DSME develops LNG-fuel tank for cape ore carriers

DSME is putting spurs on development of eco-friendly technologies to comply with reinforced international environmental restrictions.

DSME unveiled on Oct. 12 that it has finalized development and design of MCTIB (high manganese cargo tank independent type-B) as LNG fuel tank for ore bulk carriers of 180,000dwt class, keeping pace with the growing number of very large bulkers which use LNG fuel tanks under the strengthened international environmental restrictions.

LNG fuel tank independently developed and designed by DSME for cape ore carriers uses high manganese (Mn) jointly developed by DSME and POSCO. It has strong structural feature against shocks that take place from pitches and rolls of liquid stored in MCTIB tanks as independent tank of Type-B. Notably, the LNG fuel tank that has applied high Mn has high impact-strength and can optimize space in comparison with the old fuel tanks that have used the existing aluminum in alloy. It can also halve the production cost, likely contributing to lift its competitive cost edge.

Also, LNG-fueled ore carrier developed by DSME has fuel tanks designed and installed on deck astern in the way that their required tank capacity can be flexibly controlled by each sailing condition without losing cargo. In addition, the carrier can have her reinforced hull structure installed as an optimized type in safety along with all kinds of fuel-saving devices. They are also designed most eco-friendly and energy-efficient, bracing up for environmental restrictions by burning LNG fuel to drastically reduce emission amount of CO2, S and nitrogen compound instead of the existing bunker fuel oil C.

A DSME official said: “DSME is fully lined up with LNG fuel tanks available for all types of LNG fuel tanks in addition to those for ultra-large box ships, tankers and LPG carriers. In this respect, the shipyard is expected to preoccupy the markets in receiving newbuilding orders ahead.”

Meanwhile, DSME is in the process of AIP certification on LNG fuel tanks for ore carriers following approvals by the world-prominent DNV-GL on designs of those ships using the same LNG fuel tanks, DSME added.
