据世界天然气网站1月3日报道，由总部位于雅典的Arista Shipping领导的Project Forward计划已获得韩国知识产权局审查员的专利。

正在申请专利的机械装置包括两个低压四冲程瓦锡兰31Dual燃料主发动机和两个PTO / PTI，它们连接在一个驱动CPP螺旋桨的轴上。

该项目概念船的模型试验表明，能效设计指数（EEDI）远低于目前最严格的第三阶段水平。EEDI第三阶段适用于2025年以后建造的船舶，比2008年的参考水平减少了30％。

国际海事组织还表示，应该努力在2050年之前将每次运输工作的二氧化碳排放量进一步降低70％。

Project Forward表明，通过使用混有LNG的碳中性燃料，即使不降低服务速度，也可以实现减少70％的二氧化碳排放目标。这种碳中性燃料的运输、储存和消耗方式与化石液化天然气类似。

概念船的船体形式已经与芬兰船舶设计师Deltamarin和美国船级社(ABS)合作进行了优化。

除了Arista Shipping，Deltamarin，ABS和W?rtsil?之外，法国液化天然气膜控制系统设计师GTT也参与了该项目。

Project Forward’s LNG-fueled bulkers granted South Korean patent

The Project Forward initiative led by Athens-based Arista Shipping, has been granted a patent from the South Korean Intellectual Property Office Examiner.

The patent-pending machinery arrangement consists of two low-pressure, four-stroke W?rtsil? 31Dual Fuel main engines and two PTO/PTIs, coupled on one shaft that drives a CPP propeller.

Model tests of the project’s concept vessel indicate that the Energy Efficiency Design Index (EEDI) is well below the currently most stringent Phase III level. EEDI Phase III is applicable to ships built after 2025 and signifies a 30 percent reduction from the 2008 reference level.

The IMO has also said that efforts should be made for a possible further reduction in CO2 emissions per transport work of up to 70 percent by 2050.

Project Forward shows that this 70 percent reduction in CO2 emissions target can be met, even without lowering service speeds, through the use of carbon-neutral fuels mixed with LNG. Such carbon neutral fuels can be transported, stored, and consumed in a similar way to that of fossil LNG.

The concept vessel’s hull form has been optimized in cooperation with Finnish ship designer Deltamarin and classification society American Bureau of Shipping (ABS).

In addition to Arista Shipping, Deltamarin, ABS and W?rtsil?, the French LNG membrane containment system designer GTT is also involved in the project.
