21万吨散货船LNG燃料罐鞍座安全性能评估

The Safety Performance Evaluation of Saddle of 210,000-ton Bulk Carrier LNG Fuel Tank

21万吨散货船是常规船型,搭载LNG(液化天然气)动力系统,船舶油耗和动力方面会更有竞争力。LNG燃料罐会受到船舶运动、自身重量、温度场、风力等多种环境条件和力的影响,鞍座作为其主要的支撑结构,是保障LNG燃料罐安全的唯一有效措施。保证鞍座的安全性能是搭载LNG动力系统的必要措施,该研究已经取得LR(英国劳氏)船级社的认可。

The 210,000-ton bulk carrier is a conventional ship type equipped with an LNG(liquefied natural gas)power system,which makes the ship more competitive in terms of fuel consumption and power.LNG fuel tanks are affected by various environmental conditions and forces such as ship movement,weight,temperature field,wind force,etc.The saddle,as its main support structure,is the only effective measure to ensure the safety of LNG fuel tanks.Ensuring the safety performance of the saddle is a necessary measure for carrying an LNG power system,and this research has been recognized by LR(Lloyd's Register of Shipping).
