meter-long ship, the Atair, will replace her 30 year old namesake, and will be the first German research vessel operating on liquefied natural gas (LNG) fuel. The engines for the new vessel will be supplied by Wärtsilä, who will also supply exhaust cleaning systems based on selective catalytic reduction (SCR) technology and the LNGPac system for complete fuel gas handling.
Wärtsilä 34DF Engines Certified EPA Tier III
Wärtsilä said it has been awarded model year 2017 certification of emissions compliance from the U.S. Environmental Protection Agency (EPA) for its Wärtsilä 34DF dual-fuel engine family. The EPA Tier III certification and the corresponding EIAPP certificate were both issued in March 2017. The Tier III certification of conformity covers the Wärtsilä 34DF engines manufactured from the date of issue until the end of 2017. These are the first Category 3 Tier III certificates issued by the EPA to any manufacturer.
