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.
The worldwide first with Methanol powered vessels will navigate with DNV GL Class the classification society announced recently.
The four 50.000 tdw tanker have been ordered by the Swedish shipping company Marinvest and the Norwegian company Westfal-Larsen at the Korean shipyard Hyundai Mipo Dockyards. The classification follows according the DNV GL regulation for fuels with low flashpoint. The very first tank ship shall be delivered by 2016.DNV GL says the sulfur free fuel with low flashpoint (Low Flashpoint, LFL) of about twelve degrees Celsius becomes more and more attractive for the maritime industry, because this fuel fulfills the upcoming SOx-limit values in the emission control areas.The vessels, which will carry the additional DNV GL mark LFL FUELLED, feature a secondary bunker system as well as an automatically leakage warning system with shot-off function and flame protection systems. Further building safety measures include the position of the tanks and fuel pipes.
The new MAN B&W ME-LGI dual fuel engine which can burn sustainable fuels has been chosen by Vancouver-based Waterfront Shipping for a series of 50,000 dwt methanol carriers. The engines exploit a fraction of the cargo as fuel to run on 95% methanol ignited by 5% pilot oil. MAN Diesel & Turbo officially designates the ME-LGI engine ‘ME-B9.3-LGI’ (LGI stands for Liquid Gas Injection).Ole Grøne, Senior Vice President – Low Speed Promotion & Sales – MAN Diesel & Turbo, said: “This order represents a real market breakthrough for our Liquid Gas Injection engine and is the first such, commercial project that is not reliant on external funding. Simply put, the ME-LGI engine was chosen for these carriers because it is the engine best suited to the application. The LGI engine is designed to handle low-flash- point, low-sulphur fuels like LPG and methanol, etc. Consequently, its green credentials are striking with emissions of sulphur being alm... [More]
The Schottel Navigator (NAV) has become a byword over the past 50 years for a reliable and compact propulsion unit suitable for use on an extremely diverse range of vessels including almost every kind of floating object, especially barges, ferries, working boats or floating cranes. In principle the NAV is a large scale mobile outboard plant, providing a vessel with 360 degrees steerable manoeuvrability. The manufacturers say they are soon to launch a new generation of Navigators and the NAV 200 makes its debut at the upcoming Europort 2013 Technology Expo.

For those who haven’t come across one, the NAV is an adaptation of the Schottel Rudderpropeller plus an engine and related equipment while the the unit’s base frame accommodates the daily fuel tank, which, for example, has a capacity of about 600 litres on the NAV 200. Installation is simple: the Navigator merely has to be bolted ... [More]
It’s not a secret anymore that the shipping industry today is facing some serious challenges with respect to meeting upcoming exhaust gas emissions regulations. The contribution from shipping to sulphur oxide (SOx) and nitrogen oxide (NOx) emissions today is considerable, thus the need for reductions. Three main alternatives – switching to low-sulphur fuels, installing exhaust after-treatment devices, e.g. scrubbers, or using natural gas – have been investigated to some extent, but very little information is available on methanol as a marine fuel.Methanol is a clean fuelMethanol does not contain sulphur. Emissions of particulate matter and NOx from methanol combustion in marine engines are expected to be lower than those resulting from the combustion of conventional fuels. Methanol is widely available, can be safely transported and distributed using existing infrastructure, and in 2012 it is currently much cheaper than marine distillate fuel based on energy content. I... [More]
A new dual-fuel marine diesel engine variant from MAN Diesel & Turbo, the ME-LGI, runs on liquid gas fuels – methanol, LPG, dimethyl ether (DME), and (bio-) ethanol as well as other, low-flash-point fuels – building on the manufacturer’s successful LNG /HFO dual-fuel ME-GI low speed engine plant introduced last year. MAN developed the ME-LGI engine in response to interest from the shipping world in using alternatives to heavy fuel oil. Methanol and LPG carriers have already operated at sea for many years and many more LPG tankers are currently being built as the global LPG infrastructure grows; in themselves a ready market once a suitable dual-fuel engine became available.Sure enough, the new engine, unveiled on 1, July 2013 was snapped up as MAN signed a Letter of Intent with Vancouver-based Waterfront Shipping for the installation of four MAN ME-LGI engines which will run on a blend of 95% methanol and 5% diesel fuel.
