The Russian Sovcomflot (SCF Group) ordered two ice2 class LNG carriers last year with STX, S.Korea. The Atlantic-max carriers have capacity of 170,000 cubic meters using a reinforced membrane structure. Vessels of this capacity have a LOA of approximately 980 ft and beam of 150 ft. The vessels use a dual fuel electric propulsion system giving 19.5 kn comprising two 8L51/60DF engines of 8MW at 514 rpm and two 9L51/60DF engines of 9MW at 514 rpm. The engines will be built at the MAN Augsburg factory for delivery end 2012. [More]

Megayacht Designed for Dual Fuels

Italian builder Fincantieri, together with engine manufacturer Wärtsilä and designer Stefano Pastrovich have put forward a 325 ft megayacht concept called X-Vintage, using the dual fuels of LNG and MGO. The impending IMO Tier 3 regulation deadline of 2016 and the expected expansion of Emission Control Areas, using LNG avoids the necessity of having to incorporate exhaust treatment equipment to ensure compliance with the forthcoming regulations. In the X-Vintage, the twin tanks are located forward of the “garage for toys” where the headroom, out of necessity to accommodate some of the toys, is greater than on the other decks. A twin shaft electric propulsion system is specified with six Wärtsilä 6L20DF dual fuel generators each rated at 1,056 kW at 1,200 rpm. [More]

Specialist ship owner Anthony Veder, Netherlands, new LNG carrier ordered from Mayer Werft, Germany is due for delivery in the second quarter of 2012. A direct mechanical drive system is specified for the vessel which is believed to be the first application of its type. The new LNG carrier has a capacity of 550,000 ft3 (15,600 m3) with a LOA of 512 ft (156 m) The single shaft propulsion system comprises a Wärtsilä 50DF dual-fuel engine going through a reduction gearbox to a controllable pitch propeller. Operation on LNG all but eliminates SOx emissions and reduces the production of CO2 and NOx to levels that are sufficiently low as to be within the IMO Tier 3 NOx regulations and compliant with the requirements of the ECAs.

LNG Diesel Electric Engines for Trail Blazer Dutch Waterway Tanker

A unique Netherlands waterway tanker – the first with diesel-electric propulsion powered entirely by LNG – will soon ply the busy 2,000 km commercial waterways that connect to Europe’s industrial hub and account for about 40% of all international freight movements in the Netherlands. The LNG Greenstream Tanker, fruit of two years R&D and negotiation with statutory authorities and consultants, is scheduled to be delivered from the Kampen yard of builders Peters Shipyards later this year. The 110 m LOA river and canal tanker represents a leap in faith by owners Interstream Barging, who are putting money on their bet that LNG will become the fuel of the future on Europe’s waterways; confident enough not to hedge the bet by going for a dual-fuel engine.

Marine Diesel Engines – Oil Fuel Tax Alarm May Hasten LNG Progress

The international maritime sector is prime candidate to take the hit of a tax on shipping bunkers, analysts are convinced, after recent U.N. Climate Change talks in Durban agreed the design of a 'Global Climate Fund' to channel up to $100 billion a year to compensate poorer nations whilst leaving open the question of where the money would be coming from. Oxfam and green group WWF tabled a Durban motion calling for a carbon levy of  a massive $25 per tonne oil bunker tax but failed to obtain a consensus, nevertheless firing a warning shot across the industry’s bows. Latest news of advancements in the LNG fuel project for diesel engines, and a bullish forecast for future growth in LNG take-up follows below. LNG Supply Side DevelopmentsWorld-wide expansion plans for new LNG bunker station are reported by Zeus Intelligence listing in the past week supply proposals in such varied locations as on the Yangtze River; Port Fourcheon, Louisiana; Trinidad in the West Indies, and a...

Filed Under: Company News
Caterpillar Marine Power Systems recently announce the development of a new MaK M46DF series as a dual fuel engine suitable for electric or mechanical propulsion. The 46DF series is offered with a power output of 900 kW per cylinder at both 500 and 514 rpm engine speeds. When operating on LNG, it complies with IMO III as well as EPA Tier 4 regulations.
The new M46DF series has the same main dimensions and interfaces as the 43C series, simplifying the substitution of the 46DF engine in 43C applications and there is the possibility to retrofit existing 43C engines to dual fuel operation. Availability of the DF series is 2014. [More]

Post Panamax Solar Hybrid Supertanker

Sauter Carbon Offset Design (SCOD) presented earlier this month, their latest project, Emax
Deliverance - a DynaWing Solar Hybrid Supertanker. The 330,000 dwt tanker is designed to
pass through the larger locks of the post 2014 Panama Canal. The hull is slender and uses a
Mitsubishi Air Lubrication System (MALS) that reduces resistance and therefore delivers higher
efficiency. Propulsion is by a twin arrangement of a pusher propeller with a counter rotating
puller propeller on steerable pod, powered by W„rtsil„ dual fuel LNG engines with additional
power coming from a Solbian solar power generating array, in addition there are twenty masts
supporting DynaWing sails. A nett benefit is claimed to be a reduction in GHG emissions of
between 70 to 85 per cent equating to a total reduction of CO2 of 3 million tons over the 25 year
life of the vessel. [More]

The product tanker MV Bit Viking has completed the first ever conversion worldwide, of a vessel from HFO to LNG and is now in service operating along the Norwegian coastline . The very low emissions now attainable will qualify for lower Norwegian NOx emission taxes. The Bit Viking has a very high safety specification, delivered in 2007, the double hulled product tanker of 24,783 dwt has an LOA of 580 ft (177 m) and a beam of 82 ft (26.3 m). The conversion required a major rebuild of the engines from Wärtsilä 6L46B to 6L50DF engines with output of 7,460 hp (5,700 kW). Although having the same stroke as the old engine, required increasing the cylinder bores from 460 mm to 500 mm and replacing most of the engine parts. Safety analysis and approval was undertaken by Germanischer Lloyd (GL) classification society. [More]

In a project sponsored by the European Regional Development Fund, Europe’s first dual fuel inland waterways barge, the MTS Argonon, recently completed acceptance trials for ship owner Deen Shipping, Netherlands. Trico, Netherlands completed her fitting out as an inland waterways tanker. The double hulled vessel has a LOA of 360 ft (110 m) and 6,100 dwt. Propulsion is by twin Caterpillar 3512 DF dual fuel engines with an output of 1,500 hp (1,118 kW) and running on 80 per cent LNG and 20 diesel fuel. The LNG tank is installed on deck and provides sufficient fuel for a return trip from Rotterdam, Netherlands to Basel, Switzerland. A Dual Fuel Management System monitors demand and controls the gas supply according to power output of the engine, rpm, temperature and pressure in the engine manifold in also compensates for changes in ambient temperature, barometric pressure and fuel quality.

Nor Lines the Norwegian logistics and shipping company has ordered two liquefied natural gas (LNG) fueled cargo vessels of 5,000 dwt with an option on two further vessels, at Tsuji Heavy Industries (Jiangsu) Shipyard, China. The ship is a Rolls-Royce Marine design for a mixed cargo vessel and follows an Environmental Ship Concept (Environship) presented at the this year’s Nor-Shipping Exhibition and Conference and winning the Next Generation Award. The vessel has an LOA of 394 ft (120 m) and uses a Bergen B Series lean burn gas engine type B35:40 V12 developing 3,930 kW (5,268 hp) at 750 rpm. A Hybrid Shaft Generator (HSG)system is specified, reducing the need to run auxiliary gensets. The shaft generator can also operate as a power take-in motor thereby providing redundancy for the propulsion system. [More]
