OMC International's Dynamic Under Keel Clearance (DUKC®) technology is making waves in providing a scientifically consistent approach to UKC tech. While serving a purpose of greater safety and efficiency, DUKC technology has a number of environmental benefits.
For the average iron ore vessel coming out of Pilbara Ports in Western Australia, DUKC® delivers an average benefit of 0.60m to 1.0m draft (vertical distance between the waterline and the bottom of the hull/keel). This allows ships to carry more cargo, meaning the average CO2 and GHG emissions per tonne of product shipped is reduced.
From OMC's website, 'the direct contribution of DUKC® is estimated to have reduced annual fuel costs for the iron ore exporters by USD$130m, and the CO2 emissions by 1.2m tonnes.'
The technology also reduces the amount of dredging required at ports which means less intrusion on surrounding marine ecosystems. The technology was used at Lyttelton Port which reduced dredging volume by 43% compared to alternative designs.
