Ships are getting new bulbous bow to save fuels

Image Credit: WikipediaThe bulbous bow (bulb) is a very important part of the hull as it can potentially reduce the hull resistance considerably, or affect the resistance in a negative way.According to ABS 'Ship Energy Efficiency Measures Advisory' , the properly designed bulbous bow reduces wave-making resistance by producing its own wave system that is out of phase with the bow wave from the hull, creating a canceling effect and overall reduction in wavemaking resistance. The flow is more horizontal, reducing eddy effects at the forward bilge. Physical factors considered in bulb optimization include volume, vertical extension of the center of volume, longitudinal extension and shape. A bulb with a reverse pearshaped section is primarily effective at the design condition, pear-shaped bulbs work best for drafts below the design draft (i.e. ballast draft or partial load draft) and cylindrical shaped bulbs offer a compromise solutionThe characteristics of the bulbous bow must be carefully balanced with the shape of the entrance and the transition towards the forward shoulder and bilge. Bulbs are most effective at certain Froude number (speed-length ratio) and draft. Changes in speed and draft significantly change the wave created, such that reductions in draft or speed can actually lead ...

Adjustments reduce emissions from containerships

Remodeling of the ship's bulbous bow (Left: Before remodeling) (Right: After remodeling) Nippon Yusen Kabushiki Kaisha (NYK) and the Monohakobi Technology Institute (MTI), which is an NYK Group company, have made energy-saving adjustments to a containership resulting in a verified 23 percent reduction in carbon dioxide (CO2) emissions over half a year, greater than the amount estimated prior to the tests. To reduce energy consumption, containerships often sail at a speed that is much slower than the average speed anticipated when the ship was designed and built. To make existing ships more energy efficient at these slower speeds, the NYK Group has been conducting research since the summer of 2013, studying measures such as remodeling the ship’s bulbous bow and installing MT-FAST. Big Data analyses using actual voyage data gathered over half a year after the implementation of improvements in June 2014 were conducted by the NYK Group, and a 23% reduction in CO2 emissions was subsequently certified by the ship classification society ClassNK. The conversion was also verified not to affect the safe operation of the vessel or the operating condition of the engine. This adoption of energy-efficient technology is being supported by a grant provided through the Maritime ...

NYK wins award for Environmental Excellence

The 2014 NYK Report published by the NYK Group has been honored with an award for excellence in the environmental reporting category at the 18th Environmental Communication Awards, which are jointly sponsored by Japan’s Ministry of the Environment and the Global Environmental Forum, a non-profit organization based in Tokyo. This is the third time that NYK has been recognized at this event, following the company’s win of the Sustainability Report Grand Prize (the Environment Minister Award) in 2012 and the President’s Award for Excellence in 2013. This year’s report was highly evaluated for (1) the consolidation of NYK Group risks and opportunities into three priority topics aspects – i.e., environment, safety, and human capital development — and analysis thereof, (2) the company’s clear indication of its desire for sustainable growth and corporate-value improvement, such as by referring to ESG (environment, society, and governance) in the president’s message, and (3) the company’s indication of the future prospects of each business area along with correlating financial data. The NYK Group will continue to create reports that give stakeholders a better understanding of the company’s activities, while taking initiatives to approach social issues as a good corporate citizen and subsequently achieve a sustainable ...

NYK and Astomos Energy conclude time-charter contract for new VLGC

On February 27, NYK concluded a time-charter contract for a new VLGC (very large gas carrier) with Astomos Energy Corporation. The new VLGC will be built by Mitsubishi Heavy Industries (MHI) and delivered in the second quarter of 2017. NYK will charter the vessel from Kyoei Tanker Co. Ltd., and from its delivery, the vessel will be assigned to a service designated in a five-year time-charter contract with Astomos. Astomos' new medium-term plan, which starts from fiscal 2015, calls for an increase in LPG handling volume from the current 10 million tons/year to 12 million tons/year by 2017. Astomos plays an important role in the LPG business field, which is expected to continue to grow, particularly as progress is made on new LNG projects in the Middle East, the United States, West Africa, and Australia. This is the 11th VLGC for Astomos, and NYK will continue to reinforce its close, long-term relationship with the energy company.

NYK and Mitsui conclude time-charter contract for 2nd LNG carrier

On January 29, NYK concluded a time-charter contract with Mitsui & Co. Ltd. for a new liquefied natural gas (LNG) carrier for the Cameron LNG project based in the U.S. state of Louisiana. Mitsui & Co. Ltd. will take LNG produced from this project which promote in the U.S. state of Louisiana and this is second new contract, following the contract concluding with Mitsui & Co. Ltd. on September 26, 2014. The ship will be delivered in 2018 and assigned to transport this project’s LNG for a maximum of 25 years. The new vessel will be owned by Rosewood Shipping Pte. Ltd., a wholly owned subsidiary of NYK, and an NYK Group company will be responsible for ship management.
