Klaveness Combination Carriers' (KCC) newbuildings have employment lined up with an Australian importer and distributor of clean petroleum products on their delivery.

The CLEANBU vessels will this quarter begin a contract of affreightment (COA) with the unnamed importer for up to 12 months, during which multiple cargoes will be carried.

Engebret Dahm, managing director of the Oslo-listed company, said the COA was an "important milestone" for the vessels and their design concept.
