The world's largest ethane/ethylene carrier is on the way

ABS Grants AIP for the World’s Largest Ethane/Ethylene Carrier

ABS has granted Approval in Principle (AIP) to Daewoo Shipbuilding and Marine Engineering Co. Ltd. (DSME) for what it could be the largest Ethane/Ethylene Carrier ever built.
Under this design, the IMO Type B cargo tanks would be constructed out of High Manganese Austenitic Steel (Hi-MN Steel), which DSME says is more cost competitive than Ni alloy steel as well as providing increased reliability and a more robust containment.

These new cryogenic materials together with the most advanced technology provided by DSME are projecting new giants for the gas industry, increasingly booming. The viability of these applications for Type B cargo tanks were previously evaluated by both companies to confirm that the system will comply with current ABS rules.
