达飞CMA CGM成为世界上第一个为超大型船舶采用液化天然气（LNG）燃料推进的航运公司，其最近下单的9艘22000 TEU超大型双燃料集装箱船入级BV。
据了解，使用LNG作为新集装箱船的燃料是经过深入论证后的决定，船东、船厂、供应商以及BV为此进行了详细的可行性研究。
这批新订单标志着集装箱市场的一个显着提升，薄膜系统的规模和使用上都实现了一个巨大突破。为目前为止最大的双燃料发动机所提供燃料的燃料舱，其容量将接近18000立方米，远远高于迄今为止LNG燃料船所需的容量。
BV在早期阶段为该项目给予了全力支持，确保该系列船舶所需LNG的安全使用。这项工作的一个重要部分，就是和中国船舶工业集团公司及货物系统的设计方GTT，共同研究设计的可行性。
BV在大型集装箱船的设计和建造上积累了丰富的经验。其最近发布了一份超大型集装箱船的技术报告，包括三个主题：货运能力的优化和操作；LNG推进系统，内容涵盖货物围护系统及加注；以及更安全、更高效的船体结构规则。
该系列船入级BV也凸显出了BV在LNG燃料船舶入级的领先地位。据统计，BV目前在LNG燃料船舶上拥有世界上最大的份额。
随着整个天然气供应链的需求增长，BV专家广泛参与了世界范围内的LNG项目，包括与LNG供应商、港口当局和挂国旗在LNG加注操作方面进行合作。这些项目涵盖了小型LNG船、LNG燃料项目以及LNG运输船舶，包括为Yamal入级的15艘冰级船舶。
CMA CGM CONTAINER MEGA-SHIPS GO WITH GAS
The final decision to use LNG as fuel for the new 22,000 TEU containerships was carefully considered, with Bureau Veritas closely involved in feasibility studies, working with the owner, builders and technology providers.
In addition to providing a significant boost to the containership market, the order represents a breakthrough in both scale and use of a membrane containment system. The new ships’ bunker capacity, feeding the most powerful dual-fuel engine built so far, will be close to 18,000 m3 – a far higher volume than has been required to date by the LNG fuelled ship market.
Bureau Veritas has supported the project throughout its early stages, providing assistance to ensure the requirements for the safe use of LNG are addressed. An important part of this work involved investigating the feasibility of the design together with shipbuilding group China State Shipbuilding Corporation and GTT, the containment system designer.
Bureau Veritas has extensive experience in addressing the challenges of large containership design and construction. It recently published a technology report (“Ultra-Large Containerships”) exploring three topics: optimized cargo capacity and operations; LNG propulsion, including cargo containment and bunkering; and new rules for safer, more efficient hull structures.
The award of class to Bureau Veritas also underlines our leadership in the classification of LNG fuelled ships. BV currently has the largest share for vessels with this type of propulsion.
Further upstream, with growing demand across the entire gas supply chain, Bureau Veritas specialists are involved in a wide range of LNG projects worldwide, covering also the bunkering operations and working closely with LNG suppliers, port authorities and flag states. These range from small-scale LNG vessels to LNG as fuel projects and LNG carriers including 15 ice-class ships for the Yamal project.
