MAN Diesel & Turbo has announced the introduction of its Liquid ME-GI (Liquid Gas Injection) engine. The Liquid ME-GI is powered by LPG (Liquid Petroleum Gas), a smaller market than LNG but of significance in certain segments such as the small tankers that ply river traffic and coastal shipping routes.

Diesel Engine Cooling System – Water Purifiers Instead of Chemicals for Color Line

Filed Under: General
Early on in the evolution of the marine diesel engine it became evident that even good quality jacket cooling water contained microscopic particles that would build up to insulate the cooling surfaces. Scale was found to seriously diminish both engine efficiency and engine life, thus engine manufacturers looked to the laboratory for answers as to how this unwelcome reaction between very hot water and metal might be prevented.The chemists suggested additives to the cooling system. The kind of mix that engine manufacturers demand be be added to a decent fresh-water supply nowadays mostly has a nitrite-borate base‚ with a complex blend of organic inhibitors, surfactants, alkali adjusters, dispersants and foam suppressers. Problem solved; or was it? Corrosion in the Cooling System and Disposal of Waste WaterLong term research by engine makers has revealed that despite, or even because of, the cocktail of chemicals added to the diesel cooling system, localised pitting occurs in the ja...

Nuclear Waste Ship Patched-up in Nick of Time in North Sea

'Puma in trouble on its way back from Murmansk', Kjesti Album's headline news item set alarm bells ringing in Norway when it was published in the environmental online publication Naturvernvorbundet just before Christmas. Somewhat clandestinely, the Danish ship had sailed along Norway's north-west seaboard a week earlier to Murmansk, Russia, loaded with 333 tons of weapons-grade nuclear hazardous waste from a Serbian research facility. The 1994 built, 2120 dwt Puma attracted unwelcome publicity on the way back south from the Barents Sea, close by the northern coast of Norway, when crew were unable to stop the engine room flooding from a damaged sea-water inlet valve and assistance had to be called. Norwegians breathed a collective sigh of relief when they heard that all hazardous waste cargo had already been offloaded, but still the Puma was in danger of foundering in these icy waters off the coast of North Norway.

Olympic & Sealandia – New Year Centenary Retrospective

New Year may excuse a look back a century in time to recall what was happening in our area of interest during the year 1911. It was a year worth remembering, one in which Sealandia, the first ocean-going cargo ship with diesel engine propulsion was launched, and in the same year Olympic set out on her maiden voyage with propulsion shared between the new-wave steam turbine and the steam reciprocating engine.Joseph Conrad described the modern passenger ship as, "A marvel of applied science on its technical side, and an unpleasantly unsteady imitation of a Ritz Hotel in its social atmosphere." Conrad, compelling nautical author and sailing-ship era master mariner recorded this impression in his 'Ocean Travel' essay after a transatlantic passage he made in the nineteen twenties. In their separate ways both Olympic and Sealandia exemplified two such marvels of applied science as Conrad had in mind.SealandiaThe 6,800 dwt Selandia, the world's first ocean-going ship propelled by a diesel engi...

Dual-fuel to LNG Marine Engines – One Step Closer

By George Backwell at December 26, 2010 23:00
Filed Under: General
Dual-fuel marine diesel engines are increasingly being fitted to new-buildings where twin benefits of negligible noxious gas emissions (thanks to squeaky-clean combustion) and  economical performance come to bear when the engine operates in LNG mode. Indeed analysts are agreed that it is only the sparse availability of LNG bunkering facilities world-wide that limits installation of far greater numbers of dual-fuel systems at a time when prices for oil fuels are uncertain, and when environmental regulations are becoming increasingly stringent. For vessels with ready access to LNG as a fuel source, there has been a natural progression in the fitting of dual-fuel engines, beginning with large LNG carriers themselves using boil-off cargo gas when loaded.  Now that progression has extended to include far smaller ships (with a no less an important role in drilling operations) which also have ready access to the fuel  – LNG Platform Supply Vessels (PSV's). PSV's in the... [More]

