China: Hantong Shipyard Splashes Bulk Carrier Columba

Recently the 57.000 DWT Bulk Carrier named Columba (HT093) was launched at Hantong shipyard’s slipway No.2. The vessel, built for Eagle Bulk and class approved by LR, is a new supramax bulk carrier optimised to burn less fuel oil.

The daily main engine consumption at a speed of 14 knots at ballast draft, which would have been about 29.4 tonnes, is now about 26 t and the daily main engine consumption at a speed of 13.5 knots at design draft, which would have been about 29.8 t daily, is now about 26.30 t. The engine’s output has been reduced by nearly 1,000 KW to 8,500 KW.

The efficiency improvements have been achieved by carrying out a number of straightforward – but effective – changes including: de-rating the main engine, a new propeller design which has been optimised for the de-rated engine, and fitting a mewis duct.

Vessel Particulars:

Gross tonnage – 32,913 t

Summer DWT – 57,000 t

Length – 190

Beam – 32 m

Draught – 13.1 m

Jiangsu Hantong Ship Heavy Industry Co (HTS) is a newly-built large and medium-sized enterprise. The shipyard gained the accreditation of ISO9001:2002 and OSAH14000/GB25008 the quality management system and is engaged in the construction of large vessels and ocean engineering units approved by Class like ABS、DNV、BV、LR、CCS.
