NYK: No oil leakage from tanker Takamine in Tokyo Bay

  On May 16 and 17, a few media outlets reported that crude oil had leaked from Takamine, a tanker operated by NYK Line, while the ship was discharging at JST 9:28 p.m. on May 15 at Keihin Kawasaki sea berth in Tokyo Bay. However, there are no indications that any leakage of oil occurred from this ship. The vessel has subsequently sailed safely toward its next port. NYK expresses its sincere regret to the community and all relevant persons for the concern caused by these media reports, and the company will continue its efforts to maintain safe operations on all NYK ships. Source: NYK LineIn the onset, I was frank with you propecia before and after has changed my subsistence. It has become much more fun, and now I have to run. Just as it is fabulous to sit.

NYK orders next generation LNG carriers to transport shale gas

  Mitsubishi Heavy Industries (MHI) has received an order for two "Sayaringo STaGE," a next-generation LNG (liquefied natural gas) carriers, for delivery to Nippon Yusen Kabushiki Kaisha (NYK Line). The carriers on order feature a new design that achieves significant improvements in both LNG carrying capacity and fuel efficiency through the adoption of a more efficient hull structure and an innovative hybrid propulsion system. The vessels are scheduled for completion and delivery in 2018. They will be put into service for transporting shale gas produced in North America, carrying the gas from Cameron LNG Project, an initiative in which Mitsubishi Corporation is participating. The order for two Sayaringo STaGE LNG carriers was received through MI LNG Company, Limited, a joint venture between MHI and Imabari Shipbuilding Co., Ltd. The vessels will be constructed at MHI's Nagasaki Shipyard & Machinery Works. Specifications will be LOA (length overall) of 293.5m, width of 48.94m, depth of 27.0m and draft of 11.05m. The carriers will respectively have four apple-shaped tanks, an improved version of Moss-type tanks designed with a bulging upper half. Total holding capacity of the tanks will be 165,000 cubic meters (m3). The adoption of a tank cover integrated with the hull ...

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 ...
