石油设备网讯 据世界天然气网站8月5日消息 日本造船厂山崎汽船株式会社（K Line）与日本名村造船所就挪威船级社（DNV GL）的液化天然气矿石船概念设计获得了原则上批准(AIP)。
K Line周一表示，开发液化天然气矿船的联合项目符合第二代WOZMAX船舶的环境和实际操作要求。
以液化天然气为燃料的矿石船将保持与WOZMAX船几乎相同的自重（25万载重吨）和正常工作速度，并具有足够的续航力，以便在天然气燃料模式下往返新加坡和巴西，该船将液化天然气储罐布置在船体的中心位置。
该船还将通过改变液化天然气的一次燃料，实现第三阶段能效设计指数（EEDI）。
除了液化天然气燃料转换外，K Line还研究了将其与轴流发电机、二元循环发电系统和锂电池相结合以进一步减少二氧化碳排放的可能性。通过这些添加，系统可以进一步降低燃油消耗量的4%。
该系统被认为是有助于公司在2050年实现目标的有效系统之一。

K Line, Namura pick up AIP for LNG-fuelled ore carrier concept
Japanese shipbuilder Kawasaki Kisen Kaisha (K Line) has received a joint approval in principle (AIP) with compatriot Namura Shipbuilding for the concept design of an LNG-fuelled ore carrier from DNV GL.
K Line said on Monday that the work on this joint project for the development of an LNG-fuelled ore carrier complied with both environmental and actual operation requirements of second-generation WOZMAX vessels.
The LNG-fuelled ore carrier will keep almost same deadweight (250,000 dwt) and normal service speed as a WOZMAX vessel and will have enough endurance for a round-trip between Singapore and Brazil in gas fuel mode, arranging the LNG tanks in the center section of the hull.
The vessel will also achieve a Phase 3 energy efficiency design index (EEDI) by means of primary fuel changes to LNG.
In addition to LNG fuel conversion, K Line studied the possibility of it being combined with a shaft generator, binary cycle power generation system, and a lithium battery to further reduce CO2 emissions. With these additions, the system can achieve an additional further four percent reduction of fuel oil consumption.
This system is considered as one of the efficient systems that will help us achieve our goals by 2050.
