Bomin Linde LNG starts the implementation process for both terminals
The plans for building and operating the two terminals in Hamburg and Bremerhaven, the future hubs of the German coastal LNG supply, have come to maturity. Currently, Bomin Linde LNG is finalising preparations to enable manufacturing of the key parts and prompt construction of the LNG facilities. The terminals will be installed on a modular basis and will have sufficient flexibility to quickly meet a rise in demand.
Starting from the strategic hubs Hamburg and Bremerhaven, neighbouring ports such as Kiel, Lübeck, Rostock or Wilhelmshaven can be reliably supplied with LNG. "We are fully on track with the projects and will be able to provide ships in all German ports along the North and Baltic Sea with LNG as a clean fuel," said Bomin Linde LNG Managing Director Ruben Benders. "This is an important step to establishing LNG as a marine fuel," added Mahinde Abeynaike, also Managing Director of Bomin Linde LNG. "The s... [More]
To be honest: being a Graduated Engineer for Ship Operation Technology of the “old school” and for around 18 years up to now a specialized shipping journalist with a particular focus on combustion engines, I’m pretty much, let me say it politely: confused!
Wherever you read an article about gas fuelled engines everybody speaks about LNG-fuelled engines! Lately I read an article in the pretty much well-known daily German newspaper THB (Täglicher Hafenbericht=Daily Port Report) where the following is mentioned: “…Both ferries (Stavangerfjord and Bergensfjord) will be driven solely with liquefied gas (LNG) instead with heavy fuel”. But is this correct?
Most important question: what is LNG and why do we have LNG?
Natural gas (NG) is a mixture of different gases consisting primarily of methane. The higher the methane content (more than 90%) the better. Because the high methane number (MN) influences positively the combustion process. It is usu... [More]
Yesterday, the world’s first fuelling vessel for LNG (liquefied natural gas) was christened in a traditional christening ceremony in Stockholm, by Helena Bonnier, the chairman of Ports of Stockholm (Stockholms Hamnar), in the presence of the Minister of Infrastructure, Catharina Elmsäter-Svärd, among others.
In spring of 2012, the Swedish government decided to support what was then a TEN-T request about a LNG fuelling vessel. One year later, the ship is christened and constitutes as an additional component in a competitive maritime shipping with quality, safety and a strong environmental profile, says the Swedish Minister of Infrastructure, Catharina Elmsäter-Svärd.
The LNG fuelling vessel, Seagas, is the first ship in the world of its kind, and is classified under the same regulations that apply to oceangoing LNG-tankers. The fuelling vessel will on a daily basis, supply 60-70 tons of LNG to M/S Viking Grace, the new cruise-ship of Viking Line, when the ship ... [More]
Mitsubishi Heavy Industries (MHI) signed on the dotted line a few days ago to build a 138,000 gt LNG carrier in their ‘Sayaendo’ series for Mitsui O.S.K. Lines . MHI describe this 288m (945ft) long vessel as a ‘New-generation’ LNG carrier, with a multitude of new design features which add up, MHI claims, to deliver a 25% reduction in fuel consumption compared to that of conventional LNG carriers of the same size; but essentially the design is marked by two outstanding features. The first a dramatic change in the shape of the ship compared with the distinctive dromedary-like silhouette of other LNG carriers. Second a new turbine plant that achieves higher thermal energy by steam reheat.

LNG Tanks – 'Peas in a Pod' StyleThe name itself explains the concept: ‘Sayaendo’ in Japanese means ‘peas in a pod’. The ‘peas’ are the spherical LNG tanks, the ‘pod&r... [More]
MAN Diesel & Turbo together with Germanischer Lloyd have published a study analyzing the problem of the best way for container ships to meet the present and future exhaust emission regulations. The four technologies investigated in the study are: exhaust gas cleaning by scrubber, scrubber plus Waste Heat Recovery (WHR), LNG as a fuel and LNG with WHR. In the study, circumstances were considered for five sizes of container ship. The smallest is a feeder of 2,500 TEU going up to the largest of 18,000 TEU. For each ship size the speed, engine power, round trip distance and percentage of distance spent in Emission Control Areas is estimated proportionally. The study concludes that LNG offers lower emissions and given the right circumstances, less fuel cost. [More]
This year the Water Police that patrol the Netherlands inland waterways are experimenting with a dual fuel gasoline / CNG Honda outboard powered patrol boat. The boat is a 18 ft (5.6 m) Dolphin RIB powered by a Honda 90 VTEC outboard. In addition to the standard gasoline tank, there is a 24 US gall (90 liter) CNG tank with a capacity for 33 lbs (15 kg) of CNG, held under pressure of approx 3,000psi (~200 bar). The fuel system cold starts on gasoline and when operating temperature is reached switches over automatically to CNG and remains operating on gas under 2,000 rpm. Above that speed it switches over to gasoline to realise the full power of the engine. In practical terms, the boat can patrol all day on one tank of CNG, when speed is required, it is always available and the performance of the boat is not impaired in any way due to the dual fuel capability. The fuel cost of CNG compared to gasoline in the Netherlands is about half, giving a substantial through life cost saving. [More]
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]
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.

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.
