The first vessel in a new series of supramax bulk carrier designs has been optimised to burn less fuel by adopting a number of effective changes: de-rating the main engine, a new propeller design that has been optimised for the de-rated engine, and fitting a mewis duct.
The daily main engine consumption at a speed of 14 knots at ballast draught, which would have been about 29.4 tonnes, is now about 26 tonnes; the daily main engine consumption at a speed of 13.5 knots at design draught, which would have been about 29.8 tonnes daily, is now about 26.30 tonnes. The engine’s output has been reduced by nearly 1,000 KW to 8,500 KW.
According to the ship designers SDARI the structure of this new type BC57K has been optimised, satisfying the latest requirements in the Common Structural Rules for bulk carriers, especially to accommodate the severe strength requirement of steel coils. The new ship will be able to load about 54,000 tonnes of steel coils during one voyage with little increase of light weight. The vessel also meets the requirements of EEDI-PHASE I.
