Finnish Patrol Boat to Test Bio LNG Fuel
The Finnish Border Guard is testing bio liquefied natural gas (LNG) as fuel for a coastguard patrol vessel in an effort to lower greenhouse gas (GHG) emissions, thereby lessening the impact on global warming.The 96 meter long vessel Turva is fitted with Wärtsilä dual-fuel engines and has been supported with a Wärtsilä maintenance agreement since its launch in 2014. The Bio LNG fuel is supplied by Gasum, a Finnish state-owned biogas refiner. Bio LNG is a 100% renewable fuel that can reduce CO2 emissions over its lifecycle by up to 90% compared to conventional fuel.

Wärtsilä Rolls-out Pure Gas Marine Engine
Finnish corporation Wärtsilä has launched the 31SG pure gas engine for marine market applications.The 31SG is based on the successful Wärtsilä 31 product platform; the diesel version of the engine has been recognized by Guinness World Records as being the world’s most efficient 4-stroke diesel engine.The Wärtsilä 31SG engine further reduces the total cost of ownership and the environmental footprint for vessels operating in regions where there is a developed gas infrastructure.
Cummins Tech for IMO Tier III
Cummins Inc. revealed today the company’s solution for the impending start of International Maritime Organization (IMO) Tier III emission regulations, using proven Tier II engine technology and adding a Selective Catalytic Reduction (SCR) aftertreatment system. A unique feature will allow the ship’s crew to manually “pause” the SCR system whenever operating outside of a controlled emission area, thus reducing DEF usage and expenses for a lower cost of operation.The dual-tier strategy has another significant benefit…
Jan De Nul Launches Low Emission Vessel
Jan De Nul Group launched its fourth Ultra-Low Emission vessel last week in Singapore. It concerns the 6,000 m³ Trailing Suction Hopper Dredger Sanderus built at the Keppel Offshore & Marine shipyard.This green vessel is the first of two identical medium-sized hopper dredgers under construction at Keppel O&M’s shipyard in Singapore, fitted with a two-stage filtering technique for exhaust gases.In total, Jan De Nul Group designed six Ultra-Low Emission vessels (ULEvs) for its fleet: five Trailing Suction Hopper Dredgers and one Offshore Jack-Up Installation Vessel, the Voltaire.
Harvey Gulf PSV Receives Hybrid Retrofit
Harvey Energy, the first platform supply vessel (PSV) to be fueled by liquefied natural gas (LNG) will become the first PSV in the Americas to be hybrid retrofitted. The vessel's owner, Louisiana-based Harvey Gulf International Marine, has ordered an energy storage solution from the technology group Wärtsilä to significantly enhance Harvey Energy's efficiency and environmental performance.The installation of a Wärtsilä 1450 kW battery hybrid solution will reduce the ship’s exhaust emissions, fuel consumption, and noise level.
Project Forward Initiative Cuts CO2 Emissions
The Project Forward initiative led by Athens-Based Arista Shipping, with Wärtsilä as one of the participants, demonstrates that with LNG as fuel, an advanced hull design, and highly efficient propulsion machinery, it will be possible to meet the IMO’s target for a 40 percent reduction in carbon intensity by 2030.Model tests of the Project’s concept vessel indicate that the Energy Efficiency Design Index (EEDI) is well below the currently most stringent Phase III level. The EEDI reflects the CO2 emissions per transport work and is a measure of carbon intensity.

New Indicator Enables Early Damage Detection in Diesel Engines
New performance indicator enables effective fuel savings, increased efficiency and early damage detection in diesel enginesReliable results even at elevated pressure ranges up to 350 bar.Fuel consumption in shipping and the associated costs are enormous – it is not without reason that many operators pursue a slow steaming strategy. But this is not a permanent solution. In the “Safety and Shipping Review 2015” Allianz Global Corporate & Specialty warns that this technology shortens the life of the engine and increases polluting emissions.
Fuels, Lubricants & Green Marine
International Maritime Organization (IMO) fuel rules entering force in 2020 mandate a drastic sulfur reduction. By 2050 the mandate is to cut greenhouse gas emissions of shipping by at least 50 percent.Marine fuels, lubricants and additives manufacturers play their part in establishing maritime’s green credentials by introducing new environmentally acceptable technologies and products.The shipping industry is more than ever portrayed in a bad light due to increasing awareness of its contribution to global climate change, according to Dirk Kronmeijer, CEO of GoodFuels Marine.
MAN Diesel & Turbo, HHI-EMD Invest in New Test Facility
As the global maritime industry steams toward ever-stricter fuel and emission rules, industry leaders such as MAN Diesel & Turbo and Hyundai continue to invest in facilities and technologies.
