DSME tests ice-breaking LNG carriers’ durability

South Korea’s Daewoo Shipbuilding & Marine Engineering completed an impact test for the ice-breaking LNG carriers on order at its Okpo shipyard. 

According to a company’s statement on Wednesday, the impact tests were carried out for three weeks during October.

The LNG shipbuilder constructed blocks of similar structure and size to its ice-breaking vessels and applied impact to it by dropping one a seven-ton steel pendulums onto the structure from varying heights, simulating the impact of 2-meter thick ice sheets, the statement said.

No cracks in the welding have occurred following impacts from a height of 5 to 7 meters  for a one-ton, and 1 to 2 meters for a seven-ton pendulum, it added.

DSME won orders for 15 ice-breaking liquefied natural gas carriers in 2014. The vessels are planned to serve the Novatek-operated Yamal LNG project and will operate in conditions with ice thickness of 2.5 meters and in -45°C ambient temperature.
