LNG作为船用燃料具有高热值、低排放特性，是解决排放问题的最实施可行方案之一。全面限排法规临近实施，越来越多船东青睐于在新造船阶段增加LNG-ready设计,具备将来可直接改装为双燃料动力的灵活性。依托大连船舶重工集团LNG-ready实船项目,研究并归纳了大型远洋成品油船加装LNG-ready设计的基本设计流程和关键技术路径,旨在为国内外船舶设计行业提供借鉴和参考。

LNG has the high calorific value and low emission characteristics as ship fuel, so it is one of the most feasible method to solve the emission problem. With the limit emission rules carryed out, more and more owners tend to add the LNG-ready design in the new shipbuilding stage, therefore the ship will be flexible to be retrofitted to dual-fuel power directly. This paper shows the basic design flow and key technical routes about LNG-ready design on large ocean products oil tanker, based on the real ship LNG-ready design project delivered by Dalian Shipbuilding Industry Co.，Ltd., which will be a reference for domestic and foreign ship design industry.
