An unusual kind of ship is taking shape in the STX Finland shipyard in Turku, Finland. The Aura ll, due for delivery in spring 2012 for multipurpose operations in the Baltic Sea for Finnish owners Gaiamare (a subsidiary of the Meriaura Group) is designed to carry bulky lifts of Finland's lumber, containers, or even wind-farm modules on a spacious deck; while if occasion demands, even to operate as an oil-spill response vessel. That’s not all though: down below are three Wärtsilä 6L20 main generating sets that will power diesel-electric propulsion by means of either liquid bio-fuel (LBF) or MDO making this unique 4,350 dwt ship truly adaptable both above and below decks.

Outboards – World's Most Powerful & an Eco-friendly Battery-powered Alternative

"The most powerful outboard in the world" claimed newish U.S. company Seven Marine when they unveiled their 557 hp outboard at the NMMA Miami International Boat Show last month. The all aluminium 6.2 liter supercharged V8 engine was sourced from GM where it normally growls under the hood of the Cadillac CTS-V sports sedan. Obviously a gas-guzzler, it seemed an interesting idea to juxtapose here Seven Marine's mutation of the 557 beast against an outboard from German manufacturers 'Torqeedo' which also employs cutting-edge technology to attain entirely different goals. First the big fellow that promises to push power boaters back in their seats when they open up the throttle.The Seven Marine 557 Outboard   (Photo courtesy of Seven Marine)   The basic premise that led to the adaptation of this auto engine for marine propulsion was that a pair of these powerful outboards would achieve the same performance for a 45-ft powerboat as would require the fitting of four 300-hp ou...

Disney, Norwegian & Princess Cruises – Port of LA 'AMP' Clients

Disney Cruise Line, Princess Cruises, and Norwegian Cruise Line ships have all been provided with 'Alternative Maritime Power' (AMP)  while berthed in the Port of Los Angeles over the past few weeks according to a Port correspondent on 24, February 2011, who also quoted Mayor Villaraigosa's proud statement that: "The use of AMP at our World Cruise Center [located in San Pedro] reduces emissions not just at the Port, but improves the quality of air throughout the Los Angeles region".It sounds as if something noteworthy is afoot in sunny San Pedro, but coincidentallly the AMP concept is still widely known by another term with roots in the maritime past. Alternative Maritime Power (AMP) – 'Cold Ironing'AMP is known colloquially among many seafarers as 'Cold Ironing', a term stemming from the early steamship days when coal-fired boilers supplied steam to drive reciprocating and steam-turbine main engines. Once in port these boilers would be shut down to become literally  'c... [More]

Green by Design 'Emerald' – Bestway, Shanghai & LR Complete Project

'Emerald', a Midsize concept bulk carrier of 35,000 dwt, designed jointly by Bestway Marine Engineering Design of Shanghai and classification society Lloyds Register, bettered by 18% existing performance of standard bulk carriers as measured by the International Maritime Organization (IMO) 'Energy Efficient Design Index' (EEDI) according to the project leaders' announcement on 1, February 2011.It may be helpful to explain briefly 'EEDI', since it provided base measure for the  'Emerald' design team's work, and an associated new regulatory development also seems worth mentioning here.Energy Efficiency Design Index (EEDI)EEDI relates to efforts by IMO to limit global warming through pollution of the environment by marine engines, allowing a specific figure for an individual ship design to be calculated by means of a fairly complex formula. It is expressed in grams of CO2 per ship's capacity-mile, and a smaller EEDI value indicates a more energy-efficient ship design. The far more co... [More]

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]
