Zeamarine has inked its largest contract to date with the business set to employ its latest newbuildings.

The contract with Schenker Australia will see the Zeaborn unit carry 450,000 freight tons from China to Western Australia.

Its ZEA-type 14,900-dwt newbuildings will undertake the work, with Zeamarine chief commercial officer Dominik Stehle stressing the ships are proving to be a valuable asset.

The cargo will go to BHP South Flank Project in the Pilbara, which will become one of the largest integrated mine sites in the world.

Frank Vogel, director projects at Schenker Australia, said the owner was selected due to the "brand new fleet of environmentally friendly vessels that will be utilized".

The contract comes just a few days after BHP announced a $400m climate change plan as part of its long-term 'zero emissions' goal.

Zeamarine has a fleet of 90 multipurpose heavy lift vessels.
