An AP Moller-Maersk boxship is heading back to Asia after collecting nearly 8,000 empty containers from ports in Australia.

The 9,640-teu Soroe Maersk (built 1999) was deployed as an “empty sweeper” calling at Sydney and Melbourne.

The vessel travelled to Australia from Thailand, making its first call at Port Botany, Sydney, where it picked up an estimated 3,756 teu, or roughly 40% of its capacity, according to port operator NSW Ports.
