SX CLASS VESSELS
These container carriers are advanced ‘SX’ class vessels, boasting the largest declared capacity in the world, at 8,063 TEUs. They are also the largest vessel ever built by Samsung Heavy Industries.
The new generation SX-class vessel is designed with many environmentally-friendly features including specially designed hull which allows the vessel to consume less fuel while maintaining a very high speed of 25 knots per hour. The vessel is also designed to burn low sulphur fuel with much reduced SOx gases emission to the environment. Tin-free SPC paint is used to reduce toxicity to marine life.
The design has a double hull arrangement, with the side, bilge and three transverse bottom tanks being used for water ballast and bunker capacity. Heel adjustment is provided by two side tanks, with a heeling pump linked to an automatic system being used for transferring the ballast water across.
