South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering Co. Ltd. (DSME) has secured an Approval in Principle (AIP) by ABS for the design of what it is claimed as the world’s largest Ethane/Ethylene Carrier.
Under DSME’s 165,000 CBM Jumbo Ethane/Ethylene Carrier 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.
Based on DSME’s advanced technology, which is performing strongly in the LNGC market, it will be able to lead the global gas market not only in membrane but also in Type B tanks by developing this new design for ultra-large Ethane/Ethylene carriers, applying high-manganese steel, a newly rising cryogenic material,
…said Odin Kwon, Chief Technology Officer of DSME.
ABS has reviewed the feasibility of the Type B cargo tank design based on information supplied by DSME to confirm the system would comply with current ABS Rules.
ABS and DSME have previously collaborated on Joint Development Projects assessing the viability of Hi-Mn Steel for cryogenic applications.
