Sinopacific builds cargo tanks for 9.686 cubic meter with BV-ClassThe future of the Natural Gas Shipping keeps a majority of the shipping industry busy. Again and again new equipment and machinery is developed. Such as in China. At present there arise the largest Bilobe-Liquid Gas Storage tanks.They are nearing completion at China’s Sinopacific yard and will be installed in a series of four 27,500 cu m semi-refrigerated LNG/Ethylene carriers building for Denmark’s Shipping Company Evergas. Each of the IMO Type C Bilobe tanks has a capacity of 9,686 cu m. Two of the tanks in each vessel will be supplemented by a third conical Type C cargo tank and a smaller LNG fuel tank on the deck of the vessels. International classification society Bureau Veritas is classing the world’s largest Bilobe-Gas Tanks.
A recent North European conducted survey of some of the biggest shipping companies in Europe shows that they will choose the low-sulfur marine gas oil when the new emission regulations comes into force next year.Some of Europe's large shipping owners without doubts will choose to use the more expensive, low-sulfur marine gas oil once the environmental regulations aimed at reducing the sulfur content in ship fuel comes into effect on January 1st 2015 in the European SECA zone. The alternatives to switching to marine gas oil with a lower sulfur content include continuing to use the traditional high sulfur fuel and cleaning it with scrubber (exhaust cleaning system), or switching to natural gas (LNG).
While a big number of shipping companies have announced intentions of switching to natural gas on the long term (there is no doubt: it will come), the survey shows that a majority of the carriers choose marine gas oil as the immediate solution, although it costs much more than fuel wit... [More]
France’s Brittany Ferries has ordered a huge 210-m long, 52,000 gt, almost 2,500 passenger capacity, dual-fuel cruise ferry that they claim will be the first in UK waters to use natural gas to power its engines. At the same time they claim it will be first in the world to employ technology that allows the fuel to be carried on board at close to atmospheric pressure.

STX France explains that the ship bears the self-explanatory code name PEGASIS (Power Efficient Gas Innovative Ship) and is one of 34 projects engaged in the ‘New Industrial France’ programme. According to Brittany Ferries four dual-fuel engines (natural gas and marine diesel oil) will be installed (they do not choose to name the engine builders at this stage) with a total installed power of 45 MW and LNG bunker capacity of 1,300 cu.m.Clearly, much forward bunker safety and logistical planning was needed, and Brittany Ferries say that t...

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]
