The keel laying of the world’s first LNG Hybrid Barge took place at a ceremony held at the ”SAM Shipbuilding and Machinery“ shipyard in Komárno, Slovakia in the second week of the new year. In  the  presence  of  representatives  of  the  shipyard,  AIDA  Cruises,  Becker  Marine  Systems  and Hybrid Port Energy (a subsidiary of Becker Marine Systems and the barge shipping company), the laying of the keel was carried out following the tradition of placing a coin on the keel block prior to lowering the first section.The start of cooperation between Becker Marine Systems and AIDA Cruises preceded this keel laying  in  the  summer  of  2012,  with  the  aim  of  supplying  environmentally  friendly  electricity  to cruise ships during their layovers at port. The LNG Hybrid Barge currently under construction for this is equipped wit... [More]

Flow-optimized propellers can reduce fuel consumption by up to ten tons per day To improve ships manoeuvrability and energy efficiency also the propellers play a big role. Worldwide leading manufacturer of ship propellers is the Metallguss GmbH (MMG) in Waren, Germany. The company produces also propellers with six blades with a diameter of up to 9,30 meters and a weight of 97 tons for example for container ships with a load capacity of 9.400 TEUs. The propulsion power of such 286 meters long and 48.20 meters ship with a draft of 14.50 meters is of one diesel engine with an output of max 52.290 kW. With this a speed of 22.3 kn is reached. Propellers of the "AIDAstella" have a diameter of 5.2 meters and weigh each 12.8 tons The propeller is pretty much decisive to transfer as much as possible of the engine energy into propulsion energy. With particular large diameters and very specific blade geometry an efficiency gain of three to four percent can be reached – with following posit... [More]

The first MaK dual-fuel marine diesel engine has been shipped out of the MaK Rostock, Gerrmany factory, announce Caterpillar Marine Power Systems, destined for the first of a new generation of AIDA cruise ships under construction by Mitsubishi Heavy Industries (MHI) at its Nagasaki Shipyard & Machinery Works. MaK M 46 DF Marine Diesel Engine: Photo credit: Caterpillar Upon arrival the new engine will be placed in the hull of the AIDA cruise ship now under construction (due for delivery in March 2015) as the first of two vessels ordered by the Costa Group member company. These luxury 124,500 gross tonnage cruise ships will have accommodation for around 3,300 passengers, and will be the largest ever constructed for AIDA Cruises.With a bore of 460 mm and stroke of 610, the M 46 DF engine is suitable for electric drive propulsion systems as well as mechanical propulsion systems. It has been designed to allow retrofitting of current M 43 C engines (three of which will also power the cr... [More]
