Japanese Partners Developing Method to Assess Ship Performance in Actual Seas
NYK and Japan Marine United Corporation (JMU) have joined forces to develop a method for estimating a ship’s performance in actual seas before construction is completed.The aim of the two companies is predict a vessel's performance in actual seas before the conclusion of a shipbuilding contract and aid in the reduction of GHG emissions by procuring highly fuel-efficient vessels.In conventional shipbuilding contracts, the guaranteed speed is set and agreed based on the relationship between the ship's speed and horsepower in calm waters…
NYK, ABS, WinGD Working on Battery-Hybrid System to Cut GHG Emissions from Ships
NYK and NYK Group company MTI Co., Ltd. (“MTI”), together with the American Bureau of Shipping (“ABS”) and Winterthur Gas & Diesel Ltd. ("WinGD"), have started joint research for optimization of ship design by utilizing a battery-hybrid system to aid ship propulsion and thus reduce greenhouse gas (GHG) emissions from vessels.A vessel’s main-engine revolutions may increase significantly when a vessel tries to maintain its sailing speed during strong waves and winds.This phenomenon is called “load fluctuation.” The shaft generator may also increase the burden on the main engine.
ClassNK in Joint Ship Design Project
ClassNK Starts Joint Research Project with Shipyards on Upgraded Design taking into consideration Ship's Performance in Actual Seas. ClassNK (Chairman and President: Noboru Ueda) has started full scale ship tests to develop a feedback scheme on the design for ships performances in actual seas in collaboration with IMABARI SHIPBUILDING CO.,LTD (President and Representative Director: Higaki Yukito) and SAYONAS SHIPBUILDING CO. (President and Representative Director: Ueda Takashi).
