A 14% reduction in fuel oil consumption has been confirmed in a new bulk carrier delivered yesterday to operator Delphin at Jiangsu Hantong (HTS) in China.
Lloyd’s Register supervised the design appraisal, build and sea trials, verifying the performance of a new, modified 57,000 dwt ship based on a SDARI design
The M.V. Aquila, first in a new series of supramax bulk carrier designs, optimised to burn less fuel oil has been delivered in China on the eve of the Lunar New Year holidays. 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.
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 tonnes and the daily main engine consumption at a speed of 13.5 knots at design draft, 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.
Commenting on the delivery, Meng Cheng Jun, President of the Jiangsu Hantong Group, said that: “This vessel is the fifty-fifth vessel to be delivered since the establishment of our Hantong shipyard, and also the first vessel with the optimized design to be delivered. Based on the SDARI design, Hantong completed the design optimisation and the tank test independently, which also brings us the patent right of our own part. Hantong is taking note of the market environment requests and listening to the owners’ needs on vessels, now therefore, Hantong will keep on strengthening the optimisations of our vessels, and is endeavouring in building the vessels to be eco-friendly and more fuel efficient than previous ones, for our honourable clients.”
