Cutting-edge 14,000 TEU Containership Enters NYK Fleet
In February 2016, a new, advanced 14,000 TEU containership entered the NYK fleet.
The vessel, NYK Blue Jay, employs a hull form that allows for improved cargo-loading efficiency, mainly achieved by minimizing engine-room space.
Moreover, the vessel’s main engine is equipped with the world’s first system (patent pending) featuring two power ranges (high and low) that allow for high speed operations and result in an improved fuel-consumption rate when slow-steaming, resulting in a significant reduction of both carbon dioxide emissions and fuel consumption. These innovations will enable the vessel to achieve the greatest operational energy savings in the shipping industry, in addition to cost competitiveness that would favorably compare with larger vessels capable of carrying 20,000 TEUs.
NYK Blue Jay is the first of 10 similar containerships, and the other nine vessels will be delivered and chartered by June 2018.
NYK Blue Jay has been put into service between Asia and Europe, and continues the company’s efforts to provide higher quality and more competitive services for our customers.
Fueling Ships with LNG Instead of Heavy Oil【LNG Tugboat・LNG PCTCs(Pure Car and Truck Carriers)・LNG Bunkering Business】
Vessels currently use heavy oil to run ship engines. However, changing from heavy oil to liquefied natural gas (LNG) would result in emissions reductions of about 30% for CO2, about 80% for NOx, and 100% for SOx. In October 2011, the NYK Group established its Fuel Project Team to research the viability of a fuel changeover and the development of related technology. In December 2013, we decided to begin building an LNG tugboat incorporating a dual fuel engine that can use both bunker oil and LNG as fuel(Delivered in August 2015). Excluding LNG carriers, this will be the first building of an LNG-fueled vessel in Japan. A few months later, in March 2014, we signed a contract to construct two dual-fuel LNG pure car and truck carriers (PCTCs), a world's first.
These dual-fuel LNG PCTCs will satisfy new SOx emission regulations that will go into effect in the North Sea and Baltic Sea from January 2015. The vessels will have dual-fuel LNG engines that will be capable of operating on either (1) LNG fuel or (2) heavy fuel oil and marine gas oil. Of course, gas emissions will fall considerably when LNG is used. Moreover, the NYK Group will expand its expertise in this field by building and operating these vessels and will look to expand this LNG fuel system to larger vessels or to other types of ships.
In addition, NYK has signed a contract to construct the world's first LNG bunkering vessel to provide LNG to LNG-fueled vessels and start an LNG supply and sales business jointly with GDF Suez and the Mitsubishi Corporation. The business will be based at the port of Zeebrugge, Belgium, and will begin operations from 2016.
Japan's First LNG-fueled Vessel “Sakigake”
On August 31 at the Oppama factory of Keihin Dock Co. Ltd.,NYK received delivery of Japan’s first LNG-fueled tugboat. The vessel has been named “Sakigake” and is expected to confirm the viability of LNG (liquefied natural gas) as a marine fuel and to help cultivate a new business field in the area of LNG as an environment-friendly marine fuel.
Sakigake was chartered from NYK to the Wing Maritime Service Corporation and is currently being operated mainly at the ports of Yokohama and Kawasaki. The new tug is equipped with dual-fuel engines that can use either of LNG or diesel oil, depending on conditions. Compared with conventional tugboats that use marine diesel oil, Sakigake emits about 30 percent less carbon dioxide, 80 percent less nitrogen oxide, and absolutely no sulfur oxide when using LNG as fuel. Three Patents are pending for the LNG receiving system and LNG carburetion system used on board.
LNG for this vessel is supplied from a tanker truck at a pier in Yokohama, and much effort has been made together with the supplier, Tokyo Gas Co. Ltd., to establish a method for the LNG to be safely and efficiently supplied in compliance with relevant laws and regulations. In fact, in July 2015 a trial fueling of the vessel from a tanker truck was successfully carried out for the first time in Japan.
This vessel has received a number of awards, such as the Technological Development Award at the 17th annual Logistics Environment Awards sponsored by the Japan Federation of Freight Industries (JFFI) and the Technology Special Award at the 2015 Ship of the Year Awards sponsored by the Japan Society of Naval Architects and Ocean Engineers (JASNAOE).
Next-Generation Car Carrier Delivered “Aries Leader”
In May 2014, NYK took delivery of a new pure car carrier, Aries Leader, the very first post-Panamax car carrier in Japan. We were able to enlarge and redesign the typical car carrier to increase its capacity and include the latest energy-saving technologies, detailed below. As a result, we expect a 30% reduction in carbon dioxide (CO2) emissions per unit compared with existing large pure car carriers.
Some of the carriers energy-saving technologies
Hybrid turbocharger: In addition to basic functions, the new hybrid turbocharger utilizes the extra rotational power of the turbine to generate electricity. By utilizing “waste” energy, the turbocharger boosts the output power of the engine by enabling it to aspirate at a level higher than that for the original engine displacement.
Electronically Controlled Engines: An electronically controlled system optimally times fuel injection and the opening and shutting of exhaust valves, thus enabling the engine to operate at optimal combustion efficiency. In particular, this type of engine improves combustion efficiency because of the high level of fuel injection pressure that can be maintained even in the low-load range. Therefore, the improvement reduces the generation of not only CO2 but also NOx, soot, and smoke to a significant degree.
Water-emulsified fuel: A fuel compound composed of a stable mixture of water and heavy oil. When we use water-emulsion fuel, the suddenly heated water droplets explode and spread oil around in a fine mist that supports highly efficient combustion. In addition, the water mixed in with the fuel boils during combustion, trapping heat and reducing combustion temperature, which in turn reduces the NOx.
Next-Generation, Energy-Saving Fluorescent, E•COOL lighting system: Based on the cold cathode fluorescent lamps used in LCD monitors, the E・COOL lighting system realizes high brightness. The lamps also consume much less power and have a long service life. This new lighting system is expected to enable power savings of about 40% compared with conventional fluorescent lighting systems. We installed 52,000 E・COOL lights on 22 vessels in fiscal 2013.
In addition, Aries Leader has been equipped with an air-lubrication system, which is explained in more detail in the following section.
