摘要

为有效利用液化天然气（LNG）船舶运营过程中产生的大量蒸发气（BOG），研究了考虑BOG管理的LNG海上运输航线配船问题。以LNG产生的BOG作为推进燃料，建立经济航速下LNG海上运输航线配船模型。在此基础上，结合航速与BOG需求量的关系设计BOG管理策略，进而建立考虑BOG管理的LNG海上运输航线配船与航速联合优化模型。以我国一家LNG航运企业为例，求得两个模型对应的最低成本、最优配船方案与航次计划。对比两个模型的最优解可知，BOG管理策略能够有效降低8%以上的成本，并从LNG现货价波动与航运企业的业务规模角度提出相应的管理建议。研究结果表明，该方法能够为LNG航运企业合理配置运力资源、有效管理LNG船舶蒸发气提供决策支持。

Abstract

In order to effectively utilize the large amount of boil off gas (BOG) generated during the operation of liquefied natural gas (LNG) ships, the ship allocation problem for LNG sea transportation routes considering BOG management was studied. A ship allocation model was established for LNG sea transportation routes at economical speeds using BOG generated from LNG as propulsion fuel. On this basis, a BOG management strategy was designed based on the relationship between ship speed and BOG demand, while a joint optimization model for LNG sea transportation route allocation and ship speed considering BOG management was established. Taking an LNG shipping company in China as an example, the lowest cost, optimal ship allocation plan, and voyage schedule corresponding to two models were obtained. Comparing the optimal solutions of the two models, it can be seen that the BOG management strategy can effectively reduce costs by more than 8%, while corresponding management suggestions are proposed from the perspective of LNG spot price fluctuations and the business scale of shipping companies. Research results show that the proposed method can provide decision support for LNG shipping companies to reasonably allocate transportation resources and effectively manage LNG ship evaporation gas.

Key words： LNG sea transportation; route allocation of ships; boil off gas (BOG) management; speed optimization
