Its cargo can load over 800,000 barrels of either product oil or crude oil products. This series of vessels’ verified EEDI has achieved the International Maritime Organization (IMO) in the third phase of 2025 ahead of schedule through comprehensive optimization of hydrodynamic performance, arrangement of hydrodynamic energy-saving ducts and vortex fins, and optimization of main engine selection. At the same time, its emission of nitrogen oxides meets the requirements of Tier III, and the emission of sulfur oxides fulfills the requirement of 0.1%.

Aframax oil tanker is another great effort of SWS to expand new brand ship types in the field of merchant vessels.
