DALIAN Shipbuilding Industry China (DSIC), Dalian Ocean Shipping and Lloyd's Register, have completed a joint industry project to develop a minimum ballast very large crude carrier," reports London's Tanker Operator.
The partners have since continued to develop a further detailed designs to provide a series of reduced ballast Suezmax and Aframax tanker designs.
The "Clear Advantage" reduced ballast designs provide substantial performance improvements over conventional tanker designs, the partners said, without describing the method employed.
The benefits are said to be reduction fuel consumption during ballast passages; a reduction in ballast water treatment capacity, and time, energy and penalties as well as a reduction damage done by mud or silt.
Mud and silt are significant operational realities in China where terminals are on river banks. Intake of river water ballast during cargo discharge can result in substantial volumes of mud or silt accumulating after operations leading to as much as 1,000 tonnes becoming stuck in ballast water tanks.
The combined impact of the loss of cargo capacity, the economic drain of transporting the mud during laden passages and the eventual cost of removing the muddy slurry, as well as the strain on ballast water treatment systems have all been reduced in the new "Clear Advantage" designs.
