The Company places great emphasis on prevention of pollution caused by newly-built vessels to meet the requirements of the conventions and norms such as Appendix VI of MARPOL. Before Appendix VI took effect on May 19, 2005, the Newly-built Vessel Projects, such as 5100 TEUs and 10000 TEUs ordered by the Company, were paid attention and measures such as adopting low sulfur oil cabins were taken to meet the requirements of the conventions. All the 10000 TEU carriers of the Company attained the high-grade “Environmental Protection” classification symbol assessed and issued by the classification societies they belonged to and set example for vessel building afterwards. Attaining the high grade “Environmental Protection” classification symbolizes that the vessel causes the minimum environmental pollution. Although not required by the international convention organizations, the symbol is admitted by the industry and requires additional investment into the environmental protection technology. With the increasing concern on the oceanic creature pollution caused by organotin, the International Maritime Organization has forbid use of antifouling paints with organotin since 2003. And all the vessels are forbidden to use paints with organotin in 2008. On principle of emphasizing oceanic environmental protection, the Company decided to paint newly-built vessels with TBT-FREE or silicon vanish in spite of greatly increased cost. In order to protect the layer of ozone, at the meeting of the treaty powers of the Montreal Protocol in 1992, the applied volume of chlorofluorocarbon was revised and production and application of CFC were to be abolished since 1996. In order to meet the requirement of the Convention, condensing agent of no damage to the layer of ozone and of high refrigeration and heating efficiency are adopted into the vessel-applied air conditioners and refrigerating engines. Under the circumstances of fuel shortage and increased energy crisis, the Company pays more attention to the energy-saving requirements for the newly-built vessel, making every effort to build vessels with the lowest oil consumption at the same sailing speed. Take the 5446 TEU carrier for example. The engine adopts MAN B&W 10L90MC with daily oil consumption 150T, saving about 10T oil every day compared with other engines of the same power. In addition, Equipment such as ALPHA oil injector was applied in the newly-built vessels to boost full combustion of the fuel, which saves the energy to the utmost. The use life of the vessel owned by the Company is set shorter than 20 year. All the vessels out of commission are disposed of by selling.
