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.
"KCC’s CLEANBU service to Australia will meet demands for a reliable and substantially more climate-friendly solution for CPP [clean petroleum products] transportation," Dahm said on Wednesday.
"Through its unique design and trading pattern, the CLEANBUs will secure a 30-40% reduction in CO2, SOx and NOx emissions compared to standard tankers.”
One CLEANBU combination carrier has already been delivered to KCC from China's New Yangzijiang shipyard, with five more to follow between May this year and October 2020.
The vessels are designed to carry clean petroleum products and caustic soda solution, as well as dry cargoes.
KCC's existing fleet of nine CABU vessels, meanwhile, are designed to carry heavy liquid cargoes like caustic soda solution in addition to dry bulk.
The value of the COA was not disclosed.
Torvald Klaveness' combination carrier activities were consolidated into holding company KCC in 2018, which the group described in its results as an "eventful year".
