由韩国造船巨头大宇造船公司（Daewoo Shipbuilding）与海洋工程公司（Marine Engineering）建造完成的一艘新LNG运输船，交付给了希腊海运公司Maran Gas Maritime。

DSME表示，这艘由Maran Gas公司在2016年6月订购的173400立方米液化天然气运输船装有空气润滑系统。

空气润滑系统是一种节能技术，它将空气注入船的底部，在船体和海水之间形成一个连续的空气层，通过减少船在运行过程中产生的摩擦阻力来提高燃油效率。

装有该系统的LNG运输船与现有的LNG运输船相比，新船可以节省5%的燃料。运输船的平均运营时间为20年，这大约可以减少一年半的燃料成本。

据该公司介绍，这是该技术首次应用于新建的LNG运输船。之前该技术曾被用于集装箱船。

DSME补充道，新船的拥有者Maran Gas公司在10月份的试航中评估了该液化天然气船的性能，并要求将空气润滑技术应用于接下去要建造的运输船上。

大宇造船公司还为该船配备了综合控制系统，可以实时监控和有效管理相关数据，同时在任何海洋环境中保持燃油效率。

DSME表示，“随着LNG运输船的成功交付，公司已经巩固了其作为液化天然气运输船技术领导者的地位。基于这种建造经验，我们已经将这种技术用于超大型集装箱船、液化石油气运输船和中型油轮。”

需提醒的是，DSME公司在8月中旬从Maran Gas公司得到一份新的LNG运输船订单。该订单是一艘174,000 立方米 LNG船，将在Geoje Okpo造船厂建造，并在2021年第四季度交付给Maran Gas公司。

值得注意的是，Maran Gas公司已订购了DSME公司今年预建造7艘船中的6艘船。

Daewoo Shipbuilding delivers LNG carrier to Maran Gas

South Korea’s shipbuilding giant Daewoo Shipbuilding & Marine Engineering has built and delivered a new LNG carrier to Greek shipping company Maran Gas Maritime.

DSME said that the 173,400-cbm LNG carrier, ordered by Maran Gas in June 2016, was equipped with an air lubrication system.

The air lubrication system is one of the energy-saving technologies that injects air into the bottom of the ship to create a continuous air layer between the hull and seawater, improving fuel efficiency by reducing frictional resistance during operation.

This system could save five percent of fuel compared to existing LNG carriers. The average ship operation is 20 years, which can reduce fuel costs by about a year and a half.

According to the company, this is the first time this technology was applied to a newly built LNG carrier. It has previously been used on container ships.

DSME added that the vessel’s owner Maran Gas reviewed the LNG carrier’s performance during a trial run in October, and asked to apply the air lubrication technology to subsequent ships.

The company also equipped the vessel with an integrated control system that can monitor and effectively manage related data in real-time while maintaining fuel efficiency in any marine environment.

“With the successful delivery of ships, the company has solidified its position as a leader in LNG carrier technology. Based on this construction experience, we have used this technology for super-large container ships, LPG carriers, and medium tankers,” DSME said.

To remind, DSME booked a new LNG order from Maran Gas in mid-August. The order was for a 174,000 cbm LNG carrier which would be built at the Geoje Okpo shipyard and delivered to the owner by the fourth quarter of 2021.

It is worth noting that Maran Gas has ordered six out of the seven LNG carriers DSME booked this year.
