Klaveness Combination Carriers (KCC) has extended a current contract of affreightment (COA) with Aussie metals and mining company South32.

The extension will see the Norwegian shipowner continue shipments of caustic soda to Worsley Alumina Pty Ltd, South32’s alumina refinery located in Western Australia.

Through this agreement the term of the COA is extended by three years from January 2019 to December 2021 with two one-year extension options, KCC said.