Disney Cruises Disney Dream – 'Lego' Built, Diesel-electric Propulsion

Disney Dream, Disney Cruises latest Caribbean cruise ship of 128,000 GT and 4,000 passenger capacity was delivered by German builders Meyer Werft on 15, December 2010 and is scheduled to make the transatlantic crossing for a maiden cruise departure on 26, January 2011 from home base Port Canaveral, Florida.  A Disney publicity department staffer described the cruise liner as offering guests, "A perfect blend of elegant Art Deco style and fun-filled Disney whimsy to create one of the most spectacular ships afloat." Yet apart from the hype, which is forgivable considering competition in the growing cruise marketplace, there has been little mention of the state-of-the-art construction of this huge liner, the biggest ever built in Germany, and of its hi-tech propulsion.Laser and 'Lego' Shipbuilding Disney Dream first began taking shape early 2009 using 'Lego' building principles in a totally enclosed weather-proof building hall enclosing the dry dock at Meyer Werft's shipyard at Pap...

Greenhouse Gas Emissions – New Consumer Guide to Eco-friendly Ships

Richard Branson (founder of the iconic Virgin brand that includes Virgin Airways) has put his financial muscle behind the launch of an apparently non-profitmaking website, ShippingEfficiency.org that assigns a 1 to 7 rating for greenhouse gas emission to each and every ship (excepting naval vessels) in a database of about 60,000 ocean going ships.  Branson and like-minded business leaders have it in mind by this means to blow the whistle on ships that fail to measure up in the fight against global warming.Leader of the project, Peter Boyd, explained the idea in a Sky News interview on 6, December 2010: "You can go online and see an estimate of how clean or dirty the ship is." Meaning that owners can show details of their fleet to eco-friendly shippers and potential charterers, enabling international brand name shippers with global trading patterns to pick ships with the best eco-friendly ratings to carry their products. It is with this business spin-off in mind that may lead some ... [More]

Nuclear Power for Tanker Propulsion – A 'Work in Progress'

"We believe that as society recognises the limited choices available in the low carbon, oil scarce economy...  we will see nuclear ships on specific trade routes sooner than many currently anticipate." This prediction came from CEO Richard Sadler of British classification society Lloyd's Register as he announced membership of a new 'think tank' on 15, November 2010. Lloyd's Strategic Research Group has joined hands with a research consortium that aims to produce a practical concept design tanker fuelled by a 70 MW nuclear reactor, setting itself a two-year time-frame for the project. Other members are US-based Hyperion Power Generation, who are expert in small modular nuclear reactor technology; innovative British ship design group BMT; and Greek shipping conglomerate, Enterprises Shipping and Trading S.A. The consortium chose a tanker design for its initial project as nuclear power appears suited best for large deadweight vessels that are at sea for much of their time, but whethe... [More]

Carnival Cruise Liner Fire – Towing Winch by Markey Machinery There for the Long Haul

Carnival cruise liner Carnival Splendor was left drifting helplessly about 55 miles off the Baja California coast after being disabled by an engine-room fire on 8, November 2010, with 3,299 passengers and 1,167 crew on board. Fortunately powerful sea-going tugs, among them the tugboat SMBC Monterrey, stationed not far away at the Costa Azul, Mexico, LNG terminal, were on hand to help tow the stricken Carnival Cruise liner to San Diego. Indeed the tow made such rapid progress that it was possible to disembark the unhappy passengers on US soil instead of the nearest Mexican port of refuge.Towing the giant 113,300 gt, 952 ft cruise liner, would pose problems for many tugboats, especially in Pacific Ocean swells, but not for the powerful SMBC Monterrey, built in the UNV shipyard in Valencia, Spain, around Markey Machinery's DESDF-48WF high-speed, 760-hp double drum waterfall-type electric hawser winch.According to the online Maritime Reporter in August 2009 in an article 'Push and Pull', t...
