Research On The Issues Of Green Technology In The Ship Life Cycle

Green ship is a comprehensive concept that throughout new ship design, construction, operation of ships sailing to the port and terminal handling, aging ship conversion, ship dismantling scrapped.Green Ship have the least harmful to environment of atmosphere, soil and water,its consumer least of resources.Green ship with the advanced technical,good economy and friendly environmental protection, its most important energy saving feature is the essence of the ship is reflected in the design, construction, operation, demolition and other areas, and continue the use of advanced environmental technology to improve the ship's green degrees.In this paper, energy saving and environmental protection as a starting point to investigate the green ship design, construction, operation, dismantling the whole life cycle. And put forward the content of green ship design, ship structural optimization in the design layout, select green materials, power equipment, which is the key to achieving the green ship.This article choose 6800DWT class of river transport vessel as the study purpose, the series of shallow draft ship Two fin mast linear optimization, the bulbous's line choice, energy saving and energy-saving attachments with ballast water system design in-depth study for the future development of green hull form and lay a solid foundation.Ship-builting should pay attention to environment-friendly green spaces construction insulation material, green solder materials, non-toxic green paint and other choose to use green materials. Good production design and processing of marine green, green coating process and welding,which is helpful to improve operational efficiency and reduce waste of resources.Finally, we discuss the main contents of PSPC, the implementation of the standard coating IMO PSPC, PSPC and the current implementation of standards for the implementation of the main problems facing PSPC.Study the scope of the operation index of energy efficiency,the equation and CO2 emission factor for analysis, and export the EEOI estimation formula of container ship. Based on the collected six ocean-going container vessels typical data, calculate each vessel EEOI, analyzed the factors,which are container ships, model, speed, packing rates, range and time,have impact on the EEOI of Ships.In addition to the contact oxidation process by sewage from ships and selective catalytic reduction (SCR) processing engine to study the effects of pollutants discharged.And elaborate the importance of green ship recycling, measures to prevent environmental pollution scrapping, scrapping generated pollutants and their hazards, the order and green technology of removal the pollutants, ship-breaking and dismantling and crafts.
