Daewoo Shipbuilding & Marine Engineering (DSME) has proven its world's top technological prowess by completing patent registration for the cargo window of the super-large-sized crude carrier. It has been carrying out patent applications for eight major countries in the world since 2010.

DSME said on Sept. 5 that it has recently completed registering its final patent on a cargo window to which crosstie has not been applied.

The crosstie is a component that has traditionally been installed to support the bulkhead barrier from various loads imposed on cargo windows of super-size crude carriers with a height of more than 25 meters.

In order to install the crosstie, workers had to work on the tread plates installed in the air, facing both large and small risks, and spent a lot of time and money during the manufacturing and drying process.

To solve this problem, DSME has been developing a freight window without crosstie since 2009 through a shift in its thinking. Since 2011, it has been applying the cargo window without crosstie to the super-size crude carrier.

DSME has applied for patents with the technology to patent offices in eight countries around the world since 2010. Starting with patent registration in Japan in 2015, patent registration was completed in the U.S., four European countries and China in 2016.

And as the final patent registration was completed in Korea in July, its patent registration was completed in a total of eight countries, including the United States, Japan, China, Greece, Britain, Norway and France, and the Republic of Korea.
